Description
FLORAKLEEN 5 LITRE is the concentrated mineral salt and nutrient residue clearing solution from General Hydroponics Europe designed for mid-cycle salt clearing, system maintenance cleaning, and pre-harvest flushing in hydroponic and all growing media systems. We have been recommending FloraKleen to UK growers since 2017 as a versatile, effective clearing solution that addresses salt accumulation in both plant tissue and growing media throughout the production cycle.
Why Salt Accumulation Management Is Critical for Crop Quality and System Longevity
Mineral salt accumulation is an inevitable consequence of intensive nutrient feeding — salts delivered in concentrations higher than immediate plant uptake will precipitate and accumulate in growing media pores, on equipment surfaces, and within plant cellular tissue. In the growing media, accumulated salts progressively raise the substrate EC, reducing the osmotic driving force for root water uptake and causing the salt stress symptoms that manifest as tip burn, leaf curl, and growth slowdown. In plant tissue, residual minerals affect the taste, smoothness, and overall quality of the harvested product. FloraKleen’s surfactant-based formula is specifically designed to solubilise accumulated mineral salts and flush them from both substrate and plant tissue, making it valuable both as a periodic mid-cycle salt management tool in extended crop cycles and as the final pre-harvest clearing solution that maximises product quality. The 5-litre format provides commercial-scale volume for growers managing multiple systems.
Application Protocols, Timing, and System Compatibility
For mid-cycle salt management, use FloraKleen at the manufacturer’s recommended dilution for one watering event every two to four weeks in extended crop cycles, or when EC run-off significantly exceeds EC input indicating salt accumulation. For pre-harvest flushing, replace your nutrient feed with FloraKleen solution for the final one to two weeks before harvest. FloraKleen is compatible with all growing media — soil, coco, rockwool, clay pebbles — and all hydroponic system types. In recirculating systems, add to the reservoir during the flush period and circulate normally. The 5-litre format is cost-effective for commercial operators and large-scale home growers who run multiple crop cycles through the season.
