Mushroom Environment Control - Arduino Powered

Step 9 The Humidifier

To keep the temperature up you would plug in a beer heating pad (of course beer has to be involved).
To keep the C02 levels low you would add a fan.
...But what to add to keep the humidity up?? A humidifier and here's how I made mine.

First I got a small tub and drilled a number of holes in the top cover, and one bigger hole in the center. Next you thread the sonic humidifier wiring through and seat the humidifier on the bottom.
In one of the holes I attached some aquarium tubing.

On the other end of this tubing was an air pump held within a airtight tub. The lid of the tub had a hole cut out and was covered by a HEPA filter. The reason for the HEPA filter is so that air going into feed the mushrooms isn't contaminated with bacteria and other fungi.
This system of air filtration is also used for the air supply when the co2 gets too low.

After putting water in the tub, turn it on and watch.

Co2 too low??? You said "This system of air filtration is also used for the air supply when the co2 gets too low". Dont you want the co2 to be as low as possible?

Yes, it's meant to read "CO2 gets too high". The program switches the relay on when the CO2 level goes over a certain threshold. I just wrote the wrong thing and my editor didn't pick it up before it went to print.
