Bloom Booster for Bigger, Heavier Yields

Emerald Harvest King Kola is a powerful bloom booster designed to increase bud size, density and overall yield during the flowering stage.

With a targeted blend of phosphorus, potassium, nitrogen and amino acids, it helps plants bulk up properly in bloom – giving you heavier, denser flowers by the time you reach harvest.

If you want to push your plants to produce bigger results in flower, this is one of the key tools to do it.

Please Note - The 9.46L and 22.71L bottles are purchased to order, so extended lead times will apply

Key Benefits

• Increases bud size and density
• High phosphorus & potassium for flower development

Why You Need It

Once your plants hit flowering, they need more than just base nutrients to reach their full potential.

King Kola provides the extra PK and support needed to drive flower production, helping your plants pack on weight instead of stalling out mid-bloom.

How to Use

Use King Kola during the flowering stage alongside your base nutrients.

• Start: Transition into flowering
• Typical dose: 1ml – 3ml per litre
• Peak usage: Mid-flower (weeks 3–5)
• Reduce: Late flower before flush

Important: Do not aerate or use in bubbler systems.
