Isopropyl fumes are killing me I moved to a small lab 7’x9’ and it’s just recirculating air with a 3’x 4’ flowhood from myers mushrooms, I spray a lot of 70% iso and these last few weeks my throat and lungs are sore and irritated, I’m thinking to try to positive pressurize the lab by putting a hole in the wall and backing the prefilter from the flowhood thru it(maybe a grow tent on the prefilter side to create a “pre conditioning room” and run an air purifier in there too)and cutting a small doggy door hole low in the opposite corner in the lab to let air out, do you think that will get the iso fumes out of there? Until I do that I’m getting a respirator with organic vapor cartridges cuz it’s really hurting, any advice would be much appreciated 🙏

tyvek suits

Hey do y’all reuse and wash your tyvek suits for lab work? If so any special sanitizer or bleach? They say single use but I’m thinking I can wash them? 

P Rex looking to be a Kick Ass mushroom.   Luckily NH Eric helped me out by fruiting them so I could go vacation for a week and not fuck them up. Been getting pictures but they apparently look to be almost 1 pound a mushroom. Holy shit right!?  This is Milligan's hand/picture. 

I'll be up at the Maine Fungi Fest at the NH Mushroom table, I hope to see some MycoWizards there  

🤘☮️🤘

Afternoon Y'all! Just posted up a video of a conversation between MycoWizard Will MacHugh and Myself discussing the importation loop holes Chinese substrate producers are using and how we can change that with a simple survey...take just a couple of minutes and fill out the survey out here:

Photo is to catch your eye! Did you know if you pasteurize dry substrate (combo pellets or otherwise) you can then add UV treated water to the bag in the lab, spawn and set to incubate!? Can you guess which block is hydrated with UV and which is hydrated before the cook?

Tuesday Frigging Night 🤘☮️🤘. Got some agar, got some Liquid mediums and I'm cooking French fries at 420°.  This is a good day and I can't wait to take pictures of the cool shit this is all for. Hope everyone is doing well, fully stocked with Green bud and happy for this summer.  I am. 

Been a while and I probably need to catch up on the threads.  I was wondering if y’all had any background info on the JC shiitake we got recently? Media it likes, moisture content, where it came from or strong suits…?? We’ve been calling it the Jesus strain and nobody fucks with the Jesus! 

Also any chance we could get y’all’s Maitake and Black king oyster in the culture club soon?!  I’ve tried a number of maitake strains and I think all Of mine suck. I even stole one from earthfare haha. I’ve tried them in bag fruiting like your over production drying video both in A and horizontal filters with nothing like what y’all got!  Great video!!!!!

My BKs are cut and BS as well. Y’all cultures knock the shit I have out of the park! 

Can anyone provide info or links on boiler water treatment filters/systems.  I couldn’t find the right thing. I’ve been really burning out a bunch of elements lately. 

Also, y’all know about a company that does mushroom extraction services like powders, dual or tinctures?? 

Calciums role as a supplement in higher fungi...all these are worth reading.

Who's using the black bags?  Do you like them? Wondering if the magically increased yields are happening with Chesnuts also. They are pricey for sure.  Found 100 for $60 but just wondering other's thoughts/experiences

Hey ya'll! I have a grow room question I've been puzzling over- how do you prevent a humidifier system that pulls air from outside the grow room from creating positive pressure when the exhaust fan is off?

I run a ultrasonic mist maker in a water barrel for humidity, and currently have my intake fan ducted through it to blow the fog into the air (I run an intake fan as well as an exhaust but have the intake at a lower setting to keep negative pressure). I used to run my fans continuously, so the mist maker would just turn on and off via my humidistat and all was well, but I recently picked up a co2 sensor, and now since my fans aren't running continuously, I can only humidify when they're on. 

So now I think it makes sense to separate the humidifier from the ventilation system, but if I add another intake to pull air from outside into the humidifier barrel and into the grow room, the room would go positive in the case that the humidifier is running when the ventilation fans aren't. 

How do you deal with this? Any humidity system will push some amount of air into the room, and if the ventilation isn't always running wouldn't this reverse the pressure? I suppose I could add another lower powered exhaust fan to balance it out, but I'm just wondering if there's a simpler way. Or maybe the airflow from the humidifier isn't enough to cause an issue, either way I'd love some clarity!
