Fluorescent lights are actually less efficient for plant growth than MH or HPS. They are nice though, because they're cheap and you can put them right next to your plants without having to worry about burning them.
khronik Reviewed by khronik on . flourescent for vegatative stage followed by hps for flowering would there be a big problem running flourescent lights for your vegatation stages and then switching to hps for your 12/12 cycle? im trying to find a way to not kill my electric bill. i havent really heard of anyone doing this but a friend suggested it would be a good way to get around a big grow. lets say 400 plants in 2 20x20 grow spaces. they would be light-isolated from eachother during the flowering stages. you would be 24 hours on during veggie stage for all 400 under the flourecsents Rating: 5
