Crops seem to be responding well to the conditions. New growth on tomatoes and other plants is in good condition.
Narrative:
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.
