HO T5 Fluorescents Good for Seedlings
September 17, 2018
Small fluorescent grow lamps don’t generate as much heat as incandescent lamps, so you can situate them much closer to your plants, especially young seedlings, for better results.
In a fluorescent fixture that holds four to eight tubes, you can use a combination of lamps with different color spectrums. If you buy a T5 fixture that holds eight fluorescent tubes and is zoned with multiple on and off switches, you can turn on only your blue lamps during the vegetative phase and then switch on the red with the blue to initiate flowering.
