Blumat Classic Plant Watering Stakes - Self-Watering Insert for Indoor and Outdoor Plants - Automatic Slow Release Irrigation System for Potted Plants - Houseplant Care Device (5 Pack)

The original Blumat for houseplants - made in Austria, not the poor quality Chinese-made versions.Take a vacation and let your plants look after themselves. Blumat Plant Savers ensure a constant supply of water. They automatically supply just the right amount - never too much or not enough. Your plants will love it. They won't experience the drying out that stunts growth or the over-watering that squeezes the air out of the soil and keeps them from 'breathing' properly.As the soil dries, the ceramic cone delivers water gradually into the surrounding earth - thereby creating a vacuum within the cone which draws water from the nearby container of water. Once the soil is moistened the Blumat Junior will cease flowing water. It waters your plants only as needed. You can even add fertilizer to the water supply. This slow, continual feeding encourages prolific growth.Blumat Juniors will only draw water up 12 inches (30cm). If the surface of the water in your container is lower than this, the flow of water will be restricted and the plants gradually dry out. Each Blumat Jr. has a limit on how fast it can deliver water. Several cones may be necessary for larger plants in order to meet the higher water needs. In this case, a larger reservoir of water must also be available.
