• Adjustable Slow Release Valve: Our plant watering spikes feature an adjustable control valve that allows you to set dripping speed from 0–60s/drip.

• Premium Durable Plastic Material: These automatic plant waterers are made of high-strength sturdy plastic with high toughness, heat resistance and cold resistance. Safe, reusable and long-lasting, they are suitable for long-term indoor and outdoor use without easy breakage or aging.
• Universal Bottle Compatibility & Notes: These watering inserts fit most beverage bottles with an inner diameter of 1.1 inch / 2.8 cm. NOT suitable for standard mineral water or purified water bottles due to thread and size differences. Please measure the inner diameter including thread before installation. For better water flow, drill small holes at the bottom of the bottle or cut the tail slightly to maintain air pressure balance.
• Wide Application for Indoor & Outdoor Plants: Perfect for potted plants, houseplants, patio plants, herbs, hanging baskets, desk pots, small trees, shrubs and outdoor gardens. Easy to install without tools, just screw on the bottle, insert into soil and adjust the valve. Keep your plants hydrated while on vacation, business trips or busy daily life.
• Notice: This automatic watering spike is only suitable for small bottles of around 500ML. It is not compatible with large bottles over 1L. Extra-large containers are heavy and unstable, making them easy to tip over and cause water leakage.
