Yea they explained its just not the best system and we were asking for too low temps it can handle. My grow now isnt effecting it its doing a good job as is. It was however effecting it by venting out and no replacement air.
That part I dont get my mind goes blank thinking what happens in a vacuum. Like can humid aire pockets form in a vacuum? I turned all my canopy fans off its just wind burning plants. Making lower leavs fall right off.
Anyway. The part I do get is itll suck in heat through the house cracks etc. I just need to be more hands on dialing enviorment maybe get a inkbird or aci kit.
Its much better setting dehuey to 50%. 3/4 a year will be easy just block heat vent and allow grow heat to heat room. Besides I vented out since january and no issues with heat. It appearently is easier to heat a house.
Everything I rambled came up including ac systems just being finicky not much coolng power as youd expect. Id ask how to improve my grow but they dont seem to want anything to do with it or at least this new guy.
I dont think its worth the money and effort my grow is fine the house is fine I can finally rest.
