Narrative: Some of the tomatoes looked a little wilted so I made sure to give them extra water today. I went back and checked on them a few times and they plumped up by the EOD. The sunflower and pea transplants are both looking healthy and happy. The carrots and tomatoes are getting pretty sizable, they will be ready for the next crew.

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

Time(s) of watering for crops: 8:40 am, 2:44 pm
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

Changes to crops: Removed 14g of cucumber leaves
Narrative: I inspected the cucumbers very closely today, we have four that should be ready to harvest in the next 1 to 2 days. I thinned out a few of the carrots and chopped them up for our chickpea curry dinner. I went out pretty late to give the plants their evening watering and one pot, an arugula pot, was not happy at all. It was very wilty so I gave each of them a ¼ gallon of water. I had everyone try the arugula because it is mature and a little spicy for my taste, I want to find a good use for it before I decide to change it out for a different plant. A sunflower is getting close to blooming.
Harvest: 14g of Carrots, ~1 gram of Arugula

Narrative: The HSO and I went out to the GreenHab this morning to harvest some Thyme and Scallions for Lunch. Everything looked good this morning. I also harvested 5 cucumbers for our morning snack and dinner. At dinner time I harvested the remainder of the broccoli microgreens. The sunflower started blooming today. Tomorrow I plan on harvesting arugula and basil and moving the pea and sunflower sprouts to bigger pots if it is cloudy.

Time(s) of watering for crops: 7:50 am, 6:02 pm

Changes to crops: None

Narrative: In the morning, there was no cucumber wilting, but by 6:00 PM they were quite wilted despite their soil still being damp. This is consistent with the weather being very sunny with no clouds and a high of ~95 F in the GreenHab, in contrast to yesterday’s weather (overcast) and the plant conditions (not wilted). I am going to water only two of them to see how well they recover with/without water given the cooler temperatures at night. All the tomatoes are still doing great.

I am happy to report the water monitoring system will be up and running tomorrow morning thanks to a soldering tutorial from the engineering-minded crew members; I had a lot of fun. I will also end the blackout period for the peas and sunflower microgreens tomorrow.

Harvest: none

Time(s) of watering for crops: 10:16 am, 4:30 pm

Changes to crops: Removed blackout cover for peas and sunflowers

Narrative: The two cucumbers I watered last night are a bit less wilted, but not much. The plants closest to the eastern wall of the GreenHab seem most affected. Regardless, they are staying green and not dying, so I think I will relax finally about the wilting situation and accept that they should always get a morning and evening watering. Excitingly, there are some baby cucumbers growing (~1 cm) that have gotten larger than the withered ones I observed last week, so hopefully they will continue to mature.

My recommendation for the arugula, sunflowers, and tomatoes is to just water them when they start to wilt because they bounce back quickly and don’t need water every day at this point.

I removed the blackout cover from the sunflower/pea microgreen bed and one sunflower is starting to sprout.

On a research front, I have started my soil moisture monitoring experiment. The soil moisture sensors are giving data, and I took multiple data points today to make sure they are working. Because of the small pots I’m using, the moisture sensor needs to be off the bottom of the pot and closer to the surface to get a consistent reading. Because I primed the soil yesterday, it wasn’t completely dry to start, but that should be accounted for based on the initial measurements prior to watering.

Changes to crops: harvested cilantro

Narrative: The thyme has shown significant growth in the past two days, and the herbs generally keep proliferating. The cucumbers enjoyed their morning and evening watering, though it seems the cucumbers that are in contact with the east wall of the GreenHab are more prone to withering; there are a few yellow leaves near their base. A lot of radish microgreens are sprouted and can be harvested soon. A few more sunflowers sprouted, but the pea shoots have still not made a full appearance. These will likely be enjoyed by the next crew rather than ours. We harvested 20 g of cilantro, 10 for lunch today (black bean burger burritos) and 10 g for dinner (Jambalaya).

Changes to crops: harvested cilantro

Narrative: The crops are doing well today; I have a well-established watering schedule for the current crops in the GreenHab that I will include in my final report. One of the cucumbers is about 4 inches long! It will be ready to be harvested soon, hopefully before we leave. The microgreen raised beds continue to make progress, but not enough to harvest yet. The soil moisture experiment looks more promising, as the microgreens’ growth rate seems to be significantly impacted by the water content, which I hope is reflected in the soil moisture measurements. The arugula should be harvested ASAP; it is not growing any larger and wilts quickly. I might pull a couple containers before I leave to improve water efficiency. 8 g of cilantro were harvested to be used in our chicken curry dinner.

Harvest: 8 g cilantro
