exactly what Massah said. but let me ask you.. why are you using cooltubes. their suck as far as light disbursment. I'd imagine it's because you want to go with a sealed hood but ..... IMO i have a cooltube and they are shit for reflection. also you're using 1000 in cooltubes ....you're going to be placing them higher and with cooltubes you will be losing alot of light and affecting your yeild. go with a parabolic hood man. your yeild will thank you.

^^Agreed. Pull. Honestly, I think you're going to have substantial heat problems if you try to daisy-chain 4x1k watt lights no matter how you do it. I have 2x600 daisy-chained, and 2x400. The second reflector is noticeably hotter, probably around 10 degrees TBH. By the 4th light I could only imagine. And I'm not even running 1000s.

I will be using 2 8" 750 cfm blowers, 1 for each pair of cooltubes. The cooltubes are also 8 inch. I have done a 1 light system in the past with a 1k light 6 " cooltube, and a 6" 400 cfm blower with great results... I just want to ensure maximum cooling as I have always put the blower to blow through the tube not pull air

"I am setting up a 4 1000 watt system with coltubes. My questioni is which way shoul i have the blowers?"
Does anyone else see fail written all over this?
If you have to ask which way the air flows, maybe you should rethink your entire grow.

been toying with ur idea for a week or so now ! i av a 600 hps in a cooltube n a 400 hps in box type hood, but the tube as a a little flap of reflector on each side ( hardley sufficient ) just wondering if i put the reflector back on the 600 would i still be able to extract the heat ? as at the min i av the tube connected to fan n filter ( pulling the air ! ) think i will remove it asap n get the reflector back on ! at least y the weather is cold !exactly what Massah said. but let me ask you.. why are you using cooltubes. their suck as far as light disbursment.

idont agree m8, as this is a widley discussed issue , i personally av done both ways butnow i pull but just coz u dont no which way best to shift the airflow by no means sauys its gonna b a failure ! i asked the same question as a noob and the peeps on here vary from either push or pull ! its a good old noob question ! suck the air over the light or blow it over the light ?
just out of interest which way do u do it, lol. peace !

i had to learn that the hard waY My first grow the place i got my set up from told me to have it blow threw, baad idea its not as effective and wherever theres cracks or leaks that air comes back in which is just fighting yourself..i put it on the other side to pull and it works great, plus instead of some air coming back in its all going the other way...happy smoking

If you have to ask the question then you have no business running 4- 1000w setup. Yes your are right it is an often asked and answered question.
As a noob were you running 4 - 1000w when you asked the question?
Suck don't blow.

its a simple question pal. I have plenty of experience growing, just never cooled so many lights at once. Again in the past i have blown the air through, however this was only a 1 light system. Does it make a difference? Personally I think not. If a blower moves x amount of air pushing, it has to draw the same amount in.

IMHO theres only one answer it must be suck but not blow. There are two benefits
1st - to get cooler air in your closet you have to pullout hot weather. Coz if you blow it will mix with air inside the closet and will stay longer!
2nd - If you suck the air - you have option to filter the air with carbon filter to get rid of odour.
good luck!

Ok 2 is fine especially with 8" fans. That's what I have now too and man those things move some air.
And to the post above me, you know pushing air still means pushing it out of the grow tent/room, not back in right? The main reason not to push is so that any leaks result in negative pressure instead of positive pressure within the grow area. Also, how can you not filter the air based on where the fan is?? That doesn't make any sense.

Now that is the type of answer I was looking for....Thank you very much....

its not a bad question at all.... look at your pc case... you have fans on the front that pull air in and fans on the back that pull air out... your grow room/lights are the same... pull cool air into the room, then pull the hot air out...
