Humboldt Nutrients Big Up Powder - 0-33-23 Bloom Booster - 20 lbs

Phosphorus and Potassium for Flowering Support - 20 lb Bag

Plants in flowering demand more phosphorus and potassium than they did in vegetative growth, and a feed program that falls short can limit late-stage performance. Big Up Powder supplies both in a concentrated powder with a 0-33-23 analysis: 33% available phosphate (P2O5) and 23% soluble potash (K2O). It is derived from monopotassium phosphate and Ascophyllum nodosum.

The 20 lb bag suits growers who run flowering cycles regularly, whether in a home indoor space or a larger operation. A bulk powder keeps the supply on hand across many feedings.

Key Features & Benefits

• 0-33-23 analysis — delivers phosphate and potash with no nitrogen in the formula.
• Monopotassium phosphate source — provides phosphorus and potassium together in one input.
• Ascophyllum nodosum — a seaweed-derived ingredient included in the formula.
• Humic acid from Leonardite — a non-plant food ingredient at 2%.
• Powder form — stores compactly and is mixed as needed.

Who Should Use Big Up Powder

Growers who want to add phosphorus and potassium during flowering, in soil or hydroponic systems, and who use enough product to justify a 20 lb bag.

Frequently Asked Questions

Q: What does 0-33-23 mean?
A: The three numbers show nitrogen, available phosphate (P2O5) and soluble potash (K2O). This product has no nitrogen, 33% phosphate and 23% potash.

Q: Can I use it in hydroponic systems?
A: The manufacturer describes it for use in soil or hydroponic systems. Follow the label for mixing and feed rates, and check your reservoir's nutrient levels as you go.

Q: Does it replace a complete nutrient?
A: No. With no nitrogen, it is an additive that supplements a base nutrient program rather than replacing one.

Q: When in the cycle is it used?
A: It is intended for flowering, when plants draw more phosphorus and potassium. Follow the label for timing.

Q: What is humic acid doing in the formula?
A: Humic acid is an organic compound derived here from Leonardite. It is listed as a non-plant food ingredient at 2%.
