Emerald Harvest King Kola 0.3-2-3 | 1gal (FL, NM, PA)

Bloom-Phase Booster for Budding, Floral Development, and Ripening, 1gal (FL, NM, PA)

The later stages of flowering put extra demand on a plant's ability to finish developing buds and ripen fruit, a window some growers find their base nutrient alone doesn't fully cover. Emerald Harvest King Kola 0.3-2-3 is a bloom-phase booster formulated to support budding, floral development, and ripening, layered onto whatever base nutrient program a grower is already running.

This 1gal size is labeled and registered specifically for use in Florida, New Mexico, and Pennsylvania, and growers in those states should use this listing rather than the standard 1gal version.

Key Features & Benefits

• 0.3-2-3 NPK content — a light booster ratio meant to layer onto a base nutrient rather than replace it.
• Budding support — targets the stage when flower buds are actively forming.
• Floral development focus — supports the plant through the bulk of the flowering window.
• Ripening-stage use — carries support through to the finishing stage as buds and fruit mature.
• Universal program compatibility — works alongside any base feeding program or schedule, including both Cali Pro and Grow, Micro, Bloom.

Who Should Use King Kola

This booster fits growers already running a base nutrient program through the bloom phase who want additional support specifically for budding, floral development, and ripening.

Frequently Asked Questions

Do I still need my base bloom nutrient if I add King Kola?

Yes, King Kola is a bloom-phase booster meant to layer onto an existing base nutrient program, whether that's Cali Pro Bloom, Emerald Harvest Bloom, or another brand's feed. It doesn't replace the core nutrition a base feed provides.

When during the bloom phase should I start using King Kola?

Start once flowering begins and continue through budding, floral development, and ripening, since the formula is built to support the plant across that full window rather than one narrow point in it. Check the Emerald Harvest feed chart for specific rate timing.

Why does this product have a separate 1gal listing for certain states?

Some states require product-specific registration before a fertilizer or supplement can be sold there, and this 1gal listing is the version registered for sale in Florida, New Mexico, and Pennsylvania. Growers in those three states should order this listing instead of the standard 1gal version.

Is King Kola compatible with the Cali Pro system as well as Grow, Micro, Bloom?

Yes, it's formulated to work alongside any base feeding program or schedule, so it pairs with either Emerald Harvest base system. It's built as an add-on booster rather than a component tied to one specific base line.

What does the 0.3-2-3 ratio tell me about how to use this product?

The low overall numbers, especially the 0.3% nitrogen, indicate this is a light booster meant to supplement an existing feed rather than supply primary nutrition on its own. Follow labeled dilution rates rather than treating it as a standalone base nutrient.
