what can a 1000watter do for you ?

rather have 2 600's

lol with what? 600? 1000? air cooled? my tops stay about 8 inches from my bulb with my aircooled hoods

1000w! air cooled.. canopy stays at 74.. maybe I should move it closer?

How close is too intense for 1000w? Granted temps stay up to 79F max.. First time with this wattage.

Also reasoning behind two 600w instead of 1x1000w? Isn't 1kw the most efficient lumens/watt?

A 1000watts will bleach the leaves and cook them.

^ WTFF?? plz explain y, i doubt it if theres controllable heat wit no probs .......1000 watts will make the nugs big nd penetrate the canopy deeper also i say biggers better if u can handle it

With fresh bulbs I've never been able to get closer than 12 inches without light bleaching taking hold personally. (With a 1k)
My understanding is that a digital 600whps is the most well rounded ballast in terms of efficiency, intensity, and coverage. It provides intensity not completely unlike a 1000w. (Compare a 400 to a 600 and then a 600 to a 1000. The difference between 4-6 will seem astonishingly greater than that of the 600-1000 comparison) it generates less heat while doing so allowing you to get the lights that much closer. The bulbs cost less to replace in my area. And.for about 6$ more a month I get 2 more ft of coverage and an extra 200 w over the 1000. All the while generating less heat than most 1ks meaning less money spent cooling the room. Win win win IMO.

I personally am now running 2x 600hps and a 400mh in the middle in flower and 250w mh and 600hps in veg. Seeing great results (link in sig)

That's what I thought.. But I'm at 16 inches.. no problems or burn... I wanted to install an oscillating fan but I didn't.. I just have 2 6 inch fans running on the canopy 24/7.

The hood is cold to the touch.

i put mine bout 1ft from canopy but dont control the temps to lower it if ur temps r fine nd its not hurting the plants ne way at all, good! some people putthere light closer wit the right setup, nd 2 600s is always gonna be preferences of who u talk to , i want 2 1000 watters fuck 600s

i personally have never used a 1k but it CAN bleach the leafs. not sure how close it has to be but its possible. and im almost positive that the 600 watt is best for lumens per watt which is why i said that.

or better yet 3 600s

From http://www.eyehortilux.com/products/High-Pressure-Sodium#shps

wattage | intial lumens | lumens per watt

1000w - 145,000 - 145 lumens per watt

600w - 88,000 - 146.66 lumens per watt

400w - 55,000 - 137.5 lumens per watt

250w - 30,500 - 122 lumens per watt



So were looking about 1600 lumen difference 600w vs 1000w.. That's like a 25w cfl.. Pretty negligible to me.. Though I understand the benefit of using 600w lights when going a couple kw.. better canopys and stuff .



Good to know you guys are getting to like a ft from your canopy with no problems. I can't raise my light any further, but they seem happy so I'm just letting them go .

lol there you go 1.66 more lumens with the 600!
haha but really you also have the added advantage of being able to lower you lights a little closer with a 600.

It makes sense. Ballasts and bulbs are the worst for my wallet though. So I was happy getting 1 set that can grow all my medicine . If I had a lot to burn for 2.5kw or something I'd use 4 600s though, that makes sense to me.

How close is your bulb to full flowering plants with the 600w?

Just gathering information for myself . Thanks.

with my 400s the plants can actually grow up onto the glass almost of the air cooled hood. with the 600s it can be within 6 inches ide say. probably the same as the 400 if you have a good enough fan pulling air through the hoods.

Very nice. I ran a 400w once, and immediately upgraded . Plants are loving the air cooled hood with a closed loop into the attic..

I have intake from attic, into 1000w, into next tent, and into 400w hood(veg), and back into attic... I have 12,000btu AC running in the room with a 70L/d dehumidifier.. LOVE it. These colas are finally starting to chunk out.

nice! need to get an A/C powered room....

Verde. That recirculating loop on your Hood is almost certainly the cause of u not being able.to get closer. I'm assuming its heat related and not bleaching of course

Here's my 600w air-cooled setup in a 2x4 tent.

Here's outside the left side of the tent. Fan for tent, fan for air cooled hood, ballast and a variable speed dial for each fan.

Right side of tent showing two of the three intakes (third is below). I use cheap filter mesh on them to keep dust out of the tent.

Inside of tent with tower fan in corner for air circulation. I'm going to start loading it up in about a week or so.

View attachment 2461041
I attached a wireless temp/humidity sensor to the top so I can monitor even when tent is closed up. Have another one in the my seedling/veg cabinet.

Are those 2 carbon filters? If so I don't think you need the one on your hood ventilation and the other one would probably do better if it were in the tent.

I agree it's overkill but I have zero odor. The fan to my hood is running about 50% speed and the one from the tent runs at about 15%. Two fans at lower speeds makes less noise than one at a higher speed and I only have about a 4 degree rise over ambient in the tent.
