Hours of supplemental light:
For the crops 05:00 to 11:59 PM
Changes to crops: The tomatoes, cucumbers, beans, herbs, peppers, and melons keep growing. The microgreens have taken off and will be ready to harvest tomorrow. Of the seeds planted, the arugula, mustard, and various lettuce varieties have sprouted.
Daily water usage for crops: 15 gallons
Time(s) of watering for crops: 11:00AM, 06:30PM
Research observations: The microgreens have recovered from the early damage and are sprouting magnificently. Tomorrow they will be harvested.
Changes to research plants: None.
Aquaponics: Not in use.
Narrative: Today I watered the plants as usual and inventoried the tools, fertilizer, pots, and supplies.
The grow lights turned on at 02:00 pm. The analog timer has been gaining time steadily, as do the clocks on the electronic appliances in the Hab. These clocks probably use the frequency of the alternating current power supply to keep time as is common in most appliances. The standard frequency for an electrical grid in the US is 60 Hz, and our crew engineer observed that the generator is supplying power at 60.18 Hz. This increased frequency would cause the clocks to gain time at approximately the rate we are observing. See Sol 1 summary for a further explanation.
To compensate for this gain, the light timer needs to be reset every day.
Support/supplies needed: Scale with a capacity of 2 kg. The analog scale in the Science Dome has a capacity of 610g. Needed for experiments tomorrow.
