what is the size of your hps? i'm thinking you'll need more air flow than a 50-60cfm fart fan... i rigged up a box fan that works wonders. it replaced the bathroom fan, and the passive intake is enough to shake and blow the plants. so i've been able to x the oscillating fan as well.

i'll call a friend tomorrow... there's a guy i know who has several mh lights from a construction job. i got two 400w's for 50$. maybe i can get two more... some dissasembly required, these lights look like the outdoor ones at lowes (under the hangar...)

my personal two bits would be to let your hazies go to just over ten nodes, so when you top you'll have 20 main branches and a nice cutting for a clone mom (if it turns out female ~fingers crossed~)

as for temps, you realy don't want to let it get below 60, but i've had outdoor plants take to 50-40 degrees without too much harm... if you're having heat probs, i'd suggest using the hps, if for no other reason than use of a heater. my mh400 heats my entire room! and uses 700w less than a space heater...

remember to have as much room as possible in your flower room; it seems when you think you've got it perfect, it turns out to be too small... lol... just my luck i gess. i'm trying to get some new stuff going, so i have a little time left to make alterations before the grand 12/12 switch. i plan on having an 8x8x8 in the end... wish me luck (i have to go watch bob villa now)

merry crhistmas lbmom, and to all of you out there... may your lights be blindingly bright.... and may all your christmas buds be white

love, kp
