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.
