shows what you know about lighting tech do some research before spouting out info that is completely false
I would pick CFLS over LEDs anyday and i would pick hps/mh over anything
HPS is a thing of the past and so is standard MH for HID growing if your going HID take a look at plasma/induction fixtures with external ballasts or take a look at CMH nothing compares to those for HID growing anymore. HPS is a WASTE OF TIME MONEY AND POWER. My 240w led that happens to be a blackstar is growing 30 plants on a 2x3 table better than ANY 400w hps i have ever owned. I would say with blackstar the 300w led is equiv to a 600hps and the 240w led is equiv to a 500w HPS.
The ONLY thing to consider with blackstar is their extreme spectrums. Extreme red for flower or extreme white blue for veg. They dont have one in the middle but that is part of the reason their lights perform so well. What i would do is keep your CFL for veg and switch to LED for flower OR supplement a few 6500k spectrum CFLs if your using the flowering blackstar for veg as well. That way you dont accidently have flowering induced early by the massive red spectrum. If your only veg for a month thats no big deal but 3 months veg is too long for a flowring blackstar panel alone it would need some supplemental lighting from 6500k spectrum of something.
A guy named hudson is doing some interesting experiments involving comparing an hps combined wth a panel and a mh combined with a panel. He claims that with the MH you get WAY more UV (the main reason he is using it besides the real main reason which is he needs the added heat its too cold.) and that increases trich production and the massive reds in the blackstar produces dense as hell nugs. Some interesting stuff. I see HPS and MH being phased out slowly as LED tech gets better and induction tech gets better. Prices have come WAAAAAAY down on LED's at least if your buying blackstar which is the ONLY company with a cheap LED worth going with the expensive companys have good products but they are way overpriced for the performance which only equals or BARELY exceeds my blackstar and so minimally that it would be pointless to spend the extra 500 bucks they want.
