Question about cool tubes

[zingablack]

I understand it's more efficient to pull air through but my concern is that it may pull some air from the grow out an smell uP the place. In this case would it be ok to push through so if there is a air leak it just goes into the grow. Then pulled out through the carbon filter

most people do a "clean intake" (outside air, not flower area air)

so they dont have to scrub(restrict flow) the cool tube exhaust.

oh i am exhausting using air pulled from outside it will be setup somewhat like this l_l with the bottom line being the light and both vent tubes going out the ceiling. i have a separate filter and fan. i haven't decided between a sealed environment, or vented. so I'm making possible whether i decide to or not. i pretty much have to buy an AC since its an attic. so i figure i might as well run co2 and go sealed.

my concern comes mostly from experience with so called sealed lights that didn't meet my standard of quality and leaked air from a few places. on the other hand it really shouldn't be a problem right, since air follows the path of least resistance, in this case the 6" tubes.

The intake vent/duct for the cool tube can be outside the grow room and the scrubber on a separate vent/duct and fan mounted inside the grow room. So there's 2 exhausts, one for the lights and one for odor/scrubber. The fans in each case are mounted near the exhausts so it can "pull" all the air out (not push) as that's how they usually operate efficiently. Just make sure the ducts for the lights are sealed and no odors will exit there.

Pretty much exactly what's planned. thanks haha

Thew op`s question still was not answered, what hes trying to explain is that, by sucking through your lighting venting system, you could suck GR air into the tube and then out of your fan unfiltered, in which case he is absolutely correct, HOWEVER cool tubes are pretty well sealed, and the amount of smelly air that gets sucked in and pulled through may not even be enough to have and effect, either way cool tubes are so efficient, at their "cooling job" (light spread is a different matter), that push/pull, is not going to make much difference, provided the the extracting end of the venting system is not restricted, anyway for what its worth, I ALWAYS have fans before my lights, as apposed to after, I do not leave nothing to chance.

pushing is better than pulling air thru a cool tube cause the fan stays cool works more efficiently... also any air that escapes when pushing thru cooltubes is clean... when you are pulling air thru them then grow room air that smells gets sucked into the exhausted air little by little...


hard to explain for me now hahah, hope that makes sense...

fact, pulling is more efficient,
you can push tho
worried about sucking in smell using pull?
seal the system, its very easy to do with CTs.
