MEDIUM-SIZED SELF-WATERING MINI PLANT Have you ever forgotten to water? We know... and we have the solution! This size is perfect for medium and large minis in their first pots: alocasias, philodendron, ctenanthe, etc. We have designed this self-watering system especially for minis. It is perfect for indoor plants in 9cm and 11cm pots, although you can use them in any size. They are handmade by our trusted potter, made of microporous clay to release the water your mini needs for days. The water passes through the pores, providing the constant watering your minis need, moistening the soil so the plant can absorb the water.
