The A⁺-green (HPAG-8001) is an integrated smart farm environmental control system supporting greenhouse location-based astronomical and standard time modes. It offers flexible control options including composite control, temperature control, or a combination of both, with automatic proportional and integral control index assignment. The system enables 1 to 4 cycle period settings with coordinated nutrient solution supply control, and integrates the environmental control program with the nutrient solution feeder program in a unified platform. It supports both linked and independent operation scheduling for nutrient solution feeders during composite environmental control, and provides multi-access environments via mobile app, PC dashboard, and on-site control panel.

The Agrow-6000 Plus is a smart farm nutrient solution feeder supporting PC program and smartphone remote control with 10 channels. It operates with 4 independent programs — 3 dedicated to solar radiation and 1 for substrate moisture content and external sensors — performing individual operations based on cumulative solar radiation from a single sensor. Solar-dedicated programs automatically apply solar (light) coefficient Ec000% and moisture coefficient f000%. The system comprises 4 nutrient solutions (A–D), acid/base, and supplement fertilizer totaling 6 lines, with 16 irrigation valves each operating independently by time or flow-based volume selection. A dedicated program (pro-i) supports substrate moisture content control and temperature display. Standard equipment includes 1 Ec sensor, 1 pH sensor, alarm and safety functions, and sensor calibration. The Option Type additionally supports a supplement fertilizer supply unit for selective feeding across 1–16 valves. Available options include a flow meter, solar sensor, Ec-2/pH-2 re-treatment sensors, and Ec-3/pH-3 drainage sensors.

The Agrow-5000 Master is a 2024 new model smart farm nutrient solution feeder featuring 3 independent nutrient control programs — 2 solar radiation (2-stage) control programs and 1 moisture content control program. It includes 2 EC-pH group control programs and 1 EC-pH valve-specific control program. The standard display is a 7-inch touchscreen LCD, with a base nutrient configuration of Solution A, B, acid/base, and supplement fertilizer. The Option Type expands to Solutions A, B, C, and D plus acid/base and supplement fertilizer. The system supports 12 irrigation zones with solar radiation-based supply, moisture rate-based supply, interval/scheduled time supply, and external signal-triggered operation. The supplement fertilizer uses a direct injection method with no effect on the mixing tank's EC or pH values. The irrigation pump is a stainless steel 3HP (2.2KW) horizontal continuous mixing type. Standard safety features include phase failure protection, low water level alarm, irrigation/source pump fault detection, and EC, pH, and flow rate alarms.

The Agrow-2000Star is a 2024 new model EC-controlled fertigation feeder with continuous mixing supply. It is the industry's first fertigation feeder to feature 2 independent built-in programs, enabling separate operation for solar radiation control and moisture content control. The system includes 1 group-based EC control program and 1 valve-specific EC control program, supporting 12 irrigation zones with time and flow-based supply per valve. Built-in programs support pre-irrigation source water supply, post-irrigation source water supply, and pre-irrigation valve delay functions. Operation modes include solar radiation-based supply, moisture rate-based supply, interval and scheduled time supply, and external signal-triggered operation. The standard display is a 7-inch touchscreen LCD with a built-in EC control sensor. The irrigation pump is a stainless steel 2HP (1.5KW) horizontal continuous mixing type. Standard safety features include irrigation/source pump fault detection, EC alarm, and flow rate alarm. Optional add-ons include a solar sensor, moisture sensor, flow meter, supplement fertilizer unit, source water pump, and irrigation solenoid valves.

The Agrow-7000 Plus is a high-performance smart farm nutrient solution feeder supporting PC program and smartphone remote control with 10 channels. It operates with 5 independent programs — 3 dedicated to solar radiation and 2 for moisture and external sensors — performing individual operations based on cumulative solar radiation from a single sensor. Solar-dedicated programs automatically apply solar (light) coefficient Ec000% and moisture coefficient f000%. The system comprises 6 nutrient solutions (A–F), acid/base, and supplement fertilizer totaling 8 lines, with 16 irrigation valves. Nutrient supply mode can be selected between proportional-integral control or composite proportional control per program, with the composite mode enabling deviation-based supply per nutrient component (A–F) at 10–90%. A supplement fertilizer supply unit allows selective feeding across 1–16 valves, and dedicated programs (pro-4/pro-5) support substrate moisture content control and temperature display. Standard equipment includes 2 Ec sensors (control and detection) and 2 pH sensors (control and detection), with a tank flush and nutrient solution preparation function when switching programs for multi-crop cultivation. Optional add-ons include a flow meter, drainage flow meter, Ec-3/pH-3 re-treatment sensors, Ec-4/pH-4 drainage sensors, Ec-5/pH-5 substrate sensors, and a solar sensor.
