Narrative:
– The greenhab was opened at 10 am. Environmental measurements of temperature and relative humidity were taken in the morning and in the afternoon at 18:05p.m. Crop inventory begins. Tomato cultivation was found distributed in 3 units. In one of these a slight growth is evident. In the others, no growth is evident.
There is a cultivation of Lettuce, thyme, chires, cilantro, cucumber, carrots. At the moment there is no evidence of germination. Radish harvest begins.

Support/supplies needed:
– Authorization and instructions are requested to operate the supplemental light times. Please
– The largest blue tank does not show any identification or crop labels present. Please confirm if this terrain can be planted.
– There is no evidence of the existence of the GreenHab notebook, please provide or indicate instructions to register the data during crops.

Narrative:
As this is the final day of the season the greenhab was opened in the morning. Everything edible was harvested. Then the biomass was placed into trash bags. Once the primary biomass was removed the roots were removed from the planters. Some small roots remained in the large planters and soil. The individual planters had their soil deposited into the red wheelbarrow. The large blue buckets kept the soil that was in them. We documented this process.
After finishing with the plants, the equipment was wiped down and stored. The floor swept and the tables wiped down.

0700: refilled 7 water bottle (3.5 L) watered other plants as needed 2 L
1830: refilled 1 water bottle (500 mL) watered other plants as needed 2 L
Changes to crops:
Several of the tomatoes that had shown stress on Sol 0 have shed a few of the leaves that showed stress at the time. Their appearance had remained similar (chlorosis with purple veins and necrotic spots) for the past several days prior to abscision. New growth on all plants looks to be green and in good health.
Cucumbers are closer to being ready to harvest. There are 3 cucumbers and more flowers that may become cucumbers.
Narrative:
In the morning the GreenHab was checked and watered as required. Initial temperature was 71.4 degrees Fahrenheit at at 41 % humidity. Humidity remained above 10 % throughout the day. The cooler temperature and increased humidity seems to have cheered up the plants. While the greenhab made it up to 105 degrees, it did not stay there long due to the afternoon storm.
The watering experiment is going well.
The experimental cooling setup which uses a cloth with water seems to be helping a little with the temperature and humidity, espcially at night when the building can be closed, however we will know more in the next couple of days. The surface area for evaporation and amount of available water is limited but, with more matierials, we could potentially try and keep the temperature under 100 degrees Fahrenheit and increase humidity so that stomata can open to allow photosynthesis. The prototype passively evaporated 1 liter of water and was not refilled until evening. Tomorrow checks will be done earlier in the day to verify water level over time.
Harvest: (include which crop and mass in grams):
Lettuce 34
Rocket(Arugula) 1
Micro greens 8

Narrative:
In the morning the GreenHab was checked and watered as required. Initial temperature was 90.8 degrees Fahrenheit dropping to only 86.9 degrees after the door was propped open. Air was stagnant. As per instructions the fan was not turned on.
Mission control was sent a request to permit working on ideas to cool the GreenHab with the goal of extending the greenhouse operations into the summer weather. This was granted and we began working to improve the airflow. We were able to generate a passive cross breeze in the GreenHab. Supplemental airflow was utilized during the midday peak heat of 105 °F and turned off when the clouds came back.
Utilizing several measurements in the GreenHab and referencing a psychrometric chart, we started the calculations to see if an alternative form of evaporative cooling could be constructed. We did a few tests with materials available to see which would be best for creating an adhoc cooling system. Further work will be done on this tomorrow. The goal being to always keep the GreenHab under 100 degrees. The temperature varied from 86 to 105 degrees Fahrenheit. It is noted that it is hottest in the morning and noon time frame due to the additional shade provided by the hab in the late afternoon.
