[fatpat369]

im kinda confused on the whole fan situation i was going 2 get a Vortex PowerFan but i dont get if i need 2 of them or if the other fan is a different type(one for blowing out air one for blowing or sucking in fresh air) ....

if someone could please describe 2 be how it works i would appricate it greatly

You can use one fan for exhaust with a passive intake. (just a hole to allow fresh air in)
Then you will need an oscillating fan to blow on the plants to help stengthen them and to move the air around the room. You will need to make the passive intake light proof in the budding area. There are many different ways to do this. Good luck

^^ Yup.
Since heat rises, exhaust hole (for the exhaust fan) should be high-up in the cabinet/closet. Intake hole should be lower, twords the floor. (no fan necessary for intake)
Both holes need to be lightproofed.

How do you guys go about light proofing the passive intake holes?

[syde00]

just build some kind of "U" shaped duct around the holes.. kinda similiar to the trap drain you'll find under your kitchen sink... air can go around the U shape, but light will get traped in it as long as you don;t build it out of a highly reflective material

So then do you need another fan for the light? The exhasut fan would be connected to the carbon filter, but a second fan would be needed to exhaust the light?

uhm... what? what do you mean by exhaust the light?

the only way you could 'exhaust light' would be through using a light conductive material like optical plastics or by using an elaborate series of mirrors...

bbbbbuuuuuutttt......

thats exactly what you don't want to do... any light inside your grow area you want trapped inside your grow area, and any light trying to enter your grow area from outside you want to block from entering the grow area (at least during your dark cycles)....

ssssoooo i;m really confused as to what you are asking

[Italiano715]

I think he is asking if he needs another fan to keep the light cool.... IDK though...

Exactly...do you need one for the light and another blower for a vent system or can u run it all through one?

[KillerBudG]

If I am correct you are talking bout light a cool tube/air cooled hood.? If so just run you exhaust to bring cooler air straight to the tube/hood, then get a duct Y adapter on the other side this will allow you to take heat from the light straight out the box. And is also pulling the hot air in box/closet out also as hot air rises. Than hook your carbon filter up to this an than your fan. Another way if you wanna do it is have your exhaust system ran directly threw the light. Then have a passive intake with an exhaust fan just pulling hot air out the top wit filter on that. If you got sealed hood I don't think you would need a carbon filter on that exhaust but not 100% sure. Hope this helps you out if not good luck figuring out your set up.:thumbsup:
