So in the fear of overwatering I have been watering my seedlings 1 cup of water. It takes about 48 hours before they feel light and need water. The question is how much water should be coming out the bottom of the pot?
I have a very little water come out. Not enough to test runoff pH.
Should I increase the amount of water?

hey smokin ernie! what kind of medium are you using? my take is if it is running off it is hard to over water. i’m using sunshine#4 coco mix. i water until it drains out into my catch pots being sure not to go about half way up on saucers so i dont spill when i enpty on the next water. i hope this helps you,im new and learning everyday!

You should water till you have water drain off bottom of pots and then let soil dry out before watering again
Seedlings don’t need as much water
And water slowly
I hand water mine with a old school watering can 1/2 gal and test ph water as I go along i store my water In (1) 5 gal bucket with lid and (3) 1 gal bottles with caps in grow room so water is room temp when I use it
How old are you plants @Smokin_ernie

They are 19 days old today from sprouting. When I water I use a cup of water there is a bit of water that comes out the bottom but not enough to test pH. I use a solo cup over the plant and poor water over top of cup. It works pretty slick. I have already over watered but have recovered and just gun shy of doing it again. I also keep a gallon of water in room to keep it warm.

Sounds like your ok I don’t think you need to worry about run off just yet
But still water till you get a good run off not just a few drops
And wait till dry to water again it may take 2/3 days before you need to water due to size of your plants
Just go by feel of soil put finger in soil to first knuckle if it seems dry then water also feeling weight like you’ve been doing work also 
How this helps you out bud

@Countryboyjvd1971 thanks buddy yes helpful!! Right now they have an indirect fan on them and it is about 2 days in between watering. They dry out nicely.

Read another method, pertaining more to coco coir than soil, where you weigh your growing pot dry, and than weigh it again after watering, which of course will make it heavier. When the weight is half the heavier weight, time to water again. After seeing how long it takes for the pot to get to half weight, than you don’t have to weigh anymore, just go by the number of days it takes to dry out enough. Cool system, gonna try it!

That does sounds like a pretty slick technique.

So forgot all about this technique.@DieHigh55 I just transplanted to 3 gallon fabric pots. Which would have been a perfect dry weight.
I only watered them a little because of there size. No water came out the bottom. Should I water them until water comes out of the bottom? @Countryboyjvd1971 They are 35 days old from seed.
I would say yes water till water runs out bottom of pot and don’t water again till soil is dry Post pic so we can see her 
I would help us judge how to advise you and

Thanks will do when I get home from work.
(here is a post from a different site on watering… its a long read but worth it. the author is an old grey beard with lots of grows under his belt… been using these techniques and have had great results)
By Riddleme:
First let me say hello and tell you that you have come to the right place to learn to grow this wonderful plant, there is so much info here that it will easily overwhelm you.
There are so many different ways of growing, so many different styles of nutes, and mostly so many differing opinions. How do you, a new grower wade thru all of it and come away with a simple understanding of what is real and what is myth?
Not to worry as I have done it for you, when I came here I spent over 1000 hours just reading threads. I also purchased and read 45 books and I have over 20 dvd’s. Now I grew back in the day before all this designer stuff happened, so it was all new to me and even with experience I was overwhelmed. I decided to do several experiments to figure out on my own what was real and what was crap.
I am all about personal medical grows and showing folks how easy and cheap it is to grow your own medicine so for my first grow (to prove a point) I grew Matilda a 21 inch tall plant under one cfl with an added T9 (it was only 97 watts of light) I harvested 47.2 grams off her (1/2 gram a watt) and while pics of her are all over this site I am including them here for those of you that have never seen her.
During all of this experimenting I figured things out and in the process broke several known myths, I decided to share this info but realized that most folks would not get it. I came up with a plan to create a little game in order to share the info and several members played and helped create a very truthful, imformative thread that has helped many new growers. It worked and as a result every one that participated got thier grow on and started having sucess in thier gardens.
A new member recently followed the whole thing and told me it took him 2 and half days to read it all. I realized that this would limit how many people would actually take the time to do this and decided to post this thread giving YOU new growers the final reward (from the game) so you could decide for yourself whether or not you wanted to take the time to follow the game/class and get the info for yourselves ( the game itself happens in the first 40 pages of my NooB Advice thread, but has links to other threads, know that the answers are all in the thread so you don’t really have to follow the links unless you want to. But I do advise it.)
Here is the final reward summary of the class quoted from page 36 of the thread,
All of you that have played my little game have earned this. You have done the research and contributed to the thread in a very positive way. I have found that things click best and we tend to remember better when we do our own research and put things together on our own. I feel that to be a good teacher you have to know how to lead a horse to water so to speak.
.
Thank You for playing my little game and thank you for helping to make this thread work!
.
.
Now let me tell you a story, all the books I have read start out (or contain) a history of the plant we love. Some add in some of the myths, my fav is the notion that MJ is an alien plant that traveled here long ago and has been helping humans out in various ways. I want to believe this one because of all the good and positive things that are known to come from this plant. No, I’m not gonna dwell on history or notions. Let’s just say I started this like all the others and move on.
.
There are many myths that just keep on surviving, simply because no one knows better. I suspect that it’s like the game where you whisper something in another persons ear and pass it to the next person, the more people in the circle the more the info gets distorted. It’s a fun exercise to try. Could also be that black market commercial growers have distorted the facts over the years to cut down on competition? Does not really matter where they came from, they exist, and there is some truth in all of them.
.
But lets get to the prize, for starters then we’ll discuss some other things. With your help I have managed to include all of the facts (mantras) that allowed me to see what was happening. Plus I added a few extra clues to help fire up your thinking processes, get the juices flowing as it were. I know that if you are serious that you read my grow journal and saw what happened when I did my first flush and then fed her the so called super tonic ( I will continue that experiment and it will be detailed in my journal).
.
Here is what actually happened, I simply made it rain.
.
Ponder on that and if your mind does not click things into place and start running a million miles a second you need to go read some more. Joking, What we hear called the flush is very simply what mother nature does when it rains. Now as I continue this story I am going to put my thoughts into laymens terms so that everybody gets what I am trying to say. I am not a botanist and while I know some of the big words and what they mean I do not pretend to fully understand all of this plants functions. That being said. The one missing third of the flush question in the thread was the fact that buds tend to fatten up towards the end (last 2 weeks) DURING THE FLUSH. Of course in most grows she dies eating herself, because folks tend to let her due to some taste, smell, whatever thing???
.
Remember earlier in the thread when we were talking about watering, someone quoted Uncle Ben and said water till you get PLENTY OF RUNOFF, sounds like a flush to me? not a drip, not a tray full, but PLENTY. You will get what looks like over watering and that can be scary the first time, as I detailed in my journal it was cool to see her curl up and droop. In my way of thinking this is when they actually sleep (mother natures way) cause we know they are doing things in the dark period. But I must admit that my research said they sleep in the dark period?
.
Now for me I think they are sleeping because during a rain there is most usually no sun (for awhile) and the PH of rain is 5.6 so no nute uptake, and the roots are soaked in water so there is no oxygen. Damn she is basically drowning. But I believe she shuts down and waits for the sun to come out, at which point she goes into overdrive to WICK the water out of the ground ( another word you hear UB use a lot) I believe that what I saw happen with that growth spurt (I have proved it with subsequent waterings) was being able to read when she wants water and when she wants food.
.
Let me draw the picture for you, mother natures way is to rain, then all the plants transpire the water back into the air and it rains again. Knowing this the best advice I could give a Noob when it comes to watering is to follow the instructions on your shampoo bottle,Rinse & Repeat. Remember I was watering normally and it was taking 5 to 7 days before she needed water again but after the flush (rain) she wanted water after 2 and 1/2 days, this was when I gave her the super tonic. So basically I fed her. I see this as the acidic nature of rain is to release nutes from the soil so that once the water is wicked off the nutes will be available for the plant and the circle of life continues. So to tell you how to read your plants is simple after she has had a good meal, she wants it to rain again and after she has wicked off the water she wants food. WARNING if you do this in veg you will have trees! Remember that as you plan your grow to fit your garden.
.
It really is that simple and because you are both God and Mother Nature in your garden you can make it rain when ever you want. And because it takes time for the rain to activate the nutes in soil putting some in there after the wicking process makes them imediately avaiable. Please note that I did not PH my water down to 5.6 (but I am gonna experiment with it) when I flushed which I feel makes the nutes we feed her available even faster as we do not have to wait for the PH to balance itself as much.
.
Now lets get to some truths from the forum, everyone says start feeding at 1/4 strength, this makes total sense when you realize how we are now feeding her. If we gave her full strength every 3 or 4 days we would burn/kill her.
.
Put your finger in to test the moisture of the soil, this makes sense to understand when she has actually wicked most of the rain water out of the soil. Remember we do not want it to dry out we want to add our nutes right before she runs out of water to wick and while she is in overdrive to do so. Remember also that the next day after I fed her she was dry again and wanted more water. Hell I had not yet figured it out so I watered her as usual and she settled back into that lets go slow thing again. It was all of the total picture and having the mantras in my head that made it click for me.
.
Now that you understand how to water and feed properly, let’s talk about soil. Obviously when starting out with seedlings/clones you need to nurture them and a good soil is an important part of this. Regardless of what you think or have read about it being possible to grow in Miracle Grow, stay away from it! It most usually comes in with a low PH (around 5.5) has bugs in it and is bad for our plants. I honestly believe they do this on purpose to cause harm to us MJ growers but that is just my opinion. That being said any good quality light soil (not hot with nutes) will do, as you know I like Happy Frogs (which would be considered a medium nute soil). You should start out in 6" Coir pots (available at nurseries) because they will get you thru the nurturing phase and transplanting up is as easy as planting the coir pot into a bigger pot. The proper way to do this is to fill a big bowl or pan or bucket (you get the idea) with water and submerge the Coir pot in it until it is soaked (no bubbles comming out) plant it in the bigger pot. No problems, no worries, no messing with roots. Do NOT water her after you put her in the big pot. Here is what happens, by submerging her in water, you put her to sleep. When she wakes up she will transpire (wick) the water out (from being submerged) and then will go into the new soil (in the bigger pot) looking for nutes. This method assures that there absolutely no stress from the transplanting.
.
NOTE; You can do all of your control stuff during this nurturing/veg stage things like topping, LST or supercropping (totally your choice, I suggest you experiment with all of them and learn what you like best). You can do the make it rain thing to get bigger plants or you water them the slow way (to keep em small), simply remembering not to over or under water (I have already told you how to figure this out)
.
Ok so now let’s talk about the soil in the big pot. It does not have to be fancy and does not have to be organic, does not have to have nutes in it. WHY? because we are making it rain and suplementing nutes. This is why things like soiless mediums work. What we want now is called a Potting Mix (as opposed to potting soil), this puts us in complete control with regard to nutes and feeding and allows us to totally dial in how many nutes our plant (strain) can take without burn. Go to your local nursery and ask them to reccommend a good potting mix, and just get it. Now into this potting mix we want to add 1 cup (about a handful) of Sphagnum Moss and 1 tablespoon of Dolomite Lime this per gallon of soil (gonna refer to the potting mix as soil from now on, easier to type). WHY? because the Moss retains water and has a PH of 3.5, The Dolomite contains CAL/MAG (which MJ loves)and buffers the PH back into an acceptable range with each watering. I work and am gone everyday for 9 to 10 hours, the last thing I want is for my plant to wick out all of her water while I’m gone, so water retention is important to me. This is also why I put an inch of perlite in the bottom of my big pot. If your soil does not have perlite in it add some ( 1 cup per gallon of soil) when you mix it up. Because you want GOOD DRAINAGE for when you make it rain.
.
Now let’s talk about Nutes, You only NEED one or two (you should get both and alternate them) First is DynaGro ($12.99)as it contains ALL of the necessary nutes that a plant NEEDS in just one feeding. Second is Jack’s Classic ($4.99) as it is stronger in N-P-K values and has other needed supplements. Also add 1 teaspoon to 1 tablespoon of GRANDMAS UNSULFERED MOLASSES (as long as unsulfered other brands will work, but I like Grandmas)to 1 gallon of water as it contains Carbs and Sugars (has other good nutes as well) that aid in growth, MJ loves it. When you feed Nutes you just need enough runoff to know that the pot is now full of nutes (no point in wasting them). As to measuring, start out at 1/4 strength per the instructions on the package and slowly (with each feeding) work your way up until you notice ANY sign of nute burn. At the VERY FIRST SIGN of nute burn you have discovered what your plant can eat in a single feeding without problems GO BACK A STEP (I would go back 2 steps) and now you have your proper feeding mix for your plant (strain). I am including the word strain where it is important as no two strains will respond the same, why you should only grow one strain at a time and learn it. And by learn it I mean you should be keeping notes as to what works best with each strain so you can consult them in future grows. NOTE: By slowly working your way up I do not mean going from 1/4 to 1/2 more like 1/16 to 1/8 increments to get there, after all we do not want to overburn them! P.S. YES Nutes are this simple.
.
I want to spend just a moment on organic, if you somehow feel you must go organic then I’m not sure how it will work out for ya? In my opinion organic is a thing created by high commerce much similar to the fancy MJ nutes. I don’t knock it cause it creates jobs for folks but also I don’t do it. I honestly believe that if you sit in a blind taste test with properly grown, properly cured MJ, that you could not tell which one was organic and which was not. Not only myself but Uncle Ben agrees with this as well and several books I have agree it does not matter. Both DynaGro and Jack’s are high quality nutes made from the best chemicals with the best processes available. Not like MG which is crap. And I just followed a grow journal where the member switched to Jack’s and said there was hands down no competition from thier previous grow, Jack’s was the shit.
.
Humidity and Temp as we discovered in the class/game, are very important as is the heat index, as the proper combination helps with fast transpiration (wicking). I will briefly touch on the humidity for veggin should be 50 to 60%, think april showers bring may flowers. For Clones & seedlings should be 70 to 80% cause they need more moisture in the air till good roots develope and for flowering should be in the low 30’s to prevent mold as for temp MJ is temp tolorant from 50F to 90F but what you want during flower is a fall like temp with a heat index that does not exceed 78F (remember mine was 76.5) this is why I gave you the link to the heat index calculator. You want your humidity and temp combos to have a heat index just a few points above your actual temp to achieve fast easy (no stress to plant) transpiration. doing this will create the perfect enviroment for your girls and they will love you for it, by giving you big buds.
.
Circulation, is also important as we discussed in class and can assist in maintaining your humidity and temp. no need to go into detail here as there were several good methods for measuring it in the thread. Also no need to go into CO2 here we covered that as well, just know that if you were to go commercial, that the addition of CO2 allows you to raise all the numbers and make things happen faster. Also and this is very important, your plants want space between them. I see so many growers cramming plants into thier garden which goes against ALL known gardening facts. Your pots should have at least a foot between them and a foot and a half is better. This aids in circulation and light penetration and gives your plant the space it NEEDS to flourish.
.
Keepin em green, is not only a mantra, but a way of growing. It allows you to harvest the good (big) tops and then lower the lights and finish the lower buds (increasing your yields) and allows you to put her back in veg and go again with the same plant, just remember to leave the fan leaves on when you harvest the lower buds. It also allows you to flower longer and get those those huge donkey dick buds everybody drools over. as long as your plant is healthy and happy there is no reason for her to die. The saying “Patience is a virtue” is completely true. So many new growers are in such a hurry to harvest that they chop early. The reality is you should chop when the buds are ripe (and huge) and the breeders estimations of grow times are crap, the plant is done when it is done. My advice to you is this, grow more than one plant and when you think it might be done, only harvest one of them so you have some smoke and let the others go to see what they do, My other mantra do it, watch em and learn. This way you will learn what ripe is for you and the for you part is all that matters it’s your smoke/medicine.
.
Water, There are so many theories on what kind of water to use. As you know I run regular tap water thru a brita filter I do this because it comes out 6.8 ph and filters out the crap that MIGHT be there (I’m not gonna pay to have it tested). I DO NOT let it set out to vape chlorine and I do not let it reach room temp. Let me share some more common sense with ya. All over the USA folks are watering thier lawns, trees, shrubs, bushes and flowers with city water from a hose or sprinkler system. NONE of them are dying, there are lush, green, pretty yards all over the place, so I’m pretty sure tap water is ok though it is true that there are areas that commonly have hard water (discussed in the Insiders Guide book, no reason to repeat, you should have purchased that book). Also I have, many times stood outside while it was raining and it is always COLD, plus I have experimented with it. Silly idea I had about how the cold would shock the plant and how the ground is warm from the sun, so I started with room temp water and gradually made it colder to see what would happen. Guess what it slowed transpiration down and she did not droop. So when you make it rain just use regular cold tap water, filter it, if you like and know that her drooping is a good thing!
.
Lights, We pretty much covered this in class, you know that I prefer CMH. WHY? Closest spectrum to the sun there is from ANY bulb. Less heat to deal with. Can be used for both veg & flower (since it has both spectrums) and has UVB to make more resin. Only available up to 400 watt and requires an older type magnetic ballast is why commercial growers don’t like em. But for personal medical grows this light is the bomb, period! I have proven you can grow big buds with a small light, that was my intent in doing so (and let’s be honest it’s why your here cause it got your attention) I have shown you that not everything you read/hear about lights is true.
.
Summary, I have given you all the info I know, (and broken many of the myths) I have shown you with pics that I am not full of crap, don’t know what I’m talking about Blah Blah Blah. I have proven that the Sum of ALL parts is what makes your grow successful by growing Matilda under one cfl (light is just one of the parts , that is most misunderstood) And Lastly I have had a BLAST doing it! Now get your grow on and good luck.
I know this is a long winded thread and I thank you for taking the time to read it, I hope that you found enough info here to make you want to read the thread to fill in the banks, knowing that it will take time but in the end be very worthwhile in helping you to fully understand things. After the class the thread goes on answering question and discussing other things, reading all of it will also be beneficial.
Here are the pics of Matilda,Enjoy
Keep Em Green and Happy Growing to All

You can still use the weighing technique, it you so wish. Simply fill one of your 3gal. pots with your soil medium and weigh it dry, doesn’t have to have a plant in it of course. Than after watering one of your other pots, weigh that one and find the middle , and remember ( pencil and paper helps:wink:) how long it took to get to that weight. I like this system, its easy and seems a bit more accurate than the “finger” method.

That looks nice to me bro I think you’ll be fine
Give it a day see what happens your in a big pot now
so try this put a bottle over the top of it maybe a 2 liter cut bottom off lol
Then pour water over that and get soil moist around her
Then let her dry out and wateragain same way or around outside of pot not around root this way the roots grow out looking for water
