So I'm new to this site and the first thing I wanted to ask was for some advice on my new grow box I was planning to make. I'v got an old amplifier that is hollow from the back side, so I was planning on just taking some wood and hinges and making a door on the back and taking a small light and putting it in on the top. My main question is if I should use a fan or not, I'v grown before but never on such a small scale so I'm just a bit worried about if the plants will receive proper air or not and I'm also a bit concerned about the plant getting into the fan as the amp itself Isn't that big. Any advice/answers to my question would be appreciated.Thanks ^_^
