Crew GreenHab Officer Daily Report
Sol # 10
Crew # 161
Crew GreenHab Officer: Natalia Glazkova
Watering duration: once a day in the morning. Moisture level of the soil in the evening 33%.
Light exposure: 18h per day (7.00-24.00)
Morning temperature: -
Evening temperature: 20ºC
Height lamp bulbs to plant: 17’’
Several hypotheses for reduced sprouting success (of both beans and radish) in the 30/70 soil mix:
Long term exposure to the UV light could be the reason of the yellowing leaves.
I plan to reduce the time of exposure to the UV light down to 15 h per day and will keep the moisture level of 25%. I also planted rest of the beans today (soil samples #6,#7; mix ratio: 50/50, 30/70), so we will have a chance to see whether the changes would affect the plants.
I was not planning to transplant the seedlings to the bigger pots. Due to the instructions received before the mission, I suppose to dispose the material at the end of the rotation.
