Time(s) of watering for crops: 9:30 am
Changes to crops: None
Narrative: I spent my last day cleaning up the GreenHab and saying goodbye to all the plants. What a wonderful experience this was! Everything looks happy and healthy. An abundance of crops is coming for future crews including carrots, cucumbers, tomatoes, peas, and a plethora of herbs. Nothing tastes better on Mars than fresh greens.

Water in Blue Tank (200-gallon capacity): 125 gallons
Time(s) of watering for crops: 11:30
Changes to crops: None
Narrative: Sunflower and pea sprouts are looking healthy still. The tomatoes looked like they needed more water again so I gave them about 3 gallons total. I have determined it is from underwater because they look better a few hours after watering. When tomato plants start fruiting they generally need less water but they are in pots that are too small and will need to be transported to 4 – 5 gallon containers. I checked one of the carrots today that was peeking out of the soil. It measured ~ 6 inches and weighed 14g. It was a beautiful purple carrot! In the next few weeks there should be plenty of carrots ready for harvest.
Harvest: 14 g Carrot.
Support/supplies needed: None

Changes to crops: Removed 73g of dead cucumber leaves
Narrative: We had our first sunflower bloom! It was very pretty and the other two will soon follow. I pulled a few side shoots off of the main tomato plants. In the future I plan on putting these into small pots to continue the cycle of tomato plants. I pulled off a lot of dying leaves from the cucumber plants. I harvested a lot of arugulas from one of the pots for dinner and made a significant dent in the amount that was growing in the pot. I got busy today with experimental procedures, so I was unable to replant any pea shoots. I have decided I will only change one pot.
Harvest: 189g Arugula, 24g Basil

Narrative: I watered everything in the GreenHab today. There were no harvestable edible crops. The peas are doing well after the transplant. I cut down one sunflower and I am going to move some sunflower sprouts to bigger pots. I moved a humidifier to the grow tent in the science dome to up the humidity for the mushrooms. The humidity got up to 98% which is ideal. This will encourage mycelial growth.

Yesterday we harvested dill for dinner.
