Can you help me mix at proper ratio?

I'd like mix at a proper ratio and allow it to "cook" for a month. Then I'll add clones, veg for a couple weeks before throwing them in 12/12.

2 bags of Fox Farm soil (around 11 gallons a piece)
15 pound bag of worm casting
Indonesian bat guano (.5-13-.2)
Small bag of Magnesium sulfate
Dolomite lime
Perlite

If there's anything else I should add, please tell me and how much.

I need enough mix for ten 2 gallon containers.

The strain is blue og x gdp.

Thanks.

If you are not mixing wet ingredients why do you think it needs to "cook"?

Hmmmm. Easy and cheap way - KISS

This is for close to 2.75 c/ft......do this twice and combine them for the "cook" - easier to do it twice and combine then turn 5 + c/ft at once

5 gal FF Soil
3 gal EWC
6 gal coarse Perlite
3 gal composted steer/cow manure
1 small Coco fiber brick (moisture retainer)

FORGET the Mg Sulfate! (Dolo has plenty of Mg! You won't need more!)

1.25 cups Dolo
4 cups Garden Gypsum
1 cup Azomite
2 cups FF Peace Of Mind Fruit And Flower

I would mix these and water with FUL-HUMIX mixed in the water and cook for 2 - 4 weeks or until there is nothing but a deep rich humus or soil smell when sniffed.

This mix will carry you through a short veg run with water only! No pHing needed....

Good luck!
