Upcycle Jar Greenhouse

With this model, you can upcycle the glass jars commonly found in Europe into mini greenhouses for your plants. It has a water reservoir and a lip to collect condensation water and re-inject it in the reservoir (See cross-section image for detail). With the hexagonal design, you can pack them in a honeycomb pattern or mix sizes easily.

I have created 4 models matching 4 different sizes but you can easily design new sizes for your jar.

To find your size, measure the outer diameter of the opening of the jar.

The 72mm is also available with larger sides because my apple purée jars have narrow opening but are quite wide, this is to allow to pack them together without the glass touching.

**Watering tips:**
If you keep the glass jar on it, don't use the reservoir or keep the water level in it very low (0,5 cm), because the greenhouse will be closed, the water that you put will not evaporate and the soil will be too wet. Use the reservoir only when not using the glass.
