Humboldt County's Own Sonic Bloom w/ Vitamin B1 - Powdered PK Bloom Booster - 5 lb

Concentrated Powdered PK Support for Flowering - 5 lb

Plants in flowering draw heavily on phosphorus and potassium, and many feed programs leave them short late in the cycle. This powdered booster supplies both from potassium phosphate (KH2PO4), its primary ingredient, and adds Vitamin B1. You dose it by the teaspoon, so you can adjust it for each reservoir or watering.

The 5 lb container suits regular indoor growers and small commercial rooms that run several reservoirs through a flowering cycle. If you want to trial a powdered booster, the low dose rate stretches one container across many feedings.
