Narrative: The handoff from Crew 184 went very well yesterday. Thank you to the Green Hab Officer David for walking me through the experiments.

Today I watered the crops whenever there was a break in crew training. The beans and radishes are near harvest. There are +20 tomato, +10 cucumber, and various other plants in intermediate growth stages.

I’ve built a device to log temperature and humidity continuously throughout the day using an Arduino, DHT11 sensor, and an SD card shield. The device has been running all day and will continue to record through the night to determine the maximum battery life.

Tomorrow I will create a complete inventory of the crops and current experiments. As well, I will prepare the East half of the Green Hab for my experiments with microgreens.

Support/supplies needed: Potting soil needed.

Happy New Year!

Mark Gee, Green Hab Officer, Crew 186
