I hate to sound like such a tight ass over dirt but Fox Farm isn't getten any cheaper.. I will be growing single auto's in 5 gallon buckets - my soil mix is FFOF & a small gritt petrolite - I will use the standard 3 part FF ferts. I'd like to sift and dry the soil after harvest & store it for another grow with maby some additions if needed of should this go in the garden ?
