It's been a pleasure following your thread. I joined the community to find out about leds and just like some of our colleagues here, i think you've made me a believer. Just like everyone else, heat has always been an issue for me and have always wanted a realistic alternative that wouldn't leave me with wispy fluffy buds. I think I'm going to order my first set asap. I want to start out small with a small stealth grow is a 2x3 space. (I'll have the opportunity to expand to a 4x8 space in a couple months.) For a 2x3 flowering room, do you think a 90w 5 band will be enough? Also, what growing medium are you using? I think I'm going to be using clay grow rocks and vermiculite, hand watered for now. Any advice is most appreciated. -DF
