In the event that the chamber will not be used for a period of up to and including 14 days, it is
best to keep it running, with the temperature at or near ambient and with only the fans running.
If experiments will not be run for a period of longer than 14 days, to minimize unnecessary
electricity consumption, ensure all plants and soil are removed from the growth area, and clean
the unit as described in the Conviron Chambers Maintenance & Troubleshooting Manual. Open
the fresh air inlet and exhaust ports and leave the chamber and observation doors slightly open
to reduce moisture buildup.
