Fully Automated Fruiting Chamber-Precision Humidistat (Pics) * 1
    #2042044 - 10/25/03 03:55 PM (13 years, 10 months ago)

Note: I don't grow any more, so don't ask me for shrooms.

Fully Automated Fruiting Chamber.  Click Pics For Close Ups.  This setup uses a precision humidistat instead of a timer to manage humidity.  Works better because the amount of humidity required is a function of the room temperature and humidity. A timer is a best guess.

A Full House.  This is a four-level greenhouse holding a variety of casings.


Give 'em light!  I usually open the curtains for a while every day, but sometimes I can't so this light is on a timer.  A few minutes a day is all the mushrooms need. More doesn't hurt though.


Add humidity.  This ultrasonic humidifier works well and is on a precision humidistat.  You can see the humidistat mounted to the greenhouse frame just above the center of the pic. It was calibrated with a very accurate sling psychrometer from Fungi Perfecti. It's set for 92% and I modified it so it's gives very tight control of humidity with a hysteresis of +-2%.  I have found that timers don't work well for managing humidity because the environment outside the fruiting chamber can change the humidity requirements inside.  I use  only distilled water to cut down on deposits forming on the transducer and other components of the humidifier.  A hose pipes the mist into the fruiting chamber.


Closeup of humidifier-hose attachment.


Another closeup of the hose


Another view of the hose routing.


Distribute the humidity evenly and add fresh air several times a day.  There are two fans; one is fully enclosed inside the environment and runs synchronously with the humidifier so the mist is quickly dissipated and distributed throughout the environment.  This keeps things from getting waterlogged by too much mist.  Notice the humidifier exhaust hose in the upper right corner.  The mist comes out of there and the fan immediately evaporates it into vapor so no little water droplets can soak anything.

The second fan is on a timer and is vented to the outside so it brings in fresh air and removes CO2 which can impede pinning.  The humidifier hose is visible in the upper-right of the picture.


Monitor the environment.  This is just a simple hygrometer/thermometer combo used to keep an eye on things.


Close up of results.


Closers still...


Another close up of some fatties.  The rightmost two alone were over 80 grams wet.
 

Here they are dried a few days after harvest.


First flush.


By popular demand, here's a pic of the incubator.  There's a jug of water on the left with a 200 watt aquarium heater set to 85F.  Notice also the small box fan which circulates the air in the incubator to keep the temperature consistent throughout the environment.  Without this fan, some jars get hotter than others due to temperature stratification in the air and the mycelium's metabolism.  The white wrapping around the incubator is a goose-down comforter for insulation.


Closeup of the incubator fan and heater assembly.  Note the white wire.  It's a remote thermistor so I can monitor the temperature without having to open the incubator.


Cool, eh?  :mushroom2:

Edit: Added some more pics.

My sweet sweet GOD! If any of my friends or pets ever achieve anything like this in anyway, they can retire. Beautiful.. simply beautiful.

That doesnt look too hard at all to creat. just shelving wrapped in plastic... in the spring(if I want to grow a quanity) I may try something like that.

NICE SETUP

I'd like to hear a little more about the precision humidistat. So it detects the humidity in the chamber and then the humidifier knows how much humidity to let out? Is that correct? You say they're expensive. How much did your friend pay for his?

That's right.  A humidistat is to humidity what a thermostat is to temperature.  I modified the humidistat to tighten the hysteresis to +-2%.  Normally, it's too wide (like 8%) to control the humidity within a sufficiently narrow range.  The device costs several hundred dollars, unfortunately.

Also, it's important to use a fan to distribute the atomized water from the ultrasonic or it will settle and waterlog everything.  The other fan is just on a timer and brings in fresh air periodically independent  of the humidity.

Where does the CO2 exit the chamber? Your friend has a fan blowing outside air in but there is no mention of a fan that blows air out. I'm very impressed my this growing chamber by the way.

What is the plastic surrounding the grow chamber? Did you just buy sheets of plastic and wrap it? I can't figure out how you did it, so I just thought I'd ask.

No question is so difficult to answer as that to which the answer is obvious.

There are some strategically placed one-way holes that let air out to compensate for the fan bringing fresh air in.

That's a commercially available greenhouse (PM me for a link if you're interested). It comes complete with shelves, plastic cover, and zipper. I made a hole in the plastic to mount the humidistat to the frame and a few other holes for the fans, exhaust, and humidifier hose.

Those are quart jars of (usually) rye, sometimes millet or WBS.  Those incubate for a while and are cased in the greenhouse or spawned to some other substrate.

His last batch was straw, but this time he cased straight grain. He'll probably spawn to straw again next time... depends...
