Humboldt County's Own Sonic Bloom w/ Vitamin B1 - Powdered PK Booster - 50 lb

Concentrated Powder Bloom Feeding for High-Volume Rooms - 50 lb

Plants in flowering draw heavily on phosphorus and potassium, and many growers want a booster that does not add another bulky liquid to the feed routine. This powdered formula uses potassium phosphate as its primary ingredient and includes Vitamin B1. It is dosed at just 1 teaspoon per 5 gallons of water, so a small amount treats a lot of reservoir volume.

The 50 lb unit is sized for commercial operations and large multi-room indoor gardens that mix nutrient solution at volume. Smaller gardens may prefer a smaller container, since this unit holds a large quantity of powder.

Key Features & Benefits

• Potassium phosphate base — supplies phosphorus and potassium during flowering.
• Vitamin B1 included — adds an extra component to the feed.
• Powdered form — stores and measures by the teaspoon rather than by liquid volume.
• Low dose rate — 1 teaspoon per 5 gallons of water.

Who Should Use Humboldt County's Own Sonic Bloom

Commercial growers and serious indoor gardeners who run soil or hydroponic systems and want a powdered flowering-stage booster in bulk.
