Changes to crops: Thinned/pruned cucumbers and tomatoes

Narrative: Everything is looking less wilted this morning and it is 83 F which the plants seem happiest at. By 4:15 the cucumbers and half arugula were wilted. Today I pruned and thinned the tomatoes, and pruned dead leaves from the cucumbers. I observed some stunted cucumbers (1 cm) but they were withered. I removed flowers on some lower stems to encourage stronger fruiting. I prepped pots with soil to begin my experiments. Around 5:00 PM we lost power and exited the sim. We attempted to find solutions to plug the GreenHab heater into the portable generator, but could not. By ~9:00 PM the temperature in the GreenHab was ~45 F, but this was with no less than 10 times entries and exits from the GreenHab which undoubtedly caused loss in heat. The space heater from the RAM was set up in the GreenHab and the plants survived the night well. More details to come in the next report.
