For like the 6th time SOUND DOES NOT MATTER IN MY CASE.

I thank you all for sharing information but I do not need it.

@countrypickle wow this corrugated plastic cardboard would save me so much hassle and a few bucks. Best tip I've got so far!
I'm surprised I haven't heard of anyone else using this in their rooms.

One more thing @countrypickle this won't be outside exposed to elements it's in a covered and zipped up portable garage.

The way you worded I can tell if you mean to put the plastic sheets on top of the foam boards on the inside or on top of the OSB on the outside. Because the outside won't matter I'm just trying to find a pannal for the inside.
Can this plastic sheet be used for that? Is it going to hold up to the lights given it will be covered by panda film.

Here is my final advice. This would be the cheapest but yet effective way of doing it. Build your 2" x 4" frames, sheet one side with OSB, Install batt type insulation (fiberglass, stonewool, denim) staple 6mil vapor barrier to the studs to cover insulation and use sheathing tape to seal any seams, sheet over that with more OSB and now you have a well insulated wall that can be covered with mylar or just painted white. If your going to paint it you could always use plywood on the inside rather then OSB for a smoother finish but will be more expensive or you could always go the corrugated plastic route if your not wanting to secure anything to the walls. Corrugated plastic will be around the same cost as plywood. Plywood or corrugated plastic will be about 2 to 3 times the cost of OSB.

Might as well just build a shed.

How else would you expect to keep the elements out & be able to control temp/humidity inside. He is trying to build a room where he would like to control the environment inside. TBH maybe a shed is a better idea as the portable garage/shed this is going inside may cause other issues. Cheap out now and you will be cursing when the plants start to flower and you have all kinds of issues lol

I've prepared for issues to arise, climate, humidity, pests, deficiency, power outage, equipment breaking, mold etc. these will be in the area for 2 grows then be moving into a garage with more stable conditions and less worries.

It would be a lot easier for you to work the other way around.. build the frame... osb the inside(paint) to make ur box.. insualte the outside ...wrap in a plastic wrap (seal)
I work with an insulating company( definetly no super taught professional by no means) We do all blown in types,batts,foams,vap barrier,
.The biggest thing I find most ppl dont understand is the temp difference between outside and inside the"envelope". hot inside,cold outside.. or viceversa.. can quickly created condensation in any area with no circulation for air.and sometimes sealing it too tight can make it worse( picture those hippy forrest in a jar things..self sustaining)..
Id keep pouros(spelling) construction materials closest to the air..and non permeable (Thats the word lol) items closer to the heat/moisture..

Can this plastic sheet be used for that? Is it going to hold up to the lights given it will be covered by panda film.[/QUOTE]
yes and yes I used it in a room I had...(have to reinvent this year.. kids getting too big as is thier curiousity....).
best thing about it is that every 6 mtnhs to a year.. take it down soak in cleaner.. put it back up.. u can get it in diffrent sizes or like I said.. just wait till elections are over.. they'll be throwing them out like mad..thats when I save mine... use em twice clean em once..toss em just befre next election time. thier great for cleaning...
I was thinking of the outside of the "box" but it can be used on inside as well .Only issue is close to the lamp.. paint the cieling . If u got osb on the inside already..cheaper with paint. If only for a few grows... I'd stick with the "kiss" method ( keep it simple stupid). Like a previous poster said.. build a box.. batts vapbarrier on outside. seal the edges.. done and done. F.O.F function over fashion. when u relocate to your permanet place.... build ur shed,tent,garage, underground walapini ( google it ;) ) wutever the heck u want... Oh and make sure u refer back to here about soundproofing it too when its ready. lol j/k I've learned a lot about how to guriella my next room (quitely) now.
..and ignore the spelling..........smoked a biggun while reading up... happy weekend ;)

Avoiding moisture build up on the outside would be awesome. Would any kind of plastic vapor barrier work for this.

I found this at Home Depot real cheap,
Silicone Vapor Shield Underlayment for Wood Floors 6 mil

If someone can answer my question in regard to @countrypickle idea of sealing the outside of my box I would be grateful. I will be buying my supplies come Tuesday for this build.
When you have colder outside temperatures I think you will get condensation in the walls from the warm indoor air permeating through the building structure and meeting the colder outside temps. But that's just an educated guess.

Since summer will have condensation on the outside and winter condensation on the inside.
Would it be smart to put a vapor barrier on the outside, and then one on the inside as well.
Correct me if I'm wrong is panda film 6 mil considered a vapor barrier.

Normally in building science it's agreed that the placement of the vapor barrier within the wall assembly doesn't matter in regards to which side of the insulation it's placed. But given that we prefer negative pressure inside our growing space and all the issues covered in the article I linked, I think depending on your outside environment that having the vapor barrier on the outside might be beneficial. All that being said the only true way to find out is through testing and measuring the conditions that you will be exposed to. All the mold resistant building materials won't do jack if the conditions are right, hell our bodies sluff off millions of mold spores & bacteria every day. I guess my point is based on budget I wouldn't get to crazy worried about it cause rebuilding parts and correcting issues might be cheaper in the long run than going hog wild and over budget on gestamating. Warning I'm high so this may all sound stupid in 3 hours.
