High-quality plastic construction provides aging resistance, a shiny rust-proof finish, and long service life. Practical and adjustable: this emitter offers two flow modes, water mist and water column. The flow can be adjusted as needed and the device can be flexibly positioned to match the plant location with the dropper. Easy to use: simple installation. It can be used alone or with a dripper to stabilise the flow rate of the dropper. Robust and reliable: designed for strong toughness with good tensile and bending strength, and resistant to ageing and corrosion for durable performance. Compatibility and performance: suitable for use with drip irrigation setups and standard drippers to control irrigation flow. Use scenarios: - Greenhouse or seedling tray: switch to mist to maintain humidity for delicate seedlings. - Potted houseplants: use the water column mode for steady, rooted-zone watering. - Terrarium or humidity-controlled enclosure: use mist mode to sustain consistent humidity levels.
