I’m Rich Hamilton. The author of The Growers Guide books, I’ve done everything from running a hydroponics shop to working for large distributors, designing new products for the hydroponics market as well as managing sales. I have released 4 grow books to date. I'm the director and owner of the publishing house Machiavellian Media, where we produce the Growers Guide series. Additionally, I currently write for international hydroponic magazines, and I’m a freelance consultant for hydroponics companies around the world as and when they need me.
