I want to set up a windowsill garden again, but the reason I lost intrest last time was the watering process. I had to take very pot from the windowsill to the sink, water it, let it drain, and bring it back to the widowsill again. It's not a really efficient way of caring for a larger collection.
Is their any way I could water the plants while keeping them on the windowsill? I thought of having the pots on a tray of gravel, but that would only work for humidity lovers, not desert plants. Any additional ideas?
