Green Hab Officer completed Spaceseed setup evening of Sol 3. The structure was completed earlier in the evening and then the final technology and software was completed prior to installing the microgreens on the rockwool trays. We believe the system is properly connecting to the PIs but it did need to be unplugged and re-plugged into a new power source. From our end everything is nominal but awaiting confirmation.
The microgreens research experiment has also begun comparing vermiculite to a wet paper towel base. Broccoli, radish, mung bean, and alfalfa sprouts have all been planted and we will monitor growth over the next 8-10 days.
