Hps for sure bro!! Unless this is some sort of test run, and you arent concerned w/your harvest. Ive never had comparable results w/leds
I'm probably going to go with the HPS but to be honest I've got 2 successful grows under my belt, one HPS (SCroG), one LED (Regular) and it seemed the LED grow had much more problems (LOW PH and dropped root ball) then the HPS grow. I still managed a decent crop and ALL my nugs where dense not airy at all tops to bottoms but it did take longer to start to flower and longer to finish. The worst thing about this is the damn company's scetch artist doing these nm spectral drawing of the different shades of light "THEY ARE" using not just LED company's it's the HPS/MH bulbs too, I have both Digilux HPS and
Ushio HiLux HPS both have their versions of the nm's they are focusing on and if the drawings are correct by any means the Digilux looks better, far more in the orange/red not so much green/orange like the
Ushio one shows. I've used the Digilux once and someone told me to not use it again so I got the
Ushio, was told it is a better bulb to use.
I guess to each his own, I'm in HELL and it's hot down here in summer so maybe I'll benefit from the LED in the summer
