Upcycle Jar Greenhouse

With this versatile model, you can breathe new life into discarded glass jars commonly found in Europe by transforming them into mini greenhouses for your plants. The ingenious design boasts a water reservoir and a lip that cleverly collects condensation water, which is then expertly re-injected back into the reservoir (Refer to the cross-section image for detailed specifications). Thanks to its unique hexagonal shape, you can effortlessly pack these mini greenhouses in a honeycomb pattern or mix sizes with ease. I have created four distinct models tailored to match four different sizes, but feel free to design new sizes that perfectly fit your jar. To find your ideal size, simply measure the outer diameter of the opening on the jar. The 72mm model is also available with larger sides, specifically designed for apple purée jars that have narrow openings but are quite wide. This thoughtful design allows you to pack them together without the glass touching. **Essential Watering Tips:** When placing the glass jar directly on it, refrain from using the reservoir or keep the water level in it extremely low (0.5 cm). The greenhouse will be sealed, preventing the water from evaporating and resulting in excessively wet soil. Use the reservoir only when not utilizing the glass. Happy gardening!
