Ambient temp in the room 70*F ......450 cfm exhaust

Tent with a 1000 is in the 80s...... tent with a 600 is in the mid 70s.

Lumens fer sq ft......4400 lumens per sq ft with the 1000s...only 2400 with the 600....great gardens stay above the 3000 mark

I did 4x6 once with one 600 and a light mover.
I just finished a 4x4 tent grow with a 600, and it was quite adequate.
Now for that space i would supplement with 100-200 watts of actinic (color temp 10000-12000ºK) aquarium T5s for the win! cn

lumens are pretty pointless when talking about growing plants. they are the measurement of visible light to the human eye and mean absolutely nothing when growing a plant.

1000w or supplemental lighting like canna said. if your hood is vented correctly then you should have no problem cooling a 1000w light in that tent. it's just a matter of correct setup.

42"x84" with an adjust a wing and a 1000w works good,
just get a super spreader and run the light about 10" off the top of the canopy and give it a lot of air flow, many will say thats to close, but if you can keep the room temp under control, and flow a good amount of air between the light and top of the canopy, its just fine

if you want to run the 600w I would go I would run the bed only 3-4" wide and go 5" long, I'd run the 600 even closer, 8" or so

really...well slap my face and call me a dumb wihite dude :)
.

when I use my light meter the 1000 has almost twice the footcanldes as the 600.... just like the 1000 has almost twice the lumes per sq foot as the 600 hummmmmm

thats why they tell you a 1000 covers a 5x5 - 6x6 area sq..... that gives you 4200- 3055 lumens per sq foot....anything above 3000 will be a great garden

I dont use the cooled hoods .....theres no need to if you have adaquit exhaust

In our commercial grows.... we set up 1 - 1000 wattter per 6x6 sq and average 12-15 lbs

i've been a member here for 2 years now with this account and my old one. any chance you are gonna get a "new" picture of this "commercial" grow. i've seen that SAME EXACT 2-3 pictures 50 times in the last 2 years. again, you are talking about lumens and that's pointless in my opinion. lumens don't grow plants. you'd be better off at least saying watts per square foot or something. at least then we'd be getting a more realistic idea of the amount of usable light in the space.

you state that you don't use air cooled hoods cause you have adequate exhaust. sorry, but this doesn't apply to every sitaation and is false. if so then you would be able to cool your tent with a 1000w light in it if you had adequate exhaust. sometimes exhaust isn't enough or growers are working with sealed environments and an ac is needed. if you are in a basement in house in alaska then maybe not; if you are in tents in a garage in arizona then good luck with your "adequate exhaust." also, if you don't mind me asking...why are you using parabolic reflectors in your "commercial" grow? everyone pretty much know that they are the least efficient reflectors hands down. also, you are vertically hanging MH bulbs 3' above the canopy in a parabolic reflector. i couldn't think of a more inefficient way to light your space.

when i use my light meter a 600w doesn't have twice as many fc as a 1000w. maybe 30-40% more. none of this has anything to do with the OP's question and your comments about heat. 1000w bulbs run hotter, everyone knows this. doesn't mean the OP shouldn't use them if he is trying to maximize his footprint. he should just look for a way to cool the area adequately. just because your tent is hotter using a 1000w light doesn't mean everyone environment or setup is the same as yours. the 1000w light in my veg tent has been running non stop for months. i could go lay my face on the glass right now.

I have wondered lately if I am beating light down on my plants harshly. Love the tight buds am getting here. But probably would yield more if raised the lights up more and fit in more plants.

Love the tight buds though.

Have recently become stuck in my ways for the first time in a long time. Need to change that.

That's the thing about all these threads. We are all just giving our opinions.

We have gone over the lumen thing many times. Just to help clear it up. Lumens are needed for a good spectrum. And when tested with a meter it will tell you if your bulbs are starting to loss there afective glow. But the over all PAR rating is what the plants need. The OP just asked would it be enough light for that area. Simple answer is yes if lined with a reflective surface. It's easyer to cool and supplemental T5 lighting can be added to cover any dark spots later if he wants. With a 600 he will be only getting around 24w a squar foot, not the best but adiquit.

When talking about watts per sq foot or lumens per Sq ft.... its all the same http://www.growmedical420.com/894/how-many-lumens-or-watts-per-square-foot-of-light-do-i-need/

It depends on how you looking at it

Your a fuuny dude.... how you seen this in 50 posts for 2 yrs is way beyond me...that photo was last sumers crop

Ya a 600 will work...a 1000 will produce you more product......... a 60,000 lumen bulb doesnt produce as good as a 110,000 in the same sq ft area

A 600 doesnt leave any dark areas..... heres a veg 5x5 tent with a 600 mh.... using a 4ft parbolic hood
