I just don't understand people who want to run AC in the winter. Y'all like paying power bills or something?
The problems with bringing air that cold into the room are, in no particular order, wild temperature swings, wild humidity swings, cold spots and of course where the exhaust goes.
4kW is too much for ambient cooling. It's almost enough to heat your house with. Your best move is to move the heat, if not the air itself, into your home. A closed loop air to air exchanger would do it.
Next question; how will you get adequate CO2 in there?
Finally, how do you plan to manage humidity and keep the temperature from dropping too much during lights off?

That’s why he would use a thermostat, if he used a fan control he can control the speed of air coming in.

Gotta be real careful about that in terms of inlet air placement, thermostat placement and air movement.

But I get what you are saying about using the heat within the house. I do it and it works for me in my climate

I get enough free heat from 10kW running 24 hours a day (2 flower rooms on a flip) to heat a 1300 sqft home until it hits -5F outside and it's windy. Didn't have to run the furnace last year except at harvest.
I think thats just his way, shit he even argues with me.

great questions, i do appreciate all the help i can get. can you tell me more about air from the lights to an air exchanger i dont have an air exchanger on this building usually see those on newer homes could you explain how that works?
so the best options it would seem is
-a closed loop circulating the heat throughout the house
-4" duct on a thermostat pulling cold air in on a thermostat / (i imagine fresh c02 would come inside at the same time alternatively could get a c02 tank)
-for humidity i have a dehumidifier that i can hook directly to a sump pit that will pump to the waste water for the building im not sure if its large enough may need a larger one.
im not to worried about that i had a hvac guy doing central air for the house he was going to setup the minisplit for me but i ended up doing that i showed him the room im building i talked about the split not be able to run in the winter he had a similar suggestion to yours just he wanted to use a motorized damper rather than one on a spring i think the location for it will be fine but i can always check with him if im unsure.

And here I thought it was just friendly debate...

House must be well insulated. 10kw around the clock would keep it warm. 10-20kw is what can heat most homes. I’m a licensed HVAC contractor.

You'd love what I'm doing; I have a system for cooling commercial grow facilities that doesn't use AC except for dehuey- and when it gets cold enough out, they don't have to run either!

Going from my experience when venting out the stink it goes 24/7 so my cold air return is always open.I have it far away from my room so the cold air mixes with bsmt air to warm up a bit.
Im now searching for a vent hood to try the closed loop thing to save some heat thanks to this thread.
cheers!

I fought through all of the above for cooling in deep cold winter environments. Last year I took the plunge and invested in a water chiller system for winter months. I have a 3 ton air to water heat exchanger that chills 35 gallon reservoir of water/glycol mix. Then I have two separate one ton air handlers in flower that are chilled by a separate pump from the chilled reservoir. Both air handlers are controlled by one of those cheap thermostats that you can plug a 120 plug directly into. Outside air handler is controlled by a ranko temp controller that uses a probe directly in the res. Water pumps run continuously and the air handler fans fire up when called for. Pumps are like .5 amps and slightly higher for fans, so it’s very economical to run but expensive to set up and get started. To cool my 4K room it cost around 3 grand but... it’s all relative.
I bought everything from Chillx and I can’t say enough about the customer service as well as the quality of the equipment
It’s not for everyone but it works amazing for me.

this sounds very effective, is that 3000 US? i went on there website couldnt make heads or tails of the stuff i was looking at are you able to send me direct links from there website on what i would need to purchase, a photo of how this works would be so helpful. are all pieces of equipment located inside the building or is there anything that is outside just having a hard time picturing it in my head since i've never seen one of these. how much floor space will i need for this equipment as well.
