I've been growing outdoors for about 10 yrs. I kept it simple with nature really doing most of the work. The only nutrients I used was fish emulsion. I would prune a bit and also remove any male plants. I had some pretty good crops and I only used whatever seeds I had kicking around.I decided to try indoor growing. Started with 2 small plastic tubs. As plants grew so did my enthusiasm. I've learned a lot and have now designed and built a grow room which I upgrade as I learn thru trial and error. I'm hooked on this now. I've always liked gardening but growing cannabis physiologically is really intriguing and challenging. Great Hobby. I love reading people's grow experiences as well as advice. I welcome all input.
