Ya kris, ive heard and seen the outcomes of HPS bulbs, and want to try my hand at it ive only done a cpl soil + all cfl grows b/c i thought the heat would be too much with an HPS, but ive recently come across some 70W grows and i think i can max its efficiency in my cab. 1000bulbs has a 70w bulb for like 6$ and a ballast for 22$ + 10$ shipping :thumbsup: gonna have one fan on the bulb/exhaust, and one for intake; if i can get away with 3" max distance from bulb i think ill be good for the end. current(smaller) box has 6 x23w cfls with 2 fan setup and is completely cold.

Thanks for the idea :rastasmoke: maybe as supplement lighting, but i was under the impression that 5k lumens per sq foot was the goal for flowering? that light says 500 lumens..

If i have 1.5 Sq Ft, = 7500 lumens should be optimum.
the HPS = 6300 lumens
and i will supplement this with the 6+ CFls i have.


post needs some pics kinda off topic, but a few shots of the HERM under only CFLS
