Self-Watering Octopus Wide Mouth Mason Jar Planter

Share this:

Similar to our other mason jar planters, this planter is self-watering. Set up once and revisit pretty rarely. It has tiny holes in the tentacles that would let water in from the mason jar reservoir and let the capillary action work to keep the soil moist, as long as the bottom-most tentacle is under water and soil reaches down there in the inside. It includes a water channel on the side so that refilling the reservoir conveniently doesn’t require opening the whole assembly.

This works with 16oz mason jars with wide-mouth.

This model requires support. Use 3 walls with 0.4 mm nozzle. Print slow on the outside to let the details printed nicely.

For instruction or care, see this How-To section for our self-watering mason jar planters.

This planter is used in this Pon project.
