Project Needs

What do hydroponic/soilless cultivation projects typically need to address?

Hydroponic and soilless cultivation projects demand higher standards for nutrient solution stability, irrigation frequency, EC/pH control and system reliability, requiring more refined data monitoring and automated control.

EC

Unstable Nutrient EC/pH

EC/pH fluctuations affect crop absorption and growth; continuous monitoring and stable control are needed.

T

Difficulty in Precise Irrigation Frequency

Different crops, growth stages and substrate conditions require different irrigation frequencies and durations.

M

High Manual Management Workload

Manual nutrient solution testing, fertilizer adjustment and data recording are time-consuming and prone to errors.

P

Recirculation System Risks

Recirculation pumps, liquid levels, return flow and pipeline conditions require continuous monitoring to avoid shortage, overflow or clogging.

Z

Complex Multi-Zone Management

Different cultivation zones may correspond to different crops, formulations and irrigation strategies, requiring independent zone management.

IoT

Lack of Remote Monitoring and Alarms

Managers need to remotely view nutrient solution data, equipment status and tasks, and receive timely alerts.
