Narrative: Both Julia and Zac were on EVA’s today at separate times and both spent time watering the plants, staggered. Upon persistent trials and errors, we have both noticed that the wilted plants are most likely due to requiring a midday watering, being dry from having the door open, and being in the southwestern-most corner (and getting very hot).

We will keep monitoring and testing out better methods to keep the temperature not too hot and not too cold. Today was a very windy day.

Future needs and questions: We need tomato cages before repotting as to not disturb them any more than necessary.

Summary of NASA VEGGIE OASYS: Renee added water to the wicks and the reservoir and took photos of germinating seeds for the PI.
