Like i said it will always be a continuing argument, yes i am high and i've seen yields as good as hps with cfls....you can keep trying to prove a point, when i was simply giving the man the opinion he asked for. Done with this "cfl vs hps thread" you will stick with what works and i'll do what works for me, oh and btw from 20 inches away a 23 watt cfl will produce 80 PAR. So 8 at 20 in. away would produce 640...dont need a light meter when someone has already written this up at another forum. And you just compared 1 23 watt too one 200w hps of course it'll be stronger than one 23w cfl. done with the off topic argument
Whatever thread you are going off at another forum is wrong. You said that a 23w cfl will deliver 3300 lumens at 2 inches. I already proved that wrong. Besides lumens are lumens, it really doesn't matter what distance you measure at. Lux is a measurement of intensity. Lumens = lux/square meter. You can't increase lumens by moving it closer, only lux. My point is that the intensity of a 200w MH @ 8 inches will exceed that of a 23w cfl one inch away.
I guess my real point is that all your beliefs about light are incorrect, and need a thorough reexamination.
You're not gonna get a QP dry off 8 23w CFLs. Prove me wrong.
Your right, this will obviously never end. That's because CFL growers need to feel good about their decision to use substandard lighting, so they defend without question.
Its cool dude, I'm sure that you'll be happy with your harvest. I just don't want you making noobs think that cfl is somehow better than hid. Its not.
