I am thinking of bulding a five bucket, DWC set up in a room 11'x11' wide. They will obviously not take up the whole room, but will most likely take up an area of 5'x5'. I plan on building a frame to put around the buckets and cover it with mylar, so that I will end up with an area enclosed with the reflective material. The room is not heated, but can be ventilated. I live in Maine, and winter is coming up, and in the summertime, air conditioning can be put in the room. I am wondering what the best lighting solution would be. I was thinking about getting a 1000 watt light with a dimmable ballast and an Adjust-A-Wing reflector with their SuperSpreader. Is this worth it? Their website makes it seem like you can get this sort of light closer than most others, but I DO like the idea of having something that I can air cool. If it is in an area with air circulating constantly, or in a basement, is heat going to be a problem? If I have a fan blowing over the light, will this help? Would it be wise not to get such a powerful light? I am trying to figure out the most efficient way to light my plants. I would like them to get as much quality light as possible, of course. I have not set anything up yet, I would like to get the opinion of people much more knowledgable than myself before I do anything.
