Average Temperatures:
Low: 24 C
High: 50 C

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.

Hours of Supplemental Light:

Daily Water Usage of Crops:

Water in Blue Tank (lbs):
28%

Times of Watering for Crops:

Changes to crops:
Planted 6 small areas of sunflower seeds
Planted 6 small areas of alfafa seeds
Harvested 69 g of mixed salad greens

Narrative:
Decided on format for outreach experiment, planted the sunflower seeds
and alfalfa. Last day with the full crew, so we are having a fresh
salad!

Harvest:
69g mixed salad greens

Support/Supplies Needed:
One of the raised beds of mixed salad greens is having some wilting,
while the one I harvested is thriving. I’ve been watering both the
same, but it seemed to be showing signs of this for the past week.
I also need a more accurate way to take the height of the water level.
It is hard for me (and even another crew member) to tell the level
just from tapping it. A level sensor or a pressure sensor would be a
good addition to the Greenhouse.
