Sol: 6

Environmental control (fan & heater): Fan min 75F, max 80F
Average temperatures (last 24h): 81.5F
Maximum temperature (last 24h): 103.3F
Minimum temperature (last 24h): 59.7
Hours of supplemental light: 0
Daily water usage for crops: 0.1 gallons
Daily water usage for research and/or other purposes: 0
Water in the Tank (160 gal useful capacity): _159____ gallons remaining (system says 160 but I used some last night and the last few days it has been at 159)
Time(s) of watering for crops: 5 minutes misting the microgreen seeds for Spaceseed and MDRS microgreens
Changes to crops: Seeds have begun to germinate and show leaves in Spaceseed and in the MDRS microgreens experiment
Soil Moisture Level: 9.4 (Average of five points, one on each corner and center)

Green Hab Officer checked on both Spaceseed and the microgreens experiments, both of which are currently in trays that are stacked and in dark locations with weight on top of them to encourage germination. Spaceseed has started to germinate evenly across the top tray with leaves starting to show but the bottom three trays germination has only begun in locations where the ridges of the tray on top does not press into the seeds as strongly.

The microgreens with moist paper towels are not germinating, I believe due to the high temperatures. They would require watering multiple times a day which has not been the case. The vermiculite trays are all germinating with leaves beginning to form. They have been covered with clear tops and places on the wood pallet in the Green Hab. The two trays that were soaked with water are showing stronger growth than the two that were moistened.

Soil Moisture Level: 9.4 (Average of five points, one on each corner and center)

Green Hab Officer checked on both Spaceseed and the microgreens experiments, both of which have been removed from their stacks and laid flat side by side. The Spaceseed trays are within the cabinet and the vermiculite is on the wooden palette in the Green Hab. It was an exciting day as lots of green leaves have started to appear on both Spaceseed and the vermiculite trays. Green Hab Officer Mackenzie Calle misted both experiments with water and ensured both experiments are in good condition.

Changes to crops: Green leaves are growing strong on both the Spaceseed microgreens and the vermiculite wet trays. The moist vermiculite tray has some strong microgreens but some are turning brown.
Soil Moisture Level: 9.2 (Average of five points, one on each corner and center)

Green Hab Officer checked on both Spaceseed and the microgreens experiments, both of which have been removed from their stacks and laid flat side by side. The Spaceseed trays are within the cabinet still covered in their black cover and the vermiculite is on the wooden palette in the Green Hab covered with a clear top. The leaves are continuing to grow on both the Spaceseed trays and the wet vermiculite trays but they are not as strong on the vermiculite trays that had less water. Water levels of all experiments are continuing to be monitored.

Green Hab Officer unfortunately arrived at the Green Hab this morning to find the Spaceseed microgreens partially wilted. They had been growing stronger every day but either too much time was allowed or a temperature fluctuation has now made them inedible.

Narrative: I’m watering less considering the teardown, which we’ll get most of the way through tomorrow. We did a larger harvest so that we’d have necessary herb-age for the next two days.

Harvest: 150g of microgreens, herbs, and tomatoes

Support/supplies needed: Just wanted to make sure that the sun shades referenced in the GreenHab teardown report are the same ones folded up in the cabinet; perhaps they weren’t set up to begin with. If that’s referencing something else, just let us know!
