I’m Rich Hamilton.  The author of The Growers Guide books, I’ve done everything from running my own 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’am the director and owner of the publishing house Machiavellian Media, where we produce the Growers Guide series.

Additionally, I currently write for three international hydroponic magazines, and I’m a freelance consultant for hydroponics companies around the world as and when they need me.
