nice plants, they are sure to produce lots of good herb. you said you were using a nutrients called "petersons" or something like that. I have had trouble locating good nutes down here, but have recently been using Evergreen 20-20-20 plus fish emulsion in veg, and more evergreen flower nutes, with some organic molasses aded. results are pretty good. do you throw right in the topsoil or do you add anything to it?
