Heating: 73 degrees F
Average temperatures (last 24h): 73.70 degree F
Maximum temperature (last 24h): 77.2 degrees F
Minimum temperature (last 24h): 70.2 degrees F
Hours of supplemental light: 2 hours
ON: 18:00 OFF:20:00
Daily water usage for crops: 1 gallon
Daily water usage for research and/or other purposes: No
Water in the Tank (160 gal useful capacity): 151 gallons remaining
Time(s) of watering for crops: 11:30
Changes to crops: No changes
Narrative: Sprayed liqui-grow onto vegetables, watered microgreens and plants. Massed microgreens prior to watering for data collection. After watering microgreens rather than just misting them, noticed 30% germination in the paper towel group, with the highest shoot being half a centimeter. Vermicular remains mostly ungerminated with the exception of 1 shoot, but also seems to retain water a little less, so I suspect it needs to be watered more to achieve results. Harvested mystery plant which we later used comms to identify as kale, a good burger addition.
Harvest: (include which crop and mass in grams) 29.27 grams of Kale harvested
Support/supplies needed: No supplies needed

Narrative: Sprayed liqui-grow onto vegetables, watered microgreens and plants. Massed microgreens prior to watering for data collection.

Time(s) of watering for crops: 15:30
Changes to crops: Replaced microgreen blackout lids with clear ones, since foliage has been found on both experimental groups.
Narrative: Sprayed liqui-grow onto vegetables, watered microgreens and plants. Massed microgreens prior to watering for data collection. 90% germination in the paper towel group, with the highest shoot being 2 centimeters. Vermiculite has over 50% germination, with most of the seeds being taller than the paper towel group.
Harvest:
Support/supplies needed: Microgreen SOP doesn’t cover protocol for transferring seeds from tray to soil. When should I do that? Additionally, the camera power cable is not in GreenHab, so while I’ve downloaded the app and everything, it can’t properly connect to the camera because it’s not turning on. Requested images of radish microgreen and setup are attached to this report.

Changes to crops:
Narrative: Sprayed liqui-grow onto vegetables, watered microgreens and plants. 90% germination in the paper towel group. Vermicular has now about the same germination, with the average height of the seeds being much taller than paper towel, the tallest being 4 centimeters. I think this is because the vermicular allows the seeds to stand upright, and the big disparity in results occurred after the switch from blackout to clear lids, which positively impacted the vermicular group a lot.
Harvest: No harvest.
Support/supplies needed: Microgreen SOP doesn’t cover protocol for transferring seeds from tray to soil. Can I take liberties to plant the vermicular group, or for experimental purposes should I leave them in the tray?
