Nutrient Dosing Systems for Precision Feeding and Water Management
Consistency is everything in cultivation. The right nutrient dosing system doesn’t just save time — it transforms precision into performance. At Key to Life Supply, we provide commercial-grade nutrient dosing and delivery solutions that ensure every drop of water and nutrient is measured, mixed, and distributed with total accuracy.
From Hi-Flo Etatron Ultrasonic Micro-Dosers to Dosatron Water-Powered Injectors, our lineup is engineered for growers who demand control — whether you’re managing a large-scale hydroponic facility or fine-tuning small batch fertigation. Each system balances reliability, scalability, and simplicity, so you can automate dosing, stabilize feed ratios, and optimize plant health across every zone of your grow.

Why Precision Dosing Matters
When nutrients are mixed manually, the smallest inconsistencies can create huge variations in plant performance. Automated nutrient dosing eliminates that risk — delivering exact feed ratios and pH balance every time, regardless of system size or operator.
Our dosing systems:
- Eliminate mixing errors and nutrient waste
- Maintain consistent EC and pH across all zones
- Reduce maintenance time and manual labor
- Improve root zone health through precise nutrient delivery
- Integrate easily with existing irrigation infrastructure
By ensuring perfect proportional mixing, these systems help growers unlock maximum yield, efficiency, and sustainability — without overusing inputs or compromising quality.

Hi-Flo Etatron Ultrasonic Micro-Doser Series
Designed for professional and commercial-scale operations, the Hi-Flo Etatron Micro-Doser Kits bring lab-grade precision to the greenhouse. Each unit features ultrasonic injection technology for quiet, efficient, and accurate delivery — even at high flow rates.
These modular systems are built for high-flow commercial irrigation, supporting flexible expansion, and minimal maintenance. Perfect for operations that require continuous, balanced fertigation over long cycles.
Available Configurations:
Lo-Flo Etatron Micro-Doser Systems (3/4”)
For smaller or more specialized applications, the Lo-Flo Etatron line provides the same intelligent control and proportional dosing at lower flow rates — ideal for boutique growers or propagation setups.
With their smaller form factor, these systems maintain professional-grade performance while conserving space and energy — a perfect solution for growers scaling up efficiently.
Popular Models:
Water-Powered Nutrient Delivery Systems
When electricity isn’t an option, water-powered nutrient injectors offer the perfect off-grid or low-energy dosing solution. Designed for reliability, these systems harness the pressure of flowing water to proportionally mix nutrients into irrigation lines — a tried-and-true method trusted by growers worldwide.
Each system is easy to calibrate, self-powered, and engineered to handle a wide range of fertilizer viscosities — making them ideal for hydroponic, aeroponic, and soil-fed environments alike.
Key Systems Include:
Dosatron Water-Powered Injectors
A global leader in proportional dosing, Dosatron injectors are the gold standard for precision fertigation. Using hydraulic power (no electricity required), they inject nutrients directly into your water line based on exact flow ratios — ensuring every plant receives the same consistent mix.
Why growers trust Dosatron:
Proportional injection regardless of flow or pressure changes
Simple maintenance and easy calibration
Durable polymer housings resistant to corrosive fertilizers
Compatible with acids, nutrients, and organic blends
Optimize Your System with Flow Restrictors and Accessories
To maintain system balance and protect your dosing equipment, Key to Life Supply also offers a full range of flow restrictors, hammer arrestors, and filtration kits. These ensure smooth operation, consistent pressure, and reduced wear on key components.
Each accessory is designed to integrate seamlessly with Etatron, Dosatron, or Mega-Flo setups — ensuring your dosing system runs with precision from end to end.
Integrate with the Key to Life Ecosystem
Your water is only as effective as the nutrients it carries. Pairing nutrient dosing systems with Key to Life’s organic nutrient line — including Silver Bullet, Green9, and Cal(No)Mag — creates a complete, biologically balanced irrigation environment.
By combining precision dosing with clean, active water and organic nutrients, you’re empowering your system to deliver maximum plant vitality while maintaining long-term system health.
