ok then I guess ill go ahead and put the rest of that in there its a 1 lb. bag so that's about 1 cup per 2 cu. ft. its going to fall a short of your 20% I added this to approx. 6 cu ft of soil its what I got its going to be better than none in there for sure I plan on keeping this soil for the next grow thanks for the info con!If you have good biology about 4-6 weeks, but it’ll last at least 6-7 cycles as far as Ca/Mg are concerned if you established good base saturation from the get-go. I usually add as much as 20% of total volume when I cook new soil.
