In the growing modules two bed temperature probes, each inserted in the middle of a rack monitor the bed temperatures in the racks. These are alarmed for high and low temperature. The relative humidity is calculated from a wet and dry bulb thermistor with the dry bulb alarmed for high and low air temperature. The humidity is monitored by the control computer and the humidifier switched on or off as required. The vertical growing method produces mushroom bunches ready for harvest with virtually no stalks.
Picking is by twisting the mushroom bunches off and trimming the short stalk.
This leaves a clean substrate surface ready for the next flush. The picking process is very simple and requires little cleanup of the mushrooms after picking, they are picked directly into the delivery boxes. For a continuous even supply, three growing modules are required and the modules must be loaded with the correct time spacing. Because the system is extremely clean very little bacteria are present on the mushrooms giving a shelf life up to a week. Because no pesticides or chemicals are used in the growing process, the mushrooms have organic certification.
