From vertical racking and rolling benches to precision irrigation and centralized environmental controls — the structural backbone of every high-performance cultivation facility.
Global Micro-Irrigation Manufacturer • 110+ Countries
Rivulis is a global micro-irrigation manufacturer built around accessibility, partnership, and innovation. Operating in over 110 countries, they design, engineer, and manufacture every component in-house — delivering precision water and nutrient delivery engineered for efficiency, uniformity, and crop quality. Their Indoor Cultivation line is purpose-built for greenhouse, indoor, and soilless production — scalable irrigation solutions for high-performance growers cultivating high-value crops.
No-drain drippers with self-flushing mechanism for pulse irrigation capability. Uniform delivery across every emitter regardless of line length or elevation changes. Fertigation-friendly for precise nutrient delivery to high-value crops.
Complete drip irrigation systems for soil and substrate applications. Drip tape, drip lines, and online drippers sized for greenhouse, indoor, and soilless production environments at any scale.
Pressure-compensating micro sprinklers with adjustable spray patterns. Foggers and misters for climate-support environments, propagation, cloning, and nursery production applications.
Semi-automatic screen and disc filters with self-flushing mechanisms and clogging indicators. The first line of defense for system reliability — protecting emitters from debris and biofilm buildup.
UV-resistant PE tubing, Power-Loc push-fit fittings for tool-free assembly, irrigation control valves, pressure regulators, and complete headworks assemblies. Everything needed from source to emitter.
Full design and planning, hydraulic support, logistics, installation, training, and ongoing technical support. Monitoring and irrigation scheduling tools. Complete buildouts from concept to operational system.
Dosatak GrowPro™ — Precision Nutrient Dosing Powered by Water
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 — the most reliable dosing solution for the cannabis market. 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. Stable EC and pH throughout the entire cycle, cleaner systems, and uniform nutrition across every plant.
First volumetric and proportional liquid dosing device powered solely by water pressure. Three adjustable dosing ranges: 0.1–0.5%, 0.4–2%, and 1–5%. Flow range 0.02–13.2 US GPM. Operating pressure 3–80 PSI. ¾" external thread (BSP/NPT). Robust diaphragm system rated for hard water with internal isolated injection — chemicals never contact internal mechanisms.
Complete nutrient delivery panel with pre-filtration, cluster of multiple dosers (Silica, Grow, Bloom, pH Buffer), independent valves, integrated pressure gauge, return/safety line, and modular expansion support. Compatible with external EC/pH sensors for closed-loop monitoring.
50L and 200L polyethylene mixing tanks with stainless steel rod and propeller for homogeneous concentrate preparation. External graduation markings and audible level sensor alarm. 220V motor (1/3 CV, 60Hz). Designed for use with the Dosatak for reliable upstream blending.
Stainless steel impeller and volute for corrosion resistance. 1" BSP-NPT inlet/outlet, 1.3–9.2 GPM flow rate, max 50 PSI working pressure. 0.5 HP, 220V/60Hz. Automatic operation for uniform pressurization across extended irrigation lines and larger facilities.
Nebulizer nozzle filters (25 and 50 micra), medium/low pressure filters (60 micra), evaporative panel filters (1000 micra) for climate cooling. ACIKOBRA organic acid tablets, trichlorine tablets, BRADOX chlorine dioxide test strips, and silicone lubricant for system maintenance.
Premium European paper evaporative cooling pads for passive climate management in greenhouse environments. Reduces ambient temperature through evaporative cooling without mechanical refrigeration, lowering energy costs and maintaining optimal growing conditions.
Coming Soon
Commercial reverse osmosis water purification systems for indoor cultivation are coming to Hydro Supply Co. Clean, mineral-free water is the foundation of precise nutrient management — and we’re building out our RO lineup to give growers full control over their water quality from source to root zone. Quoting is currently available for customers planning their water infrastructure.
