Changes to research plants: After an email from Atila, we will be monitoring the quinoa for sprouting.

Narrative: Renee was actively operating in the GreenHab monitoring her experiment. The NASA hardware that we have here at MDRS is a variation of flight hardware that has been on the ISS. I am continually in awe that I am taking part in research that has a direct impact on the future of spaceflight.

The Crew did a little re-potting of lettuce in the hopes that they will grow during our stay so that we can enjoy eating it. If not, future crews will enjoy the fruits of our labor, as we are enjoying the plants that other crews have planted for us.

Future needs and questions: We are awaiting the arrival of the tomato cages so we can replant the tall plants that require support to grow to their full potential. Please advise when they will arrive.
