Humboldt Nutrients Ginormous PK Supplement - 1 Gal - 0-18-16

Phosphorus and Potassium for Flowering - 1 Gal

Plants in flowering draw heavily on phosphorus and potassium, and a base nutrient alone may not cover that demand. This PK supplement adds both macronutrients with a 0-18-16 analysis, so you can adjust feeding during bloom without adding nitrogen.

The 1 Gal bottle suits hobbyists and small to mid-size indoor growers who want to run a PK booster through a few flowering cycles. Larger operations can order multiple units as needed.

Key Features & Benefits

• 0-18-16 analysis — supplies phosphorus and potassium with no nitrogen.
• 18.0% available phosphoric acid (P2O5) — supports phosphorus demand during bloom.
• 16% soluble potash (K2O) — provides potassium for flowering plants.
• Monopotassium phosphate source — a soluble input material for liquid feeding.

Who Should Use Humboldt Nutrients Ginormous

Growers running flowering plants in indoor, hydroponic or container setups who want to supplement phosphorus and potassium during the critical blooming stages.

Frequently Asked Questions

Q: What does PK mean?
A: PK stands for phosphorus and potassium, two of the primary macronutrients. A PK supplement contains these without nitrogen, which is why the first number in the analysis is 0.

Q: What is the NPK analysis?
A: The analysis is 0-18-16. That is 0% nitrogen, 18.0% available phosphoric acid (P2O5) and 16% soluble potash (K2O).

Q: When should I use it?
A: It is designed for the critical blooming stages of flowering plants. It is not intended as a nutrient for vegetative growth, where nitrogen is usually needed.

Q: Can it replace my base nutrient?
A: No. A PK supplement adds phosphorus and potassium to a feeding program and does not supply nitrogen. Use it alongside a complete base nutrient.

Q: What is it made from?
A: It is derived from monopotassium phosphate, a soluble source of phosphorus and potassium.
