BDX BatchMATIC™ Fertigation System
Pre-assembled batch fertigation system: mixes nutrient batches for up to 14 irrigation zones or holding tanks with 5 to 12 dosing pumps, redundant sensors and a touch screen.
Batch Fertigation, Simple to Run
The BDX BatchMATIC™ mixes nutrient batches and delivers them to plants, hydroponic systems or holding tanks in a simple fill, mix, feed sequence that is easy to program and run.
Designed for multi-room indoor facilities and mid-sized greenhouses without being overpriced or over-complicated, and built on over a decade of proven Agrowtek technology.
Fill, Mix and Feed
The base system has six zone valves, expandable to fourteen irrigation zones or batch tanks per machine. Choose 5, 6, 10 or 12 chemical pumps for EC nutrient dosing, pH up, pH down and ORP as required.
Precision sensors and rugged pumps give reliable, accurate control, and FDA compliant tubing lets the pumps inject chemicals quickly and precisely.
Everything on the touch screen.
The large built-in color touch screen shows the sensor readings and every dosing setting.

What the BDX system includes:
Batch mixing tank not included.
Dosing Panel
BDX dosing panel, pre-assembled.
Main Pump
1/2 HP, 22 GPM recirculation and irrigation pump.
Pump Relay
RX1 outlet relay for the circulation pump.
Level Sensors
2 SXL high and low mix tank sensors.
Chemical Pumps
High-speed 480 ml/min peristaltic pumps.
The panels come pre-assembled: mount, plug in power and plumb the water connections. You supply the mixing tank and install the level sensors in the tank and plumbing.
Why batch dosing?
Batch dosing pre-mixes a batch of nutrient water and feeds it to crop zones or holding tanks once the mix is complete. Recipes use ml/gal, the same as most nutrient feeding charts, so setting one up is as simple as entering the manufacturer's schedule.
It is the safest approach to fertigation: every parameter is checked before the mix reaches the plants, so chemical outages or equipment faults are caught before they can harm the crop. On any error the BDX can pause, email several people and show a red alert on the screen.
- Batch checking for maximum deviation
- Dual sensor maximum differential monitoring
- pH failure to correct
- pH dosing in the wrong direction
- pH auto re-correct
- Failure to fill the tank
- Tank over-filled
- Main pump failure
- Component failure (dosing pump, sensors, valve driver)
Two Ways to Feed
Direct Feeding
Feed crop zones with drippers straight from the BDX. Ideal where crop steering is not used and a few irrigation events a day are enough.
Direct feed diagram ›
Stock Holding Tanks
Manage up to 10 holding tanks with their own recipes. A low-level sensor in each tank triggers a new batch; a GrowControl™ GCX or other irrigation controller feeds the zones. Ideal for many zones and crop steering.
Holding tank diagram ›Redundant Sensor Options
Precision, rugged probes made in the USA. With redundant sensors the BDX shuts down and alarms automatically if the readings differ by more than the allowed limit.

Motorized Ball Valves
Rugged motor-operated PVC ball valves designed and assembled in the USA: self-cleaning, high-torque Italian actuator with steel gearing, manual override, tested to well over 100,000 cycles.

Valve Expansion Panel
Eight-valve panel that brings a single BDX to 13 or 14 zones; connects to the base system's manifold and mounts on the wall.

Input Trigger Module
Adds eight inputs to the BDX's two; up to two DXI8 modules for 18 in total. Use them for holding-tank low levels, chemical outages, over-fill sensors or stop buttons.
