Reset your system for a cleaner, healthier grow
General Hydroponics TrueFlo™ Irrigation Line Cleaner is the ultimate solution for maintaining a clean irrigation system and hydroponic equipment. This powerful, hypochlorous-acid–based cleaner removes mineral scale and organic buildup (biofilm), helping you reset your equipment for a successful crop and smoother irrigation performance.
TrueFlo™ is safe for plants (at recommended usages) and for all common growing equipment. Use it to clean lines, emitters, reservoirs, trays, pumps, and injectors/dosers across drip, NFT, DWC, ebb-and-flow, and recirculating systems—perfect for greenhouse and indoor cultivation.
Why Growers Choose TrueFlo™
- Cuts through scale and biofilm to keep emitters flowing and lines clear.
- Plant-safe at recommended rates, giving peace of mind during active growth.
- Fast turnaround between crops using Line Shock and Surface Cleaner modes when no plants are present.
- Versatile system maintenance for fertigation lines, day tanks, and hydro reservoirs.
- Supports consistent irrigation to reduce clog-related issues and improve distribution uniformity.
