Thunderstorms rolled through and dropped the temperature significantly. Moved the pot into the plastic balcony greenhouse to keep it dry. Humidity dome is off and only a couple of sprays of water every second day.
Was concerned I had overwatered initially as the seedling sprouted with only the cotyledons showing but by Day 3 the first set of fan leaves began to appear.
Had a couple hours of light rain on day 6, then about 50ml of water around the edges to try to encourage the roots on day 7.
Still a very small plant. Better weather due next week.
