Well, forgot some info. They are LED 's I got from ebay. I soldered them myself. I have run them for 3 months with nothing in the room. Just to see what the power consumption would be. Before with the other lights my electric bill was $540 a month. With my whole room set up it is now at $287, which is $40 more than what I use with no room at all. No fans. Did have to go buy a little space heater since the led give no heat at all. Lights are all the way up since the plants are getting used to the light. Yup, just red and blue for flowering. 75% red to 25% blue, and for veg just straight blue. Out of the 70+ panels I made, this is what I found is best since it produced the best results. In veg I get 1 1/4 inch growth a day, easily. Most often if I put the light to close and forget to check on them for a couple days I find they are touching the light. All are 3 watt, found that 5 watt was over kill. In the flowering room I have a total of 5k in watt from led. Complete overkill, buy they love it. I tried the other colors like the amber and yellow and whites. Found that they didn't do as good. If you have more question feel free to ask.
