Soil...what to use and why


#1
My 1st grow I used a mix of box store growing soil and did fine....but i would like to try FF Happy Frog or the Ocean Forest mix but heard it was to hot for seedlings....I grow autos under LED and wanted a seed to finish soil so there's no need for transplant etc.....thanks everyone


#2

@Ky2high I know FFOF is hot but I want to say FFHF is not. @bob31?


#3

Look into the promix bx or hp lines
I like since it has no nutrients in the medium so i can control what the plants receive and when
Its a peat based medium that drains well and Cannabis grows extremely well in it
Its fairly inexpensive as well
You can use it start tonfinish which is a plus since you dont need to store different soil types
You are correct @Tylan


#4

I was thinking the same and I would think the HF would be to start them then transplant to OF but iam not wanting to transplant. So iam not sure. I’ve seen people use OF but use a organic mix or HF in the middle so plant grows into it but again iam not sure…thx for helping etc


#5

@Ky2high Some people put top later HF and bottom layer OF so when the roots reach that far down they get the nutrients they need.

@Countryboyjvd1971 is right about promix. I switched after I used OF. I had zero complaints with OF except I am pretty sure I had some soil gnats that came with it. HF doesn’t appear to have that problem. Something to consider.

You can use HF the whole grow you just will have to keep an eye on your ppm earlier than usual than with using the OF.

@Ky2high

I fixed your link for your picture and it shows up now.

Soil
This is what I use from start to finish. How much to use all depends on how many plants and how big your pots are.
Also, all I had to do using this soil was water my plants every 3rd day

Soil LESS Mix

Mixing ammounts will veary dependeds on how much you make. read instructions on each package for amounts.

1.) Pro Mix BX

Then add-----

2.) ( Mexican Bat Guano )

(10-2-1) This type of guano is very high nitrogen. This makes it perfect for the vegetative stages of growth. Even when the plant is young it can be fed a dilute mixture if the soil happens to contain very little nutrients. This type of guano can be used throughout the vegetative stage of growth.

( PLEASE NOTE )

( Jamaican Bat Guano (1-10-0.2) This type of bat guano is high in phosphorus. It is perfect for the early-mid flowering cycle once females are well established. )

3.) WORM CASTINGS

(because this stuff is so nutritious, the more the better).

Worm poop is gardening gold. Properly known as “worm casts”, what worms leave behind is actually
vital to the soil food web and is one of the key substances to maintaining healthy, nutrient-dense
soil for your plants. To quote from Sustainable World Radio:\8–

“Research has shown that fresh earthworm casts are five times richer in available nitrogen,
seven times richer in available phosphates, and 11 times richer in available potash than the
surrounding upper six inches of soil. […]

Plant roots often seek out available earthworm casts. They follow the worm Burroughs and feed
on the nutrients in the available vicinity even if it means that the roots have to grow upward.”

While growers often spend a significant chunk of change on fertilizers throughout the grow cycle,
adding worm castings to your soil inundates them with the vital, natural nutrients they most desire.

4.) BONE MEAL

This additive is a nice way to get some additional phosphorous and calcium to your plants. An abundance of phosphorus
is especially important once your plant has reached flowering phase. To again draw from Gardening Know How:

“Using bone meal will help your flowering plants, like roses or bulbs, grow bigger and more plentiful flowers.”

As a flowering herb, the added phosphorus from bone meal helps your plant produce buds that are nice and big.

5.) BLOOD MEAL

Blood meal is yet another source of nitrogen. It’s also not vegan/vegetarian-friendly.
Blood meal is made from the dried blood of slaughtered animals, most predominantly cows.
Though the idea behind the fertilizer is a little unpleasant, its well-known natural gardening product.
Because it’s so nitrogen lush, it will help produce extensive growth during the vegetative phase.

6.) FISH MEAL

7.) Kelp and/or humid acid

Marijuana growers are very smart gardeners. There are a lot of things that growers do to increase
their yields that actually helping to build healthy soil microbiology. Adding kelp meal and humic
acids are some of these tasks. Both of these natural products are fungal foods. The interaction
between your plants roots and soil fungus helps the plant produce the nutrients it needs to thrive.

Kelp also adds a significant amount of potassium and copper to your soil mix.

8.) Epsom salt

A lot of people use Epsom salt to increase magnesium in their soil. As mentioned earlier,
you want to be careful not to add too much. You don’t want to over do it with the magnesium.
However, if your plant is showing signs of a magnesium deficiency, this is a very quick and
easy way to add some back in. Magnesium iscrucial to the absorption of other key nutrients,
like nitrogen and phosphorous.

All about microbes

Subcool’s soil mixture is definitely a good one. As is probably obvious by the various additives
in this recipe, this soil is extremely nutrient-rich. It’s chuck full of natural fertilizers and
makes it easy on the plant to have its favorite nutrients right at its root tips, so to speak.
Many of the extra or leftover additives can then be diluted with water and sprayed on during
the grow cycle as fertilizer.

If there’s one downfall to this recipe, it’s that it relies heavily on organic additives over
encouraging microorganism growth. In a plant’s natural environment, they get vital nutrients
from synergistic interactions between the plant and other organisms in its ecosystem. Plants
photosynthesize sunlight into sugars, and these sugars are in turn secreted by the roots. This
is a much more consciousprocess than commonly believed.

A plant can make an extremely wide variety of sugars and secrete them to attract specific types
of bacteria and microorganisms to its roots. These bacteria then eat these sugars, called exudates.
Through the bacterial metabolic process, essential nutrients like nitrogen are created for the plant
to use. Yet, nitrogen isn’t the only nutrient created through this process. This is how much-needed
vitamins and trace minerals make it into your plant.

9.) Dolomite lime

Recommended amount: 1 cup

Dolomite lime adds calcium and magnesium to your soil. Like rock phosphate, dolomite is also
a kind of mineral rock. It’s used to counteract mineral leaching. It also helps keep the
soil from becoming too acidic. Be careful not to add too much, though. It has high calcium
to magnesium ratio, and you may risk adding too much magnesium to your plants.

Azomite (trace elements)

Azomite is a brand of trace minerals. It’s mined from volcanic rock and contains over
70 minerals and trace elements. This particular brand is mined in Utah and is used to
re-mineralize soil. The product contains everything from gold, silver, and selenium
to potassium, choline, copper and calcium. Adding a few trace elements into your
increases the diversity of nutrients available to your plantss.

10.)

Marijuana growers are very smart gardeners. There are a lot of things that growers do to increase
their yields that actually helping to build healthy soil microbiology. Adding kelp meal and humic
acids are some of these tasks. Both of these natural products are fungal foods. The interaction

Kelp also adds a significant amount of potassium and copper to your soil mix.

@Tylan FFHF has nutrients but not as hot as FFOF. I don’t recommend FFOF for new growers.

If you go with the promix, you will need nutrients as soon as the dicotyledons die off.


#8

Thanks @bob31!


#9

I use a 50/50 mix of happy frog and ocean forest with great results!


#10

Do you still use fox farm nutrients and if so at what ratio…


#11

In the past I mixed Happy Frog and ocean Forest one bag to one bag. It ends up being slightly in favor of Happy Frog but I’ve had good results. Good luck and enjoy


#12

@Ky2high you can go to fox farms website and download the chart. Sorry I don’t have it with me at the time

That’s the chart I follow too. Nice addition @Bshmstr
