Heat greenhouse from mini split exhaust????

[topset1976]

Hello I have a 40x20 greenhouse full of 15 flowering monsters that have about a month to go. I live in Portland OR and it will start getting cool in late sept. Last year I had to deal with some bud rot and stem rot. I want to avoid all that so I have a big dehumidifier in there now as well as a large greenhouse exhaust fan and lots of fans moving air around inside.

My question is I also grow in my shop that is next to the greenhouse. I have a 36k btu mini spit and the exhaust for it is maybe 3 feet from my greenhouse. The lights only come on at night so that's when the exhaust is warm. I was wondering if it would help if i pumped the exhaust from the mini split into the greenhouse. it would warm the greenhouse at night and wouldn't cost me any more electricity. What do you guys think? I know the mini split acts as a dehumidifier so I was wondering if the exhaust is very humid? There is a tube that emptied out of the mini split the water that the mini split gets from the air and it exits outside so maybe the exhaust isn't as humid as I may think? Anyone know if this is a good idea or not so much? thanks

btw i was going to post this in the greenhouse section but it said I didn't have access for some reason?

Put a cheap temp/humidity gauge in front of it in a tube or something and check it out. That's all I got...

The exhausted air from your outdoor unit is only as humid as the air outside...And the humidity you remove from your grow room, is what drains out of your indoor unit in the form of condensate

Sounds like a pretty good idea. Bungle is right about the air only being as humid as the outdoor air it is sucking in. The humidity inside with the air handler is not transferred thru the Freon to outside unit.

Question is, should you place the entire outdoor unit in the greenhouse, where it is using the air in greenhouse to also suck into unit? Or have it sucking outdoor air into the unit and expelling it into greenhouse? Hmmmmmm...

I can't put the exhaust panel from the mini split into the greehouse since it is already hooked up and would be a pain to move. It doesn't suck any air in it only blows warm air out. Inside my grow room the ac blower on the wall sucks air in from inside the room I believe. All I want to do is cut a 3'x3' square in the wall of my greenhouse and make a tunnel from the exhaust to the greenhouse so the warm air goes into the greenhouse. I'll put a temp and humidly monitor in front of the exhaust to see how humid it is. thanks
