5X Gavita 750w DE Build

[kigy]

Whats up everyone!

I have a new 22Lx9Wx9H area to play with and am going to run 5 Gavita 750w DE setups in a single row mainly because of local wattage restrictions. I will be using a 24k BTU mini split for cooling.

What I'm concerned about is the exterior wall is shared with a neighbor's backyard and I'm fairly certain a secondary barrier is needed to prevent the odor from migrating through the exterior wall, even with a 10" vortex/carbon filter combo inside the room.

What are your experiences with DIY heavy duty grow tents (made with metal tubing or SCH 80 PVC) or is it best to just construct a "room-in-side-a-room" with wood 2x4s and drywall?

The floor is a slightly sloped concrete slab so I'll need to account for a minor grade during construction. Set up/construction and disassembly are certainly important factors.

If you're running at enough negative pressure air will only be coming in through that flimsy wall, but safety third.
Just brainstorming, have you considered ridged foam insulation? You might be able to avoid framing it out. Just cut to size, attach with a few screws and foil tape the seams.
Lots of people like tents, I don't have any experience, but they are easy to put together and take down.

after growing in built rooms for a few years, i have recently been put in a position where i had no choice but to veg some plants in a tent, I don't understand how tents are a permanent option. Growing in a tent is very cramped for me, if this setup will be long term i would look into a built room. also if you go rigid insulation look into sheathing tape for the seams, the foil tape peels back over time.

Have you guys had good experience using rigid foam insulation as walls? I've heard people have some issues with off gassing that makes me hesitant. I am thinking my best course of action is to frame the room with 2x4s then use OSB board as walls instead of drywall.

I will be posting pics as the build progresses! Thanks again to everyone to has replied here and by PM

i have had first hand experience with r-max insulation off gassing. panda film over the rigid or run the room vented.

OSB, regular insulation, and panda is safer

if you don't like outgassing I'd use plywood instead of OSB. Plywood has almost no outgassing, OSB outgasses VOC's for 10+ years.

Thanks for chiming in skinner, Good to know.

Nice, those lights are a good choice, get the master controller and you're all set! First with enough negative pressure your air/ odors aren't going to have a choice they will obey the vortex rules of gravitational air force as long as you have a proper size fan and filter. If you have the money go for 1 layer of mould proof gyprock inside and 1 layer fire code gyprock outside once you putty you make it pretty much air tight cover or paint inside with something reflective. Or if you're on a tight budget like me use panda and 1x3 lumber and 2x4 to quickly frame your room. I like this option because it's also quick and easy to take apart if needed.

This is all great info, thanks everyone!

Final dimensions of the room were 22x8x8. The garage is only 24x12x9 so building this room required some careful planning lol.

2 ton mini split sealed room with 60amp subpanel. This time I made sure I had outlets every 4 feet (running extension cords everywhere is a pain in the ass). Electrical wiring is finished. First run in this room will be all Dark Hearts Girl Scout Cookies. Will finish setting up the Gavitas and master controller soon and will post more pics.

Wiring coming through the access hatch was later piped through a 3" PVC through the roof and to the main panel. I can provide pictures if anyone wants but I think it makes it look a lot cleaner.
