Air cooled Lighting, NEED HELP!!!!

Funny...




just as suggested... did you see the drawing?

The exception being the 2 shitty axial fans... I say it's better to put one at each end... thinking of loss of cfm and disregarding fan life, as this is a temprary solution... he is already looking for a real fan...

we're in the same boat friend. i got an m-6 (thats wat its called, made by chinese i'm sure). got it off e-bay for $89 w/ shipping i think $105 to my door(rated @650cfm). very powerful fan! i blow through 2 600w's and through the wall. those duct boosts are only good enough to add a few pounds to ur hvac system in ur house. they are designed to boost air to long runs of hvac venting in ur house. like a bedroom farthest from your furnace. they are usually used in conjunction with a ductstat. they are a fan, but are not your solution poster. also gypsy, htg is a great source, that 4" is commonly called the m-4. i think you showed him exactly wat he needs!

Thats the one Im thinking of getting the 4" from HTG. Will that be fine using a 4" to 6" conversion through 6" ducting, or will I lose cfm's.

it would be fine...

how will your ventilation be setup? like that drawing by Al B. Fuct I showed you?

Should I position the 4" htg fan outside the grow area, with ducting to the light then, duct the other side to an exhaust outlet. Or would I use the opposite a sucking movement. and is only one fan good enough to do this???

I also thought I could mount the fan on either the exhaust or intake side of the light, then a diff fan (outside, or mouth to mouth with exhaust hole in wall) to pull in fresh air or to exhaust heated air.

Which sounds better ???

This is the IDEAL arrangement... with the intake blower being optional on most cases...

Put your fan before the light as the drawing shows...

Working with cooler air will be beneficial for performance and longevity of the fan,...

There's not many ways to do this... but this is a proven one...

I'd follow it...

I agree with GypsyBush it seems it would work fine.

that arrangement with a thermostatically controlled exhaust will give you the best temperature control with aircooled lights...

Using that arrangement, I have powered a 20"x36"x54" homemade tent with a 600 HPS and zero heat issues...

And that is what I still use in my op today...

I think I have my setup figured out. Thanx for all the help, when I get it setup I will PM you some pics and you can tell me what you think!!!

I like the S&P's (TD150 here) They are a hybrid design. Small, quiet, and effective. Can also just flip the center cartridge and it flow the other way.

Push pull? Push if the blades are plastic (hot air on plastic, not a great idea)

I also like push over pull because it gives more air molecules over the bulb. More air, more heat transfer. (IMOHO)
