I have two sprouted seedlings, with 4 100 watt equivalent 6500k cfls on them from two different clamp lights. " I got y splitters and put them in the clamp lights ", but I moved one of them down to about 2 inches from the two sprouts and according to my accurite thermometer, the temperature at plant level got a little over 90 degrees. If my thermometer is accurate then how can I keep it cooler with it being so close? And how hot is to hot for the seedlings?
