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.

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

Changes to crops: Harvested one Sunflower
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.

Narrative: Today was a very productive day in the GreenHab. I swept and got 6 pots ready for sunflower sprout transplants. One of the peas didn’t make it, I am going to wait for the other peas’ sprouts to get stronger before transplanting another one. I noticed that two tomato plants were missing tomato cages so I put tomato cages on them. There were 3 ready cucumbers so I harvested those and some cilantro for tonights dinner. Yesterday we harvested dill for dinner.

Changes to crops: Harvested two pots of broccoli microgreens
Narrative: Today was my first day as GreenHab Officer! It was a great first day of familiarizing myself with all the plants, they all looked so happy. I noticed that the humidity was below 80% so I decided to fill the spray bottle and give all the plants a nice mist. In the future I will do this when the sun rises. While checking the tomatoes I noticed there were a lot of suckers or small sprouts growing in between the fruiting limbs and I plucked them all off. In total I removed 10 grams of tomato biomass. I also hand pollinated about 5 flowers on each cucumber plant using q-tips form the science dome. I plan on removing flowers from the cucumber plants to encourage stronger fruit. I harvested two broccoli microgreen pots and ~ 6 radish leaf greens for dinner. I

Harvest: 32g of Radish greens and 14 g of broccoli microgreens

Changes to crops: None
Narrative: After watching the sunrise, the plants got a nice misting. I checked the moisture level on the plants, and everything was moist but the cucumbers, so I gave them good water. I also decided to pour a gallon of water on the ground to see if it would help with the humidity. I went back to check and most of the water had evaporated, and the humidity was above 40%, much higher than the usual 20-30%. On today’s lunch menu, spaghetti, garnished with basil! I chopped up a few grams of basil and thyme and carefully selected 6 basil tops for our spaghetti plates. In the afternoon, the crew geologist and I went out to the GreenHab to inspect the radishes and by inspection, I mean taste. We are cooking up a plan for them. There are some sizable cucumbers as well, they seem much happier with the higher humidity. I brought some CO2/Humidity/Temperature sensors with me and left mine in the GreenHab to compare with the monitor already in the GreenHab. My values are higher than the values being recorded by 3 to 5 digits for both the humidity and the temperature.
Harvest: 7g of Basil, ~1g of Thyme, 14g of Chinese Rose Radish
