My Sterile Room

I thought I'd share the sterile room I built in my attic. It's made from 3/4" PVC, 6 mil plastic and duct tape.
As far as locations go, it's probably one of the worst. My attic is full of white rot mold from old roof leaks and there are skylights everywhere that act serve as as ventilation. But this was the only spot the spouse would concede.
There is a small initial still air room that houses the entrance to the main room. The door is a Zip Wall.

Very cool! I am not familiar, what is the advantage of having a sterile room vs. just building a flow hood?

If you have a working flowhood I don't think any of that is really going to improve anything. It's kind of ironic too that you're building a sort of low contam tent but then you're putting the most contaminant ridden thing in the house inside of it, your own body. The most effective barrier is one that is placed between you and the stuff you're working on.

Stamets book recommended a proper clean room having up to 4 entrances before entering the final room. So in my model, I created a still air entrance room that is about 4x4 that houses the zip wall. So it's basically one additional place to minimize introducing dirty attic air.
When entering the first entrance, there is 70% IPA and gloves to wipe myself down and everything around me down. When I unzip the main entrance, positive pressure from the hood running inside minimizes the introduction of additional contams upon entry.
I've also taken measures to clean and sterilize the pathway I take outside of the tent to get to it. Finally, I have some degree of climate control in this room and have the flexibility of tapping an outside air source and directing it only into this space when needed.
Is any of this necessary? I don't know but I could not, in good conscience, simply work in the open air of my attic.

It's cool as shit and if you got the time and money why not. But bro you don't need that for growing some shrooms. Still air box in the garage will get you more mushrooms than you can eat or give away. But like I said that's cool as shit and I wish I had the resources to even think about doing that.

No he's not, one guy on here likes to think he's like God because he posts 20 times a day on a message board and likes to shit on stamets when he hasn't accomplished 1/100th of what stamets has. When if they where in a room together this someone who claims to be so intelligent would get shit all over, just a shame I see so many new users listening to him - I can't blame them, he posts so much he just floods the boards and noobs think people with high post counts are cool.
Anyone with half a brain understands what was written 20 years ago should be taken with a grain of salt.
The personality ego cult is strong with that one, beware. He's working some shit job, not as a mycologist and isn't smarter than stamets.

Don't quote me 😁 But seriously this guy says mentions stamets recommending 4 entrances to a inoculation room? I'm unaware of the accuracy, context, or intended audience of this but it sounds a bit ridiculous tbh...

Some patients using weed when it was illegal could hate Snoop Dogg, cypress hill etc. For using weed as the way to getting money, in the end, they all contributed to the understanding of weed... So isn't it same with stamets... He is earning money yeah, so is everybod on this planet...

Were you having problems with you flow hood? If its working right unless you are working a commercial levels this is just one cool as fuk set up thats really over kill. I do love it though.

Nah, no problems with the flow hood but I imagine it will extend its life given the tent is preventing the amount of dirty ambient air that must be filtered.
This is all for fun. Overkill? Maybe - probably. I'm growing large volumes and having this space blends practicality with the fun I'm having from the process. The tent cost < $50 to build.
The tent also creates a different vibe to work in. Good vibes are a key ingredient in my product. 
I'm new here so didn't realize the baggage this forum has with Stamets. For better or worse, his book (Guide to Growing Medicinal Mushrooms) was the first one I found over ten years ago and I use it, as well as many other sources, as a reference from time-to-time.

Blindingleaf one of the best TCs uses a prechamber before his popup tent where he houses his flow hood.
So extremely similar concept to yours. If you get confused on who has the good technique remember blindingleaf has run a gourmet farm sterile work for years. Most people here just have less than a dozen tubs going so I'd say it's clear who I'd listen to - the dude making money supporting himself for years that way. May not have heard because he's a modest person.
Most people here don't have a room to dedicate to a lab so don't think a prechamber like that hurts, most of the guys without lab rooms just wish they could be like bl, and he uses a prechamber so, maybe there are concepts that someone can grasp from that Paul stamets said with a critical mind /grain of salt, not taking it as gospel carved in stone.
Pmd you ed. Good luck op. May consider another kind of plastic door, I know those zippers can be tight especially if you have volume of things moving in and out.

Im thinking of going commercial and would definitely do this. I have a plastic as entrance to mine but no room for this kind of thing yet.

That's a cool setup and packs a lot of functionality in a small space.

You aren't wrong on the door (or your other remarks for that matter). I only used one of two of the zippers in the ZipWall set, thinking I might want a door on the prechamber, but I decided not so now I have an extra.
I've been lucky enough that the opening can get as wide enough to bring in a knee chair, some shelving, and supplies.
The other potential downside of the single zipper door is I've noticed it can create the same effect that you get when you put gloves on a SAB. The billowing effect of the plastic may be sucking in more dirty prechamber air than the positive ambient pressure of what the hood is putting out.
We'll see how it goes. I'm sure this thing will evolve in the coming months.

Hey Brother, I like what you've done.
Just figured I'd mention that you won't have any positive air pressure unless your flowhood is pulling air from outside the clean room. If your FH intake is inside it'll just be blowing air around which will make a current, but not create positive pressure.
-------------------- Everything i say is completely hypothetical...
