Consider adding CO2 to the room and see how that goes. If it is a sealed room it wont be too expensive as long as people using the washer dryer keep he door closed. I will be honest I wasnt thrilled with the results when I added C02 to my room.
The previous owners had a litter box in there and probably a dog that thought it was a buffet
Interesting idea CPW never crossed my mind. Yeah room is sealed tight doesn’t get opened much damn near a time capsule. With 7 different strains I think I will find out soon which ones likes tropical climates and which don’t. Is C02 expensive? Thanks CPW
I dont think its too bad once the area is filled, one thing I didnt care for is you need to keep the ambient temps up around 90 deg's for it to be beneficial and if your C02 runs out for a few days while your out of town your going to have foxtails to deal with, and you will end up doing all the laundry on your own.
I think If I were you I would buy a Louvered Dryer Vent Hood, thats how I pump the air out of my basement growing area. Leave the filter where you have it and pipe the air to the vent and put the fan between the filter and the vent
