Self Watering Spikes, Plant Devices, Slow for Plants, 20 Pack Adjustable Drip Irrigation Spikes with Valve Control Indoor Outdoor Potted Plants

Adjustable Valve Control: Each plant watering device features a valve that lets you set the dripping speed from 0 to 60 seconds per drip, providing slow watering for plants that lasts 1 to 15 days. Simply adjust the valve to match your plants' needs — perfect for travelers who want to keep their plants hydrated. Upgraded Consistent Pressure Design: These self watering spikes adopt a constant-pressure structure for a more stable water flow. The dust-proof connection mouth helps prevent dust and insects from entering, reducing the risk of clogs. Easy to Use: No tools required — just attach a plastic or glass drink bottle, insert the watering stake into the soil, and open the control valve. Adjust the flow rate as needed, and the system takes care of the rest. Fits Most Bottles: Designed with an inclined reverse plug-in interface, our self watering spikes are compatible with beverage bottles with a 25–30 mm caliber. The design isn't affected by water pressure and won't stop dripping unexpectedly, so there's no need to poke holes in the bottle. Wide Application: Use these plant watering devices for indoor or outdoor plants, at home or in the office. They work well with potted plants, houseplants, patio plants, hanging baskets, and more.
