Humboldt Nutrients Big Up Powder - 5 lb - 0-33-23 Bloom Booster

Phosphate and Potash for a Stronger Finish - 5 lb Powder

Plants entering flowering need more phosphorus and potassium than they did in vegetative growth, and a general-purpose feed often falls short. Big Up Powder is a bloom booster built around those two nutrients, with 33% available phosphate (P2O5) and 23% soluble potash (K2O). It also contains 2% humic acid as a non-plant-food ingredient.

The 5 lb size suits regular indoor growers and small operations that supplement bloom feeding through a full cycle. Hobbyists who want to try a bloom booster will find it a practical amount, and commercial growers can use it for supplemental feeding.

Key Features & Benefits

• 33% available phosphate (P2O5) — supports energy transfer and root development during flowering.
• 23% soluble potash (K2O) — supports overall plant health and water balance.
• Monopotassium phosphate source — supplies phosphorus and potassium together.
• Seaweed-derived input (Ascophyllum nodosum) — adds a plant-derived component to the formula.
• Powder form — stores compactly and is mixed as needed.

Who Should Use Humboldt Nutrients Big Up Powder

Growers who want to add phosphorus and potassium during flowering will get the most from this product. It fits soil and hydroponic cultivation, and works for both newer and experienced gardeners.

Frequently Asked Questions

Q: What is the NPK analysis?
A: The analysis is 0-33-23. That means no nitrogen, 33% available phosphate (P2O5) and 23% soluble potash (K2O).

Q: Can I use it in hydroponic systems?
A: The product is intended for use in soil or hydroponic systems. Follow the label for mixing rates and check your reservoir's concentration as you feed.

Q: Why does this product contain no nitrogen?
A: It is a bloom booster meant to supplement a base nutrient program. Your base feed should supply nitrogen and other nutrients.

Q: What does P2O5 mean?
A: P2O5 is the standard way fertilizer labels express available phosphate. K2O likewise expresses soluble potash.

Q: When should I use a bloom booster?
A: Growers generally apply one during flowering, when plants have higher phosphorus and potassium demand. Follow the label for timing.
