It sucks when people that sell stuff don't even know what they're selling.

I do think you can grow weed with just red, which is of course more important than the blue. Many people grow weed with only 3000K fluorescents. Without blues your plants will end up stretching to some degree, and end up less bushy. It's not a problem as long as you are willing to work around it. Your yield will not be quite as high, but again, not a problem.

Instead of mylar I would paint the interior of the wardrobe flat white. It does a better job at reflecting and diffusing light. Also your walls will get dirty and the mylar will soon dull, and splashing another coat of paint on is easier than replacing the mylar.

Looking forward to your tests.

This thread will be a diary of my experience as I work through some of the many design problems. Currently I am at the circuit design phase. Although I do not want to reveal too much of my design at this point I will provide some information that has guided my decisions. The LEDs I will be using are from Lumiled. I am using the Luxeon K2s for the blue spectrum, and Luxeon IIIs for the red spectrum. The ratio of RED to BLUE (I will call Rating: 5
