Shoulder I Drywall The Room?

I like to be able to hang stuff anywhere I want so my walls are osb with panda (inside). Ceiling is drywall over osb. Outside of the room is drywall and finished. All in a basement. I also use the expensive fire core stuff on the ceiling.

I use drywall and attach a rigid foam boad to it but the foam board I use has a reflective matireal as part of it so you don't need panda film, but if you already have panda film and it is going to be a perminant room than just drwall it and use the panda you could always take down the panda and put up foam board or mylar another time just be sure it's going to be the final room before you drywall it. I recently moved into a new room and it is built into my house so that you can't tell its their with drywall insulation and reflective bubble insulation on the inside with a hidden top secret book case door on the outside with drywall and paneling to match the existing room. we are still talking about a 3x3 room right i assume 3x3x8 I run a 3x7x8, 3x3 for flower and on the other end I have a veg cabinet works out nice

Was thinking drywall to make a nice solid room and reduce sound. Have made a box to house the inline, with insulated ducting. Would be using insulation board be better?
Found this brand, DuroFoam EPS rigid insulation. Would still be putting panda on the foam.

Which one would be best to go with?

1/FOAMULAR C-200 Extruded Polystyrene Rigid Insulation

2/DuroFoam EPS Rigid Insulation

3/SHEETROCK Firecode Core Drywall Gypsum Panel Tapered Edge

They all cost approx. the same.


*one side question also related, on safety. Made a box to hold a 4" inline, out of some type of board. It was wooden and had a sanded finish, a rectangle in shape, 96inch x 12inch. Is this box safe? I don't feel the fan or even the ballast create much heat at all. The ballast is just slightest warm, at its hottest, fan is fine.*

I would go with whichever insulation doesn't make a fucking mess when you cut it... Like the foil back styrofoam crap


Your box is totally safe. The air moving through the fan will keep it cool. Mount the fan in the box with rubber grommets to cancel vibration. Also seal all the holes with caulk or liquid nails. You will be amazed at how quiet it is!

Thanks, that's what I needed to know! Safety first .

Never understood this vibration noise thing. The fan doesn't seem to have even the slightest bit of vibration?? Not on the floor. Not when hung on a chain! (with bungee's as extra support). Tested in the box and it is about 40% quieter, no vibration? Although the fan fit's snug in the box width wise, with a little space around the in/out sides.

Good idea with sealing it. Was going to use hot glue? lol.... maybe a clauk would be better .

Not trying to start a pissing match but I can't for the life of me figure out why people want to drywall grow rooms. The ONLY advantage to drywall is sound attenuation. ANd if that is your goal you need to grab the 5/8 stuff.

Drywall is heavy as hell, messy, is a pain in the ass to get rid of if you take your room down, it harbors mold, it has to be painted to be reflective, it make studs hard to find, and odors pass right through it.

Panda film or as someone said above, rigid board insulation.

This.

Use the highest density anti-fungal material you can. 3/16" hardboard(Masonite without the holes) would work fabulously. Most people don't understand that even an air gap of 1" has an R-factor of 1. In case you don't know what that means, an air gap(sealed) is "free" insulation.
Dry wall is porous, so it will absorb anything that comes near it (ever tried getting the smoke smell out of a house?) Even painted, the material will still "breathe". It is quite messy as well, and heavy per sq.ft.
You can put your film over any material you want, some people use it for their only exterior wall(over a wooden frame), or you can "finish" it and cover the walls with a film (or paint).

Its funny to me that people think drywall is an airtight material.

djwimbo.. you ever use the exterior drywall product, shit, can't remember the name, I think its called xrock>?

WE have a new grow room in an ICF built basement and we need to fireproof the walls as a hot bulb that touches the ICF will melt the blocks pretty damn quick.

I'm not familiar with using that product, I think I've seen it around though. I usually stay as far away from drywall issues as I can, aside from spackling/sanding before painting.

I like building things that are built to code and will last. Therefore, drywall, tape, mud, seal and paint with exterior grade paint. Lots of plugs on a dedicated circuits in a sub panel. No extension chords. Install good ventalation to the outside. Drain in the floor.


Drywall is fire resistant, that is why it is used. Also, drywall is cheap and easy to cut and hang. Just use a box cutter and a straight edge. Score one side and bend away from the score line. It will snap leaving very little dust. Hit that shit with a saw and you'll have a big mess! Just keep a shop vac on hand.


If you don't want to make a mess, buy your weed.

"Build to code" LOL. As if drywall is part of the code. FYI, interior walls... ergo.. the walls you would be using to construct a grow room.. DO NOT have to be fire rated. MY panda film room is entirely to code. Proper circuits, etc.

If you want to use drywall, then by all means use drywall then. I'm just saying there are cheaper, easier, and faster ways to skin a cat. I'll concentrate on growing weed. You can concentrate on building a "real" grow room. LOL.
