I need some fan advice. I ordered a 5’x5’x80” (tall) tent and a HLG 600H 3000k V2 Samsung QB light kit. Now I need to get a fan setup to control temperature and odor and circulate air. The room the tent is going into is unfinished so I have access to the HVAC ducting for the building. It’s extremely well insulated and the climate control keeps the ambient temperature in the room between 71°F/21.5C and 76°F/24.5C year-round. There are no windows or major sources of fresh air but I think there’s enough air leakage that fresh air isn’t an issue. If it becomes one, I can easily run a duct to another room or even attach a duct from the tent to one of the HVAC ductworks to draw air from the building (when the HVAC isn’t running) or from the HVAC system, when it’s on.
I’m thinking that the ambient air temp being what it is, and the fact that I’m running LED’s will mean that heat won’t be much of a problem; and that all I really need is a proper exhaust fan and a good filter. Noise is a real concern so I’m looking at a Hyper Fan Stealth or a Vortex S series in-line fan with insulated ducting and a carbon filter. What do y’all think? As a bonus, both of these fans pull very low amounts of electricity; particularly when run at slower speeds using the speed controllers. Both of these fans are supposed to be VERY quiet and they have really long, 10-year warranties!
My tent only has 175cu/ft feet of volume so a 6” fan will be plenty. But my research has found some folks recommending larger fans running at 1/2 speed/power for a much quieter system. For a few dollars more I could go with an 8” fan and run it at about 30%-40% and have MORE than enough air exchange for that 175cu/ft tent. Is this right or am I incorrect? What’s your advice on this aspect?
Filters: are they pretty much the same when you’re talking about a carbon filter and a pre-filter; OR, are there really big differences between them? For a tent the size of mine, do I need to worry about a high end filter or will just about any carbon filter do the job? I plan on using some Ona in the outer room. I’ve seen the Phresh 400 carbon filters on the lower end and the Airbox 1 and Airbox 2 on the upper end. What would y’all recommend?
Sorry for the really long post!
