Nice, I might as well primer it and paint it. I think I am still going to mylar the ceiling though. So in a room that is 4 x 8 and with only 3 plants, would 4 - 48" be sufficient or should I look at 6?

Also, my basement is closer to 68-70, is there a good way to add heat if I need to. I assume my tubes won't heat up the room much at all
