    During these crazy times I've been picking up new hobbies right and left... mushroom cultivation being one and home automation / IOT being another... and of course, I had to combine them as well. I've thrown some sensors into my grow tent I'm using as a fruiting chamber.

    What kind of range for CO2 level is "good" for a fruiting chamber?

    Right now I'm turning on some fans when it passes 1000ppm... which cause a huge drop in humidity until the fans turn off.

    Damn that’s way nice ! I run my fan 1 min every 5 in a mini green house never can keep my humidity over 60 % without it raining since it isn’t in a climate controlled area but oysters lov it

    What type of sensors u running polo? That kind of info would be great .stamets books on growing have all those types of info on c02 and air exchange and humidity.Thats a good place to start.If u can’t find it I’ll dig out my book.

    well duh I have Stamets book sitting right here on my shelf... thanks for the reminder!! hahahaha it's all right there in black and white! For future readers:
    • 95-100% RH for primordia initiation, gradual reduction to 90-95% after primordia form
    • C02 below 1000ppm and ideally below 500ppm
    In terms of my setup, I'm using DHT11 and DH22 temp+humidity sensors as well as a CCS811 sensor for CO2 and VOCs. Each sensor is plugged into an ESP2866 (wemos D1 mini style) which connects it to my local network. I then use ESPhome + Home Assistant to generate the charts from my screenshot as well as perform the automated actions (turning on/off fans and humidifier)

    You guys are crazy! Here i am with my shitty ass SAB... dude I am a devils advocate so id say get what fits! No room here not even for my SAB, wifey hates it lol! Go big or go home lol as long as you have a consistent airflow from it id assume you should be good... people get away with nothing at all and it still blows my mind, but I have cats and they are Trichoderma trains spreading contams through my whole house!

    @sleep just because I have sensors doesn't mean I know what I'm doing :p it's fun either way though! My wife definitely thinks I'm spending too much money on my new hobbies haha

    Ummm I'm probably ~$300 into it all things considered. Once I get it dialed in I plan on doing a write up which will have links to all the components.

    That would be awesome ! The price is pretty responsible for that type of control.If I paid myself min wage I’d be over that in time and materials doing it by trail and error.lol can’t wait for the write up .thanks polo

    Thanks for the idea, and for the nice graphs. I will make some like this, since I got some trouble with my measurements in th monotubes.!!! Thanks

    hey anyone ever try getting some small pieces of rock wool or something along that line sterilize them. put the pieces in the corners or any open places around the substrate. when about to start fruiting. flash steam sterilize some grass seed and place several grass seed into each piece of rock wool and sprout the grass as the mushrooms go to fruit??

    would that not help offset the co2 build up?

    Just a question about the CCS811 sensor. Does it tolerate the high humidity of the fruiting chamber without failing. It sounds like I have a setup similar to yours with microcontroller driven heat, and humidity sensors. And fan automation. Would like to add the co2 measurement but want to make sure the sensor can actually stand up to the environmental conditions in the FC.
