Dead simple to cut to length, pushes on cleanly, and the black colour does exactly what it should. If you're running AutoPots and need to extend or replace pipe, this is the one.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eAutoPot 4mm flexi-pipe is the gravity-feed irrigation tubing designed specifically for AutoPot systems. Sold by the metre, you cut it to length and push it directly onto AutoPot's barbed connectors — no kits, no complications, no guessing. The 4mm internal diameter (6mm external) sits perfectly with AutoPot's AQUAvalve and tray setup, whilst the black lightproof construction prevents algae growth inside the lines, which matters when you're running a passive system that relies on staying clean.\u003c\/p\u003e\n\n\u003cp\u003eIt's tough, flexible, and easy to work with. If you're expanding an AutoPot system, replacing worn tubing, or setting up for the first time, this is the component that actually matters.\u003c\/p\u003e\n\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eThis is the system-specific option for AutoPot users.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePurpose-built for AutoPot barbed fittings — precision fit, no shaving or adapting needed\u003c\/li\u003e\n\u003cli\u003eBlack colour prevents algae as standard (vs. clear tubing which needs managing)\u003c\/li\u003e\n\u003cli\u003eSignificantly cheaper than buying complete AutoPot expansion kits if you only need pipe\u003c\/li\u003e\n\u003cli\u003e4mm size prevents blockages better than smaller tubing, reliable flow to individual drippers\u003c\/li\u003e\n\u003cli\u003eLarger 9mm AutoPot tubing available if you want more flow, but 4mm is the standard for individual pots\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSimple logic: if you're using AutoPots, use AutoPot pipe.

Push the flexi-pipe firmly onto the barbed connector ends — they'll sit tight and create a water-tight seal. Cut to length with a sharp knife or scissors. No glue, no fittings needed beyond what AutoPot provides.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSystem expansion\u003c\/strong\u003e\u003cbr\u003eOne of the smartest things about AutoPot is the flexibility to add pots incrementally. Buy tubing in lengths that suit your current setup, then add more metres as you expand. This is where buying by the metre saves money.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDuring the growing cycle\u003c\/strong\u003e\u003cbr\u003eFlush the system during transitions between growing phases. Hand water for the first few weeks until roots reach the bottom of the tray — then the AQUAvalve takes over and the system runs itself. Some growers add isolation valves and extra tubing lengths to make adjustments easier without draining the whole Header Tank.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMaintenance\u003c\/strong\u003e\u003cbr\u003eIf flow weakens, flush the lines. After harvest, clean the valves.

It's engineered for AutoPot systems, which means it fits right and works properly without any messing about.
