General Hydroponics FloraKleen QT – Mineral Salt Clearing Solution
Over time, every hydroponic, soil-based or coco coir system can develop fertilizer residue as a natural part of the growing process. This accumulation can result in excess salts that will eventually cause your plants undue stress.
Clear those concerns and get a cleaner system with FloraKleen.
Specifically designed to dissolve fertilizer salts, our solution not only ushes excess residue, but also releases a nutrient bond between plants and the system. This connection helps plants make the most of remaining fertilizers, especially in the crucial week just before harvest.
