AutoPot 13mm Blue Flexi-Pipe — Lightweight Irrigation Tubing for Modular System Expansion
Best for: Growers extending or upgrading their AutoPot systems without replacing entire irrigation setups
Our thoughts
If you're running an AutoPot system and need to add plants or replace worn tubing, this is the straightforward answer. 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.
AutoPot 13mm Blue Flexi-Pipe is lightweight flexible irrigation tubing 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.
The tubing is food-grade co-extruded silicone, 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.
How it compares
This is the standard 13mm feed-line tubing for AutoPot systems. How it stacks up:
- Lightproof design — algae can't grow inside like it can in clear tubing
- Metre markings printed on the pipe for dead-easy measuring and cutting
- Compatible with the full range of 13mm AutoPot fittings, connectors, and accessories
- Works for both small setups (expanding a single-pot system) and larger operations (building out multi-plant configurations)
- Costs significantly less than buying pre-assembled irrigation kits
Generic 13mm tubing will physically fit, but you lose the system integration, the algae protection, and the durability that comes with proper co-extruded material. Worth the difference if you're running an AutoPot system properly.
Usage guidance
This tubing forms the backbone of your nutrient delivery. Here's how growers typically use it:
System expansion
Buying extra flexi-pipe is the standard way to scale your AutoPot setup. 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.
Replacement and repair
If 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. No need to dismantle everything.
Custom routing
Unlike rigid pipe, this flexes enough to go round corners and follow the shape of your growing space. That means tighter layouts in grow tents, greenhouses, and small rooms without adding extra connectors.
Connection to fittings
The 13mm internal diameter works with all standard AutoPot 13mm barbed fittings — tee connectors, cross connectors, inline filters, and the 4mm outlet adapters. Push the tubing on, tighten the jubilee clip, and you're done.

Who this is for
- AutoPot users adding plants to their existing setup without buying a whole new system
- Growers replacing damaged or clogged sections of their current irrigation lines
- Anyone building a custom multi-pot configuration in a specific space
- Commercial operations scaling from small hobby setups to larger production systems
- First-time AutoPot buyers who want to start small and expand as confidence grows
In particular, this is essential kit for anyone who's discovered that AutoPot systems are genuinely modular — you add tubing and connectors, and your system grows with you. No redesign needed. That scalability is the whole point.
Our take
This is a straightforward component that does exactly one job well — delivering nutrients reliably from your header tank to your plants. The lightproof material keeps algae at bay, the metre markings make it impossible to cut wrong, and it flexes where you need it to flex. Proper kit, sensible design, none of the faffing about.
If you're running an AutoPot system and either need to fix something or expand your setup, this is worth picking up. Buy the length you need, stick it in, clip it down. Good time to grab it while stock lasts.
