Hi, I really like smoking, but I get tired of paying for it! My buddy and I decided we're going to start growing. He's got a good sized metal shed that we are planning on insulating and hanging some flourescents. I'm not exactly sure how everything is going to work out, but we want to do it cheap. I'm a noob to this stuff so bear with me! I'm looking for advice, one thing I have to ask about is the male/female thing. How do you tell the difference? And can 1 male screw up several females? Thanks in advance!
