Hello ledtime,

In this dirt grow I'm envolved in, I use blue light over my cloner and seedlings. I get it by using a super actinic white T5 HO, first few days that bulb only then 6500K T5s are added. Found it cheaper and easier then LEDs in this case, but i'm loking forward to seeing what you get with an all blue LED setup.

(4 reds, 1 blue, and possibly 1 warm white; LM 317's so I can tweak the ratios.) Essentially, a copy of your 4+1 cake pan lamp but built on a 4 x 18" finned heatsink so I can see what's going on under it.) If I were to post my picks for power supply, resistor ratings / values, etc., would you critique and perhaps offer some guidance? I have already purchased Rating: 5
