Flower Room Situation.

Yes, there is static pressure but I can tell you that those fans blow for well. Probably the best CFM/ dollar out there. they don't do well with long duct runs due to static pressure but they work awesome as inlet/outlet.


It almost seems like we need to start over. Can't remember how big your room is but an air-cooled hood is going to add roughly 10 degrees to the room. My point with the AC is this... If it gets above 75 degrees outside, no amount of airflow is going to help your situation. Throw in the fact that the Midwest is humid as fuck and now your also running a dehu (more heat).

High or low, with proper circulation there isn't going to be much temperature difference. You have no insulation so in the winter, your nighttime temps will plummet and lights on temps will barely be high enough.

For the cost of inlet and outlet fans, temperature control modules, and lots of worrying you can buy a cheap window unit on CL install it inside the garage and forget it. As winter approaches you can buy an electric heater with a thermostat...problem solved. Temps are Important, very important actually.

Air con, heater, and a single 6" inline duct fan that blows air in for 15 minutes every hour and a half or so to replenish co2 would be my suggestion. Your pseudo sealed which will limit pest problems and you can control smell with a small carbon scrubber.

If you hook up contrifugal fan instead of a duct boster you wouldnt have that 10 degree increase. I sell both at my store. not hydrofarm but Suncourt brand. and my display has been hooked up to a Vortex util I sold it and now its hooked up to a valuline 6. The 6" duct booster claim 383 cfm but there motors noticeably quiet down when I get my hand near it.

The valuline however runs a freakin windstorm through my reflector and cinches all the ducting and pull my reflector and leans it on the end of its light rail path cus it pulls it so hard. I can reach my arm in my reflector and hold the tip of my finger on the bulb for forever and doesnt even get uncomfortable.

Since your room is 7x7 your probably going to want two sealed reflectors which would be easily do-able with a Valuline 6 and a 6" Y adapter vented out.

A duct booster works great for intake beacause your not fighting the static pressure of ducting. Your going through low density air to relatively low density air in your grow area.

heres an older pic of my display

How does this look? soo i'll be using the Vortex/ValueLine to exhaust grow room cfm but also to keep temps down, this might get me by with no ac. I will definitely be adding insulation though because of winter temps.

@Legallyflying, I will insulate it before I close the walls. and Thanks for helping me address my temps.. I've actually got a window ac unit already! Mounting that would be very easy, and I will get it ready incase temps reach 85+ in there in the summertime. Check out my sketch, this is what I plan on doing. I plan on using the valueline to exhaust both grow room air, and the bulb air at once.

That will work just fine. I agree that another hood would be nice. My room is 10x7 and I have 3 600's in a row that move back and forth on a custom light rail. Scrog screen measures 5 x 9.5'

Looks good if its what your working with heres a couple edits I made. You can pick and choose your upgrades

I was wondering, I may have missed something obvious. Can't I just intake garage air? Less pollutants, bacteria, fungi. Just a hepa filter and the 6" booster fan will do for intake.
