Crew 305 GreenHab Report 09Dec2024

GreenHab Officer: Hunter Vannier

Environmental control (fan & heater): Heater and fan on automatically.

Average temperatures (last 24h): 80 F

Maximum temperature (last 24h): 93.0 F

Minimum temperature (last 24h): 70.9 F

Hours of supplemental light: 1700 – hours

Daily water usage for crops: 2 gallons

Daily water usage for research and/or other purposes: None

Water in Blue Tank (200-gallon capacity): 168 gallons

Time(s) of watering for crops: 900, 1815

Changes to crops: None

Narrative: All cucumbers were very dehydrated so 1 gallon of water was distributed across the plants to thoroughly saturate the soil. The cilantro we picked was fresh and delicious, adding some color to dinner. Many of the herbs, radishes, and carrot seedlings are quite crowded, so I intend to thin them to ensure they have enough room/nutrition to grow. Next to the tomatoes, there are a lot of trays labeled microgreens which have turned into macrogreens and are likely no longer useable for food/salad (i.e. small sunflower plants). I intend to pull and discard half of them and seed new microgreens. These, along with the arugula, were quite dehydrated when I checked at 1815.

Harvest: 5 g cilantro

Support/supplies needed: none

Crew 305 GreenHab Report 10Dec2024

GreenHab Officer: Hunter Vannier

Environmental control (fan & heater): Heater and fan on automatically. I opened the door for 15 minutes to cool off the GreenHab; a lot of plants were wilting.

Average temperatures (last 24h): 82 F

Maximum temperature (last 24h): 94.6 F

Minimum temperature (last 24h): 68.2 F

Hours of supplemental light: 1700 – 2200

Daily water usage for crops: 5 gallons

Daily water usage for research and/or other purposes: None

Water in Blue Tank (200-gallon capacity): 163 gallons

Time(s) of watering for crops: 925, 1730

Changes to crops: significantly thinned carrots in back corner, thinned fennel, thinned radish, pulled whole bed of overgrown microgreens and replanted with China rose radish sprouts (4 g), broccoli seeds (2 g), red cabbage (2 g), radish (2 g).

Narrative: The cucumbers were fairly dehydrated again this morning, but seemed to bounce back better today. Three cucumbers per pot is quite crowded and they are competing too much for water, so I may try to transplant a few to larger pots to see how they react. Some tomatoes are also overcrowded. I did major thinning of the carrots in the back corner, which yielded a lot of carrot greens. They were too crowded to actually grow the carrot root, so hopefully they respond well. It seems a lot of seeds were planted but were not thinned early on, which is recommended for healthy growth. The radishes were much less crowded, but some thinning was still needed. However, the carrot greens and radish greens were made into a fresh salad and not thrown out. The cilantro, dill, and parsley are doing great despite also being fairly tightly grouped, so they respond much better when crowded. We added cilantro to a lentil dish for lunch which again was delicious. One raised bed of old microgreens was pulled, ~1 gallon of soil added, and replanted with the following microgreens: China rose radish, broccoli, red cabbage, and radish. I began soaking sunflower (3 g) and pea (3 g) seeds to be planted in the next 2 days in the other raised bed, which I will also pull. In the next two days, I plan on pruning the tomatoes and cucumber, harvesting arugula (which is also overcrowded), and transplanting sunflowers, tomatoes, and cucumbers.

Harvest: 5 g cilantro, 160 g carrot greens, 20 g radish greens

Support/supplies needed: none

Crew 297 GreenHab Report 20-04-2024

GreenHab Officer: Sean Marquez

Environmental control:
– Heater on (set to 55F)
– Fan on (set to 92F; not accounting for power outages)

Average temperatures: 84F

Hours of supplemental light: N/A

Daily water usage for crops: 4 gal

Daily water usage for research and/or other purposes: 0 gal

Water in Blue Tank: 183 gal

Time(s) of watering for crops: 14:05

Changes to crops: N/A

Narrative: Fan power went out again some time in the afternoon. Based on tests from the prior night, the fan power outages seem to be linked to the HomeAssistant network, which becomes unavailable during power outages. Between HabCom duties, lunch, and dinner preparations, I was unavailable to open the GreenHab door until around 14:04 (at which point the GreenHab atmospheric temperature had reached ~110F), then closed at around 19:25 when the GreenHab atmosphere temperature had dropped to ~80F. Brown/wilting leaves from the radishes were composted.

Harvest:
– 13g of cherry tomato
– 66g of red cabbage
– 147g of radishes
– 177g of kale
– 23g of green onion

Support/supplies needed: Would it be possible to run HomeAssistant on our other local network that is currently configured and powered via the UPS, so as to circumvent vulnerability to power outages? This change is minor and temporary and will be undone before the end of our mission.

Crew 297 GreenHab Report 21-04-2024

GreenHab Officer: Sean Marquez

Environmental control:

Heater on (set to 55F)
Fan on (set to 92F)
Average temperatures: 78F

Hours of supplemental light: N/A

Daily water usage for crops: 4 gal

Daily water usage for research and/or other purposes: 0 gal

Water in Blue Tank: 179 gal

Time(s) of watering for crops: 12:28

Changes to crops: Crops looking much healthier; minimal to no wilting compared to previous day.

Narrative: Fan power did not go out today, as the network on which the fan system controller running on HomeAssistant has been switched to the generator. Based on the recorded logs, the GreenHab atmospheric temperatures appear to not have exceeded 98F. Some brown leaves/stems from the cherry tomato plants were composted. Cucumber vines were found strangling its neighboring cherry tomato plants, which have since been separated and placed on an adjacent trellis.

Harvest:

106g of cherry tomato
Support/supplies needed: N/A

Crew 297 GreenHab Report 22-04-2024

GreenHab Officer: Sean Marquez

Environmental control:

Heater on (set to 55F)
Fan on (set to turn on at 94F; turn off at 82F)
Average temperatures: 82F

Hours of supplemental light: N/A

Daily water usage for crops: 4 gal

Daily water usage for research and/or other purposes: 0 gal

Water in Blue Tank: 175 gal

Time(s) of watering for crops: 12:50

Changes to crops: N/A

Narrative: Fan system was operating nominal. Though, due to the afternoon heat wave, the GreenHab atmospheric temperature reached close to 110F around 14:30. The GreenHab door was opened again to allow for supplemental airflow from the tunnel system, which helped keep the atmospheric temperatures below 100F. More brown/yellow leaves/stems from the cherry tomato plants were composted.

Harvest:

2g of cherry tomato
Support/supplies needed: N/A

Crew 297 GreenHab Report 17-04-2024

GreenHab Officer: Sean Marquez

Environmental control:
– Heater on (set to 55F)
– Fan on

Average temperatures: 91F

Hours of supplemental light: N/A

Daily water usage for crops: 5.25 gal

Daily water usage for research and/or other purposes: 0.25 gal

Water in Blue Tank: 191 gal

Time(s) of watering for crops: 11:34, 12:33, 15:18

Changes to crops: Carrots, radishes, and red cabbages were looking wilted. Two of the (Riya & Garbanzo) kale plants were looking less wilted compared to the prior two days.

Narrative: Crops that were wilting today were likely due to EPS fluctuations, causing inconsistent air flow from the fan system in the GreenHab throughout the day. While watering the plants around 15:18, the GreenHab temperature had reached 110F. In an attempt to supplement the lack of air flow and reduce heat build up in the GreenHab, the door was opened around 16:00 to allow for the tunnel system to act as a temporary air conduit, at least ’til around sunset when the door was closed.

Harvest:
– 288g squash
– 2g cherry tomato

Support/supplies needed:
– (more of a nice to have, but) a means to query and download the GreenHab atmosphere temperature data from HomeAssistant as to be able to perform time-series analysis, automation of calculating average temperatures, and/or for comparison with the FPrime data collection system.
