Promix is also inert(no nutrient value of its own). Its also very cheap and high quality. You can get a compressed cube of it from the higher end gardening stores for like 20 bucks and it is the equivalent of like 4 bags of uncompressed soil. I like it because It gives me complete control over the nutrient levels at all times... the only nutreints they get are the ones i feed them. But promix does have the mycorezea (spelling?) that help break down the nutrients to a form the plant can use. I have a buddy who always grows the same strain in the same conditions who did an experiment using different soil mixed with 10% perlite. He has used foxfarm, happy frog, MG moisture control, Promix. It wasn't a perfect experiment because promix was the only one without fertilizer. And he saids the MG works well but swears by the Promix. 25 dollars spent on soil per 1000w, comes in one giant cube, and holds water (imo) just as well as the moisture control. He'd just give them 1 liter per 5gal every two days and the soil stayed perfect. And alot of people don't like growing with peat moss beacuase they say its acidic and will cause problems but promix is pH adjusted and assuming your using a decent nutrient line (GH flora series 3part) and your water is clean you'll never have a problem.
