What are you saying? I've never grown OG Kush, but I am currently growing a hybrid of it crossed with a Cherry strain(Cherry Kush). Not sure which. The hybrid is a very potent, pleasant high. It was every bit as good as Girl Scout Cookie and White Russian, last year.
I learned a bunch with Cervantes when I was first starting. Breaks it down in sections and has nice pictures so you can tell exactly what he's talking about. Very informative.
Thanks guys. I just watched his videos on YouTube the last couple days and am going to get his books now. I like learning from this forum but it's also nice to have a published source
