I recieved a real lesson in sealing off a room and air conditioners this past month that I would like to share
I bought a bunch if two part foam insulation and sealed off my room
Not understanding how my air conditioner worked I inadvertently cut off all my return air for this type of AC by totally cutting off any air infiltration to the room.
My humidity went from this
In a matter of hours and if I ran my dehumidifier in my newly sealed room my temps would soar to over 90° in a matter of minutes lol.
It took me four days of trouble shooting talking with some AC pros I know and I had figured out my problem…I had to get some return air to the air conditioner because it could no longer get it from inside the room.
After looking at that AC long and hard this is what I came up with. Wish I had some “before” pics but I don’t
First I took a Current Culture bucket and fabbed it to fit the back of the AC and accept 4" ducting
Then ran that ducting through the wall
Now this only took care of halfhalf of the return, I still had open vents
So from there I had to fab this round bucket to fit these corner vents
I got that done and the 4" ducting ran into it also
Looks like something out of an 80s sci fi movie now
But my environment is completely back tip normal or maybe even better now and the room is completely sealed
Got about two weeks till i harvest this one plant then will take out the DWC system for now, put my two plant autopot system in, a grow two plants about this size maybe a little bigger
Just thought I’d share.
