Thanks to everyone! Amazing information about where I can find information, I am going a little bit to the science side, first I fucking love this plant, and second I wanna know every single detail about her. :-)
Dr. Bruce Bugbee is amazing, I think I have watched around 20 videos from him on youtube last two days, high-level information for free, so I am really thinking about getting his online course, but 1400 dollars right now is difficult.
So I will get the book as the best answer, because I was looking for good books as well, but didn't have a clue about which one chooses.
Again, thanks everyone, happy growth for all of us.
