Narrative: Temperatures were high again today but the GreenHab stayed fairly cool. The fan was running on the highest setting from 11:00 until around 19:00. Crops are looking healthy but I think it’s been too hot for the flowering tomato plant. The fertilizer and lower temperatures from yesterday seemed to help but it’s still showing signs of stress. Harvested parsley and sage that was used in the crew’s lunch and dinner.

Harvest: 21 g parsley, 1 g sage

Narrative: Crops are looking good but the tomatoes are starting to show signs of nutrient deficiency. I’ll fertilize them with Miracle Grow tomorrow and see if it improves. It’s been hot, but the fan is running on it’s highest setting throughout the hottest parts of the day. The GreenHab door shut at some point before 6:45 due to high winds.

Changes to Crops: None.

Narrative: Our crew spent the day at Salt Creek, a few miles away from the station. Before we left, we watered the crops and left the GreenHab door open but the interior temperature still reached 43 C while we were gone. Since outdoor temperatures are likely to increase until the fall, we’ll probably have to run the fan in addition to propping the door open from here on out. I’ll program the fan to operate during the hottest parts of the day and report the schedule tomorrow. There are discrepancies among the thermometers in the GreenHab and a couple of them have problems with their digital displays. They should be replaced.

Narrative: Crew 210 arrived on site this afternoon. The crops look alright for the most part, save for some wilting and stunted growth. The tomato seeds were sprouted in large pots with loose soil, which may explain their inability to continue growth past sprouting cotyledons. Energy stores within the seed will support initial growth, but with large-particle-sized substrate and large pots, the short roots have trouble reaching anything of value, even when the substrate still looks properly watered.

The herb beds and crops that are further along in their growth cycles look healthy. Temperatures are very comfortable here but that means it’ll likely be too hot in the GreenHab during the day. I’ll make sure to leave the door propped open and water the crops before our crew heads out to Salt Creek.
