Hi, I know a lot of you are good with gardening and I need your help. I am planning to grow some sunflowers in my apartment. I have done a lot of searching but seems like everyone is saying something different. First of all, what kind of lighting do I need? Will a 30W spiral CF in this be sufficient? Second, what kind of soil should I use? I went to home depot today and I was confused by all those different selections. Thanks in advance!
