This adjustable drip irrigation system makes it easy to water your plants, and it works with most standard plastic bottles (such as soda or mineral water bottles ranging from 0.33L to 2L). It provides a steady and controllable flow of water for both indoor and outdoor potted plants as well as greenhouse plants, making it perfect for use on trips or for regular maintenance.

The built-in valve allows you to fine-tune the drip rate. To ensure proper operation, don’t tighten the cap too much—leaving a small gap lets air in and maintains water pressure. If needed, you can also poke a small hole in the bottom of the bottle with a needle to improve airflow. But in most cases, just securing the bottle loosely is enough.

Easy to use and low maintenance, perfect for any plant lover!
