Narrative: Julia showed Zac and I which plants to trim and move. We spent time working on the NASA VEGGIE OASYS plant growth prototype hardware which we have relocated to the west corner shelf of the GreenHab. We took photographs for the scientists at Kennedy Space Center. The final fill amounts for the reservoir chamber in the unit was 2200 mL of water and each seed pillow was filled with 100 mL of water to start. We will be growing Italian Basil and Salad Bar Lettuce. We were excited to share our progress with Julia when she returned from her EVA trek!

We spent some time trimming back the dead leaves on the plants on the west shelves and propping up some of the drooping tomato plants. I believe there is a plan to obtain more tomato cages which is needed for the high volume of tomato plants being grown.

Lastly, we moved the existing sun shade a little lower down to provide the plants in the middle and east sides of the GreenHab more relief from the direct sunlight.
Future needs and questions: Is there a plan for ordering an additional sun shade? We also need additional tomato cages. We received the gardening gloves. Thank you!!!
