AC Selection for Veg Room With CO2

Upgraded my veg room to LEC315 x2, in addition to some T5’s for clones etc. I would like to run co2 in this room. A mini split is out of the equation because I have no more blocks on my panel. I have plenty of amperage left on the outlets that feed the room to accommodate, however. I actually have two feed lines feeding the room. One is dedicated and the other is shared with my drying and curing room because there isn’t a large load on that circuit. The room is well constructed, and sealed exceptionally well as well as insulated on the walls that back up to the garage space. Shared walls with flower rooms are not insulated. It’s dimensions are 6’6” x 11’

I have been ruminating for weeks on what kind of AC I want to run. Leaving the door cracked with a fan won’t be a viable option as the temperatures start to heat up over the next month. The dual hose portables are known to work well in sealed environments, and I can pick up a 10k BTU for 250 locally at a hydro store. That’s option 1. Option 2 is a window unit or through the wall unit. I have no windows. It’s OSB and 2x4 construction, and is standard 3.5” gap between interior and exterior sheathing. I am leaning towards window or through the wall units because I don’t need 10k BTU for this room, and don’t want to expend the amperage. Plus the wall mounted unit will not take up floor space, which is very valuable to me in this room as I take my veg game seriously. A 6000 BTU window or through the wall unit would be plenty of cooling. Plus, I’d prefer to have the AC running more often for dehumidification purposes. Will a window unit work with my wall thickness, or do I need to go with a sleeved through the wall unit (which are unjustifiably marked up IMO)? If I install one of these units, what’s the chance of co2 leakage? They simply recirculate the room air, correct? I’m not overly concerned about odor, as this is just a veg room and my operation is fully legitimate anyways.

Any help is appreciated, and photos are always encouraged.

A window unit could easily be mounted in your wall. I'm running a 6k window shaker in a 4x8x8 room. Veg and flower. Went with this one because it's digital with remote. I also run a dehumidifier.

The Remote allows me to adjust AC settings from outside the room.

Then I found this lil wifi gem. Now I have my settings scheduled and automated. Anywhere anytime AC access from smartphone.

Just FYI - Many breaker panels are compatible with space saver breakers, you could use a few of these on existing 120v feeds to open up a few spaces for a double pole 240v feed that could be used for a minisplit. That said a minisplit is probably overkill for your cooling needs. I have a ceiling mount minisplit, thats a big space saver for me, it can also be wall mounted.

Some of the nicer portables don't need a condensate drain line so you may wanna look for one like that.

As far as a windowshaker they make casement units that are designed to be installed thru a wall between studs.

Make sure to get a unit that will restart after a power outage.

Anyways I hope those thoughts help.

The issue I’m finding with a set up like this is that window units don’t have enough of a frame gap between the front lip and the vents on the side of the unit. Yours is mounted to a door - not a 4.5 inch wall. Big difference in thickness.

I hear ya. May need a casement unit.

In my one experience. A Window unit mounted with the face place flush with the inside wall, outside vents slots were not blocked.

Hope you find a perfect setup.
