Hey y’all I’m planning to build a couple new cabinets and was about to go buy some plywood for the walls but thought ‘there must be an easier way’.
Is there something like black/white plastic that is legit 100% lightproof that I can use for the walls? I’ll still be building a wood frame for strength…
I’d get one of those premade tents, but these will be odd sizes to suit my space. Thanks for any tips!
Check out orca film… I used to use it to black out windows… It’s tougher than black and white poly too.
Looks cool, thanks! Is it totally lightproof? Like even with a thousand watter a couple feet away lightproof? 
Yes
I’d recommend the seam tape they make for it as well.or that aluminum tape. regular duct tape doesn’t seem to stick to it too well.
A buddy of mine back in the day used the black and white plastic Polly liner etc. and put a black plastic liner behind it. He said it didn’t leak, personally never saw it tho bud.
Doubling it up worked for him I guess.
I used gorilla duct tape and seems to work ok. Get the thicker mil orca and only has glow spots in an odd blem area here and there but that is all my walls are and totally lightproof.
Thanks all. Doubling up might be a good option, hard to find orca in Canada apparently and it’s $$$.
What are those premade grow tents made of?
Ya red (tuck) tape all the way for plastic. The newer blue stuff is pretty good too.
I use aluminum tape for all ducting stuff.
This is the one I’m using atm, they have all kinds of sizes
Ya those are great but I need really strange custom sizes sadly… I’ve used mylar in the past, but never the thick stuff like that, just the wrapping paper type mirror stuff. I wonder if it’s available in rolls.
I can vouch for the panda film/orca film. It completely blocks out the light.
You should be able to find it on amazon no problem for fairly cheap if you don’t have local hydro stores.
try looking for it under its alternate name - panda film.
Found this… its totally perfect:
Out of stock lol
lol great minds think alike
Ya panda film (black/white) is what I’ve always used. It’s unfortunately not totally lightproof.
Panda film definitely lets a bit of light through though, you can definitely see a 1000w through it.
Through the seams where you tape it or straight up through the film? I never experienced that when I used it.
I wonder do they come in different thickness? Maybe if they do a thicker sheet would help?
Ya through the film… maybe I’ve always bought the cheap stuff lol. I have a roll sitting here, I should do some tests. Maybe doubling it up as itokealot suggested would be the trick.
panda film is a generic name, so definitely possible the stuff you got before wasn’t up to the same standards as the version from my hydro store. I guess there may be more variability in this material than i thought, which could make it difficult to find a suitable version. If you can find it locally (usually for sale by the yard from a bulk ream of material), you could get a small piece to test with your lights before you make your full purchase.
experimenting with layering the material you already have may also work.
Ya I think that doubling it might be my solution. I’m very familiar with the stuff, I have a couple rolls of different types in my garage lol. I can’t say I’ve noticed much of a difference between types over the years.
Experiment time!
