too expensive vs. too expensive. a 2.8 cu.ft. bag of neutral grower's mix is 15 USD at a garden center. if you are going to spend money on fancy nutes, you don't need a hot soil. i use peat, perlite, and poop as a base. costs about 4 USD a cu.ft.
I want to sail away to a distant shore..........an' live like an ape man.
@Malignant, what type of yield do you typically (rough average) see with a 7 gallon container?
Yeah Mal! I like to do big girls too! Fabric pots for the win! You must have great light intensity in there. Is the gravity a must, that company has mucho secret/undisclosed ingredient issues no? CO2 usually gets em dense dense IMO.
