October 30th // Heating Issues

Hugo Saint-Louis

Looking at the climate data of the past week, we can observe that the cold nights of the past week has been affecting certain zones of the greenhouse differently. We noticed that Zone 4 was getting about 2° colder than the heating setpoint of 19°. To help alleviate some of these issues, we have decided to turn of bench heating in Zone 4 back to a 19° setpoint.
