After seeing my electric bill I'm creating a second flowering room which im very pleased about now happy to add another 250w for more flowers!

So what's better same Watts the envirolite seems great for me because it does not need a balast or anything to cool it, very easy set up but will it do, like a HDS 250w? is there a difference, i have never used one to me its about cost so i can in theory i could if needed use the HDS . Its all about results given time and power used.
