Future GreenHab Improvement Observations: spent some time in the GreenHab using the space to dry clay, there was a nice bench to put it on, in the sun so I’m quite happy about the space. Maybe what would be helpful is more flat buckets so the clay would dry quicker.

Daily water usage for crops: 6 liters

Daily water usage for research and/or other purposes: 20 liters for the clay from yesterday night and today. The clay had to be rehydrated and filtered. Then to separate the clay from the silt, water is added to a bucket. You stir for 30/60 seconds and pour the water in another bucket. The clay particles will stay floating and the silt will rest at the bottom.
