Proper co-extruded silicone, lightproof to keep algae out, and sold by the metre so you only pay for what you need. The kind of thing that makes system expansion actually simple.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eAutoPot 13mm Blue Flexi-Pipe is \u003cstrong\u003elightweight flexible irrigation tubing\u003c\/strong\u003e designed for gravity-fed hydroponic systems. With an internal diameter of 13mm and external diameter of 16mm, it carries nutrient solution from your header tank through the network of connectors and fittings that feed your plants. Sold by the metre, it's the go-to when you're scaling up, replacing damaged sections, or building custom pipe runs around your growing space.\u003c\/p\u003e\n\u003cp\u003eThe tubing is \u003cstrong\u003efood-grade co-extruded silicone\u003c\/strong\u003e, tough enough for regular use but flexible enough to navigate corners and tight spaces without needing elbow connectors. The blue opaque colour is the key detail here — it blocks light completely, which stops algae from colonising inside the pipe. That matters more than you might think when you're running nutrient solution through the same lines day after day.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eThis is the standard 13mm feed-line tubing for AutoPot systems.

Whether you're going from 1Pot to 4-pot or building out a full commercial operation, you just add more tubing to connect new modules to your existing header tank. The system scales as far as you want to take it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReplacement and repair\u003c\/strong\u003e\u003cbr\u003eIf a section gets clogged, kinked, or just worn out from months of nutrient running through it, replace that length without touching the rest of your system.
