Modular grow tank rainwater collection system

The modularly designed rainwater harvesting system for planting troughs uses T-shaped sliding strips and troughs for splicing and positioning ball clamping, combined with a metal outer casing and a PP resin water storage liner. This solves the problems of rainwater waste and insufficient combination flexibility in traditional planting trough systems, achieving efficient rainwater collection and utilization, and improving the system's stability and applicability.
