How Do Cooltubes Euro Reflectors Work told Differnt Things?

Cool tube

push air from growchamber through cool tube outside

Euro refelcter

My buddy does it this way

Suck air from relflecter outside

Are these ways right im confused

Depends on what you are trying to accomplish. You can go from outside of enclosure, through your light, to outside of your enclosure which enables you to pump C02 without loosing any. If you do this you might need AC but again the AC wont be wasted and exhausted to the outdoors.

Or you can pull from the inside of your enclosure, through your hood, and exhaust outside the enclosure. This is good if you do not pump c02 nor use an AC unit as it exchanges all of the air within the enclosure with fresh air that is outside. This also enables you to initially pull through a carbon filter so what your enclosure is filtered of odors with the same fan you exhaust with - if you want a carbon filter with the alternative you will require 2 fans.

So it really depends on if you are growing in a sealed room or not.

I pull through my filter and my light then out the roof with the heat

i will not be using co2 and pulling air in with a 4''fan what do you guy recomend

so this is how it works correct me if im wrong....I will have a carbon filter hooked up to a 6'' fan that pushes air through the light and outside...then a 4''fan sucking in air for co2....right oh will a 6'' cool a 1000 watter

Yes that will work, you may not need the 4" intake fan, as the 6" exhausting will pull fresh air in thought a passive intake, therefore making a negative pressure not allowing any "contaminated" air to escape the room except through the filter.
6" Fans come in many many different cfm and water column ratings, so we can not tell you if a 6" fan would work, I can tell you that a 6" duct booster fan will not be enough. You need to go with a true inline fan or something like this: http://www.harborfreight.com/8-inch-portable-ventilator-97762.html

Wouldnt i want the 4''fan blowing cold air in from the outside??..I have inline fans ,cheaper one though name stars with a V ill find out

I would have the 6'' sucking air from the room

You could use the 4" but you may make more issue for yourself by using it rather than not. Lets use a bong as an example, most all of us have used one so this will be the best explaination i can do probably. To get the smoke to fill the bong you must first inhale the air, making for a negative pressure, now you are not blowing on the bowl to get air and smoke to come through, you are just sucking on the other side. Your room would do the same thing, by evacuating the air from the room it will build a negative pressure that will pull in fresh air from your vent(s). So rather than dealing with 2 fans you have made 1 do the same thing and made sure that you have accomplished the negative pressure. By using the intake fan you could cause a positive pressure in the room, because the filter, hood and ducting is all reducing the amount of air the 6" fan is actually moving. So if the 4" fan is open and moving more air than the 6" that is restricted you have now made a positive pressure and containing smell will be impossible.
It is recommended that you have twice the size of passive intake as active exhaust, so you would need 2 6" openings for fresh air this way, but it is how most of us deal with sealing in the smell.

well i need air to come in so would a 4'' for the intake and 8'' thats hooked up to the filter and cooltubes work........Cause i have to get air in somehow

You will never get what i am saying, i tried, you will fight yourself if you don't reread what i have said and think about air flow just a little bit. Good luck, im out.

If you suck on one end of a straw air from the other end enters... Listen to trueno. Think of your tent as a straw and the fan is you sucking on one end of it. Air HAS TO enter the other side regardless of whether there is a 4" fan there or not.

If your 6" fan connected to your filter and light is pushing 400 cfm out, then 400 cfm of fresh air is also being sucked into the tent at the same time by the same fan. This is called passive intake. No 4" fan necessary.

If i have a 6'' pushing air from the chamber through the tubes outside....How does it get new air if the chamber is sealed with out a intake through the walls and crakes???Its seems there has to be a intake

I uderstand the exhasut needs to more air to creat neg pressure...But the plant need c02 from somewhere unless you guys think it sucks it from the walls

I never said leave everything sealed, there is just no reason to put a fan on the ducting coming in, just having ducting in place and an exhaust fan will pull fresh air in.

Right now i have a sealed room with 2 vents one for intake and another for exhaustt..So I wont need a fan for the intake cause the neg pressure will suck air out

I just went to my buddys and he got me all confused again.. this is how he does it ..is this wrong he say's it get hot still

(He has one side off the reflector open) air gets sucked through that opening through the light..then to the 8''fan then outside

Shouldnt he have ducting on bothsides of the reflector with the fan in front instead of behind the reflecor pushing air through ducting then the light then outside

http://www.lightinguniverse.com/products/?tid=3189&psku=6830121&cse=1580 this is just like his reflector but hes doesnt have ducting on both side's he leaves on open and suck air through the lamp is this wrong
