Cha Ching by Fox Farm is a high-phosphorus bloom booster formulated for the final weeks of the flowering stage. Containing a full spectrum of chelated micronutrients, kelp, and humic acid, it supports a healthy plant while delivering the concentrated phosphorus needed to drive intensive flower development and improve the quality of fruit and flower production. Leaves no salt or residue build-up in the growing medium. NPK 9-50-10 An extremely high-phosphorus formula designed specifically for late-stage flowering. The chelated micronutrient profile ensures full availability even in variable pH conditions, while kelp and humic acid support overall plant health and nutrient uptake efficiency. How to Use For use in hydroponics, aeroponics, soil, and soilless media. Begin applying once flowers are fully formed and continue through to the end of the flowering stage. Feed with every other watering. Breathable Lid Notice Fox Farm uses breathable lids on all liquid products. There is no inner seal — a small hole in the bottle cap allows live microbes to breathe. This is intentional and does not affect product quality.
