24-Piece Drip Irrigation Kit, Automatic Plant Sprinklers Irrigation System for Indoor and Outdoor Gardens and Homes

Adjustable Valve: The flow rate can be controlled. The plant watering device with a regulating valve allows you to control the drip rate from 0 to 60 seconds per drip, and continuous dripping lasts from 1 to 15 days. Simply adjust the valve to meet your needs without complicated setup steps. Save time and water.

Simple and convenient: Installed without any tools, simply drill a few holes in the bottom of the bottle or cut off the neck of the bottle to allow air to circulate freely.

Accurate water volume: Provides different amounts of water for different plants and flowers. It won't kill your plants. Other watering devices provide too little or too much water for some plants; old leaves simply turn yellow and fall off. However, if new growth is yellow, it may indicate overwatering or underwatering.

Warning: Compatible with all 1.1-inch/2.8 cm inner diameters, suitable for most beverage bottles, but not suitable for mineral or purified water bottles. (Measure the inner diameter of the bottle, including the thread size, before installation.)
