King Kola. By Emerald Harvest. 

There are bloom boosters, and then there’s Emerald Harvest King Kola - the undisputed heavyweight in a world where size, speed, and intensity matter. Created by the expert cultivators at Emerald Harvest in the sun-drenched greenhouses of California, King Kola is a plant-based powerhouse that turns an average bloom cycle into a full-on floral explosion. Whether you’re working with a low-profile cupboard grow or running a high-output hydroponic fortress, King Kola is engineered to dominate every stage of flowering with ruthless efficiency.

The Crown Jewel of Boosters.

What immediately sets Emerald Harvest King Kola apart is its unique foundation - hemp seed flour. Unlike traditional boosters that rely on animal-derived ingredients, King Kola uses this sustainable, protein-rich source to give your plants the metabolic equivalent of a double espresso. At nearly 25% protein content, hemp seed flour accelerates growth and bolsters nutrient uptake by enhancing mineral chelation. That’s the fancy way of saying your plants absorb what they need, when they need it, and use it better. The result? Faster transitions from vegetative growth to bloom, and a much shorter wait for a spectacular harvest.

Drive Flower Formation. Promotes Swelling.

Once your lights flip to a 12/12 cycle, Emerald Harvest King Kola takes over like a conductor leading a botanical symphony. With an NPK ratio of 0.3-2-3, it delivers a potent balance of nitrogen, phosphorus, and potassium tailored specifically for flowering. The nitrogen gives early structural support, while phosphorus and potassium drive flower formation and fruit swelling. It’s this precise tuning that causes buds to explode with density and colour, producing rich, heavy blooms that push the limits of your system - and your expectations.

For Big Flowers & Big Flavours.

But King Kola isn’t just about brute force. It’s clever too. By fuelling the production of internal plant proteins, it enhances longevity and resilience, ensuring your plants don’t just flower hard, but flower smart. This makes it an ideal choice for indoor growers battling with confined environments where space is tight but performance expectations are sky-high. And because it’s derived from naturally renewable hemp, you’re getting all the power without the ethical baggage of livestock-based alternatives.

Made In California. 

Used properly, Emerald Harvest King Kola is as straightforward as it is effective. Just follow the feeding schedule - starting at 1.0ml per litre and peaking at 3.0ml in mid-bloom - and you’ll be guiding your grow through every phase of flowering with pinpoint precision. It plays nicely with all mediums, from soil and coco to the most complex hydroponic rigs. And for maximum effect, pair it with Honey Chome to create a one-two punch of structure and scent that will blow your floral competition out of the water.

Setting The Standard.

With four bottle sizes available - from 0.95 to a grow-room-ready 9.46 litres - there’s a King Kola for every type of grower. It’s the ultimate flowering enhancer for those who don’t want to compromise on quality, yield, or sustainability. Packed with natural protein, rich in bloom-boosting minerals, and powered by Californian know-how, Emerald Harvest King Kola doesn’t just raise the bar. It is the bar.
