I recently got back into growing, but all of my experience is outdoors. I’m trying to get things dialed in and grow a few plants under a HLG 320 LED.
My space is a 2’x6’ closet w/ 8’ ceilings. It’s located in a small guest “house” just behind my home. The structure is only one large room with the closet and I use it for my home office.
When I set it up I figured I needed an exhaust fan to pull in new air and blow out the old. So I installed a 6” hurricane fan that is vented into the “attic” space….but it’s not really an attic. For our purposes just assume it’s routed straight outside. I don’t have an intake fan or vent. There is a sizable gap under the door and it passively serves as the conduit for new air.
I run the exhaust 24/7 because I figured I needed to. It’s so powerful it sucks all the humidity out of the space. It’s winter here and the air is cold and dry. I’ve had to run 2 and sometimes 3 humidifiers in the closet just to get my RH to acceptable levels……my plants are in their final days so I’m keeping my RH around 40%.
My question is do I need the exhaust fan at all? I’m opening the door to look at the plants multiple times per day. Plus I’m in the office quite a bit.
I would rather run a CO2 tank than continue with this exhaust and monitor these humidifiers, which need filling twice a day.
I bought a speed controller for the exhaust and it helped but not enough.
Someone suggested putting the exhaust on a timer but I can level out the temp and RH if the exhaust is off.
So, do I absolutely have to use an exhaust fan? I’m not worried about the smell.
If i don’t run the fan should I still leave the area vented? I run two oscillating fans to keep the air moving.
I’m just confused about what the plants really need. Any advice is appreciated. Thanks
