Coco coir watering

Hi guys,

Growing some Autoflower Wicked Monkey and Dream Berry by caveman seeds
18h light cycle
Coco coir with 30% perlite
45-55% RH
1000w viraspectra LED
5.8-6.0 PH
Green planet 3 part feed + vitathrive + calmag
1.2x1.2x2 grow tent
6” exhaust fan (off most days)
1 little fan

Atm feeding Per litre
1ml calmag
1ml grow
1ml Micro
0.75ml Bloom
1ml vitathrive

So I see a lot of people saying you need 15% - 20% run off but I’m always too scared of over watering my plants

I give them about 2l of water every 2-3days and they are growing heaps everyday.

I have 2 plants in 20L pots and 2 in 16L pots

It’s my first grow and I wanted to try different sizes pots so I could choose what works best for me and stuff.

The big question is, should I aim for this 15-20% run off or the 2L every couple of days should be alright as long as they are not showing signs of under watering?



First I would like to welcome you to our world of growing here at ILGM and to our awesome community.

My Guide for growing on coco

Growing cannabis is a hobby that more and more people pursue. Everybody can have great
results if you adopt a professional attitude as grower. A good crop depends on the
commitment and cleverness of the caretaker.
This guide focuses on the growth of skunk and indica kinds, varying from 7 to 10 weeks
flowering phase.
There are various methods to grow professionally, but we have found that this is the
simplest method to yield results over the gram/watt. We know from experience that if
the beginner is serious and meticulous and visits the shop once every two weeks for
half an hour to catch up the first harvest will yield premium quality and premium production.
Failed harvests due to mistakes in the growing method are rare, but are caused by, for example,
unreliable equipment, low-quality products, nonchalance, and by insect plagues.
There are two differences:

  1. Coco in pots
  2. Coco in slabs
    The advantage of growing in pots is that you can move the plants during the harvest.
    Since one plant grows faster than the next it is easy to sort them according to length
    and order them in such a way that they catch as much light as possible. Coco slabs only
    offer advantages such as less work (primarily in larger areas) and less waste, and even
    higher yields if you use a water system. This guide only discusses the first method. For
    growing on slabs, go to 38. Growside Maastricht V.O.F… We only explain the method
    of growing and not the layout of the room. Visit the shop for advice on how to do this,
    because the layout requires special attention, for example isolation, ventilation and
    power supply.
    Coco in pots
    In order to reduce the harvest time as much as possible to prevent the development of
    problems we use a 4-litre pot of lxbxh is 15x15x20cm. Citral, Peacemaker, White Widow,
    Snowball, Santa Maria or other white weeds barely need to be given growing time
    (18 hours light or more) if the climate is really damp the first two weeks. A K2 or a
    Top-44 for example, are slow growers that can take at least five days of growth.
    Since the plants do not or barely get the time to grow, they will yield a maximum of
    25 grams on average. That means that at least 24 plants must be placed under every
    600w lamp in order to yield 600 grams per 600 watt HPS lamp. Because the artificial
    light is less powerful than the sun the intensity of light greatly decreases if the
    distance between lamp and plant becomes a bit bigger. For that reason a short plant
    usually has long full flowers from top to bottom and a long plant may look deserted
    of flowers especially at the bottom. A larger plant (larger than 75cm) does not yield
    more than a smaller one and is unmanageable.
    Ordering and comparing pots
    A big advantage of growing with pots is that you can move the plants and can look per
    plant if it needs water or not. Especially the first three weeks there can be large
    differences between the plants, which are caused as follows:

The cuttings you start with are different. It is possible that one has grown 15 cm after
5 days and has already used a lot of water while another is still as small and damp as in
the beginning. If you water all plants while some of them are still wet you drown the plants
that were already small while the cuttings that are big get watered at the correct moment.
The large plants will grow even harder and the small ones even slower and the differences
will keep getting bigger and bigger. For that reason you should only water plants that are
The more often you select, the more evenly your plants grow. When your harvest progresses
you often see that the plants become more yellow in the centre than at the side, because
the plants in the centre receive more light energy and process the food more quickly and
therefore use more food. If you put a yellow plant on the outside you give it some time
to take in food and become greener again. This means that a plant that is green
(a plant with much unprocessed food) processes more food under the light than a plant
that is already yellow because it cannot supply the food quickly enough.
Moving lamps or moving the lamps somewhat is always better.
One of the most underestimated factors in indoor growing is the humidity.
It is important for the further course of the entire harvest especially the first three weeks.
A cutting is a sprig of a plant with a few leaves, which is cut from a large plant, the
mother plant. This mother plant is selected on quality, gender, and strength and each
cutting from this plant has exactly the same characteristics, the genetic factors. Since
this cutting can vaporize water via the leaves, but cannot absorb water (there are no leaves)
it must be protected against dehydration. This is where humidity comes into play. By
increasing the humidity the water will vaporize more slowly and the plant will loose less
water than in dry air. You give the plant more time to grow roots this way. With the help
of the humidity you can actually regulate the rate of water evaporation in the plant. Even
if roots are already there it may be that a young or sick plant cannot keep pace with the
evaporation, for example if the amount of light or warmth is increased. You can recognise
it by more yellow leaves, dried out edges of leaves, a stagnating growth and a decreasing
Most of the time when you turn on the light the room will get too dry quickly.
Since cuttings will usually take root under strip lights they are not used to really
strong light.
Initially hang the lamp(s) as high as possible, start with a few lamps and add more
lamps in the course of the first two weeks. Much light means much warmth. Much warmth
means much extraction to lead away the warmth and all humid air is transported outside.
Everyone will see the similarity between a blow-drier and the warmth of the lamps in
combination with the extraction. The more lamps, the warmer it gets, the stronger the
extraction so the lower the humidity, or the dryer the air. In order to maintain a
high level of humidity you must not use too much light initially so that the extraction
can be kept low. You can furthermore place water reservoirs, spray water, hang wet laundry
in your growing room or, even better, use a humidifier. Be careful that the humidity is
not more than 95% with reference to the electric equipment. When the plants get bigger
they will automatically use more water and give off more moisture to the air and eventually
the humidity will stay sufficiently high. When the humidity gets too high you can turn on
more lamps and/or increase ventilation.

The following values are advisable:
week 1 80 to 90%
week 2 70 to 80%
week 3 65 to 70%
week 4 through 8 60 to 65%
week 9 around the 55%
Nowadays there are various convenient climate controllers available that simplify the
controlling of your climate. Let someone inform you about the differences.
When you grow you will be visited by uninvited insects now and again. The cleaner you work,
the better, but it still does not guarantee anything. There will be no flowers the first
three weeks of the harvest. During this period you can use insecticide, which you wash
off before flower formation, without problems. I prefer insecticides that degrade themselves
within a few weeks and are not poisonous after that period. Let someone inform you about
this because there are also dangerous products on the market. Always ask about a product
that is suitable for vegetables, fruit and other consumer crops. A safety term is usually
also indicated. I furthermore advise to work with two different insecticides, one general
insecticide against louse, thrips and other insects and a special insecticide against red
spider mites (web). If you spray once every three days with one of the two insecticides
your crop will be clean before the real bloom. Primarily spray under the leaves.
Once you have an actual flower (and not the first hairs) you stop spraying and wash the
leaves a few times with a lot of clean water. You can also release natural enemies such
as predatory mites (orius) and soil-predatory mites (hypoaspis miles). The first lives
on all harmful insects on the leaves, and the other on all harmful insects in the soil
and for that reason they are particular suited to use preventively. Only tenacious red
spider mites might occur at the end of the harvest, against which you should use predatory
mites. It all seems a lot of work but it might save you a lot of problems, and fighting a
real plague is often more work and might cost more with reference to yield and quality.
Soil humidity

Watering with coco is different than with soil. If you grow on soil you cannot give the
plant too much water because the plant will drown otherwise. Much water in the soil
displaces all oxygen, which is rare in the ground in any case. Pearlite is added to the
soil to reduce this problem. Coco on the other hand is so light that there will always be
sufficient oxygen left and the plant cannot drown. This means in general that you can give
the plant so much water that it drains from under the pot each time. You can let the pot
become dryer the first week only to stimulate root development. You can also water the plants
on coco the soil-growing way (without drainage), but coco is actually a hydrological medium
and drainage yields better and more constant results (750grams/600watt/9weeks/1.2m2 has been
You furthermore compare the EC-values (see following chapter). If they are constant, flush
out a little and drain 20% nutrient solution. If you measure a higher EC-value you can
drain more (30%) and flush out more often. When the EC gets lower, you can give more nutrients.

Unfortunately I haven’t seen a professional soil humidity meter yet. The hydrological growing
on coco always enables you to know if you have watered the plant sufficiently. From the 8th
day you must find on average 25% of the water given each day in the waste water reservoir
where your drain water flows back to. You can furthermore decide at all times to give more
water in order to regulate your pH- and EC- values.
E.C. means Electric Conductivity, and is measured in uS/cm.
The dissolved salts in water determine the conductivity of the water. If no salts or minerals
are dissolved in the water the conductivity is zero, just like rubber. The more salts, the
better the conductivity. Tap water normally contains so many dissolved salts that it conducts
electricity dangerously well. Since most salts are also nutrient the EC.-value is also a
standard for the nutritional value of the water or the soil.
The EC.-value of the tap water in the Netherlands lies approximately between the 0.1 and
the 0.7 uS/cm. The EC in this area lies around 0.5. When we talk about an EC-value it is
always a combination of the EC-value of the water and of the nutrient. The tap water has
an EC-value of 0.5. In case of an EC of 1.7 this is 0.5 of the water and 1.2 enriched with
nutrient solution. In your case you must complement the EC of your tap water with 1.2 EC
nutrient solution.
When the plants are young you should work with an EC of 1.2, up to 1.7 in approximately
three weeks.
If everything goes as it should you determine by looking at the colour of the leaves if you
should give more or less nutrient. If the leaves are dark green this means that the plant
has more than enough nutrients for now. You can give fewer nutrients. If the leaves turn
more yellow, you can give the plant more nutrient. Since there are also other factors that
determine the colour of the leaves you should measure the soil or the drainage water.
Pay attention when measuring the pH and EC if you haven’t had constant drainage. The
values measured may be unreliable. You should flush a few days with extra drainage before
you start measuring (see Drainage).
A normal EC-value near the roots for an adult plant lies around 1.6 and 2.4 uS/cm.
Try to give a nutrient concentration as low as possible, but as much nutrient solution as
possible. Work with Citral and white weeds with EC-values between 1.6 and 1.8 if you
have 20 to 30 % drainage water left.
When you drain less, you must generally give more nutrients. With K2 or skunk kinds you
can often give more nutrients in any case.
With constant drainage you can use the drainage water to determine after the 3rd/4th week
how much nutrient you must give. We work with an EC between 1.6 and 1.8mS/cm.
Since the plant absorbs a part of the nutrients the drain water (waste water) contains
fewer nutrients than the nutrient solution. If you give 1.8, you can expect back between
1.1 and 1.6. If you have given, for example, 1.8 the previous weeks and measured 1.5 in
your drain water you can increase the nutrient solution 0.2 points when the EC-value of
the drain water drops to 1.3, for example. This is a sign that the plant develops well.
If the condition of the plant deteriorates due to, for example, high temperatures the
plant will also absorb fewer nutrients and you will measure a higher EC of the drain water.
This is a bad sign, which is often noticeable before other symptoms such as discoloured or
curly leaves.

You must lower the EC of your nutrient solution, and also look for the cause (bad climate,
bad pH or bugs).
On average you try to get an EC-value of 1.7 near the roots. The EC-value near the roots
lies around the EC of your nutrient solution and the drain water. All in all you can use
the following formula to determine the EC of your new nutrient solution:
EC of the new nutrient solution = 2 x [1.7 – (½ EC drain water)]. Here the EC drain water
is the EC of the old drain water left behind after previous watering(s).
Always watch the plant closely and never react rigorously. You should adjust your flush
water somewhat and use it to flush longer instead of flushing shorter with more extreme values.
If you measure an EC-value of the drain water that is higher than you have indicated on
the nutrient vessels you had too little drain or haven’t measured and adjusted often enough.
You can flush your coco on this moment until the values are ok again (see flushing). If your
plant stops growing due to stress it hardly uses nutrients. If you continue giving
nutrients without measuring almost all the nutrients you give will remain in the coco
and you will have an EC-value near the roots that will quickly get too high if you don’t drain.
If the leaves are yellow, do not increase your EC-values rigorously. Give a bit more
nutrients, but also water more often or give more water and during a longer period.
If you measure regularly you will never find strongly deviating drain values, and you
will only have to adjust minimally. Try to give a nutrient concentration that is as low
as possible, but give as much nutrient solution as possible.
EC-meters cost approximately Euro 40,-.
P.H. (Potentia Hydrogenica) is acidity. In plant breeding the pH determines the nutrient
absorption capacity. A pH that is too low (acid) causes certain elements to be absorbed
too quickly, which may cause poisoning. If you have a pH that is too high (basic) certain
elements will not be absorbed or with difficulty. A shortage is usually not caused by using
too little nutrients, but because the nutrients cannot be absorbed. You can have good nutrient
absorption on coco with a pH between 5.2 and 6.2 with a pH of 5.7 as ideal value.
Plants adapt to circumstances. For that reason constant values are always better. So keep
the pH constant!
The acids we use are nitric acid and phosphoric acid. Nitric acid or pH-grow (pH-min-grow)
is used in the growing phase and in the first week of the bloom, phosphoric acid or pH-bloom
(pH-min-bloom) is used after that. If the pH of your water with nutrients is lower
than 5.7 you need pH-plus. This is not acid, but a base, usually caustic potash.
Coco has, just like soil, the capacity to steer the pH, correct it and stabilise it.
This is caused by minerals in the coco that correct the pH. This means you can have at
least one harvest without regulating the pH of your nutrient solution. When you regulate,
up to 5 harvests are possible.
EC and pH are closely linked. If you add more nutrient to a bucket of water the pH
usually drops and if you add acid to the water the EC rises (a little). If you
continuously give a bit too much nutrient or if the plants absorb less nutrient the
EC-value in the coco builds up. The pH will also become more acidic (=lower).
If you grow hydrological on coco it is quite easy to maintain the correct pH-value
by means of the following formula:

PH of the new nutrient solution = 2 x [5.8 – (½ pH drain water)]. Here the pH drain
water is the pH of the old drain water left behind after previous watering(s). Test
your soil every three weeks or let a growshop check it. You can buy a pH-meter from Euro 40.
Good drainage prevents build up of acids and salts.
Drainage is the amount of nutrient solution that leaks from under a pot or slab after
fertilizing. The purpose of drainage is that the EC-and pH-values can be controlled
better and unnecessary salts are drained.
If you give a plant nutrient you try to give it exactly enough. Since not all plants use
similar amounts of nutrient and plants also secrete salts, there may be pots in which
salts are building up. This surplus of nutrient makes the soil brackish and changes the pH.
By means of drainage you flush the soil every time you give nutrient, which prevents the
soil becoming brackish.
If you measure the drainage water or the coco you can see if the soil is polluted. If
the EC is higher than you have indicated you must flush. You can also bring your water
or soil sample to the growshop. We can teach you there how you can carry out a proper
soil analysis and how you can determine from the values measured how to proceed. If the
values deviate strongly you can also, for example, flush half a vessel of nutrient
solution through the pots and measure again. If you still don’t have proper values
you can flush again a few days later. You can also slightly increase the drainage.
Try not to let the values fluctuate too much on 1 day, but flush with intervals of
a few days until the values are correct again. Too many fluctuations in a short while
can cause stress. Only measure drain water if you have regularly drained the past few
days, otherwise you measure unreliable values.
Step by Step
Day 1
-Heat up the room to about 24 °C.
-Regulate the humidity between 80 and 90%.
-Turn on as few lights as possible (for example 1). Hang the lamp(s) as high as possible.
-Minimise the extraction or turn it off (see chapter humidity).
-Fill the pots completely, lightly press the soil.
-Give half a litre of water per plant according to the “planting recipe”.
-Give all plants, within 10 minutes after placing, water because the dry coco otherwise
sucks the cutting plug dry.
-Spray water, so that the plants and the room are humid, but do not let the coco
become wetter with spray water because the pH of that water has not been regulated.

  • The blooming phase starts between now and 7 days depending on the kinds.

Week 1
-Keep the humidity over 80 % the first week.
-From the 2nd day preventively spray insecticide, every three days up to flower
formation and primarily under the leaves.
-When the plants have grown a few centimetres, you can select the plants on size.
Place the large plants on the outside and the small ones in the centre.
-The more often you do this the more equal the plants develop.
-After about a week (between 5 and 10 days) the plants need water.
-Use the “nutrient solution recipe 1”. Only water the plants that are dry and let
the others become dry first (see selecting and ordering plants).
-You can turn on about 2/3 of the lamps usually after a week.
This depends on:

  1. the regulation of the humidity and
  2. the development of the plants in the first week.
    Often these factors are connected.
    If the plants, for example, during planting or due to low humidity have sustained
    a shock it may be that they cannot stand so much light yet. In that case wait with
    increasing the amount of light, all the more since this also complicates a high humidity.

Week 2
-Keep the humidity between 70 and 80%.
-Keep spraying against insects.
-Order and select, in this phase only water plants that are dry, but generally
use a more humid pot for plants that do well. Water the plants with nutrient
1.-Slowly turn on and increase the air extractor (15 minutes/hour).
-Turn on the last lamps.
-Increase the extraction.

Week 3
-Keep the humidity between 65 and 70%.
-Gradually lower the lamps, 600wat min. 50cm and 400wat min. 40 cm.
-Give water according to nutrient solution-recipe
-Spray until the end of the week.
-Increase the extraction.

  • Spray the plants at the end of the week for the last time.
    This depends on the kind and how fast the bloom starts.
  • At the end of week 3 the soil humidity may rise until drainage starts.
    If the plants are relatively big you can drain sooner, and the other way round,
    because if the root system has not been developed enough yet a drier pot is
    better since the plant sends out the roots for water.
    Build up the drainage in the coming 2 weeks to at least 20%.
    Also mind the drainage water; you might for example discover harmful soil
    insects you don’t see usually. Of course you can also measure the water.
    The more the values (pH en EC) deviate from the nutrient solution, the more
    you must drain or flush. In case of large differences visit the growshop.
    -Order the natural enemies that you want to use preventively from the growshop.
    Assassin bugs and soil predatory mites are effective against practically all plagues.
    Only tenacious red spider mites may sometimes occur. In that case I use predatory
    mites, especially against the red spider mite.

part 2

Week 4
-Reduce the humidity from 65% to 60% in the course of 4 weeks.
-Do not spray.
-Collect insects ordered last week and use them
-Maximum extraction.
-Lamps at the minimum distance.
-Water plants according to nutrient solution-recipe 3.

  • Look for harmful insects.

Week 5
-Humidity approximately 60%
-Water according to nutrient solution-recipe 3.

  • Look for harmful insects.
    -Clear away all dead leaves that have fallen (and other mess).
    -Check the colour of the leaves and test the soil. When in doubt go to the growshop.

Week 6
– Humidity approximately 60%.

  • Water plants according to nutrient solution-recipe 3
  • Look for harmful insects.

Week 7

  • Humidity approximately 60%.
  • Water plants according to nutrient solution-recipe 3.
  • Look for harmful insects.
  • Clear away all dead leaves that have fallen (and other mess).

Week 8

  • Humidity approximately 60%.
  • Water plants according to nutrient solution-recipe 4.
    -Test the soil. If it contains a high concentration of salts the soil cannot be used
    for the next crop anymore, unless you flush out the salts. In this case flush with
    cannazym (until EC < 1.6). This loosens the blocked nutrient and also breaks down
    dead roots. Correct the pH with your flush water (if necessary).
  • Look for harmful insects.

Week 9
–Keep the humidity low to prevent fungus (=55%).

  • Water plants according to nutrient solution-recipe 4.
    -Check the biggest buds for fungus. Carefully bend a large bud open until you see the
    branch. Look for white or brown fungal hairs, brown and grey spots and slimy places.
    Usually a mouldy top also has parched, yellow or brown leaves. Look for fungus near
    an ugly leaf in the large tops. When in doubt show an affected top at the growshop.
    If you find fungus, it’s best to harvest at once since it might spread quickly.
    -If 2/3rd of the weed hairs are brown you can harvest.

Watering the plants
• Water is the source of life of a plant. One must be very precise here too.
• A few pointers:
• Temperature of the water is equal to the temperature of the soil (approximately 23° C).
• If you put out the water a day sooner, harmful chemicals such as chlorine vaporize.
• If you intend to regulate the ph of the nutrient solution you must do this the entire
harvest, every time you give nutrient or don’t do it the entire harvest. Keep the pH constant.
• Close the tap after you have finished!!!
• Never mix A and B without water.

Explanation of products used

  1. Canna coco A + B nutrient
    This is a ready-to-use 2-component nutrient for grow and bloom on coco. The
    nutrient regulates the pH a little so that it is unnecessary to regulate the pH yourself.
    Dose: between 1 and 4 ml per litre.
    EC- values between 1.2 and 2.4 cm/mS. dependent on the tap water and period.

  2. B’cuzz Coco Booster Indica
    This is a grow stimulator used in the first 4 weeks.
    It contains vitamins, amino acids, and other substances that, among other things,
    improve the metabolism and nutrient absorption via the roots.
    Dose: 1ml/l during the first 4 weeks.

  3. B’cuzz Root stimulatorThis stimulator stimulates root growth and is given
    the first 10 days.
    Dose: 1ml/l the first 10 days.

  4. B’cuzz Coco Bloom stimulatorThis bloom stimulator simplifies the production
    of bloom hormones and causes a quicker bloom. A plant that grows fast can remain
    small because it stops growing sooner. You usually use the bloom stimulator when
    you stop using the root stimulator.
    Dose: 1ml/l from day 12.

  5. pH - growThis is an acid (nitric acid) with a base of nitrogen. Since nitrogen
    is used a lot during growth it is the best acid to regulate the ph during growth.
    Dose: by means of pH-meter (pH between 5.2 and 6.2)

  6. pH –bloomThis acid has a base of phosphor (phosphoric acid). Since this is an
    important nutritious element during bloom it can be used to regulate the pH during
    Dose: by means of pH-meter (pH between 5.2 and 6.2).

  7. Co2-tabsThis is a pill that gives additional CO2 to your nutrient solution.
    Each organic molecule contains a carbon molecule © which the plant absorbs from
    the CO2.
    Dose: 1 pill per 100 litres of water.

  8. Masai Bayer anti-web for vegetables/fruit
    Insecticide purely against web (red spider mites). Especially spray under the leaves
    Dose: according to label

  9. Buzz off
    Biological insecticide against plant louse, thrips and other insects.
    Only use before flower formation.
    Dose: 1ml/litre preventive, up to 3 ml/litre maximum

  10. Cannazym
    This is a product to loosen the blocked nutrient in the coco with the intention to
    flush it out. It also accelerates the break down of organic remains (dead roots) in
    the soil.
    Dose: 2.5ml/litre

  11. Super thrive
    This product with a base of “growth hormone production stimulating” ingredients can
    be given during the first 4 weeks to plants that develop slowly and stay behind.
    Dose: daily 10 drops in 10 litres of water or 1/4ml / litre once only

Cutting and drying
During the last days you must try and regulate the soil humidity in such a way that
the soil is dry when you start cutting. If a lot of cutting is not a problem and if
you want to have optimal smell and taste you now only need to cut the plants below
the stem, and hang them upside down in the dark with a temperature of 18-20°C and
some ventilation (do not aim at plants). Regularly check the flowers for dryness
and fungus. Each bud with fungus must be removed from the room quickly and carefully.
When the stems are dry 10 to 20 days later you cut the leaves of the tops and afterwards
the tops from the stems. The buds must feel dry, but fatty now. Collect the leaves if
you want to make skuff later on. The flowers are now ready to be used or to be packed.
In practise few people seem to be working this way, often the end product is dried within
10 days and sold. Due to ignorance during drying you may loose taste and smell, but if
it’s dried the correct way this weed will also smell and taste great. Often the weed is
dried and packed after 8 days and ripens further in the bag, which causes chlorophyll
(leaf green) to break down in sugars, and the weed will taste optimally only after opening
the bag or preserving jar a week later. Especially the big growers cut the weed immediately
after harvest nowadays, and not after drying. The advantages are: less work, faster
drying, less risk, and the possibility to use electric cutters. These are economical
advantages as you can see, which are often more important to the bigger growers than
optimum quality. Here too it is optimal to have dry soil at harvesting day. First strip
the large leaves. These are the leaves without crystals and a long stem. Put the main
bud in your hand and pull the large leaves downwards. This way they break off along the
stem without leaving a stalk. You can throw away the leaves. The small leaves that are
left are covered by crystals which you can use to make skuff (Dutch hash) later on.
You subsequently cut the plant near the stem and cut the little hash-rich leaves with
small scissors (or electric cutter). Carefully collect these leaves and dry them in a
dark and dust free room for three weeks with a humidity of <50%. Hang the cut plant
upside down in the dark at a temperature of 18-20°C and a humidity of 55-60%.
Let the plants dry for 3 to 4 days, but do not let them become “crisp dry”. Cut the
flowers from the stems and place them on drying racks. Let the flowers become “crisp
dry” at the same conditions as before. Do not forget to turn the flowers now and again
to prevent fungus. If you think the weed is almost ready you put the flowers in a bag
or pot and check them every 12 hours. The remaining moisture spreads out equally through
the weed and it may feel moister than when you put it in. In that case remove the weed
from the jar or bag and dry it some more. You can repeat this process several times.
Preferably put too moist weed in the bag too soon than putting too dry weed in the bag
too late, because you can’t do anything then. You cannot make weed that is too dry
moist again. If the inner stalk of a large bud is dry, and the weed did not feel moister
after 24 hours in the bag the batch is usually ready to be packed. Try to prevent the
flowers from becoming too dry because that affects the quality and the yield. Since the
end product is a consumer product hygiene is not a luxury.


What he said… :point_up_2:
I was about to say the same thing… :joy::rofl::joy:
Welcome to the community!! :+1:t2: Good luck!



Thank you so much for that.

I’ve been researching for about 2 years before I started this grow. Mainly on YouTube and a few grow “guides”, but the depth you got in is incredible and I appreciate a lot that you share such knowledge.

I’ll print it all and will study it (might need a few puffs to digest it all haha). If I have any questions do I just tag you on this tread? I’m still trying to understand how the forum works.

Once more, thank you very much for all the info.

No problem at all any time you need just tag/…and there are many others that will be more than happy to help ya

B Safe

As always will gave more than enough info.

So I’ll buzz in here for a quick reply.
You don’t want to water your plants to runoff until they are big enough to handle that volume of water, your only doing water to run off 20% if feeding nutrients in soil or always in coco when in organic soil don’t do it unless your getting a run off sample as your watering out your organic microbes and nutrients.
That being said over watering in fabric pots is more of a water to often thing than it is a water to muhh at once thing, since they are fabric any excess just pours out of them.

Your going to need more light but don’t buy anything off amazon it’s all junk, if you want a good successful grow your going to need to spend more like 600$ Canadian on lights for 4 plants rather than 100$…you will struggle to get good buds with your current light even with only two plants. It will veg them good but come flower it’s just to weak so be prepared to save up for the next month and buy a good light or not get much bud.

Also once your plants get to the 4th node fim them, watch a YouTube how to FIM but your going to want to do this it evens out your canopy and thus improves your plants ability to equally absorb light Hus grow better buds and it also releases a bit of growth hormone since you stress them.

Make sure your reading your run off and following the ppm for your feed chart. Once the plants leaves touch the edge of the pot they are grown into the pot so be sure to water to 20% run off in order to avoid a salt build up of nutrients and thus have PH problems.
Look on Alibaba for kingbring, or buy from HLG, or worst case get spider farm but really you can connect a few pieces together and make your own for much much cheaper but go over to the lighting threads to see how to diy lighting.



Thank you for that. I’ll wait for them to be bigger to water them more.

I’ve been doing 1 water with Nutes and 1 with only phed water atm. Is that ok? Or better to just always feed them?

I might need to make do with the lights I have atm. Corona has hit our business hard here so money is a bit tight.

I might invest in something else for the next grow after this one is finished. Or I might get a small LED just to help out.

Regarding FIM, I thought it wasn’t a good idea as they are Autos but will definitely look into that. I was planning to do some LST to even out the canopy.


Also what light would you recommend from the ppl you mentioned? HLG and Kingbring (alibaba)

I have a Seahawk tent 1.2x1.2x2m
