Dosatron D3GL-2 Green Line In Line Fertiliser Irrigation Injector

The Dosatron D3GL-2 Green Line In-Line Fertiliser Injector is purpose-built for garden centres and compact greenhouses, delivering precise fertigation directly in your irrigation line. Designed for versatility, it can be installed as a fixed unit or mounted on a mobile cart to roam your facility with ease. Ideal for propagation areas, it accommodates spot fertilization using a manual hose or an indoor spray boom, making nutrient delivery both targeted and efficient.

What makes the D3GL-2 unique

• Precise, adjustable dosing from 0.2% to 2% (1:500 to 1:50), letting you scale nutrient delivery to plant stage and crop type.
• Wide flow compatibility with water flow from 10 l/h to 3 m3/h and operating pressure from 0.3 to 6 bar, so it fits a variety of irrigation setups without fuss.
• Flexible injection rates for concentrated additives ranging from 0.02 l/h to 60 l/h, ensuring you can tailor treatments from gentle feedings to robust applications.
• Ergonomic, future-ready design that evolves with farming practices and treatments, offering an adjustable, user-friendly experience in real-world greenhouse workflows.
• Mobility and placement options — install inline for a permanent solution or mount on a mobile cart to reposition across growing areas as needs change.
• Multi-use capability supports growth control, phyto-sanitary plant treatments, and integrated pest management, keeping plants healthy across stages of growth.
• Reliable connections with standard NPT-BSP Ø 20x27, 3/4" M fittings and PVC hose Ø 8x12 with a length of 1.75 m, ensuring straightforward integration into existing systems.

Ideal use scenarios

• Spot fertilization in propagation benches or plug trays where precise nutrient delivery matters for uniform root development.
• Inline fertigation for compact greenhouse aisles, allowing consistent dosing without manual measuring at every watering cycle.
• Indoor spray-boom setups for uniform coverage during growth phases, disease prevention, and pest management applications.
• Mobile cart deployments in small facilities where different zones require targeted feeding and treatment at different times.

How it works and practical benefits

In-line fertiliser injection blends concentrated additives into your irrigation flow based on your chosen ratio, delivering consistent nutrient delivery directly to the root zone. This eliminates guesswork, reduces waste, and ensures crops receive the right amount of fertilizer precisely when they need it. With the D3GL-2, you gain dependable operation across varied water pressures and flow rates, so you can run fertigation during peak production windows with confidence.
