Air Circulation Question

Okay, I have a difference of opinion on the way my fan for cooling my lights should be set up.
Zandor tells me that they should blow the air through the fans; I have it set up so that the fans are on the exhaust side of the lights and draw the air through the lights.
I still fail to see what difference it make unless it's just personal preference.
I'm really at a loss on this, because I just don't know what diff it makes; air is air, and it's going to take the same amount of energy to pull the air through the lights as it will take to blow it throught them.
It's like 6 of 1 or a half a dozen of another to me....

I think here as been a misunderstanding..

Zandor would tell you to pull air through the lights.. Never blow air into the lights..

There is a reason for this.. A very imporant reason....
Just can't remember it right now. hahah

You want the fan to draw air from your lights and blow it away from your GROW!!!!!!

love

Zandor, you wanted to get this on the board, right ?
You ain't exactly contributing a lot here.
What's your opinion ???
I'd just like to know, and why.
Thanks.

You got an answer and a good one at that.

He's on vacation... he left a post somewhere... you should have read it...

fans blowing on plants to strengthen/thicken stems. fans sucking air for cooling

A bulb might as well have the aerodynamics of a brick. Therefore if you want optimize your air escape velocity, you don't want your fan pushing air towards a brick.

very well put stickyy :rasta:
