i drew a diagram to help show you guys what my ventilation sytem idea looks like but ive been trying to upload it for about an hour and it wont work so im goin to explain it with words.

The box is 60''H x 26''D x 30"w
the closet is twice the size
in the closet door about 12 inches from the bottom is a hole with a dryer vent cover as a passive intake
in the bottom of the box is a hole with a cover like the door for a passive intake into the box
on top of box is a hole attached to the vent for intake into my reflector (passive)
on top right corner of box is a carbon scrubber attached to a inline fan going out of the box
on top of the box is another fan exhausting air from the reflector
both exhaust line run into a T-connector wich is then hooked to the top of my closet to exhaust the air into the top of the room
both exhaust fans are inline 80 cfm

I dont know a lot about ventilation but from what i've seen yours looks good. I have had a lot of problems with the site the last few days. Cant answer post, Server too busy, or i just cant get on the page at all. Then when i can answer post it takes like 5 min to load. I dont know whats up with it.

Be sure you 'T' that into a bigger pipe to exhaust it. 6" line has more then twice the capacity of a 4" line. 8" is almost twice the size of a 6" etc. VV

so should i get a T that transfers into a 6 or a 8 inch

__________________

That 'T" is going to give you problems. You need a 'Y' splitter that will split into a larger diameter single... Also i think those are fan boosters, they don't move much air and probably won't be sufficient.

im sorry i meant to tell you guys the one for the reflector is a 6in 250cfm fan cause the reflector has 6 inch flanges and a y conector got it but this is the description of the fan

Rated at 250 cfm (cubic feet per minute)
Tried and true tools for the heating and cooling trade, wisely adapted for cooling grow light reflectors. An Inline Duct Fan is a reliable and cost effective way to keep temperature in the indoor garden under control. Use one fan per light or to increase the efficiency of an exhaust system. These economically priced fans have a lesser cfm (cubic feet per minute air exchange) than the high output CAN-FANS also available on this site. Perfect for air cooling a single lighting reflector or ventilating a small closet sized grow room.
Wired to plug into a standard household outlet!

6" Inline Fan

wich it is going to be used for a single reflector and another on is going to be used for a small closet

so will these be sufficient or am i going to have to send these back when they get here and look at something else

I use the 8" for a room that is about 10x20x10. I'm sure the 6" vented to the outdoors will the job. Major is right, your connection should be a 'Y' not a 'T'. With a t you have fan pushing against fan, not real efficient. If you are going to connect both lines together at some point, go with the 8" duct after that. VV

So i went to home depot today and tried to find a Y connection that would fit a 4" and 6" into an 8" and they didnt have any but they do have the supplies to make this and i was wondering if that might work
