Humboldt Nutrients Big Up Powder - 0-33-23 Bloom Booster - 10 lb

Phosphate and Potash for a Strong Finish - 10 lb Bulk Powder

Plants entering flowering need more phosphorus and potassium than vegetative growth requires, and a general-purpose feed rarely supplies enough. This bloom booster powder fills that gap with a 0-33-23 analysis: 33% available phosphate (P2O5) and 23% soluble potash (K2O), with no nitrogen.

The 10 lb size suits growers who run bloom cycles regularly, whether in a multi-tent indoor room or a larger hydroponic setup. A powder also stores compactly and lets you mix to the strength your feeding plan calls for.

Key Features & Benefits

• 0-33-23 analysis — concentrates phosphate and potash for the flowering stage without adding nitrogen.
• Monopotassium phosphate source — supplies both phosphorus and potassium in one ingredient.
• Ascophyllum nodosum — a seaweed-derived ingredient included in the plant food formula.
• 2% humic acid from Leonardite — listed as a non-plant food ingredient.
• Powder form — mixes into feed solutions for soil or hydroponic systems.

Who Should Use Humboldt Nutrients Big Up Powder

Growers who want a dedicated phosphorus and potassium supplement for flowering and fruiting will find it useful. It suits home gardeners with a steady bloom schedule and commercial operations that want a larger quantity in one unit.
