Blumat Classic is a passive, self-watering spike for houseplants. The porous ceramic cone releases water directly into the soil while a capillary tube draws from any nearby container; raise or lower the reservoir to tune flow. Depending on reservoir height, the Classic dispenses about 50 ml/24 h (container significantly lower), ~75 ml/24 h at the ideal level, and up to 150 ml/24 h if the water level is above the green cap. Classics will only lift water up to about 30 cm (12 in) from the water surface. Use multiple units for thirstier plants or larger pots. The single-unit pack contains 1 x Blumat Classic. Components in contact with water meet Austrian drinking-water standards and are free of BPA, PFAS, and phthalates.
