Mushroom Grow Box
In an effort to increase mushroom yield, reduce maintenance, and improve environmental controls such as more stable humidity and fresh air exchange, we applied some basic programming, sensoring, and automation to a large clear tote and created an automated mushroom grow box.
The basic mushroom growing environment uses 3 simple principles and a few electronic components.
Cycle small fan to evacuate the air volume of the growbox, and draw fresh air in through a hepa filter.
Sample Humidity every 60 seconds.
Turn on a small fogger/humidifier until a humidity of 85% is achieved.
If this type of work is beyond the scope of your skills or abilities, the same system can be built with less technical components than those listed below. Although it wouldn’t be as precise, you could just use a mechanical timer to cycle a humidifier on and off a every other hour, or 30 minutes, and adjust the frequency and length of time the humidifier is on, based on the health of any mushrooms. Although you would have to open the lid occasionally to let in fresh air, as its important to mushroom growth.
