expensive bit of kit... but nicely done!

[@brucemoores366]

Thanks heaps for all the vids. A lot of extra work for you that is appreciated thank you

[@OakandSpore]

Very welcome

[@2420orion]

If you bring your intake around the other side of the chamber it will push out the co2 quicker and give you a more accurate reading 😁 Awesome fruiting room boss!

[@dronkarian]

There are some CO2 transmitters with control output built in. That could reduce the system components a bit maybe. And there are ones with a pipe fitting, to be connected to a ventilation pipe directly.

[@Joe-mf9zz]

AWESOME BUDDY I LIKE YOUR SETUP, SUBSCRIBED!

[@OakandSpore]

Thanks!

I needed to see this video helped me so much because of that I gave u a thumbs up 👍 and I subscribed

[@OakandSpore]

Thanks mate! I am glad you found it helpful :)

[@joaquinezequiel889]

Hello! Nice video. Thank you for sharing. I want to ask you why did you put the exhaust vent near the floor instead of putting it near the ceilings

[@maodo-ma-Ngai]

Thank you.

[@prelwitz13]

Id love to show you my two barrel PID controller I made. I wonder if you were to flip that water proof fan around if that would help your readings. CO2 is heavier so it sits at the bottom of the grow room. With that fan flipped around it would be sucking in air from the bottom of the grow room where most of the CO2 would be.

[@OakandSpore]

I have flipped it, so it pulls from the bottom now. But I doubt the co2 has time to settle anyway, there will be too much air current moving around.

[@JOATJESSE]

Did you program a pi or other unit? Thinking of building my own system to ensure things like hysterysis is taken into account in the logic for the sensor readings because if the amount of airflow change oxygen exchange and CO2.

[@brianmcquain3384]

Nice job!

[@OakandSpore]

Thank you! Cheers!

[@thanksgivingshopper5851]

Why don't you keep the sensor straight into the room but have to go through a small fan?

[@K33p1TS1mpL]

I tried growing lions mane from one of the kits from North Spores in a mono tub and it turned brown… starting from scratch again looking following your video with my own grab spawn and substrate

[@joshlindsay4629]

hey mate, love your videos. currently building my own grow space for oyster mushrooms, im setting it up inside one of my spare rooms in a 2x2 grow tent, being inside i want to maintain a negative pressure inside my tent the whole time, whilst engaging my main exhaust fan with a c02 monitor, do you have any reccomendations for a very small cfm fan that will create just enough negative pressure in my grow space? thanks!!

[@andrewbarnett2761]

I'm loosing humidity cause of fae. Anytypes. Maintaining around 76 humidity and 770 co2

[@liverpoolhikers]

any help on programming the OMRON E5CC would be great

[@OakandSpore]

Have you got the manual for it?

[@liverpoolhikers]

@@OakandSpore yes how you change from Temperature Thermocouple to a co2 probe ????

[@PitchforkAcademy]

Hey bro sorry if you covered this already but can you tell me which ip68 fans you use?? Cheers!

[@PitchforkAcademy]

Help me out please bro I'm trying to set up a small fruiting tent and I can't for the life of me find ip67 or ip68 fans. 😑

[@OakandSpore]

If you google ip68 fans you will find some

[@PitchforkAcademy]

@@OakandSpore Uhh yeah thanks bro because I haven't tried googling it... 🤦‍♂️

[@OakandSpore]

I'm not sure why they are hard to find, I get a lot of options when I google them.

[@PitchforkAcademy]

@@OakandSpore Well for one thing, you won't just tell me which one you use and where you found it... I've found a few, but ideally I'd like to find one in NZ.

[@kalunmyers4294]

Big fan. I run a small gourmet mushroom farm in Louisiana USA. 2 requests. 1. I didn't see your safety crocks on when you entered the fruiting room. We gotta fix that. 2. Will you read this sentence out loud in your next video PLEASE. "Stop blowing air into my ear." it will tickle your American subscribers I promise.

[@OakandSpore]

Haha I will definatly read something along those lines. Wait till you hear me talk about my DIY deck.

[@lindalbonomo]

ROFL. You truly are a funguy

[@gladyssun66]

thanks for sharing, we are curious where is the CO2 sensor? inside the grow room? But we didn't find from your video, can you help? Thank you

[@OakandSpore]

Oh, its mounted in a pipe which a fan blows air from the fruiting room through. There is a video showing it.

[@gladyssun66]

@@OakandSpore thank you so much for replying me, can you send me the link? appreciate

[@gladyssun66]

no bothering, I found it, you said "CO2 probe" it should be the sensor :)

[@trevorhoareau7203]

Hi great vid Does that mean you don’t need to leave fan on and keep room at operating humidity for longer before fan replenishes the air

[@OakandSpore]

yes, if you control co2 you only need to FAE on demand.

[@inducto]

What do you do with the expected mold on the walls, as result of the humidity?

[@OakandSpore]

Water blast and disinfect

[@APokeInTheEye]

Something I didn't get for a long time... How does one even raise co2 levels. So you use shiitake blocks? Are these like, for a lack of a better word, leftovers? What are these blocks? Specially for co2 levels? 👊

[@OakandSpore]

The mushrooms raise the co2 as they breakdown wood.

[@dustineskra792]

I realize this is an old video but I just got my CO2 monitoring set up but my oysters still seem leggy, the rest of the mushrooms are ok. The fan turns on at 700 and shuts off at 650. CO2 doesn't get above 800. Any ideas would help.

[@michaelduggahlas2798]

Nice setup. Is that co2 probe rated for high humidity?

[@OakandSpore]

I'm not sure. I looked at other probes which were rated for extreme conditions but they cost $1000's. This was cheap from ebay.

[@jozefjanech1705]

have you a link ?

[@cjmac3636]

nice vid! how were u able to connect the fan ro the transmittor so it turns on when transmittor senses high co2? also is it possible to hook up 2 fans?

[@OakandSpore]

The controller connects to an Omron PID, which is programmed to turn the fan on when the CO2 gets too high. Yes you can connect to fans to it as well.

[@skullkap22]

I appreciate your videos. I love your setup. I wish you the absolute best with your endeavors. I am currently replicating your set up. I know nothing about electricity. What solid state relay with heat sink do you have with your omron?

[@OakandSpore]

You need to get a SSR that suits you power supply. Ours is 240v, so I got one to suit. If there's. Not one listed in the comments I will add one today.

Whatever resolution you're uploading with does not scale well on my phone

[@nicklegaux9173]

Nice! How were you able to get the CO2 probe to work with the temperature controller?

[@OakandSpore]

So most PID's (process controllers) can function with other measurements, as long as it can take a different input. Most common are a 0-10v, or a 0-5ma (I could be slightly wrong) so instead of attaching a thermocouple, you can attach any probe that's output is 0-10v. My co2 meter is 0-10v, and its measurement range is 0-2000ppm. So 0v = 0ppm, and 10v = 2000ppm. The temperature controller is just a device to interperet the input and display it as a number on the screen (and control it)

[@nicklegaux9173]

[@YADA70073]

Could you recommend for me which CO2 Sensor Module is better for making project of Mushroom ? Because i want to get data of CO2 Sensor to live realtime for mobile

[@OakandSpore]

Unfortunatly I cannot reccomend a CO2 sensor to give updates to mobile as I have never done this myself, sorry!

[@ripoffrecords]

Why did you choose to build your own over an Inkbird CO2 controller? I've looked into setting up like yours but the components are gunna cost me as much as an Inkbird plus my time. Just wondering why you went that way rather than purchasing a "plug n play" type deal. Because you hate Inkbird? xD

[@OakandSpore]

I have never seen an inkbird co2 controller. Inkbird pid's are ok, but usually their probes are garbage. Good probes are the key.

[@eugenemwangi6711]

Hello. Very informative. I have a question. During the day, when the exhaust fan sucks out the air from the grow room, how is fresh air then forced into the grow room?

[@OakandSpore]

There is an open vent where air can come inside. IO do not force fresh air in, rather fresh air gets sucked in.

[@jakegardiner6185]

@@OakandSpore negative pressure is a good friend!

[@YoungTeeke]

Hey if I sent you a video of my setup - all the tools I’m using - all the fans diggers etc - would you be willing to consult me on what you would do / how / when. I have successfully fruited a few blocks of lions / pink oysters but before I do this on a large scale I’d like to have someone of your skill look mine over and give me sort of like a feedback report. Definitely willing to pay

[@OakandSpore]

Can do, go to my NZ website and send me an email through the contact form there.

[@PitchforkAcademy]

Bro you do realise that co2 is heavier than air, right? Your censor pipe is drawing from high in the room, so it won't read high until the room is almost full of co2. You should run the fan in the other direction and pull your reading from near the bottom of the room... 😉

[@OakandSpore]

I don't think co2 is heavy enough to be noticeable on such a small scale, and with air mixing inside the room. Otherwise if you dug a hole outside it would fill with pure co2, which it doesn't.

[@PitchforkAcademy]

Actually it is, and the smaller the scale the more separation you get. Unless your fans are on the floor pointing upward (and very strongly), most of the co2 will be on the floor. Try reversing the airflow past your censor and seeing how much more your co2 extraction is being activated.

[@OakandSpore]

@@PitchforkAcademy the atmosphere in the room is replaced once every 6-12 minutes, so no I don't think the co2 will be a higher ppm level at the floor, considering the extractor sucks the air from floor level. I will test it next time I am at the farm.

[@simplyiresistabl]

just seems to be overkill on the tek...exhaust cycle from the bottom freshaair filtered from the top..... cycled would have same effect.... just maintain humidity and temp.... kiss

[@OakandSpore]

It is adding complexity, but I enjoy it doing it.

Nah man, not exactly what I've been searching for. I just need to autpmate a few boxes or one closet.
