I'm looking to source various irrigation materials specifically designed for hydroponic and aquaponic systems. We need products that are durable, efficient, and suitable for both fresh and saltwater environments. Additionally, if you have options that support automation and water conservation, that would be a plus. Please provide catalogs, pricing, and any relevant specifications that can help us make informed decisions. Looking forward to your prompt response!
