General Hydroponics FloraKleen is exactly what you need to scrub your hydroponic system, potting soil, and soilless substrates of built-up residual fertilizers. It ensures your nutrients remain balanced, as excess fertilizers and salts safely dissolve away — even while plants are growing.
Designed for monthly use, FloraKleen is also safe to use during a system flush up to one week before harvest. It helps to release the nutrient bond between your plants and the system. FloraKleen is suitable for use for all types of soils and grow media, including Rockwool, potting mix, coco, in-ground plantings, and hydroponics.
