You're missing the point as well, I think. There's no argument that MH/HPS is superior to CFT for growing.

The point is that CFTs are excellent in tiny, enclosed spaces where ventilation is an issue. Very stealth. Try putting a 150W HPS in something the size of an office copy paper box. You can easilly put 150W of CFT in there. You won't get the same results you would with a 150W HPS, but you would get results.

Again, I must stress that HPS is the "tried & true" light of choice. Superior for growing in a grow room in every way. But it just ain't gonna work in a "shoebox" without major hassles.
Volker Reviewed by Volker on . HID vs CFL in a small one plant situation, given light spectrums being ballanced between each situation and all other factors the same, would you see a difference between ~300 watts of CFL, and ~150 watts of CFL supplimented by say a small 50 or 75 watt HID? my main areas of concern are with potency, density, and mass, as well as time till maturation.
