I got a little ahead of myself and got a 10000k 400watt mh. The color is similar to what I got going here and it's been working quite well. The thing gives off a lot of UV, I guess I'll run it at night and only see my plants during the dark cycle. At least I'll be able to grow tomatoes this way. Maybe I should do one for my vision and put it aside and call it a $40 mistake. Thoughts?
