What it does

Transforms any standard jar into a self-watering planter
See-through water level indicator, never over or underwater again
Perfect for growing herbs like basil, salad greens, and small plants
Eco-friendly design uses less plastic by repurposing jars you have

The Jargar is a clever 3D printed home decor piece that turns any leftover jar into a self-watering planter. The transparent jar body lets you monitor water levels at a glance, taking the guesswork out of plant care.

The self-watering mechanism keeps soil consistently moist, making it ideal for growing basil, lettuce, and other herbs indoors. By reusing jars you already have, you'll use significantly less plastic while creating a modern, minimalist planter for your kitchen or windowsill.

The design fits standard 67mm jars common in Eastern Europe, though you may need to adjust dimensions for jars in your region. Whether you're into urban gardening or just want fresh herbs at your fingertips, this printable planter blends sustainability with smart design.
