GreenHab Report – February 11th

Crew 221 GreenHab Report 11FEB2020

GreenHab Officer: Jessica Todd

Environmental control: Heating. GreenHab door shade cloth (40%) (30%) on. Door opened today from 12:15 pm to 4:06 pm.

Average temperatures: 22°C

Hours of supplemental light: 19:30 to 00:00

Daily water usage for crops: 15.85 gallons

Daily water usage for research and/or other purposes: 0.53 gallon

Water in Blue Tank: 178.8 gallons

Time(s) of watering for crops: 2

Changes to crops: We have a cucumber! The zucchinis and cucumbers are flowering, and the strawberry plant has begun growing a strawberry. The tips of the narcissus are incredibly dry and browning. They have been watered regularly so I’m concerned the heater is drying them out. Should we move them to a lower level?

Narrative: Today was exciting as we harvested quite a bit from the GreenHab on Shannon’s recommendation for tonight’s dinner. Rosemary potatoes and salad! We are feasting like kings! The plants were watered this morning and this evening, and excitingly one of our Blue corn plants in Martian soil has begun to sprout. That’s right; Crew 221 has officially grown crops on Mars.

Harvest: 71g Cucumber, 20g lettuce, 6g butter lettuce, 14g onions, 4g rosemary.

Support/supplies needed: NA

Other Notes: Myself and the Crew Engineer noticed the water level in the GreenHab tank is much lower than expected. The water has just dropped below the level of the upper tap, meaning it is around 1/3 full (~100 gallons). We have been basing our water amount each day on subtracting the amount used every day from a full tank at the start of Sol 0. Due to the busy schedule of Crew 220, and the repairs being done by David and Atila, Crew 221 did not complete all the water refilling of the station prior to the start of our mission, and the GreenHab tank had to be refilled by Atila on Sol 1. We were told the GreenHab tank was filled to full (300 gallons), however we have kept a careful record of our water usage, and while our numbers tell us we should have 178.8 gallons, this is clearly not the case. We should have sufficient water in the GreenHab to get us to the end of our mission, however it will be cutting it close.

GreenHab Report – February 10th

Changes to crops: Same as yesterday: Pumpkin plants are flowering nicely. There are a number of soil-filled pots on the bottom level of the central shelf. They are labeled as bell peppers but in one week of monitoring I’ve seen no sprouting. I don’t think there are any plants in these pots.

Narrative: Once again it was a pretty hot day in the GreenHab so we opened the door for a few hours. Morning watering was uneventful; all the plants are doing well. Our Mars corn is starting to sprout (yay!), still waiting on our mungbeans. We harvested some yummy chard spinach and chives for our quinoa salad (finally getting some greens!).

Harvest: 9g Chard Spinach, 10g Rocket, 2g Chives, 3g Corriander

Time(s) of watering for crops: 2

Changes to crops: Pumpkin plants are flowering nicely. There are a number of soil-filled pots on the bottom level of the central shelf. They are labeled as bell peppers but in one week of monitoring I’ve seen no sprouting. I don’t think there are any plants in these pots.

Narrative: Watered the plants this morning at 9:43am. Today was a little colder so we kept the GreenHab toasty this morning and opened the door for a few hours around lunch. We had omelettes for breakfast so harvested some lovely spinach and rocket to get some greenery! Our mungbeans and blue corn have yet to sprout but will continue to monitor.

Harvest: 9g Chard Spinach, 3g Spinach Lakeside, 6g Rocket

Support/supplies needed: NA

Other Notes: NA

Greenhab Report – February 08th

Crew 221 GreenHab Report 08FEB2020

GreenHab Officer: Jessica Todd

Environmental control: Heating. GreenHab door shade cloth (40%) (30%) on. Door opened today for four hours from 2:45 pm to 6:52 pm due to very warm weather.

Average temperatures: 24.33°C

Hours of supplemental light: 19:30 to 00:00

Daily water usage for crops: 14.7 gallons

Daily water usage for research and/or other purposes: 1 gallon

Water in Blue Tank: 227.3 gallons

Time(s) of watering for crops: 2

Changes to crops: One of our succulents has died (picture attached). I managed to rescue three out of five, waiting on one, but sadly the other one is completely dead. Rest of the GreenHab looks really healthy, including the tomatoes. Ginger plant going strong and we have some new bell peppers and lettuce sprouting!

Narrative: Morning watering was a little late today due to the early EVA, but plants all look really healthy. Commander Maria and I set up a new experiment in the GreenHab, attempting to grow mungbeans in different ratios of Earth and Martian soil. We have several beds of mungbeans growing in 100% Earth Soil, 100% Martian Soil, 50%/50% Martian/Earth Soil and 70%/30% Martian/Earth soil. We will be monitoring the soil pH and nutrients to see if the Earth soil can populate the Martian soil with some healthy bacteria (Mark Watney style!). Evening watering was uneventful, all the plants save the succulent look pretty healthy. We should be ok to harvest herbs again tomorrow.

Harvest: NA

Support/supplies needed: NA

Other Notes: Sprayed one of the lettuce plants with pesticide. The bugs seemed to have fled the sprayed herbs and onto the lettuce. The lettuce plants in the hanging Ikea pots are having trouble with over-moist soil, as the pots have no drainage. Am I able to mix some perlite in with them to help absorb up the water? Also should I fertilize the plants at all while I’m here?

 

GreenHab Report – February 7th

Crew 221 GreenHab Report 07FEB2020

GreenHab Officer: Jessica Todd

Environmental control: Heating. GreenHab door shade cloth (40%) (30%) on.

Average temperatures: 23.75°C

Hours of supplemental light: 19:30 to 00:00

Daily water usage for crops: 10 gallons

Daily water usage for research and/or other purposes: 0.5 gallons

Water in Blue Tank: 232.5 gallons

Time(s) of watering for crops: 3

Changes to crops: Ginger has sprouted! The wilty tomatoes look much better today after a healthy watering. Butter lettuce also has bugs so I gave it a little spray with the pesticide. One of the strawberry plants has flowered!

Narrative: I performed a moisture check on all the plant beds to give me a better idea of their water needs. The lettuce plants take up water quite slowly, whereas the herbs and the tomatoes require at least two waterings a day. Luis and I also checked on our Blue Corn experiment. Unfortunately the Martian soil is basically like cement or clay when it gets wet and so the corn is likely struggling. We’ve halved the soil samples and mixed half with Earth soil to see if that makes a difference. Maria and I are also planning a mungbeans experiment, looking at different Martian soil to Earth ratios to see if we can grow anything in the next week. We will set that up tomorrow.

Harvest: NA

Support/supplies needed: NA

Other Notes: N/A

 

GreenHab Report – February 06th

Crew 221 GreenHab Report 06FEB2020

GreenHab Officer: Jessica Todd

Environmental control: Heating. GreenHab door shade cloth (40%) (30%) on.

Average temperatures: 18.33°C

Hours of supplemental light: 19:30 to 00:00

Daily water usage for crops: 9.2 gallons

Daily water usage for research and/or other purposes: 0.5 gallons

Water in Blue Tank: 243 gallons

Time(s) of watering for crops: 1

Changes to crops: Two of the four succulent plants seemed to have recovered a bit, yay! The leaves are more plump. Waiting on the other two. I repotted one of the sadder looking ones, as the soil was completely dry and barren and the roots didn’t seem healthy. Hanging lettuce pot on the bottom was fully soaked in water. As the pot has no drainage, will leave lettuce unwatered for the next day in the hopes that the soil dries out a bit. A few tomato plants are wilting. Rotated the plants on the bed. Ginger has almost sprouted, and the radish sprinklers, bell peppers and roma tomato have all sprouted.

Narrative: The plant beds were very moist this morning so I skipped the morning watering. Crew Engineer and I set up a new experiment in the GreenHab. We are going to attempt to grow Blue Corn from Martian soil! We have set up four trays on one of the benches, one as the control and three containing different types of Martian soil, mixed with some fertilizer. We’ve planted several rows of blue corn and will be watering it and monitoring the soil conditions each day.

Harvest: NA

Support/supplies needed: NA

Other Notes: Have sprayed the herb garden and the carrots and icy radishes with some pesticide to get rid of the small bugs. Will not harvest for the next few days. Also, slightly concerned about the wilty tomato plants. I have no experience with tomatos. Would this be a symptom of too much/little water? Or too much/little sunlight?

Narrative: Crew Journalist Hemani took over morning watering today as the GreenHab Officer was off on an early EVA, collecting soil for some botany experiments. We harvested some butter letter and lettuce for our Mexican dinner feast! Evening watering was good, gave the plants a healthy watering as the soil was very dry for a few of the beds.

Harvest: 7g Butter Lettuce, 11g Lettuce

Support/supplies needed: NA

Other Notes: Watered the succulents and aloe. They don’t look any worse but not much better either. I would love some advice on how to help these succulents recover. Photos of the strawberry plants are attached to this email. As we were using the herbs and lettuce tonight for dinner, will spray the bug-infested beds tomorrow with the pesticide.

Narrative: A morning water before our maintenance EVA today. I watered a few of the herbs again in the middle of the day per Crew 220’s instructions. When watering tonight I noticed quite a few plants were dry, so perhaps too hot in the GreenHab today. We might need to open the door tomorrow for a bit to keep the temperature even. We harvested some cilantro to have with our green curry for dinner tonight.

Harvest: 3g Cilantro

Support/supplies needed: N/A

Other Notes:

Aloe and succulents unchanged. Will water again tomorrow. The strawberry plant leaves are browning and rotting at the edges. From the information sent through in yesterday’s comms window, this may be an indication of black root rot or verticillium wilt. I think I will need to check the roots tomorrow for indication of black root rot. Am not sure how to proceed in rescuing these plants. Also noticed a number of small insects around the herbs, carrots and radishes. Should I spray with pesticide?

Narrative: Its Sol 1 and as today was a day packed with EVAs so plant duty was mostly just watering and checking on the status of the strawberries and succulents. I was hoping that after their deep watering last night I would find the succulent leaves nice and distended with water, however they still look a little limp. I’ve watered again, hopefully the next few days will see the succulents revive a little. Tomorrow we’ll be starting to look at growing some of our own plants for the duration of our MDRS mission. Looking forward to harvesting some of the delicious herbs for dinner tomorrow!

Harvest: N/A

Support/supplies needed: N/A

Other Notes:

Aloe and succulents on upper shelf below the heater are still dry and not distended. Gave another healthy watering, and will continue to monitor.
