Based on a traditional 16th century design, this thumb pot provides a novel way to gently water delicate small plants. Ideal for watering seedlings in the green house. To fill simply submerge in water. Covering the top hole with your thumb as you hold the top, carry the pot anywhere and the water will not leak. But remove your thumb and a fine shower descends from dozens of tiny holes in the base. Replacing your thumb over the hole will stop the flow instantly.
