Emerald Harvest King Kola

Faster than bovine protein

This bloom additive takes its strength from hemp, rather than more commonly-used bovine products. Plant-based protein is far more effective for mineral chelation, a process that makes it easier for plants to find nutrients and break them down. Thanks to its ability to speed plant metabolism, growers will reach a high-quality bloom stage in no time.

Faster, bigger blooming

King Kola is a bloom booster specially designed to achieve:

  • More abundant and productive flowering;
  • Larger, higher-quality fruits, vegetables, and flowers;
  • Naturally-occurring vegetable-based proteins.

Usually, this could only be achieved using 3 separate nutrients. Superior flowering no longer requires hours of gardening time or an extensive range of supplies - this one bottle is all you’ll need.

Derived from hemp seed flour

Plants need protein just like we do! King Kola is the first bloom booster derived from hemp seed flour, an all-natural ingredient that contains almost 25% protein. A protein-rich substrate ensures a regular supply of nutrients to plants. This helps them produce their own proteins for a longer lifespan and yields that are higher in quantity and quality.

Hemp requires very little water to grow and removes more CO2 from the air than trees - so you’re doing the Earth a favour, too.
