Pack of three terracotta self-watering funnels

The large self-watering funnel is made of terracotta, which is a porous material that continuously hydrates the substrate of your seedlings. The self-watering funnel works by fitting a wine bottle filled with water into the wide side of the funnel. Insert the small part of the funnel into the potting medium, taking into account the distance to the roots.

The self-watering funnel is 17 cm long.
