General Hydroponics TrueFlo™ Irrigation Line Cleaner 32oz

Oxidizing System Hygiene & Flow Restoration — TrueFlo™ 32oz Irrigation Cleaner

General Hydroponics TrueFlo™ Irrigation Line Cleaner is an oxidizing, hypochlorous-acid-based formulation engineered to deep-clean irrigation systems used in indoor cultivation and commercial growing environments. Over time, drip lines, emitters, manifolds, and reservoirs accumulate mineral salt deposits, organic biofilm, and nutrient residue that restrict flow and reduce system efficiency. TrueFlo's oxidizing action dissolves and flushes these deposits, restoring flow and a clean system baseline for each new growing cycle.

TrueFlo is designed for use during system cleanouts between cycles, as a maintenance flush mid-cycle, or as a targeted treatment for clogged emitters and lines. The 32oz size is sized for growers who need this quantity for their system's maintenance schedule.

Key Features & Benefits

• Mineral Salt Dissolution: Breaks down calcium, magnesium, and other mineral salt deposits that accumulate inside drip lines, emitters, and fittings.
• Oxidizing Biofilm Removal: Its hypochlorous-acid-based oxidizing chemistry targets organic biofilm that colonizes reservoir walls, tubing interiors, and pump components.
• Nutrient Residue Flushing: Clears accumulated nutrient residues from system components, providing a clean starting point for each new crop cycle.
• Emitter & Dripper Maintenance: Safe for soaking clogged drip emitters and micro-sprinklers to restore flow.
• System Longevity: Regular use helps extend the service life of pumps, tubing, fittings, and reservoirs.

Who Should Use This

TrueFlo is useful for any grower using recirculating hydroponic systems, drip irrigation, NFT channels, ebb and flow tables, or aeroponics. Commercial indoor cultivation operations benefit from TrueFlo as part of a structured between-cycle maintenance protocol, and home growers using drip systems or flood tables will also see improved system performance.

Compatibility

TrueFlo is compatible with standard growing system materials, including PVC, polyethylene, and polypropylene tubing; rubber and silicone gaskets; and most reservoir, pump, and fitting materials. Always rinse the system thoroughly with clean water after use, before reintroducing plants or nutrients. Not intended for use as a plant nutrient or growing media amendment.

Frequently Asked Questions

When should I use TrueFlo in my growing cycle?

TrueFlo is most commonly used during the system cleanout between crop cycles, after harvest and before starting a new grow. It can also serve as a periodic maintenance flush mid-cycle if line clogging or buildup is observed, following label directions to avoid plant contact.

Is TrueFlo safe for my pump and irrigation fittings?

Yes. TrueFlo is formulated for compatibility with standard hydroponic system materials, including PVC, polyethylene, and polypropylene tubing, as well as most pump housings and fittings. Always follow label instructions regarding contact time and rinsing.

How long should I let TrueFlo soak in my system?

Soak time varies with the severity of mineral and buildup accumulation, so check the product label for specific contact-time guidance. For heavily fouled systems, a longer soak followed by multiple clean-water flushes gives the best results.

Can I use TrueFlo on clogged drip emitters?

Yes. TrueFlo works well for soaking clogged emitters and drip lines to dissolve mineral blockages and restore flow. Remove the emitters, soak them in a TrueFlo solution, rinse thoroughly, and reinstall.

Do I need to flush the system after using the 32oz size?

Yes, regardless of size. Thoroughly rinse your irrigation system with clean water after using TrueFlo and before reintroducing nutrient solution or plants, so no cleaner residue remains in the system.
