Remember to monitor plant and seed bottles daily for over zealous watering… Over the weekend the plant bottle ran a muck because someone had added too much water. This is not a failure, but just a setback that turns into a teachable moment. Bad weather and flooding can destroy crops. Watch the bottom of the plant bottle. Any collecting water should not touch the soil above the rocks. Preschoolers can use a water dropper to add water. One a day should keep the bottle from gaining too much water.
Another note: Potatoes can stink! We started over again with a new plant bottle, a new celery bottom, and washed the potato so all of the rotting flesh was gone. In one corner chia seeds were added just because we had some in our supplies. Everyone is ready to start writing again about the plant bottle in the journals.
