Artifical lights too hot for seedlings???
I seem to have a problem on my hands. I started my cole crops indoors (first year under artificial lights) and they seem to be turning yellowish or even brownish. I have them on a stand under two T8 2 bulb shop lights. I have overdrove the lights so they are plenty bright. I place the lights two or three inches above the seedlings for 16 hours a day. They seem to be responding quite well until late this week.
I placed a thermometer under the lights and woah!!!! almost 100 degrees. I think they are being cooked under the light. I tried my second shelf down that has two more shoplights (but they are not overdrove) and it is still 85 degrees!
Everything I have read says to keep them between 60 and 70 degrees F. I do not have a basement or a garage. What are others doing to moderate the temperature under lights? I thought about a fan, but that would be a lot of trouble. Any ideas would be great!
