Crew 281 GreenHab Report 16 May 2023
GreenHab Officer: Megan Kane
Environmental control: fan with door open
Average temperatures: 84.38
Hours of supplemental light: None
Daily water usage for crops: 0.66 gallons
Daily water usage for research and/or other purposes: NA
Water in Blue Tank 175.91 gallons
Time(s) of watering for crops:
0730: refilled one water bottle (500 mL) watered other plants as needed 1 L
1810: refilled 1 water bottle (500 mL) watered other plants as needed 500 mL
Changes to crops:
Crops seem to be responding well to the conditions. New growth on tomatoes and other plants is in good condition.
In the morning the greenhab was checked and watered as required. It was noted that water in planters had to be added little by little to ensure water was absorbed into the soil. Will survey more closely to determine if perforation of the soil would be helpful to water absorption and retention.
Trained 2 crew members on Greenhab startup procedures.
For two hours this afternoon a test was conducted to see if the greenhab operation remained constant or was improved by turning up the fan and closing the door to allow the louvers to open. The test showed that the temperature and humidity conditions in the greenhab were stable with the door open or closed as long as the fan was on.
Crew engineer created an airflow diverter out of cardboard for the fan to reduce the intensity of the airflow on the plants directly in front of the fan. Diverter was completed at approximately 6 pm. Will test its effectiveness tomorrow.
