Gregor Right on, you are the frigging man 🤘🤘

Oh man, I wish I could understand but it's best I not even "make" myself learn mathematics.  Tbh seem to always come up with different numbers.  47% seems pretty high. Shit has been pretty well though.  

Thanks to some pretty cool people-Pretty soon I'll have some rye berries again (not an option for a long time now) and they are a grain that whatever it is I do (RR style pretty much) they are great. 

Sean MWell I guess if your making a structure with pvc pipe you might find it hard to attach the Coloplast,  I'm trying to think of how I'd do it and I guess Tape and a lot of it.  The 3M stuff is expensive.  Wicked useful.  You'd basically be making a tent somehow. If I was you I'd just get cheap wood, paint it and screw the Coloplast and then use tape.  I bet PVC and it's fittings are pretty expensive.  Like I'd love to make one of those PVC racks but the corners and other shit are like $3 a piece. A piece of 2x4 is $3. If you don't need your rooms to be "structural" and hold up anything maybe you'llsucceedwith a cool light structure.  (Coloplast is light so that's nothing) 

Also thanks for the cold spawn padding last time. That foam fits Perfectly in my tote that I bring homemade blocks to the Farm safely-er. Thanks 

Right on, that must be nice an easy to clean.

I'm very close to having an RO water system at my place. Epoxy is so nice, frigging like so expensive tho. I just painted my cement floor with multiple chemically crazy primers and then a nice clear coat. About half the cost of Epoxy.  Most my problem had to be the shitty cement floor and the well water & or/possibly-also the humidity system which is a tote and just not great for more than a week without thorough cleaning. 

I should take pictures of the "oh shits" but I've non currently. It's looked like little bits of wants to be mushrooms growing on top of mostly the Black pearls but a few trumpets too.  So farm cleaning has helped so probably yeah, bacteria ish. 

Tim Green steel studs are used with steel stud Track. So you'll lay out your wall dimensions nice a square then either Ramset or i would suggest Always is to pre drill and fasten the track with Tapcons.   If your pad is 6" or 8" a ram set is quicker.  If your pad is a little 4" rat slab then use a drill and tap on so as not to Crack your pad. 

Then once the track is down you can place your studs 16" or 2" is what I did as is not a structural build just some walls.  Roofs get heavy though so I would keep at least 2" between studs.

It's all little self tappers so have the proper screws and length (small)

Is it outside/new slab & build.   I used Steel studs for mine (about half of your dimensions).  I actually searched around Facebook market place and found more than enough studs for half price too btw. My walls and ceilings are just foam board inside the steel frame. Easy, rot proof

I can't wait to try these.  Sold out like instantly. 

Ok right on. I'm pretty sure they are Sakato ones (round filter). They feel real thin. 

Tyleryou could even put some UV lights up to constantly sterilize your Attic plenum space if it's nothing more than a fresh air cooling station. I like the UV sterilizer lamps and have one on a timer  where my AC blows in before it gets drawn jnto the feuit room (I don't really know what's it doing if anything more than peace of mind)
