Off-gassing and toxicity of building materials in CEA

[Catatafish]

Im in the middle of a build out and at the point of needing some caulk/sealants. Wondering what is the best route to go with thats available at the local hd/lowes/ace so i dont make the room too toxic too use.

I have found ecobond but its going to take longer than i really want to get here.

From what i understand great stuff and most caulks are pretty nasty off-gassers.


Any advice on primers/paints that are good too would be appreciated I have some bear ultra premium plus laying around already that i would like to use if it wont create problems.

Fwiw, I used great stuff throughout both my veg an flower rooms and have never had any issues. I let it dry completely and aired out the rooms before I put any plants in. Same for my partners, we all use Great Stuff without issues...

Lol A/L... i should of asked. Didnt want you to get sick of me

How long does it take to air our room .... couple days or till you notice smell gone?

Only reason im asking is i need to get stuff in there asap as some have some serious vigor apparently and shot up on me quickly so i dont want them to get too big. Plus my veg room is in a closet that is in same room...dont want all those to keel over while i do it


Thanks.

I only waited a few hours. Sorry it took so long to answer back, I'm on vacation in the Mediterranean right now and theirs a 6 hr time diff.

 

[Catatafish]

Sweet. Have fun on vacation, sounds nice! NP, i was at work anyways.

Perhaps some aquarium silicone? Are you worried about off gassing when dried and cured or right after use?

hey Catatafish, I wouldn't sweat it very much for caulks and sealants. They will set up quickly and the smell will dissipate fine on its own. I used literally thousands of dollars worth on green glue, accoustic sealant, and various brands of caulks and sealants (fire caulk, etc..) I have zero off gas issues, there are none in my room and I used a shit load of sealants....

there are reported issues with some foam sealants though like good stuff but I used it in a couple of places where the application made sense.

Get a good filtration mask, the kind with the activated carbon etc... and wear it when you are working, ventilate the area and I would not expect issues.

I have a good filtration mask and was planning on wearing it. Couple hours of poison smell is ok Hell even a day or two isnt a big deal.

I was reading else wear people losing genetics up to 1-2 months afterwards in some of the threads on here so thats what had me worried.

I have a window inside the enclosure that i will open and put a fan by to help clear the smell. I seal the window last i guess.

I only have 1 wall i built so im guessing i will probably be using a lot less than some of the other folks did and shouldnt have much to worry about. I just divided 1/3 off an existing room essentially so the other 3 walls wont be touched other than the window sealing.
