Daily water usage for crops: 0.1 gallons

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.
