Some of my plants are prone to root rot and require allowing the soil to dry between watering. I have a bunch of these to allow me to fill each up and walk away. The water is introduced slowly enough to wick back into the dry soil without running off carrying soil with it. Is also useful for metering liquid fertilizer since you know exactly how much you added and are sure all of it is soaked into the soil
There are two files: a half and a full. Use the full if you can fit it on an existing plant. The half is for adding to an existing plant. Print two and snap together.
