I have been using a manual CO2 meter to read grow rooms and then on/off timers to adjust cycle times on negative pressure exhaust  for a couple of years. I have multiple grow rooms of 165 sqft.  I'm contemplating moving to CO2 controllers, primarily for greenhouses, and I see a few out there for under $150. Any preferences? Good experiences, bad experiences? 

I have one InkBird that I use primarily to exhaust the whole facility during closed up winter months.  

I just watched the combo pellet episode and i'm sold on them! it does seem like they would make our life easier for sure. Only question is, do you guys know about any distributors up here in Quebec? I mean they look so helpful i'm considering trying to develop some up here if there's no suppliers around.

Just watched the Culture Preservation episode, short but sweet. In the daily grin I don’t see myself in the near future using a deep freeze cryogenic method, I shall leave that to you guys. But the slant method at 34f is possible or the sterile h2o method at 34f would be so helpful to just grab and restart a line. That is what I think most of us on small farms want to see more of. The ability of every so many months to get a culture from you and expand and store for a limited time of production would allow being proactive to future production problems instead of being reactive to nightmarish results of when a culture shits the bed. I would also like to thank you guys for the great service I have received for the last few years keep up the great work. Also would like to see an episode on the KOM shiitake and other peoples techniques with this one as it has been the fastest shiitake I have grown so far a few less fruits but 2 weeks less in the production cycle.

Re: Pheno Flick 3: Lion's Mane - Been working to to dial in my Lion's Mane and this video was super helpful. One thing that really caught my attention is your standard spawn to substrate ratio, with the range being from 2% - 5% and the "standard" at  ~3.3%. I have been experimenting within a 5% - 20% range, so I am excited to try out your standard and go from there. Up until recently, I have been using Liquid cultures and agar slurry for culture expansion / storage, but have transitioned to Agar and grain master method, which makes soooo much sense. Thanks!

I'm planing to build a new laboratory with 2 Fan Filter units 4x4 feet's. I wann have positive pressure system inside like you guys have in one of podcast. Here I'm sending my poor picture how is should look a like. First room is Lab, second is mixing/cooking area for grain spawn and third is like halfway. On picture you can see what are dimensions of all 3 spaces. I don't have a lot od space to build a plenum so I was thinking to just add some fan with filters that will blow air inside of lab but not too strong so I don't get turbulent air in front of my floowhoods. How can I calculate how strong fan I need for that?

Chestnuts 🤘.  Couldn't get coroplast but this is better than I expected ATM. Lot of work and about 100% know-how from RR and the Mycowizards. Thanks ☮️

Hello mush community! I just saw the episode Steam Generation and I was wondering can someone put the link of that Chinese steam generator that Erik was showing because everything that I found is not as cheap as he mentioned in this episode?

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?? 

Hello ya'll! There has been a lot of talk as of late in different forums and groups about the efficacy and practical use of old study protocols specific to chemical dedikaryotization, so i thought i would share this interesting and easy protocol for isolating two monokaryons from a single dikaryon. I'm not sure how many folks are getting as into the weeds as we are about mating and DNA analysis but this is a pretty cool primer for what is possible. Some practical reasons for needing to preform dedikaryotization is if you are trying to generate a new phenotype from a dikaryon that cannot produce mating pairs within its own spore production (i.e. Shimofuri Hiratake or PE or Enigma, among many others in the gourmet, active and medicinal world). The process of dedikaryotization allows you to pull the mon parents of literally ANY Di and from there perform crosses to continue breeding. Anyways, I hope this is interesting and insightful for ya'll and hopefully in the next couple months we will put together a full deep dive on the matter! 

I hope everyone has a good weekend coming up. I was able to make it through rt 16 to dover after work today without getting killed by the Massachusetts holiday migration. I've already won. Those birds are Reckless but an amazing sight to see.
