Suyeah Self Watering Spikes (24PCS)

Ensure your plants stay hydrated with these automatic self-watering spikes, perfect for indoor or outdoor use. Crafted from durable, high-quality plastic, each dripper features an adjustable valve allowing you to control the drip speed from 0 to 60 seconds per drip. A 550ml bottle can sustain plants for 5-7 days, while a 2-liter beverage bottle can last 7-20 days. The screw-top design ensures easy connection to most standard beverage bottles (1.1-inch inner diameter, excluding mineral or purified water bottles). For optimal use, dig holes in the bottom of the water bottle or cut it to prevent issues caused by atmospheric pressure. Ideal for potted plants in gardens, homes, or offices, these spikes provide a worry-free solution for plant care, especially during holidays.
