Narrative:
Sol 5:
Today was an interesting day lolz, especially with the EVA! I went into the greenhab a little earlier to quickly water the plants to get them ready for the higher temperatures later in the day. Eshaana tended to her cute little solar farm by adding cling wrap to the pot to retain moisture! Since she is growing kale and C4 grass, the soil moisture is a big deal! I then went to the Science Dome to take some water over for my hydroponics setup (2 Liters in each module). I already see some kale seeds cracking into baby leaves!! I did test the pH and water temps of the hydroponics modules as well (reported in my research paper).
After our LiDAR scanning EVA, I came back to the greenhab to add some cling wrap on the carrot plants. I noticed that the carrots are the only plants that are quickly losing water. Condensation should definitely help! I actually started sweating in the greenhouse which was new lolz! There is also some new baby lettuce leaves! Adriana made some potato gratin and a yummy sour cream/dill sauce to go with it! She also made some amazing enchiladasfor dinner and she used the cilantro that was harvested! Today was super fun!!
Sol 4 Harvest:
Dill: 4 grams
Cilantro: 8 grams

Narrative:
Sol 3:
I started off today as usual by heading to the GreenHab while on the way to do my work in the Science Dome. We made relatively easy dishes today, so I did not harvest anything. We made parmesan broccoli with the pizzas so I used the leftover dehydrated broccoli (powdery) to put in the soil along with more orange peels and coffee grounds. I have been keeping up with the humidity by using the mister spray bottle. I will continue to mist occasionally throughout the day, depending on EVAs too. I also took pH level readings of most of the plants just to check if everything is healthy!
      Soil pH Levels:
      Static Water Tank (8.45)
      Carrots (7.71)
      Cucumbers (7.5)
      Tomatoes (6.63)
      For Eshaana’s plants, we are thinking of using plastic food wrap to help with the condensation. This can help with water conservation too! I can try to use this for the tomato plants as well. I also noticed that the kale, lettuce, and arugula that I harvested a few days ago, are now growing more baby plants! The radish also doesn’t seem too sad and the stems seem to be stronger. With the carrots, I will have to keep checking on it since the leaves look depressed lolz…

Changes to Crops: Adriana helped me find a spray to keep the humidity levels high enough. I watered earlier in the day to work with the heat in the afternoon. I made sure to keep the carrot plants moist.
Narrative:
Sol 3:
This morning temperature was quite crispywhen I went over to the greenhouse. I was mainly concerned about the clay pots filled with water that I put all over the greenhouse, but the heater allowed all of it to evaporate! So that is great! The humidity percentage was 52% yesterday. The only thing I was confused about was why some of moisture did not retain. Adriana did find a spray bottle so that I can mist the greenhouse! The humidity was constant at 27% for a few minutes. Adriana and Eshaana helped me find some gaps that are along the structural beams of the greenhouse. These gaps might be causing the water to dry away throughout the day. Hoping we can fix that! I also harvested about 7 grams of basil and they looked so cute!!! I am also starting some pH tests to check the soil content so I will note that today.
Eshaana also has her awesome mini solar farm in the greenhab to test kale and C4 bermuda grass growth under no shade, partial shade, and full shade solar conditions! She will be tracking the time period of growth based on each test case of the solar shade. She is alo taking temperature, IV tracer, and solar irradiation! Can’t wait to see the results!!
Sol 3 Harvest:
Basil: 7 grams
Support/supplies needed: Do you know how long the heater stays in the greenhouse? Also, I noticed that the greenhouse structure has several gaps and maybe this is why the moisture does not retain. Is there any way we can repair the outside of the greenhouse to seal all holes/gaps with something?

Times of Watering for Crops: Sol 2 – 3:08pm
Changes to Crops: Tied metal wires to the stakes of the cucumber plants so that they don’t keep falling and droop over. I made the knot snug (not to tight)! I made a composting pot with the orange peels and dead leaves.
Narrative:
Sol 2: Today’s weather was a little better than yesterday. The main thing that concerns me is the dry atmosphere there. I will start doing pH level tests for the larger plants and carrots. After replanting the carrot plants yesterday, they look a little sad, but I’m guessing the low humidity level is playing a big part into it. I have been saving the produce scraps from out food (like oranges) to use as compost for the soil. We can get more natural fertilizer, less waste, and provide raw nutrients for the soil like this. After creating the compost mixture, I moistened it and left it on the rack. I also used an extra 3 liters of water to place it in clay pans all over the greenhouse. Hopefully with this, the water can slowly evaporate with the heater on and increase humidity levels. I went through the cabinets and tried to search for a spray bottle. Couldn’t find one in the science dome either. I found a pesticide spray that could work instead but there is no rod for it. I want to use the spray to mist the water in the greenhouse and moisten the air before the afternoon heat hits here.
For harvesting, there were a lot of leaves overcrowding. I took large bunches of the kale, lettuce, and arugula. The crew used these to make a mango/almond salad along with the Thai Curry and rice we had for dinner.
Sol 2 Harvest:
Kale: 56 grams
Arugula: 30 grams
Lettuce: 22 grams
Support/supplies needed: Do you know if the large, black rod for the pesticide spray is somewhere? Not spray pesticide, just water.

Changes to crops: Fixed cucumber plants, replanted the brocolli/radish plants in bigger pots. Also harvested lettuce, basil, arugula, cilantro, and parsley!
Narrative:
Sol 0: Went in the greenhouse at about 3pm and watered all plants using a total of 1 gallon and 4 liters. I was able to aerate the soils of the tomato plants. The greenhouse was VERY warm with a temperature at 93 degrees Fahrenheit and there was only 10% humidity! Optimal humidity should be close to 40%-60% for temperate plants that are growing vegetables. After watering, I turned on the fan for 15 minutes to reduce the temperature to 80 degrees Fahrenheit. I was able to put sticks in the cucumber plants to help them stand up and grow better with the space. The humidity level also increased to 13%. For today, the only plants we harvested was the basil and lettuce. We used the basil for the quick Jambalaya we made for lunch while the rest of the crew was out fixing the car rentals and we used lettuce (18 grams) for the black bean burgers at dinner. After dinner, I was able to go back into the greenhouse at 10pm and check on the rest of the plants once again. The temperature was 71 degrees Fahrenheit with 10% humidity.
Sol 1: I went to the greenhouse today at 2:38pm and noted a temperature of 89 degrees Fahrenheit at 10% humidity. After watering with about 2.1 gallons of water, the humidity levels went up to 17%. I used up most of the time replanting the radish and broccoli plants. Especially for the broccoli and radish, the pots were becoming small for the roots, so I put them in a bigger pot to aerate the soil and make it comfy! At about 3:40pm, I harvested about 95 grams of kale for the pasta salad that we made for lunch! After lunch, I noticed that there was no spinach planted in the greenhouse, so I used the seeds I brought to set up a new pot! I put about 2-3 seeds in the 8 holes that I made. After that, I rearranged and properly fertilized the carrot plants with the MiracleGro Plant Food (1½ tablespoon) and a sprinkle of Jobes Organic Fast Start Fertilizer.

Time(s) of watering for crops: 6 pm
Changes to crops: Harvested some crops, all crops growing well.
Narrative: I used a lot less water today because I am letting the soil of the cucumbers and the tomatoes dry out before watering again (there is still a lot of moisture in the soil). I harvested enough plants today to make a medium salad and provide toppings for our burger night. The peas are growing exceptionally well (both pre-planted and the ones I just planted). Hopefully we’ll also see some tomatoes growing by the end of the week too. I am still watching two of the cucumbers, which seem to be doing slightly better today but are not growing all that well currently. I suspect I might have given them too much fertilizer and that they are still recovering from that (fertilizer burns).
