Essentially using the attic space as an air treatment space dealing with all the issues created by venting warm moist air into a presumably sealed attic and using the water and cold air generated to further improve the grow room.
Grow room exhaust into attic.
All along my plan was to cut a hole in the ceiling attach fan and exhaust into my attic.
Your grow room is going to be bright and attics have less places for light to leak out and alert neighbors.
Exhausting into the attic would be super easy but again i pause with reservation of mold concerns.
Ok so i m using a grow tent in my closet 20 x 36 x 64 from htg and my only worry is ventilation.
Is this going to cause the bud smell to permeate the house.
My grow is in a small closet in a spare room of the house.
Open loop grow rooms consistently provide fresh air to the plants in one of two ways.
Tip 3 of 7.
I m not too sure on how if the attic is vented.
Wondering what size inline extraction fan and carbon filter you need for air exchange in your indoor garden.
Keep the exhaust intake holes at opposite positions.
The outside source of fresh air could be a separate room in your house the hallway an attic basement cracked window or even directly from outside if.
Either an intake fan that pulls air from an outside source or a passive exhaust system pulls in fresh air by forcing old air out through an exhaust duct.
I just went to cut the holes and had a thought.
Grow room design setup venting ac to attic.
I will have one 6 inline fan running air through my 400 hps bulb have a 6 exhaust at the top of my tent blowing through a carbon scrubber and possibly another 4 inline fan at the bottom for intake.
Your grow room will therefore have two other fans one blowing air into the grow room and another blowing air out of the grow room.
This will avoid the build up of humidity and heat when you vent grow tent into attic.
It s not included on a tour of the house and isn t visible to neighbors.
The attic only has the soffit vents all around.
If you don t want your plants to breathe it over again there is a hack.
Some attics are difficult to get to.
Nobody else is going to go in your attic but you.
I was thinking of a portable or building a window ac unit box and exhausting the heat into the attic or maybe tap into the bathrooms fart fan exhaust.
No matter how hard you try some warm air coming out of the exhaust system will be still there in the room.
In an active intake the size of the intake hole does not matter.
