Supernutes Power B 5 Gallon (Liquid)
Supernutes Nutes B is a ready-to-use liquid concentrate specifically formulated to complement Power A for complete plant nutrition. This clean, concentrated liquid delivers enhanced levels of phosphorus and potassium essential for maximum flower production, oil output, and flavor intensity. The liquid format provides the convenience of pre-mixed nutrients while maintaining the precision potassium control that drives flower stacking and metabolic strength during bloom. Perfect for growers who want the performance of the Power system with the operational efficiency of liquid nutrients.

Product details
What It Does
Power B is the second half of the Super Nutes two-part base nutrient system. It delivers essential macronutrients and chelated micronutrients—phosphorus, potassium, and more—to support strong vegetative growth and early flowering. Designed for hydroponics and soilless systems, it works best alongside Power A.
Why It Works
- Balanced PK and micronutrient blend ensures full-spectrum nutrition
- Chelated minerals remain accessible to plants even under fluctuating pH
- Clean, sediment-free liquid formulation prevents clogging in drip lines and dosing systems
- Two-part flexibility lets growers optimize A:B ratios as plants transition from veg to bloom
How to Use It
- Mix Rate: 1–2 mL per liter (3.8–7.6 mL per gallon) of water
- When to Apply: Throughout vegetative and early bloom stages
- Usage Tip: Add nutrients separately in water, shake well, adjust EC/pH, and use alongside Power A for best results
- Systems Compatibility: Ideal for hydroponic, coco, and soilless setups
Good to Know
- Combined with Power A, it forms a complete base-feed system from seedling to bloom
- Highly concentrated and clean—no residue or clogging
- pH-balanced for simplicity—little adjustment needed
- Available in durable 5-gallon jugs—perfect for commercial and large-scale operations
FAQs
Are Super Nutes products safe for all grow systems (hydro, coco, soil, etc.)?
Yes! All Super Nutes products are designed to work seamlessly in hydroponic, coco, soilless, and soil-based systems. They’re clean, fully soluble, and won’t clog lines or drip emitters when used as directed.
Can I mix Super Nutes with other nutrient brands?
While Super Nutes are formulated to work best as a complete system, many growers successfully integrate individual products into their existing nutrient regimens. Just be sure to monitor pH and EC levels carefully and avoid ingredient overlap (like excess calcium or nitrogen).
What’s the difference between the liquid and dry (25 lb) versions?
The liquid versions are ready to mix directly into your reservoir for quick use. The 25 lb dry products are highly concentrated powders intended for stock solution prep, large-scale dosing systems, or commercial operations looking for cost efficiency and bulk control.
How should I store Super Nutes products?
Store all products in a cool, dry, and dark place. Keep containers tightly sealed to prevent contamination or degradation. For dry nutrients, avoid moisture exposure. For liquids, shake well before use.
Where can I find a full feeding schedule or mixing chart?
You can access the full Super Nutes feeding chart and dosing guidelines on our website’s Resources section — or reach out to our team anytime for help building a custom schedule based on your setup.
Do I need to pH my water after mixing Super Nutes?
Yes. While Super Nutes formulas are pH-balanced, it’s always recommended to test and adjust pH after mixing, especially in hydroponic and coco systems. Ideal pH ranges:
Hydro/Coco: 5.5–6.2
Soil: 6.0–6.5
Can I use Super Nutes with tap water or RO water?
Yes. Super Nutes performs well with both, but RO (reverse osmosis) water may require added calcium, magnesium, or silica. Products like Super Mag and Super Silica are ideal companions.
What’s the shelf life of Super Nutes products?
When stored properly (cool, dry, sealed), Super Nutes products have a shelf life of 1–2 years. Keep dry powders moisture-free and always shake liquids before use.
Can Super Nutes be used throughout the entire grow cycle?
Yes — when used together, the Super Nutes lineup covers everything from veg through harvest, including base nutrients (Power A & B), additives (Sweet, Mag, Silica), and bloom boosters (Swole).
Do I need to flush when using Super Nutes?
Yes. A flush is recommended 1–2 weeks before harvest to remove residual nutrients and enhance flavor. Super Clean can be used as a system cleaner or media rinse to assist with this.
Will Super Nutes stain or clog my lines?
No. All Super Nutes products are designed with clean, low-residue formulations that won’t clog emitters, injectors, or drip lines when mixed and used correctly.
Can I mix Super Nutes directly into my reservoir or do I need stock tanks?
You can do both. Liquid products can be mixed directly into your reservoir. Dry products (25 lb) are intended for stock tank prep and dosing systems, but can be batch-mixed if dissolved properly.
Do I need to use the full Super Nutes lineup?
No — while the full lineup is optimized to work together, you can start with base nutrients (Power A & B) and add products like Swole, Mag, Sweet, or Silica as needed based on your crop and grow method.
Are Super Nutes safe for organic or living soil grows?
Super Nutes are mineral-based nutrients, not certified organic. While they may work in some amended or hybrid setups, they’re designed for hydroponic, coco, or soilless media.
Where can I get help with building a feeding schedule?
