Long time since the last update. The seedlings are all growing well. In the meantime I am preparing the autopots and the greenhouse.
I will fill the bottom of the autopots with a layer of 3 cm clay pebbles to help the flow and give air to the roots.
I have read it is important to rinse the pebbles in water in 48 hours to ensure they are PH-stable.
I have also taken one of my tomato plants from the grow closet into the greenhouse to see how it will thrive.
