I have a 50W tri-band LED from HTG. I'm doing some experimenting with some bag seed right now while I wait for my good seeds to arrive from Attitude. I will be growing in a 15" (D) x 25" (W) x 28" (H) cabinet lined with mylar. Right now I have 4 - 26 watt 6500k CFLs, and I plan on getting splitters for my sockets so I can add 2 more 6500s and 2 2700s (the bulb configuration will be reversed for budding).
That's my basic set up, so back to the question I know that I want to have the lights as close as possible to the plants to get the most benefit from them. From what I have learned so far, about 4" is good for CFLs... right? What is a good minimum distance for the LED? It puts out almost no heat from the area where the lights are, the only heat really produced by it comes from the transformer on the plug. I am going to set up a type of pulley system so I can adjust the height of it as needed, but I need a general idea of how close I can get.
Thanks in advance. This place is awesome! I have learned SO MUCH from here already
