Ive recently bought a cool tube 600hps an im trying to decide which is best,to blow air in to the tube and out the tent or to suck air through and out via filter? Any one with previous exp plz advise....:eyesmoke:
 
Both way works good but if you can keep a negative presure in the tent with the filter you won't have any smell issue so sucking it is better.

this is how ive done it.. filter to fan to cool tube to ducking out of tent, i have input fan at the bottom.. I think im gonna change it around tough cause ive been getting high temps..
 
If its gonna be ur exhaust for your tent too u need to go filter,cooltube, fan sucking through both and blowing out somewhere high and outside the room. And that's one of the few things I agree with cervantes on. Not only will it help contain smell but it will also help keep temps regular.
Take a straw, poke holes into it then blow into it, ull be amazed how hard you'll have to blow to keep air from escaping those holes, now suck through it. If ur PUSHING all that heat through the vebts ur PUSHING it out of any and every tiny hole there may be, or a bad seal even. Where as if ur pulling, well all ur gonna do is pull somewhat unfiltered air out of the tent, where it needs to go.

Wait, Are u pushing air from the light to the into the filter? If so that's ur problem. Ur filter will be most effective when air is pulled into it

Alright hybrid.. Going to try out what sensi said first if no good gonna get 5"exhaust for cooltube out of the tent,and leave the 6" exhaust on the filter plus 5" input fan..
 
all wrong answers, all work some ,but not really the right way. you need to run vent hose from an outside sourse of air (outside) into cool tube and then back outside of living space. ( out of your home or into attic). push or pull does not mater depend on the fan manu.. you dont need the filter because the air cooling light does not mix with the air in tent so there is no tranfer of smell. also those filters lower cfm which lessens the cooling ability. if you dont vent the air from the light back outside living space you will heat up your living space. if you vent air back outside but your getting that air from inside tent or from living space your creating negitive pressure in you living space which will again cause you living space to get as warm as it is outside your home because the air outside you home will leak in because your creating a vacuum. thats how you properly cool the light. to cool the inside of tent you need a seperat can fan. you put the filter on that fan and pull the air out of the tent ( not the lights) into the room the tent is in. this way the grow area will be the same temp as the room the tent is in.
 
2 4X3 RUBBER REDUCERS. I USED A SMALL STIFF WIRE ( WIRE CLOTHES HANGER)RUN THROUGH THE 4in END BOTH WAYS LIKE TEE, AND THEN SCREWED THE LIGHT TO THOSE 2 PIECES OF WIRE WITH WASHERS TO HOLD THE SOCKET STILL

Mike ,figured out most of what u said .. There not wrong answers mate ..I dont think you read all the posts from the start --- Id never listen to some one whos claims to Know all the right answers,especially on a forum!! Plus when the Guy has NOT 1 pic of he's grow.. LOL
Busted with 2grams,Your a joke mate...

Different things work for differernt people, its only wrong if its gonna cause damage/harm the plants in my opinion..My opinion doesnt mean im right either...

Beef-- Eh? I think ur on the wrong page mate...

Hi :)

Just want to chip in here with a little tip for all you Cooltube users , I see a lot of pics around the net and they are set up wrong more often than not ...and heres why ...

People seem to overlook the whole idea of how they work and put them the wrong way round ... Your air intake needs to connect to the lamp fixture end of the cooltube so that cool air passes over the fixture befor it goes over the lamp... and then out .

If the cool air hits the lamp first and is sucked past the fixture on the way out ... IT HEATS IT UP ! :)

That hot metal fixture and all the metal around it heats up ... This adds to room temp and interupts the flow out of the exaust ducting ...It can get pretty hot .

Might just sound like common sence ... But you would be supprised how many people i see getting this wrong :)

Hope this helps somone :)

That's the right way to do it.
 
I have 6 cool tubes and i push the air through all the lights i don't want all that heat going through the fan. but my room is sealed with co2 so i suck the air in and blow it through the lights and back to the outside world.
