Help with tweaking Super Soil ingredient ratios

Happy Holidays to All:
I have a left over 1.5 cu/ft sack of FFOF and would like to use it as base
for 4 cu/ft super soil. I’ve found most recipes have similar ingredients, it’s
the ratios I’m stuck on.
I’ll be using 6)10 gallon fabric pots, (8 cu/ft) and if I read right, fill 1/2 SS
& 1/2 quality potting soil. Thanks

Do you have a list of ingredients in ratios as well?
Example bone meal, blood meal etc…

you can add just about anything you want,but keep in mind to be effective you have to get a good cook on the soil .
with one bag of ocean i wouldnt go hard on ingrediants,the ocean forest is good for a 30 day veg without any nutrients in my experience,now the whole idea behind super soil is to put in the bottom of your pots for the flower stage,if you start with ocean say in solo cup,uppot to a 1gal then by the time you go to final pot of say 3gal your soil would then be cooked enought to give it the boast it strives in transition and flower,then that soil on bottom will bang the buds and pretty much be a water only thing if you dig what im saying.
best thing to do is look at what minerals you can afford and want in your mix and go from there,ask yourself htis right off and it will answer your question,do you want to reuse this soil for future grows,if the answer is yes then look into slow release and medium release minerals,all fast release minerals are avialble like blood bone and also leach out quick threw watering,so your looking for med and slow release minerals for your super soil

This is the last recipe I followed. I have since starting adding Neem cake and Karanja. Also trying lava rock and pumice instead of perlite. It’s a work in progress.

Supersoil v.2

1/4 Recipe

2 large bags of a high-quality organic potting soil with coco fiber and mycorrhizae (i.e., your base soil)

1 cu ft. organic worm castings

1.25lbs or 20 ounces steamed bone meal

1.25lbs or 20 ounces bloom bat guano

1.25lbs or 20 ounces blood meal

12 ounces rock phosphate

8 ounces kelp meal

8 ounces alfalfa meal

4 tablespoons Epsom Salts

2 table spoon feather meal

1/8 cup or 2 tablespoons sweet lime (dolomite)

1/8 cup or 2 tablespoons azomite (trace elements)

1 tablespoon insect frass

1 tablespoon powdered humic acid

1 tablespoon powdered fulvic acid

1 tablespoon recharge

1 teaspoon mychorizae powder

10-32 oz cups coarse perlite


I just read up on BioChar, (charcoal) it seems that’s pretty beneficial, I would add that in the recipe if you can. @AAA
Those ratios seem pretty decent, I wouldn’t know the first place to find insect frass. They sell that in a bag? lol. If only people knew what that was, they might get grossed out.
I figure worm castings would be enough.


@Covertgrower funny, this last batch I added it.

I’m actually transitioning from this supersoil recipe to a “Coots” living soil mix to start no till gardening. Infant stages but I will be posting soon enough.

You can buy insect frass. I’m using as a foliar spray outdoors to keep budrot and WPM at bay. That was a tip from @Mrcrabs!


Outdoors I might use a foliage application, but indoors, I don’t spray anything on the leaves unless I need to.
I’ll be purchasing a super soil today and growing a plant in it to see how it goes.
I figure if nothing else, it’ll assist me in not feeding as soon. I have a quite a bit of light in my tent. @AAA

Thank You. I’m trying to build soil using locally bought ingredients, and leave as little carbon footprint as possible. off subject here… I’ve been a veg/herb organic grower for decades, and never use bug sprays. Try growing marigolds, or garlic close to your plants, beneficial insects (ladybugs, and mantises) can be bought cheaply, or free if you know where they over winter. As odd as this sounds, a little adversity is actually good for plants…toughens em up.


Doesn’t sound odd at all
