Hey peeps! In this post I will be expounding upon the general philosophy of a mushroom fruiting chamber (FC), the concept and function of today's common approaches, and presenting one of many examples of FC theory application towards constructing a most effective mushroom fruiting environment.
FC Philosophy
There are two main aspects to a mushroom fruiting chamber - fresh air exchange and humidity. Though the high humidity is necessary to keep substrates hydrated, air exchange is more important for initiating mushroom fruiting and supporting hi yield.
Reaching and maintaining appropriate high humidity is easy. Facilitating or forcing the exchange of air is almost just as easy. Developing a perfect balance of the two is a different matter. The goal with our chamber design is to retain 90-100% RH while avoiding too-great of CO2 buildup.
As you retain humidity, you (1) Reduce moisture loss from mushroom substrates, usually a plus (2) Retain CO2 that the fungi 'breathe out' - Low CO2 levels are called for. (3) Retain heat that the fungi produce. This may become a problem for cool-weather species, or by putting a cap on humidity and both allowing & expediting evaporation from substrates
As you increase your airflow, you (1) flush out CO2 buildup, increasing mycelium metabolism and stimulating it to fruit (2) decrease your humidity (3) reduce the ease of increasing humidity (4) increase the amount of water involved, both for the FC and substrates (5) Flush out excess heat
________________________________________________________________________________
Some species are more tolerant of hi-CO2 than others. Examples from most to least CO2-tolerant are Cubensis, Shiitake, Galindoi, Panaeolus, Oysters For that reason, Cubensis can grow prolifically and properly in an environment that would stifle proper fruiting for Oysters. If you understand the potential approaches to FC dynamics you are capable of designing an approach however you like.
These are the main avenues of approaching those dynamics, related here to common mushroom chamber designs.
PASSIVE AIR EXCHANGE is allowed by designing a chamber in a fashion that humidity and heat cause convection in the tub enough to keep CO2 levels from building up too high. The "shotgun" fruiting chamber (SGFC) has holes in all sides with moist perlite in the bottom; Mushroom substrates above produce heat and humidity which gets air flowing up and out, bringing air in thru the perlite in the bottom which is humidified by the perlite's moisture, and in turn that humidified air continues the motion up and out. For this reason it is also a passive humification chamber. "Monotubs" in still-air rooms will develop heat that causes convection forcing warm and CO2-filled gas out, particularly out the top, and cool outside air drops in thru the poly-fil holes. Very light stuffing is needed here or not enough circulation will occur, which is very likely due to the hi production of CO2 from their large substrates. Many greenhouses are made using open flaps, or with slits cut in the sides, for some gradual air mixture.
ACTIVE AIR EXCHANGE is made by use of fans, either directly or in a "cool mist" humidifier, and done when passive air exchange methods would not disperse enough CO2. Fans quickly and effectively move the air thru the chamber, but result in an immediate plummet in humidity. "Cool mist" humidifiers use fans to move air, but paired with an "impeller" also make them an active humidification method, causing not plummet in humidity but gradual climb. "Monotubs" can be considered to have active air exchange when fans are employed to force degrees of convection amongst the polyfil holes. This is better for them, as they have huge air needs due to the ginormous block of mycelium in them.
PASSIVE HUMIDIFICATION occurs by evaporation from substrates, perlite, container walls, towels, anything that gets the job done. As stated above, SGFCs are humidified by incoming air filtering thru the dampened perlite in the bottom. Monotubs are humidified by evaporation from the sheer bulk of moisture-holding substrate in the tub. Greenhouses using passive air exchange can potentially use bulk substrates to build humidity as well, but reaching humidity may be difficult without stifling airflow.
ACTIVE HUMIDIFICATION is from electric humidifiers. It is usually paired with active air exchange, as passive humidification could not effectively humidify the air with active air movement. "Cool mist" humidifiers (i.e. modified Vicks 4500) use impellers and fans to move humidified air. It's quite possible to have high enough humidity just from this alone, and they're perfectly simple to rig to a chamber setup. Ultrasonic humidifiers use a high-frequency 'speaker' to intensely agitate huge amounts of tiny water droplets into the air. They are tricky to use since they are quite literally force-wetting the air, so below I specifically delve into using these devices.
________________________________________________________________________________
There are plenty of good instructions available for shotgun terrariums and monotubs. I would like to focus upon "greenhouse"-style fruiting chamber methods!
Further, of what very few "cool mist" humidifiers work for this purpose, all of those are easy to use for just about any chamber. I'll elaborate on it below...
… thus I will focus on ULTRASONIC HUMIDIFIERS (USH) for now!
 
There are countless forms. They are common, readily available, inexpensive. They blast huge amounts of mist into the air.
However, they are not adequate for mushroom fruiting chamber use by themselves.
In household use, these tiny droplets of moisture evaporate quickly in the air, or shortly after landing on any surface. In a mushroom fruiting chamber however, where the humidity is already very high, it's quite likely that much of this moisture simply fall to the floor and collect again as liquid water.
For this reason, the mist from USH must be "stirred into the air"
 A good-old-fashioned fan. Nothing stirs air like. Must be a pretty small fan - you don't want rampant vortexes of air in your chamber! An USH paired with a fan is little different that the popular Vicks v4500 coolmist, that device is essentially a fan system cleverly paired with an ultrasonic impeller anyway.
A fan makes the difference between 80% with water on the floor and 98% humidity with a 'dry' floor.
This will only work best for you after experimenting with many arrangements to find the way best suited to the space and barriers in your chamber. The airflow inside the chamber from the fan must evenly mix the USH's mist into the air. If this is done correctly, it should only take a couple minutes of the USH and fan running simultaneously to fully humidify the chamber, even right after a complete air flush!
The fan must only be running when the USH is! Simply run them on the same timer or humidistat. My recommendation is to use a small-increment cycle timer (you can make yourself cheap & easy!) and an analog hygrometer to determine how many minutes per cycle are necessary to retain humidity.
________________________________________________________________________________
Although the design to be outlined in this post is made to not require special air exchanging, many designs are not, so I thought to add the best approach to greenhouse-style FAE to complete the info helpful for building any approach to a large GH.
FRESH AIR EXCHANGE is always the primary concern with fruiting chambers. This doesn't necessarily mean that you have to have a specific vector of air passage in your design. In the case of tote FCs you could fan them out many times a day.
With such a large chamber as I built shown below, I need only open the door for a while a couple times a day. With loads of "bulk" substrates you may need to do this and/or fan it out a bit more often, if not install an active air exchange method… But even with lots of straight-grain containers I only open it up once a day to flush the air.
In my case, the nearby open window keeps some air mixing around the edges as well. Experiment with your environment!, but make sure it's stable before you let it govern your FC! It can take repetitive visits off your time and work.
If you find that you need more airflow, a "cool mist" humidifier is perfect to supply gradual flow without stunting your humidity. In fact it will likely reduce your USH runtimes further. Unfortunately most "cool mists" use wicking filters. These are NOT suited for mycology.
To my knowledge, pretty much the only humidifier for the job is the Vicks v4500, but it absolutely rules for the job once you've made the modification, which is necessary if you put it inside your chamber because it will otherwise shut-off in hi humidity.
 In fact, it rules so hard, that depending on how you choose to rig it up you will either turn your USH down to occasional short bursts or even stop using the USH altogether.
Here's how to modify that humidifier, instructions by OZZ:
Quote:
I disassembled the unit and cut the power wires going into and out of the humidistat control, completely disabling it and bypassing it altogether. I took awhile to figure out how to disassemble it without breaking it, but once I put it back together it worked perfectly! My humidity gauge is PEGGED inside of 4 minutes. It has 3 speeds and I was able to turn it all the way down to the lowest setting and still keep the humidity gauge pegged at 99%.
All you do is pop off the bottom cover and remove the neck. The trick is that the impeller WILL pop off of the axle, exposing screws that you can take off. It doesnt feel like it, but you just need to wedge your fingers underneath it on both sides and pull it off. Then disassemble it, remove all the covers exposing the controls and wires.
Dont worry about all the connections, its pretty daunting at first. There are only TWO wires going into the humidistat controller: a BLACK and a WHITE wire. Snip them both, strip a portion of each, and tie them together. The whole unit is wired that way so there is no worry.
The easiest use of this humidifier is to simply set in the bottom of the chamber. It will constantly cycle the air in the chamber and keep it at near-saturation humidity as well as these ultrasonic humidifiers and fans can, since it's pretty much that same thing. However, that does not provide air exchange.
It can be as simple as having slits in the plastic walls of your chamber so that air will mix somewhat but not enough to outmatch your humidifier's capability of keeping the humidity up.
The ideal use of them is to have them outside the chamber with the output blowing in, so that they flush air through the chamber. This is more difficult to work up as it requires running some form of tube or tent over the output. It is the most rewarding though as it results in full automation with the shortest USH bursts or none at all.
________________________________________________________________________________
Now to show you mine! Truth told, this is not intended to exemplify a professional or long-term fruiting chamber. Was thinking of ways to make FC space and I wanted to show this could be done. I put-together this GH as a result of countless FC experiments with most every approach and angle I had seen or imagined. I've made several angles on "greenhouse"(GH)-style chambers, mostly variations of the mini-greenhouse or wrapped shelves. All of them worked wonderfully as long as a way to fully-cycle the air was possible. That is their one main hurdle: the air is much more difficult to properly mix inside a fully loaded GH . If the chamber is designed to keep open passage of air amongst the entire chamber, this is a cinch! I do this by building my "greenhouse" around two shelf units with space between them. That space makes it easy to move the misty air amongst the whole chamber, no matter how large!
The goal was to quickly and easily (less than 2hrs) assemble lots of efficiently-used fruiting space (106qt tubs hold 18 of my fruiting containers, each shelf 38; 8 tubs 144, 8 shelves 300) with any brand's variety of cheap & simple common materials (USHs & fans) that was super-easy to access ('walk-in') required no automated air exchange (lots of present air, big door) no misting (USHs keep air almost saturated wet) and won't get stale air (cycling fans).
 Here are two such shelves set on a plastic drop sheet.
 Plastic sheeting is also wrapped around the back and top of the chambers. Many things work to secure the plastic around the shelves; I choose tape.
 Two overlapping plastic sheets are used for the front. This creates a "door" that loosely encloses the chamber when it settles.
    For this large chamber I use two USHs - one on the bottom with a small fan above it blowing into the bottom area, and another one in the middle with a fan behind it blowing into the upper area. This creates swirls in the space between the shelves that stirs the air amongst the shelves as well.
Don't start off with two USHs just because you see me using two for this large chamber. Start out with one! One USH is usually more than enough, in fact has to be cut-back from running constantly somehow, those modified short-cycle timers I mentioned before are perfect.
I am only using 2 to cut their running time in half. This has NO effect other than having to refill half as often but twice as much, besides possibly distributing humidification more evenly at first.
If you use 2 USHs before you're quite familiar with these tricks to using them, you'll end up with water all-over your chamber floor.
When you get them running on a stable cycle, try placing your calibrated analog hygrometer in different places within the chamber to test for evenness of humidity. It will be likely that different spots have different humidity, but as long as it's above 90% RH you'll do great!
 Hygrometer reads no less than 95%RH in any spot once it's been chilling closed for a while, 98% in most places, 100% in the areas the fans first blow the USH mist when running.
Gotta tag a few action photos!
    
This post has been edited, but despite the cause of its mention I chose to leave this section here for kicks: I contest that fuzzy stems are due to hi CO2 or "stale air", rather that it's allowed by constant hi humidity which does always occur in situations with too little air exchange. If humidity were to fall for any period at length those sensitive spikes on the base would and do wither back. A situation that builds-up CO2 or stale air would indeed fully allow fuzzy stems… but we know that it's a function of many species for locating new food debris around fruits. I have some "strains" of Cubensis that don't fuzz up at all, even in those environments, so there is definitely a factor of genetic disposition to the behavior.
These FCs have lots of air so CO2 buildup to excess is slow, usually flushed before a high level reached, and the air is kept nicely moving so avoids becoming stale or hot. Your FC is not necessarily receiving inadequate fresh-air just because Cubie grows more mycelium. Play around with it!

I like that back to back shelving with the humidifier in the middle. I've been piecing together ideas for my FC redesign. Seems that provides a large area and a good amount of air to keep things stable.
I admit I haven't read the entire post all the way through yet, I'm posting in part to keep it tab'd  But what are you using for lighting? Just that window? The mushy's look a bit long and stretchy is why I ask.

They're so tall because I used to take clones of giant mushrooms all the time, and these are those still. They're pretty sweet yielders, the length is why, def not a problem. Not all of them do that
  These two are a single isolate, it happens. Behaviour varies with many factors
I've kinda always had a thing for the tall ones.
 
Light is currently some floros. Will be switching to certain blue panels when they come out.

You're right about the large area. Does take some paced running of the ultrasonics to keep it up to near-saturation but the large air content as well as the airflow allowed is a huge advantage. Makes using USHs both possible/easy and worthwhile.

There's really is no reason to ever use a fan in a GH, monotub, or any other FC.

Depends on your selection of "necessary." Humidifying air and automating air exchange are pretty good reasons, no? For many peeps they are, at least. Many of us don't want to mist lots so that big blocks of subs can supply that humidity. How are you humidifying your greenhouse if not with a fan? Especially with strong FAE. Coolmist humidifiers operate almost entirely by fan. Even most ultrasonic units have a small one to get the mist piping into the air.
An indoors greenhouse of oysters grows a bunch of scraggly long pathetics without full air exchange 3-6 times an hour.
Fans are not used "in" monotubs, but monos work better with fans circulating local air.

That's different though. The humidifier is blowing out humid air and the fan is integrated so you don't have much of a choice.
But when you do have a choice between relying soley on air holes and a fan, holes can provide just as much air as a fan and can distribute that air more evenly. The fan will generally cause more moisture loss from the substrates, some more than others, which means more misting is required.

Until I built this greenhouse, for a long time I'd been using a mini-GH with computer fans installed on it to blow air thru. A short-cycle timer ran the fan 50 seconds every 40 minutes, and another short-cycle timer kicked in the ultrasonic right after for a few minutes.
At first I experienced like you said, having to mist a bit, even tho the ultrasonics quickly rehumidified the air. The problem was the vortex effect with dry air. Whether coolmist humidifiers create such a blowing vortex or not doesn't matter since that air is humid, but fans blowing dry air around with substrates will indeed dry them out.
Adding an air filter between the fan blowing in and the chamber killed this vortex and the air steadily migrated out without swiping moisture off the substrates. Having cleaner air being blown in was a nice plus. The ultrasonic then humidified the air fully; no more misting than a fine-tuned monotub. Kept this setup for about a year until stealing its humidifier for making this one.
Using a fan only in synchronous with an USH has the same effect as a coolmist humidifier. As said in the post, that's pretty much what a Vicks v4500 is. Any vortexing air from the fans does not cause drying problems when it's carrying countless water droplets. This has been my consistent experience, and this use of USHs is based on that.
All that said, you can see the GH I outlined making here doesn't have any automated fresh-air exchange. The fans only mix the ultrasonic's mist into the air, so it doesn't swipe moisture off the substrates or bring drier air into the chamber. Fresh air exchange is provided a couple times a day with a lingering open door

i like the construction of your door very nice idea, and using 2 shelving units like that to build a 2 in 1 gh is a great idea, since then you have room to be INSIDE the tent, i love it.

I think fans are almost mandatory in a GH style FC, or any other LARGE FC. It helps to keep the air uniform and promote some FAE through the air movement.
Have you ever done a run in a GH style FC kizzle?

I like the setup, looks productive and easily breaks down into other usable material if you need shelving or make a bigger one.. good idea 
thats what like $80 in shelving and like $10 in plastic? Nicely done.

$3 in plastic.
The shelves were a bit more than $80 together, but these in particular were worth it to me in particular. I won't say the price, as less-expensive options would work just as well for most. Wire metal shelves are more expensive new and are prone to rust, but actually work better if you can find them free used or something.

Aren't you a little nervous about having those non waterproof fans inside the GH that's at 90%+ RH? They're going to rust and/or short out eventually. I hope they're at least on a GFI.

If your USH or coolmist are inside your GH, then you have fans in your GH already No, not nervous Everything degrades. It's why we gotta keep stuff alive, maintain, replace.

So i know that the cool mists with wicking filters are bad because they encourage bacteria growth. Is this still an issue if I have one that takes non humid air from directly and only outside my GH and pumps it in? Will i still have a big bacteria problem?

If you change those filters all the time the grodiness won't be too big a deal. You may not achieve strong humidity with them.
I once used the chassis of a filter-type coolmist, without the filter and water, just for a fan on an ultrasonic. That would be the only potential rigged-up use of wicking/filtered cool mists for FCs, in my opinion
