Self Watering Planter

thingiverse

This is a self-watering (also known as bottom irrigation) planter that can be easily scaled to fit your space and plant. A realistic minimum size would likely be around 50% of the full version, which works well on a window sill. This three-piece print is designed to print without supports on any 3D printer. If you have multiple colors available, it's a good idea to use a second color for the float to make it more visible. Once printed: 1. Insert short lengths of synthetic cord through the holes on top piece to wick up water from the bottom piece. I used synthetic clothes line. The lines should be long enough to rest on the bottom when stacked, and knot at the top of each hole. 2. Fill the top piece with your potting mix and plant. Stack it on the bottom piece and water the potting mix from the top piece until fully saturated. Then complete filling the bottom piece from its fill spout, leaving a few millimeters unfilled. 3. Place the float on top of the water in the fill spout. Once the float sinks to the bottom, it's time to pull the float out and rewater through the fill spout. Printed full size with 5 wicks, this planter will keep potting soil fully moist for about a week before refilling is necessary.
