helping a friend set up a new flower only room 4x8 he is thinking about going with 3x600 or with 2 1000 what do you guys recommend ?
 
got a slightly bigger area.. 4x10 thinking about either 4x600w or 1000w/600w/1000w on a light rail track... haven't decided
 
Baby plants never get enough light, better is 4 400w hps, each able to adjust separately for plant height
 
I don't want to down talk Vostok or degrade his advice but I would think 3 600w would be better for more penetration into the canopy. If you could do 4 600w you would be very happy so long as you have adequate ventilation.

I would run dual 4x4 vertical doughnuts with 2 levels of plants and either 2 600w per doughnut or one on a light mover.

If you want more info on something like this check out the vertical section or pm me
 
anything over 1800 watts for 32 sq ft is overkill.

50-55 watts per square foot is the saturation point, more watts is not beneficial after that.

so i'd vote for 3 x 600, but do whatever you want.
 
pack as many 600 in that room as possible. the more light the more yield ! keep in my the 600 less heat cheaper to run then 1000. my opinion 600 are the only way to go in home use .

have you ever heard of the law of diminishing returns?

fixed it for ya ;)

from what i've read and seen 60w.sqft rocks the house bro. or 1k/4x4

also what snaps recommends. He does design rooms for a living :)

well technically it works out to 62.5...

i know how to divide 1000 by 16, i was pointing out that even that may be overkill. from what i've read here and elsewhere, light saturation occurs slightly before that. about 50-55 watts per sq ft as i said.
 
3x600's. What method are you using to grow. 2x600s would be adequate say if you scrog on an ebb and flow table or even an nice undercurrent system. Most I pulled under a 600 was 1.1 lbs. that was under a scrog net. I have a 4x8x6.5 tent
 
3 x 600 might seem good on paper but in my tests we found slightly better yields from a 4x8 area using two 1kW lamps. The fact that you have the added expenses associated with three lights, there was no gain but rather a slight loss made it a no go imo.

Penetration is better with 1kW lights, spread is more even with the three 600's however its meaningless imo since my runs with two 1kW lights have even canopy.

If I was running 3 foot wide trays I would use 600's all day long.
