I've been doing some hydroponics lately and I've noticed I don't have much insight about how plants really work under the hood, I would like to have the full picture and understand more about it.
My primary interest is to apply botany knowledge on my hydroponics projects, not to get a job/degree. But, I do understand that studying among my peers is a rich experience, reason why I'm considering this kind of training instead of just grabbing a book.
However, I'm not sure how extensive is the study of botany, if I need a degree in X before starting it, etc.
Also a good book is welcome.
