How King Kola Works

King Kola is a PK booster which delivers outstanding results all the way through the bloom stage. You can adjust the dosage to suit your needs, starting at a low level and gradually increasing it as you get closer to harvest. You should reduce the dose in the last week of flowering and then stop completely during the last week.

It is easy to use as soon as your lighting switches are switched to 12/12. King Kola can be added at this stage to help plants transition quickly from vegetative to 'flowering mode. This will speed up the time it takes to harvest. The good news is King Kola also helps to lay solid foundations. This is done by increasing the number of flower formations on the plant. This allows for greater yields later.

You can increase the amount of potassium and phosphorus as you progress through the flowering stage. This will cause your plants to produce larger and more nutritious fruits.

How to use King Kola

Include King Kola in your nutrient storage along with your other nutrients. After switching to a 12/12 light cycle, you can begin using it. You can start with a 1ml per Liter dosage and increase to 3.1ml per Litre during the middle of flower (weeks 4-5, on a 9-week cycle). You can then reduce the dosage and finish flushing in the last week. Click the link below to view the Emerald Harvest feed charts.
