Damn, how many registered TC´s are there? When I read the the old threads all I see is new TC´s I´ve never heard of before, and I though I had a pretty good overview. Is there a list somewhere? I would estimate that there is about 30-40 TC´s?

I love going back and reading the old stuff.  When I first started cultivating back in 09, I used to read and follow a lot of agar's work.

I´ve been reading a lot about the "heavier CO2" theory when describing the functions of the monotub design, about the heavier CO2 laden air exiting trough the bottom holes. But from my research around engineering sites especially about indoor air dynamics and draft dynamics, it states that if the air inside a box is warmer than the air outside, then the colder more dense air will push in and warmer lighter air will exist trough the top.

This is at least the theory for a house with doors and windows, but I don´t see why it would´t apply to a mono tub with "doors" and "windows". Perhaps air is actually coming in trough the bottom holes and in that case we don´t need to worry about CO2 laden air collecting on top of the substrate. I have heard people have concerns about this if the bottom holes are not level with the substrate, that the CO2 will somehow be trapped on top of the sub, but to me this seems ridiculous. What is heavier and more dense? CO2 laden air or cold air? Well, both cold and warm air can be CO2 laden but in the case of a substrate the CO2 laden air will always be warmer than the outside air pushing into the tub so this should never be a problem.

I´m no engineer, feel free to comment on my reasoning :cheers:

It is not about how heavy the co2 is it is about how you stuff the holes...so say you have the tops loose n bottoms tight with a fan running in the room...air is gonna come in through the top just because it has the least amount of resistance and here it is forced out of the bottom holes so yes a window theory may apply here but more of car type set up...we have all been in the backseat when the front window is open

I like your inquisitiveness.
I'm no engineer either but the whole co2 theory that's been parroted and passed down to death in mush cult is plain bulshit. Heat's welcome.
Even the theory behind the placement of the holes and how they move the air in the tub by adjusting the poly has no solidity whatsoever, people just like to go with what has been stablished by the majority to be true, cos that's the easy route.

Pretty sure most skilled cultivators here that swear by holes and polly never tried doing a single grow in an unmodified tub.

Co2 ain't gonna stay at the bottom of the tub, no matter if the tub has holes or not. An unmodded tub covers all the organism's needs by just cracking the lid a little or even with the lid upside down. We're not growing oysters here for fucks sake, they're cubes and don't need that much exposure to the air of the room to grow healthy.

I'm gonna give again the stupid example I wrote the other day. You leave a human in a tote big enough with the lid upside down and that person won't suffocate, but myc metabolizes the oxygen far slower than a human being. What makes people think an unmodded tub will suffocate the myc when it is a nearly anaerobic organism if we compare it with a human being?
C'mon, let's use some logic. Logic or not, you can grow canopies in a tub with so little 'FAE' that most would consider nearly suffocating the organism, where in fact it has plenty of 02 to grow healthy.

I uses a similar analogy the other day, I said that you could throw cats inside a monotub and they wouldn't suffocate, if a mammal can survive inside a mono tub with polyfil stuffed holes then there is no chance mycelium will suffocate.

bod and cron thanks for the info!

BUT!!! Since the top holes are more loosely filled than the bottom holes then the warm rising air from the top of the sub will more easily exit trough the loosely filled top holes rather than trough the tightly filled bottom ones right? And since the colder air is more dense (and outside air will be colder at the bottom hole level than the higher up top holes) it is reasonable to assume that the more dense air will easily push trough even the more tightly stuffed bottom holes, but since the top holes are higher up where the air is not as dense will continue to seep out warm air that is pushing upwards from the sub all the time. To me at least this seems much more plausible that the other way around... hmm,, have to somehow prepare an experiment to test this theory.. (assuming I´m not running a fan in the grow area but instead leave the natural air currents in the area do the job)

Holes and poly still have their place though. If you need to stack the tubs you'd be better off with holes and poly, set and forget style, no fanning and misting bs.

I decided to measure co2 this week in my unmodified tub with a flipped lid. Here I'm measuring from two sensors across that week. There's not a lot in this tub. No holes at the bottom, just some gaps at the top for passive air exchange.



If I hang out in the room too long or breathe in the container, it shows.

No guarantee those numbers are accurate because the cheap sensor is off alibaba (MH-Z19), also sometimes the sensors autocalibrate to the wrong levels. Some variation I'd also attribute to temp swings.

I found this oxygen and temperature sensor, it's water proof, works with gases and liquids.

There are also other oxygen meters, see here. Ignore other gases.
Air is about 20.9% oxygen, see here. Mycelium use O2.

Imagine the air as a mixed substrate.

Y'all ever leave a plate too long and have it start to curl up? The suuuuper thin MEA plate I sprayed some reishi LC on colonized most of the surface, ran out of moisture, started drying out, and has now started rolling up slowly from one side. Plate is sealed with electrical tape around the sides, so airflow should be minimal to none.

Wonder if the myc would revive if I dropped it on some water and food...

It should, I've seen people clone from dried fruits.

What do i do if the pressure lock on my presto is leaking steam? It still comes to pressure. I just figured it shouldn't be happening.

My brand new 23qt spits steam out the lock for several moments after I put the weight on but before it pops up to lock into place and then it stops

My old one did it too and I thought it was a problem, maybe I bring the heat up too fast but it hasn’t caused any issues

I don't understand these measurements. What's the CFM and resistance? I am finally buying my flow hood. Yay! Is this like the metric system way of saying all of this stuff. https://www.ebay.com/itm/Nationwide-Filter-Company-17-3-4-x-11-3-4-x-4-5-16-Depth-HEPA-Filter-99-99/331947759619?hash=item4d49a0d803:g:croAAOSwHoFXu0Op&rmvSB=true


Oh nevermind. I didn't realize how small it was. :frown:
