Wife is pissed... last grow wreaked the whole house of some dank.

Wifes solution - quit growing

My solution - seal er up and grow more.

I'm growing in a room i built in the basement ~7'x10' and want to have a spray foam company come in and spray the walls and ceiling. I caulked the bottom perimeter and painted redguard about 5'' on the floors and all the way up the drywall and studs on the inside of the room... why so much idk maybe it'll help maybe it won't but it can't hurt.

Anyways, my question before i spend 2k on this. Has anyone done this and if so did it cut down a lot if not all the smell? I am currently ventilating directly outside through a dryer vent in the wall with aci filter (not too worried about the outside smell) and also running a 4'' aci filter in the room to scrub the air.

They would use a closed cell spray foam.

After the spray foam I plan on encasing the room with panda film as air tight as possible as well.. It probably won't be perfect as this is what i did and it stunk in the home but helps with lighting and also maybe an extra layer of protection on smell?

Also, recommendation are more than welcome!

It's got to help. It's used in new construction a lot now as it;s a good vapor barrier and to stop air infiltration. Do you think some odors could be leaking out when opening and closing your door? Maybe have two doors and create a rudimentary airlock between.

Filtration, buddy, lots more of it.

+ 1, scrubb the air of the growspace thru some type of filter, carbon should do it. Filter capacity should be larger than the fan for really slowly pulling air thru the filter. It also helps if there are airborne pathogens

People can still smell it with a filter you just get noseblind to it. Harvesting is going to blast the place, always does for me unless I exaust outside and use the same concept but turn the whole 10’x10’ room into a negative air pressure tent.

I cant do this in summer time though, warms up the entire house. Just a thought 2k sounds like a lot, I blew over a grand I just gave away in equipment. Id try to get all input you can before spending that. To me smell is the easiest thing to control.

Just need negative air pressure works like a charm. No matter how many holes in the tent or space, it will suck through them. Smell cant escape. I dont think air tighting the place will do anything. Need good enough ventilation.

A 6” s line vortex can vent my whole room. But even the carbon filtered air still smells but its harder to narrow down where its coming from when outside. Venting back into home the whole home will still smell to sensative non users. My hvac guy said hell yea I smell it. I thought he was lying.

I vent mine up into the attic above my neighbors noses. Haven't had any mold problems over the last 15 years.

Me too. I tried it once in the winter without a filter. I could catch occasional whiffs of it outside so I know others would probably be able to smell it easier than me. The filter went right back on.
