Alright, I'm a n00b with this and have read too many guides, and I'm lost. I need to grow cause I cant afford buying all the time, crazy right? Well, I need help. I've got seeds, I just need to know the other stuff. I only have 3' wide by 3' deep by 3' high..not much room. A. What material should I build out of, B. What lights should I use, C. any other information i need to know. Thanks!
