For the crops 05:00 to 11:59 PM

Changes to crops: There have been two cloudy days in a row, so the crops did not require much water. Used all of the remaining tomato cages to support the larger tomato plants. Seeded several crops. Used the old seed to see what will grow. If there is no germination, newer seed packs will be used.

Below is an updated inventory of all of the crops, quantity, growth stage, actions taken, and notes.

Daily water usage for crops: 5 gallons

Time(s) of watering for crops: 05:30PM

Research observations: Sprayed moringa experiment with moringa extract as directed. Microgreen sprouts are growing well.

Changes to research plants: None.

Aquaponics: Not in use.

Narrative: The larger tomato plants were starting to lean over, so I used all of the cages available to support as many plants as possible. The rest of the tomatoes will need cages soon, as will the vining cucumbers. The cucumber plants have already started climbing the shade cloth and lighting cables in their quest to take over.

To maximize the efficiency of the Green Hab, it is important to select crops that are suited to greenhouse production and to space out plantings of crops to ensure steady yields. For future Green Hab officers, I would recommend against planting things like melons that can require up to 75 sq ft per plant and have a 10 ft long tap root that is not easily accommodated in a pot. The 50+ tomato plants seem to have been planted at the same time, which means that they will start yielding at the same time. Hopefully the crew on rotation can freeze some tomato sauce for future crews to use.

To bring more crop variety to the Green Hab, I planted carrots, onions, broccoli, scallion, three varieties of lettuce, Swiss chard, arugula, quinoa, and mustard. These were the seeds available, but many are also fast growing crops that have high yields in a greenhouse environment. I used the oldest seed packets, and will replant with newer seed if nothing grows. If future officers continue plantings every two weeks, then there should be a bountiful and regular harvest for every crew.

Support/supplies needed: 50 more tomato cages will be needed to support all of the tomatoes and cucumbers currently growing in the greenhouse. All of the cages we have are in use.
