4mm Iceline White Pipe – Sold Per Metre

Think your irrigation pipe doesn't matter? It does. Iceline 4mm pipe is the upgrade most growers don't know they need – until they switch. Standard black pipe absorbs heat. In a warm grow room, that means your nutrient solution heats up as it travels – and warm solution means less dissolved oxygen, weaker roots, and a higher risk of root disease. Not ideal. Iceline sorts it. The white outer layer reflects heat away, while the black inner layer blocks light and UV – stopping algae growth inside the pipe too. You're looking at a temperature drop of 3–8°C vs standard pipe. That's huge. Cooler solution. More oxygen. Healthier roots. Better yields. Job done. Sold per metre – so you buy exactly what you need, nothing more. Dual-layer construction – white outer reflects heat, black inner blocks UV and light Temperature reduction of 3–8°C vs standard black pipe More dissolved oxygen in your nutrient solution Reduced risk of root disease – including Pythium and other pathogens Prevents algae growth inside the pipe More stable pH and EC levels UK manufactured Flexible PPVC – easy to route around any system 4mm inner diameter / 7mm outer diameter Sold per metre Autopot users – heads up Iceline is slightly thicker than standard Autopot flexi pipe – 7mm outer diameter vs the standard 6mm.
