Changes to crops:
Tomatoes keep growing. 2 of the pots present the best performance.
Baby greens growing good, but one of the flats is not presenting good progress.
Cucumbers growing a little bit slow.
Lettuce starting to grow in good shape. Will keep track of them.

Narrative:
Temperature is growing a lot, we need to adjust down the heater.
Heavy water to all plants today. Humidity overal is a little bit low, maybe due to the increase of temperature.
I think that shade can be reduced a little bit (maybe to 30%)
Salads and raddishes looking in great shape! Will do an amazing meal for Christmas

Harvest:
NONE

Support/Supplies Needed:
Due to the increase of weather temperature, we need to adjust the heater to reduce the temperature around 20-25%. Can I do it by myself, or I can get some help on that?
I recovered our first soil samples today on the EVA. I’ll start with my soil mix tomorrow, with a 30% of sample + 70% garden soil.

Hi Atila,

Thank you for the question. Tomorrow early we will check if restarting the thermometer gives different measurements. The ones we are recording are the whole day temperatures. Can you give some advice about the situation?

Shannon gave a great suggestion to start mixing the organic materials with the soil samples. I’ll gather the first samples tomorrow to start the testing.
I’m starting with a 70% growing soil + 30% sample soil to grow some seeds. Any suggestion on which seeds should I try?

Hours of Supplemental Light:
5

Daily Water Usage of Crops:
8 gallons

Water in Blue Tank (lbs):
67%

Times of Watering for Crops:
1600

Changes to crops:
NONE

Narrative:
The high measurement was still 50 today, but since I wasn’t at the
greenhab at the highest time in the day.

Harvest:
1.6 g of Sage
95.8 g Sunflower Sprouts
37.8 g Mixed Salad Greens
4.4 g Cilantro
6.4 g Water Cress

Support/Supplies Needed:
Was there suppose to be a weight in the GreenHab? If so, I cannot find
it and have to go to the Science Dome to get the mass of the harvest.
GreenHab is a great place to work, it has alot of potential. With
added sensors and automated suns shades, the Hab GreenHab can become
closer to the type of system we’d want on Mars!

Narrative:
The weird 54 C reading was a trick of the light, literally! I moved it
closer to the center of the hab, away from direct sun. I also tested
with an analog thermometer.

Harvest:
NONE

Support/Supplies Needed:
It would be interesting to sees the O2 ans CO2 levels throughout the
day. It would be an important measure to have on Mars! If you can, I’d
love suggestions for sensors.
