Kobra is a leader in water treatment technology and innovation with over 28 years of experience manufacturing in Brazil. The Dosatak GrowPro™ brings their proven volumetric dosing technology into cannabis cultivation. Powered entirely by water pressure with zero electricity required, the Dosatak automatically suctions, dilutes, and injects nutrients into the irrigation line with precise proportional dosing regardless of flow or pressure variations. Paired with Rivulis precision irrigation, the Dosatak and Rivulis drip system form a complete seed-to-harvest fertigation solution — Rivulis delivers water and nutrients to every emitter with uniform precision, while the Dosatak ensures every drop is dosed with the exact concentration your plants need.
Controlled dosing minimizes contamination risk and incorrect mixtures. Isolated internal injection means chemicals never contact internal mechanisms, enabling consistent cleaning and sanitization with reduced biofilm.
Automated dosing eliminates manual intervention and human error in nutrient mixing. Frees staff to focus on higher-value tasks while ensuring repeatable, batch-to-batch consistency across every feed cycle.
High-performance materials withstand harsh conditions including hard water. Durable diaphragm system requires less maintenance and fewer replacements, extending service life even under continuous commercial use.
Installs directly in the water line between the storage tank and irrigation system. No electrical wiring, no complex setup. Completely safe in humid environments with zero risk of electrical failure or burnout.
