im in the same boat , i have a 4x4 tent with a 600w system, i hear everyone saying 1000w is better, but how low can u get that 1000w to the plant? and we not even going to talk about venting, ok

FWIW, my 1Ks hang about 18" above the center of the canopy and ~12" near the sides. The plants are setup in a coliseum-like arrangement. Sometimes, when a plant is bigger than expected, it actually touches the glass. One could say its flowers are 0.1" away. There's are a couple of example below of plants that literally sat touching the glass, albeit setup for relatively indirect light:







This isn't to say that one can't grow big buds with a 600. It just requires a slightly different approach:





As you can see above, the 600s can hang literally inches from the canopy, given sufficient cooling. All this being said, I see significantly more yield per square foot under the 1Ks and the quality of the flowers, themselves, is a bit better. YMMV

If you have the money too buy 2 600W HPS I would go for that. That will equal more lumens for your plants. And the light would reach in better. But more easy would to buy adjust-a-wing with 1000 light bulb. The reflectations are incredible...

I agree.thats why i went with 6 600 watts hps rather than 4 1000 watts hps.
Less heat..
More points of reflection..
Closer to the canopy..meaning more lumens.

No matter what the setup, you do NOT get more lumens from less wattage when it comes to HPS. Ever.

That's one of the dumbest things I've ever seen typed on this forum.

Explain to me..instead of simply saying that a post is...dumb.
Ill at least explain my theory..
A 1000watts hps..
At 18 inches from the plants produces 19,806 lumens..
A 600watts hps..
At 12 inches from the plants produces
29,285 lumens

Oh..try running a 1000watts hps at 12 inches from your canopy .
Good luck with that

Wow. You're even dumber than I thought.

The typical 600 watt HPS bulb produces 90,000 lumens.
The typical 1000 watt HPS bulb produces 140,000 lumens.

Put in a properly vented housing, the heat from either one is nearly the same. There is absolutely no reason to ever run a 600 watt HPS at 12 inches. You're BBQ'ing your plants anyway. The documentation on any high power HPS lamp will tell you that under no circumstances should it be any closer than 13 inches.

18 to 30 inches is ideal for a 600 watt HPS. Not surprisingly, the 1000 watt HPS overlaps that same distance with a recommended range of 21 to 36 inches.

In the end, the only real difference between the 1000 and 600 watt HPS is the amount of area they are capable of covering.

Since the OP's area is 8 x 5, a single 1000 watt HPS would be fine and cover a 6 x 6 area of the room. It would take 2 600 watt HPS's to do that.

You're an idiot and you're giving very, very bad advice.

talk about idiotic advice. a 1000 w in 36 sq ft is 27 w/sq ft which is pathetic. 50 w/sq ft is the minimum for hps/mh

aren't you the guy that swears that miracle gro is the best nute too? idiot.

a 1000w hps produces 400w more of heat, you obviously have no clue what you are talking about.

You're talking about MAYBE 4 to 6 degrees overall difference at most.

Do I REALLY have to do that math for you as well or do you think you might be able to work that out on your own?

You might want to read what you said here's a quote

"Put in a properly vented housing, the heat from either one is nearly the same. There is absolutely no reason to ever run a 600 watt HPS at 12 inches. You're BBQ'ing your plants anyway.

ANDDDDD second quote

"In the end, the only real difference between the 1000 and 600 watt HPS is the amount of area they are capable of covering."


reading comprehension is not your strong suit.

I often run my 600hps at 6 inches and it doesn't BBQ the plants.....

Do people just type chit they haven't done and then say its gospel?

A 600 at 6" is certainly BBQing the plants, any idea what the hotspot is at that height? Its likely outrageous

How so? No idea, canopy temp low 30Cs normally, no bleaching and no canoeing (maybe some very, very, very slight canoeing of leaves)...just a pound of scrog...

I often run 6 to 8 inches above canopy with 0 issues. Have you tried it and what issue did you get? What was your canopy temp?

I run an enclosed hood 600hps @ 14" and have a canopy temp of 75 in general

@ 6" you were getting no coverage with that light, just a concentrated hot spot

I beg to differ.

Using a Sun system XXXL hood I get very good covg. Even with just a cool tube I got a great 3.5 x 4 canopy coverage. In the end that was a pound dry (scrog). See any major heat stress? Me either.

Pic of cool tube and canopy.

Sun system hood. Huge coverage with these large hoods. Perfect size for a 4 x 4. Pic is for size reference. Some problems with these plants but they were me related and not heat from light related. They did end up OK in the end.

Maybe try a lower height before saying its going to BBQ them as if its gospel.
