to insulate or not to insulate, that is the question

[doctor.dank]

I'm building some sealed rooms and I want some opinions on if it would be more energy efficient to insulate or not to insulate. I'm going to run co2 with temps between 82 and 84 lights on and 75 lights off. I live in a cold climate where the average tenp in July is 75 degrees. I am running mini splits that will cool during lights on and have to heat during lights off. During the winter I'm probably going to shut off the cooling and just run active air exchange. Since outsidemy room it will likely always be colder than 82 degrees it would seem beneficial to not insulate however I'm thinking it might end up hurting me in the grand scheme of things due to the cost of keeping it heated lights off. Any thoughts would be appreciated!

Always insulate, easier to control temperature when fluctuations are minimal.

With putting in the amount of effort it takes to build a room bro would always be best to do it right insulate if you can

Insulate with consideration of increasing humidity levels in peak winter

Thanks everyone! I wasnt trying to cheap out by not insulating I was just wondering if it would be more efficient to not insulate because of my ambient temps. But clearly I should insulate and thats what I'll do. Thanks again

Can't recommend Roxul insulation enough if you can get your hands on some.

I dont think mold will be a problem for me. I plan on using MR bathroom grade sheetrock with NO VOC mold resistant latex paint. Then it will be covered with orca film and completely sealed, so in theory no moisture will get behind the orca film

the only problem I have with those insulation boards is they are known for off gassing and can cause problems in a sealed room which is why im going with no voc (no offgassing) latex paint over mold resistant sheetrock. Going to put insulation inbetween the studs behind the sheetrock.
