Rock Resinator Heavy Yields, 5 L

Phosphorus and Potassium Support Through Late Flowering, 5 L

Rock Resinator Heavy Yields (5 L) blends phosphorus and potassium sourced from refined natural base elements and plant extracts, carrying a 0-7-8 guaranteed analysis formulated to support size and weight development as plants move through flowering toward harvest.

Because the formula is concentrated, dosing is adjusted by reservoir EC, giving growers a way to fine-tune feeding strength to their existing nutrient program.

Key Features & Benefits

• 0-7-8 guaranteed analysis — concentrated phosphorus and potassium for flowering and finishing.
• Refined natural base elements — sourced along with plant extracts for the formula.
• EC-based dosing range — allows feeding strength to be tuned from 4 to 8 ml per gallon.
• Available in 1 L, 5 L, and 20 L — sized to match grow room scale and feeding schedule.

Who Should Use This Additive

Growers in the second week of flowering through harvest who want a targeted phosphorus and potassium boost layered onto their existing base nutrient program.

About Rock Nutrients

Rock Nutrients is a nutrient brand distributed through Hydrofarm's catalog. Rock Resinator Heavy Yields carries a 0-7-8 guaranteed analysis and is formulated as a flowering-stage additive rather than a base nutrient.

Frequently Asked Questions

When should I start using this product?

Start in the second week of flowering, and continue dosing through harvest. Starting earlier isn't necessary, since the formula is built for the phosphorus-and-potassium-heavy demand of later flowering.

How is the dose determined?

Dosing ranges from 4 ml per gallon at lower EC up to 8 ml per gallon at higher EC. Adjusting within that range lets you fine-tune feeding strength against your existing base nutrient program.

Do I need to shake it before use?

Yes, shake well before each use to ensure the blend is evenly mixed. Settling can occur in concentrated liquid additives, so a quick shake keeps dosing consistent bottle to bottle.

What is the guaranteed analysis?

Rock Resinator Heavy Yields carries a 0-7-8 (N-P-K) guaranteed analysis. That phosphorus- and potassium-heavy ratio is what targets late-flowering nutrient demand.

Is this meant to replace my base nutrients?

No, it is designed as a flowering-stage additive layered onto an existing base feeding program. Keep running your regular base nutrients and add Rock Resinator on top during the flowering window.
