Do you know a good place for me to read about it so that I can understand it more.
Absolutely! The best book on Hydroponics I've ever read in my life is:
Hydroponic Food Production: A Definitive Guidebook of Soilless Food-Growing Methods, 6th Ed.
Howard M. Resh This link also has many other hydroponic books, but I would suggest you read Dr. Resh's book first.
I haven't read the most recent couple of versions, and he added a lot of new information about the latest growing techniques in them, from what I hear.
I read the first two versions, (I'm an old guy...), and I think edition 4 or 5.
This book is considered the "Bible of Hydroponics" by many, including myself. The history, and many hundreds of examples are discussed and examined. The exact methods and why they're used.
If you buy no other books about Hydroponics, you HAVE to at least read this one. Any library can get it for you on loan as well. Just ask them about their "Intra-Library loan system" and give them the ISBN for this version, (9780880072229).
After you've read it from cover to cover, you'll have a wealth of information about Hydroponics that you never knew existed. When you have finished it, come back and ask me about what parts are different for growing a very fast growing plant such as Marijuana. It's requirements are unique when using indoors hydro. Everything is on "Fast Forward", (that's why my one hour on two off pump cycle).
I've been growing Marijuana for more than 40 years. I've been doing so using Hydroponics for more than 25 years. I wish I had the talent for writing a book and could transpose all I've learned into an instructional guide, but alas, I'm way too busy having a life.
Good luck man!
