Narrative:
This morning, we harvested some mixed green salad and radishes for Aurélien’s birthday. We also prick out the 8 radishes pots of my experiment, to allow the best radishes to grow;

In the afternoon I performed my experiment in the greenhab, placing each pot in the growtent, with UV light and specific music for 6 minutes. However, the UV lamp found in the science dome doesn’t seem to be powerfull enough, I think it won’t be good for the experiment.

Other problem we faced today : the heater thermometer is placed on the cooling fan’s metal side. When it is hot, we put on the fan, so the heater thermometer decreases a lot more than the greenhab, and its temperature reaches 15° while it’s 25° in the greenhab, so the heater turns on.
Today, both the fan and the heater were turned on, although the temperature was high (31°C). We should re-monitor the heater thermometer.

Harvest: 89 g of mixed green salad, 1 g of watercress and 35 g of radishes.

Support/supplies needed: None.
