Narrative:

After the morning EVA, I harvested some herbs for our lunch and some carrots for our dinner.

In the afternoon, I prepared the soil for the next tomatoes seeds and removed the old ones.

Finally, I monitor the fan in the Greenhab to avoid high heat in the morning. It will now be turned on from 8 to 16, for 15 min every 15 min. It worked pretty well today!!

The door was opened from 0730 to 1700.

Harvest: 8.1 g of basil, 1.3 g of sage, 270.6 g of carrots.
