Modern Sprout Watering Bulbs

Terracotta is naturally porous, which allows water to slowly seep through the walls of the bulb directly into the soil. Because the material is glazed, the evaporation rate is controlled, ensuring a steady, consistent release of moisture to the roots rather than a quick dump of water.

Yes, these bulbs are designed for both environments. However, keep in mind that outdoor conditions like high heat or direct sunlight may cause the water to deplete faster than the standard seven-day duration.

Simply remove the cork stopper from the top opening and fill the bulb with water. Once filled, replace the cork securely to create a seal, which helps regulate the flow and prevents water from spilling out too quickly.

These are best suited for small to medium-sized plants that prefer consistently moist soil. They are not recommended for succulents, cacti, or other plants that require a 'dry-out' period between waterings, as the bulb will continue to release moisture regardless of the soil's current saturation.

No, the flow rate is not adjustable. The release of water is determined by the natural porosity of the terracotta and the moisture level of the surrounding soil, making it a passive, self-regulating system.

Since there is no water level indicator, you will need to visually check the bulb periodically. Because the terracotta is opaque, the easiest method is to lift the bulb slightly or check the weight to gauge how much water remains.
