HEAVY 16 Prime, 1 gal

A Broad-Spectrum Base Nutrient for the Full Crop Cycle, 1 Gallon

Running a separate nutrient for every stage and every deficiency adds up to a crowded feeding schedule, and more bottles means more room for mixing error. HEAVY 16 Prime is a broad-spectrum liquid formulation designed for use across every stage of the crop cycle, from early establishment through harvest, built to work across aeroponic, hydroponic, and outdoor soil systems alike.

This 1 gallon bottle is sized for a regular indoor grower running a full room, supplying a wide base of plant nutrition that reduces the need for extra standalone additives while supporting color, flavor, and quality development as the crop matures.

Who Should Use HEAVY 16 Prime

Growers who want a single, broad-spectrum nutrient to simplify their feeding program across the full crop cycle, in soil, hydro, or aeroponic systems, will benefit from running HEAVY 16 Prime as their base.

About HEAVY 16

HEAVY 16 was formulated by Bryce Patterson, a Cal Poly-trained horticulturist based in Signal Hill, California, around three principles: high-grade raw ingredients, complex chemistry that simplifies application, and micro-batch blending for consistency. The line is built as a streamlined system — Bud A/B and Veg A/B base nutrients (both built with four calcium forms), plus Prime, Fire, Finish, Roots, and Foliar — designed to work across soil, coco, and hydroponic systems without a long list of separate additives.

Frequently Asked Questions

What stage of growth is HEAVY 16 Prime meant for?

Prime is designed for use throughout the full crop cycle, from early establishment through harvest, rather than being limited to one growth stage. That makes it the base nutrient a grower runs continuously alongside stage-specific HEAVY 16 products.

How do I use Prime across different growing systems?

Prime's chemistry is built to work across aeroponic, hydroponic, and outdoor soil systems, so the same product functions as the base feed regardless of setup. Follow the HEAVY 16 feeding chart rate for your specific system and container size.

Does Prime replace other additives?

Prime supplies a wide base of plant nutrition in a single product, which can reduce the need for some standalone additives depending on your program. It isn't meant to eliminate stage-specific products like Bud A/B, Fire, or Finish, which layer on top of it.

Can Prime be combined with other HEAVY 16 products?

Yes, Prime is formulated to serve as a base that can be paired with other HEAVY 16 products such as Veg A/B, Bud A/B, Foliar, or Fire, depending on the stage of growth. Most HEAVY 16 feeding charts build the schedule around Prime as the constant.

When should I start using Prime in a new grow?

Prime can be introduced from the earliest establishment stage and run continuously through harvest, since it's formulated as a full-cycle base rather than a stage-specific additive. Adjust the concentration as the plant moves between vegetative growth and flowering.
