It is staggering to me that there are soo many indoor "growers" who know absolutely jack shit about light bulbs, light wavelengths, PAR, watts, Lumens, you name it. 991 posts and you come up with "CFL spectrum is 1,000 better for plants"
As someone said earlier...they produce the same amount of heat as the same amount of energy is being converted to light. AT any rate, your putting cart before the horse or so I shall, robbing peter to pay paul.
I personally like to actually grow marijuana, marijuana with huge sticky buds on them. If that is what you would like to do then quite fucking looking at CFL's, reading about CFL's or even thinking about CFL's (unless the light in your bathroom burned out), go buy an air conditioner on Craigs list for $100 and be done with already.
Jesus.
