Product Details Irrigation Spike - Dimensions H x W x D: approx. 18 x 5.4 x 5.4 cm - Inner diameter: approx. 4.3 cm - Material: ceramic - Color: terracotta 1. Made of Terracotta – Slow Release Water Automatically: The plant watering device is made from terracotta clay, which is naturally porous and may be fragile due to its material properties. The terracotta watering spikes release water gradually into the soil. The thinner the spike wall, the faster the water release. Due to the nature of ceramic, some spikes may arrive broken. We take full responsibility for any damage during shipping. 2. Easy to Use with Long Neck Wine or Plastic Bottles: First, dig a hole in the soil. Gently insert the watering stake into the soil. Fill a bottle with water, attach it to the stake, and turn it upside down. Insert approximately 7/8 of the stake into the soil for optimal performance. Using multiple stakes allows for greater water absorption. Note: For heavier bottles, insert nearly the entire stake into the soil to prevent breakage. 3. Pack of 6 Plant Watering Stakes: This set includes six ceramic watering stakes. Each stake measures 6.3 inches in length and weighs 3.52 oz. Compatible with used wine bottles or long-neck plastic bottles, these stakes offer an eco-friendly way to repurpose containers while simplifying plant care. 4. Slow Release Watering for Vacation Use: There is no fixed release time, as water dispersion depends on pot size, soil type, plant needs, and environmental conditions. On average, 1 liter of water lasts approximately 7–10 days. Designed to prevent overwatering, these stakes help maintain consistent moisture levels when you are away. Test the system before leaving to ensure proper function. 5. Ideal for Frequent Travelers: These self-watering stakes provide reliable moisture delivery, allowing you to travel without worry. Ensure your plants stay hydrated with this simple, effective solution.
