Dosatron SYSD15RE05VF – Proportional doser for precise indoor cultivation

Dosatron SYSD15RE05VF – Precise proportional dosing for indoor cultivation

The Sistema Hobby Dosatron SYSD15RE05VF from DOSATRON is a hydraulic proportional injector designed for indoor growers who refuse approximation. Without electrical power, it doses your nutrients and amendments directly into the water line, ensuring homogeneous concentration at each watering. A precision tool to secure your veg and bloom phases.

Benefits for your cultivation

Automating fertilization with the Dosatron means eliminating manual dosing errors and securing every growth phase, from veg to flowering.

• Constant nutrient concentration — The proportional principle guarantees an identical nutrient/water ratio regardless of instantaneous flow rate, avoiding peaks or deficiencies linked to pressure variations.
• Zero electricity required — The injector operates solely through water pressure, eliminating any electrical risk in humid environments and reducing failure points.
• Quick integration on existing line — Compatible with most indoor growing setups, it connects directly to your irrigation circuit without major installation modifications.
• Flow rate suited to compact and semi-pro setups — With a maximum flow of 18.9 L/h, it covers both a grow tent and a several square meter room in soilless or hydroponic systems.

Technology and performance

The Dosatron SYSD15RE05VF is based on a principle of hydraulic proportional injection : the integrated water motor draws and injects nutrient concentrate in direct proportion to the volume of water flowing through the device. This electricity-free motor mechanism ensures high mechanical reliability and dosing precision reproducible at each watering cycle, independent of network pressure fluctuations.

Reliability and use

Designed by DOSATRON, worldwide reference in proportional injection for professional agriculture and specialized cultivation, the SYSD15RE05VF is manufactured with materials resistant to acidic and alkaline nutrient solutions. Its compact design and minimal maintenance make it durable equipment, suited for intensive use in indoor cultivation under artificial light.

How to use the Dosatron SYSD15RE05VF?

Key steps to integrate and fully exploit your Dosatron in your indoor setup :

• Installation on main line — Connect the Dosatron directly to your water line upstream of drippers or spray lines, respecting the flow direction indicated on the device body.
• Dilution rate adjustment — Adjust the dosing ratio according to your nutrient manufacturer's recommendations for each phase (veg or bloom), and verify EC at outlet with a conductivity meter.
• Use of suitable concentrate — Prepare your stock solution in a dedicated reservoir at high concentration ; the Dosatron will perform final dilution automatically at each water pass.
• Periodic verification — Regularly check EC and pH of outlet water to validate dosing consistency and detect any clogging or system drift.

Properly calibrated, the Dosatron SYSD15RE05VF frees you from manual watering while maintaining precise and reproducible nutrition at each cycle.

Joseph's advice : "I use the Dosatron systematically once the number of plants exceeds ten. What I appreciate is reproducibility: once the rate is set and EC verified, I no longer need to adjust it. My advice: do your first calibration with water alone and a conductivity meter at outlet to validate precision before injecting your nutrients."
