yeah a 450 cfm 6" vortex(top of line inline or get a canfan, fantech, ect. all about $150+ for 6") and i also have a cheap booster fan for exhaust on my veg cabinet. my veg and drying cabinet exhaust are hooked into the fresh air vent of my flower cabinet and i also have a passive air intake hose for my flower cabinet. i have 2 6"T adapters hooking in all the cabinets together. running my 600 watt light i get no higher than 83 deg temps so far.

the first pic is of all my chambers inside my closet. with the 2 hoses in bottom of picture as fresh air vents for the veg chamber and flower chamber. the chamber are big box in back flower chamber. on the bottom right of pic is veg chamber. on top of that in the white box is my drying chamber and to the right of that is my clone chamber

the second pic is of the exhaust coming out of the drying chamber going down to 1 of the T fittings

and the third pic is of the exhaust hose in the back is the drying chamber and the hose in the front is exhaust from my veg chamber(on my veg exhaust i also have a 6" booster fan to help draw more air through all the hose). both of those hoses meet up at T adapters and go to fresh air into my flower chamber

it sounds confusing as hell but you wanted to know
