Diy grow box vs grow tent (which will hold the smell in better?)

For a 4x4 grow will a plywood box with plastic “vapor shield” layer and calking hold the smell in better than a tent?
Or does it all come down to using a fan and filter with the right specs and negative air pressure?

Fan and filter is a growers best friend when stealth is a main concern. Also I like tents. Easier to put away if something ever comes up.

I feel for the time and effort tents are probably a better option as all you need is negative pressure and you can guarantee no smell will leak as long as your filter and fan is setup correctly.

As someone who grows in both, i prefer the wooden cab, quieter, no sucking in from negative pressure & no potential pin-hole leaks, heavy lights all day etc.. Just need to make sure your floor is coated/sprayed with something water-resistant.

Hands down a tent is much easier to setup, and a zipper works better than a large swinging door, if you don't have wood working experience, a tent is probably an easier option for you.

Now that I own a house and have the space I might consider building a wooden box, I'm sure I'd be great at it since I've been handling wood for as long as I can remember. :hump:

If you doing the negative pressure thingie and you want to stop the tent walls from being sucking in, make you some tent bows. A guy at one of the local nurseries makes them for all his friends. They're just a piece of bar-stock aluminum that is bent slightly outward like "Bow", and on the ends it looks like its 5/8 rubber hose cut in half, and the bar-stock is epoxied to the hose with some of that fuzzy automotive tape, (the cheap mans carbon fiber tape). And each end presses up against the tents frame so you can easily raise or lower them out of the way when you need to work in there, you use 2 on each wall, and it completely stops the tent walls from blocking light to those buds that always seem to get squished from the tents walls getting sucked in! And if you don't want to go to those extremes, you can always use curtain rods, but they don't work as well as using a slightly bow out 1 inch bar-stock aluminum does!

A PVC frame works pretty good at least in the smaller sized tents. I ran a 4 x 4 with one I built for drying just to see how it would do and seemed more than adequate and much cheaper.

Same here, i am a pretty hardcore fabricator regarding fiberglass & various types of wood, my only regret is using wood glue on my first cab, im the type of guy who uses wood glue and pocket joints on everything but never again will i glue a cab together as it will pretty much need to be destroyed upon removal, at least with anything over 2x2.

I'd like to build some sort of something that I could leave outside that would be water tight and with ventilation in it for a early season light dep.

Yeah, the PVC thing sounds even better, I just saw what that guy did one day and thought it was pretty slick....

Cedar or white oak & tightbond ultimate would do the job nicely. Might be pricey but with minimal amount of internal bracing and oil based paint, it will last you a decade easy.

My family has pretty much cornered the market in manufacturing industrial walk in coolers, we built the worlds largest 12 football fields by 14 football fields. I have been thinking of using that same idea that we use for our walk in coolers / freezers and turning them into grow room kits, as lots of people have shown a lot of interest, we use a patterned shiplap panel design, it has a fiberglass of aluminum sheeting over a plywood sandwich that has 2 to 12 inches of high r value vulcanized polystyrene core, and we use patterned internal camelot locks to lock it all together. I think that would go over pretty good for making grow rooms because you could easily setup or disassemble one anywhere on the fly!

Sounds complicated but good. Only imagine what the instructions would be like.

I've been putting up steel buildings for work. A few are freezer buildings, distribution hubs for food. I keep seeing those panel leftovers and how good, quiet, and sealed a room would be made from that!
I hear its pricey!
