Change to crops: The icicle radish has a lot of bite marks on the leaves and small mites flying around it when the leaves are touched. I am assuming that there is an infestation of some bug, e.g. caterpillar, eating the plant. I sprayed the plant with organic pesticide to attempt to kill the bugs.


1st sprouts: N/A

Harvest: N/A

Other: Since the thermostat is set to 21 , the GreenHab has gotten substantially hotter. I needed to leave the door open many times so that the temperature would not exceed 30 . This increase in temperature is still negatively affecting the plants by the GreenHab door by making the leaves crispy and the soil dry out faster.

Suggestions: After a brief discussion with Outpost, I was wondering if it was possible to move the thermostat to a cooler 19 . The temperature would not be too cold for the plants, and it would not create too much heat resulting in the door needing to be opened constantly.
