I need to choose an exhaust fan to cool my air cooled light as well as exhaust the air from my grow room and keep it cool. I dont have very much money to spend, but i dont have very much space either so i want to keep the light fairly close to the plants (4'6" from floorlevel). Basically what im asking for is a cfm recommendation for my situation.
The grow area: 2'10x3'4x8' Closet (75 ft. cubed) door will be closed
The light: 400w hps 6" ac daystar hood, lumatek digital ballast
The plants: 10 hindu kush plants (later upto 20 plants sog)
The temps: tested overnight w/ a lights off temp of 80f, 6-8hrs of lights on temps were mid 90's @ 7am.
The ventilation: air will travel closet-->ac hood-->inline fan-->attic
if there is any more information you need to make an educated recommendation please tell me.
also if anyone knows any cost effective ways to help lower the temps, such as insulated ducting etc, please bring them up.
basically im deciding between 150-450cfm's i dont want to underjudge but i also dont want to be frivolous.
thank you everybody.
