I'm currently getting ready for my next grow and I'm having some difficulty choosing which brand of potting soil I want to use for my base soil. I do not want to use Roots Organic or FFOF because all I've read about this brand is GNATS. Man, I've had enough gnats, I wanna do everything I can to avoid having to string fly paper all over my room. I've been thinking about using Happy Frog but I'm not sure HF has coco and myz in it. So I was thinking Happy Frog + Promix. Not sure yet, so looking for some feedback. What do you use for your base soil when mixing super soil?
