Environmental control: Heating. GreenHab door shade cloth (40%) (30%) on.

Average temperatures: 23.75°C

Hours of supplemental light: 19:30 to 00:00

Daily water usage for crops: 10 gallons

Daily water usage for research and/or other purposes: 0.5 gallons

Water in Blue Tank: 232.5 gallons

Time(s) of watering for crops: 3

Changes to crops: Ginger has sprouted! The wilty tomatoes look much better today after a healthy watering. Butter lettuce also has bugs so I gave it a little spray with the pesticide. One of the strawberry plants has flowered!

Narrative: I performed a moisture check on all the plant beds to give me a better idea of their water needs. The lettuce plants take up water quite slowly, whereas the herbs and the tomatoes require at least two waterings a day. Luis and I also checked on our Blue Corn experiment. Unfortunately the Martian soil is basically like cement or clay when it gets wet and so the corn is likely struggling. We’ve halved the soil samples and mixed half with Earth soil to see if that makes a difference. Maria and I are also planning a mungbeans experiment, looking at different Martian soil to Earth ratios to see if we can grow anything in the next week. We will set that up tomorrow.
