I bought the Medical Grower's Bible by Jorge Cervantes and I love it. I love to have it around all the time. I never have to worry about a disfunctional computer, internet, or web site. I don't know how many times I got a "Server is too full, try again later". The facts are all cited(Told where the info is coming from) and accurate. I'm also guilty of thinking I knew the answer when I didn't, and then was corrected on this site. You might ask a question, and your first response could be from a know it all that don't know jack. I will take something for free if it's not good. I think for all the information in that book, it's worth the $20 for a fresh copy. Especially for someone with little to no knowlege of growing. It has ALL the basics of the common ways to grow. Before I got my first book I didn't even know that there were male and female plants. My first grow was ugly, and didn't get me anything more than the mids for sale in the ghetto. But now I can grow you a Skunk1 bud that will make wonder if I added something to it to make it taste so sweet. And then wonder how you got so high lol.
