General Hydroponics Flora Kleen – Gallon

General Hydroponics FloraKleen is a liquid salt-clearing concentrate designed to remove fertilizer residues that accumulate over time in recirculating hydroponic systems, inert growing media such as rockwool and clay pebbles, and conventional potting soils. Use it monthly as a preventive purge or at the end of a crop cycle as a final flush to strip away mineral deposits before harvest or replanting.

Why Choose General Hydroponics FloraKleen

FloraKleen addresses a routine maintenance problem in hydroponic growing: salt and mineral deposits that build up in reservoirs, irrigation lines, drip emitters, and media over weeks of fertilizer application. Left unchecked, these accumulations can restrict water flow, skew nutrient ratios, and stress plants by elevating root-zone EC above intended levels. Here is what makes FloraKleen a practical tool for this job:

• Targets fertilizer residues specifically: Formulated to break down the salt compounds that form when concentrated hydroponic nutrients contact reservoir walls, media, and grow-system components over time.
• Works across system types: Suitable for recirculating deep water culture, NFT channels, drip systems, ebb-and-flow tables, and hand-watered containers using coco, rockwool, perlite, or potting soil.
• Dual-purpose — monthly maintenance or end-of-cycle flush: Use it mid-grow on a monthly schedule to prevent buildup, or run it through the system at the end of a crop cycle to strip residuals before replanting or harvest.
• Dissolves mineral deposits: Beyond salt accumulation from fertilizers, FloraKleen can clear mineral scale (from hard water sources) that adheres to tubing and reservoir surfaces.
• One-gallon volume supports extended use: The gallon format provides enough volume for multiple flush cycles across a season without frequent reordering.

Best Uses for General Hydroponics FloraKleen

FloraKleen is most useful at predictable points in the grow cycle and as part of a standing maintenance routine. The following use cases are drawn directly from the product’s stated applications:

• Monthly reservoir and system purge: Run FloraKleen through the reservoir and recirculating lines once per month during an active grow to prevent excess salt accumulation before it can affect plant health or clog emitters.
• Pre-harvest final flush: Use as the last solution run through the root zone in the final days of a flowering cycle to clear residual fertilizer salts from the media before harvest.
• Growing media reset between cycles: Flush inert media such as clay pebbles, rockwool, or perlite with FloraKleen solution between crop cycles to remove salt deposits and prepare media for reuse.
• Potted plant salt purge: Apply to container plants in potting soil that show signs of salt accumulation (white crust on media surface, slow growth despite feeding) to strip excess salts from the root zone.
• Irrigation line and drip emitter clearing: Run through drip irrigation systems to dissolve mineral deposits that can restrict flow at emitters or accumulate inside tubing.
• Hard water scale management: In areas with high-mineral water, use periodically to address lime and mineral scale in reservoirs and fittings — particularly useful when running a reverse osmosis system as the first filtration stage and FloraKleen as downstream maintenance.

Compatibility

FloraKleen is designed for use with the types of substrates and systems found in commercial and home hydroponic operations. Based on the manufacturer’s stated product applications:

• Hydroponic systems: Compatible with all common recirculating and run-to-waste hydroponic configurations — DWC, NFT, ebb-and-flow, drip, and aeroponics.
• Growing media: Works with inert hydroponic media including rockwool, clay pebbles (hydroton), perlite, vermiculite, and coco coir.
• Potting soils: Suitable for use with conventional and amended potting soils in container applications.
• General Hydroponics nutrient program: Designed as a maintenance complement to the General Hydroponics Flora Series and other GH nutrient lines, though it is not nutrient-program-exclusive.

For growers monitoring EC and pH throughout the flush cycle, pairing FloraKleen with a calibrated EC meter such as the Apera GroStar GS3-E EC electrode allows verification that residual salt levels have dropped to target levels before reintroducing nutrients or proceeding to harvest.
