Sealed grow room as cheap as possible.

I have an uninsulated/unfinished detached garage that I am running some tents in. I’m near the ocean so my temperature rarely falls outside of 49F-85F year round. …Everything was going great until a heat wave rolled in. My tents shot above 90F for 3 days while in week 6 of flower. I’m now battling plants shooting out nanners from the stress.

With summer on its way I need to create a insulated room. I rent and need to keep cost as low as possible. Luckily I have been collecting grow equipment so I already own:

Large dehumidifier, humidifier, 10k btu dual hose A/C with dehumidifier, 14” in-line fan w/ huge carbon scrubber, 3 16” oscillating fans, a CO2 monitor, humidity controller, 3 6” inlines, 4” inline fan, and for Lights 2-HLG v2 Rspecs 550, and one 650r spec.

Just to keep things interesting I have limited power to work with since it’s an old house. I’m currently in the process of running another 15amp line to the garage from the panel. I cannot go larger on the breaker without going passed 85% capacity on the main breaker. So I have a dedicated 15amp 120V line to work with in addition to a shared 15amp line - so I need to keep it under a 10amp load for safety on the shared line.

Garage build out-

My original plan is to build 2 walls off the northern facing corner of my garage. Since I already own a co2 controller I plan on making this a sealed room since all I’m missing is a tank and regulator. The room size is going to be 6ftx6ftx8ft-height. I was planning on sticking the two 550’s in there so they cover 6ftx4ft. the other 2 feet will house the equipment. Let me know if I should set it up differently.

I was going to frame out the two walls and add a door. I was planning on doing dry wall with foam board insulation sealed in-between the wall. As started adding up the material cost it got to around $500. Could I lower this cost?

I started toying around with the idea of just ditching the drywall and just using foam board. This lowered my cost dramatically. The 1/2” insulated foam board is only $8.

I understand this will make hanging stuff a pain. But I would just work off the studs. I don’t need the structure to last forever, as I will probably tear it down when if I move.

Thoughts on what I’m attempting?

Wow.

The word "Cheap" and Grow-Room Build do not go together around these parts there pardner.
There is however 2 inch foam-board at Home De Pot. It has Pink Panther on it. Those are 4 x 8 I believe. I picked up two of them to enclose what was porch windows of this old house. Why no one ever closed off the useless windows I just don't know but I will!

Also on running your line to the garage. I would fugetaboutit and run a sub-panel. You need to run a GFI breaker if you do that. That is Per-NEC 2020. It's a new requirement.

THEN AGAIN : You are a renter and you are rewiring your rental and not doing it to NEC 2020? Something is wrong with that picture.
Have you talked to the owner about having him put in a sub-panel you can use? You never know he might be cool with that instead of hacking his electric. You can always offer to pay. If not and there is a fire their insurance would be VOID and you would have to pay for the Rental Damage.

No such thing as Cheap or free-lunch-ish when if come to a build out in my opinion.

I don't know of any properly built/spec'd sealed grow room that can run off of 10 Amps.

It’s nothing crazy. It’s just a 4x9 room I put up in my garage. It has two 15 amp circuits in the room. 1 dedicated 15 amp for the lights and Dehum. The other 15 amps shares with my house and that has the A/C on it.

it works and gets the job done. It’s not perfect but it’s temporary and i will tear it down when I move.
