Glad, then you're setting yourself up to go back to hydro. You've been doing hydro for years; what are the chances this first soil grow will have more yield than your experienced hydro grows.
The problem with all of this is that there isn't a serious horticulturist that would ever do what the Rev recommends. And let's face it, when you have a magazine, you need advertisers, so if you write a book, you had better include all your best advertisers.
Biologically, horticulturally, scientifically, this fails. Largely stoner science which is SOOOOO easy to propagate because stoners love an idol. Could be Ed, could be Subcool, could be the Rev. It's very easy to sell stoners the farm. Sad, because paradoxically, stoners are generally broke and spending money they don't have. It's really stoner exploitation.
