Lower nutrient temps = fewer problems, healthier plants. Icetube does it passively, costs nothing to run, and the effect is noticeable. One we recommend a lot to growers running DWC, flood \u0026amp; drain, or R-DWC systems.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eIcetube 25mm Flexi Pipe is a \u003cstrong\u003edual-core irrigation tubing\u003c\/strong\u003e designed to keep nutrient solution cooler as it travels through your hydroponic system. The white reflective outer layer bounces heat and light away from the pipe, while the black inner core blocks UV penetration. The result: nutrient temperatures stay lower without you having to do anything. Just cut it to length, fit it, and let it work.\u003c\/p\u003e\n\u003cp\u003eThis matters because when nutrient temps climb above 21°C, dissolved oxygen drops sharply and your reservoir becomes a breeding ground for root rot and pythium. Icetube growers report temperature reductions of up to 3°C just by switching from standard black pipe—or up to 15% cooler than ambient room temperature. That's passive cooling that actually works.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eSeveral ways to control nutrient temperature.
