Temperatures: 81.4 F

Hours of supplemental light: N/A

Daily water usage for crops: 14 gallons

Daily water usage for research and/or other purposes: 0.25 gallons

Water in Blue Tank: 169 gallons

Time(s) of watering for crops: 08:30, 17:00 h

Changes to crops: seed tomatoes are cultured

General watering of plants and crops was done today. There was high wind therefore the door was closed almost the whole day. Two experiments have started.

1- Tomatosphere
Principal investigator (PI) researcher: Ari Farrés
Supervision: Laia Ribas
Procedure: Two sets of tomato seeds have been planted. The first set (control) has always been on Earth, and the second set has experienced different radiation exposure, as they have spent some time in outer space. The goal of the experiment is to compare the growth of the two sets of seeds and see if we are able to determine which ones have been in space. We currently do not know which of the two sets has been in space.

2. Seeding for the crew
Principal investigator (PI) researcher: Laia Ribas
Procedure: The aim of the project is to provide fresh food to the crew. A total of 75 g of three bean Mix Nature Jim’s Sprouts have been cultured. For 5 hours the seeds were watered. Following that, the water was discarded and the seeds were cultured in wet tissue paper in a plastic box half covered.

Harvest: 190 g cucumber

Support/supplies needed:
I would like to get instructions on what is the best procedure to follow if there is a windy day with high temperatures as the door can not be properly subjected within the current format.
I noticed that the two thermometers of the Greenhab are not in concordance.
