How Ultimate PK works:

Ultimate PK is ideal for the later stages of flowering, as it is Phosphite-based and therefore increases oxygen flow to the root. The Phosphite is readily soluble and this helps to stimulate root growth as well as harden cell structure.

Following extensive scientific research into what nutrients are needed to produce a successful harvest, Ultimate PK was created. It works quickly to increase the production of essential oils, which help to enrich your plant’s flavour and aromas, and acts as a hardener and ripener for your plants.

When in flowering mode, higher levels of phosphorous and potassium are needed to develop stronger, larger, and harder fruits. Using Ultimate PK increases those levels, which leads to an increased yield.

It uses clean and super soluble mineral salts, and it also stops any final stage diseases from destroying your crop. This fantastic PK booster is compatible with all growing mediums

Using Ultimate PK:

Ultimate PK is to be used in the last 2-4 weeks of flowering, at 1.6 ml per litre.

It must be kept at room temperature, and make sure that you do not allow it to freeze or else it you will ruin the booster’s ability to work efficiently.

Ultimate PK must be kept out of reach of children, and is harmful if it comes into contact with your eyes. Avoid ingesting or breathing in the product, as it could be corrosive and harmful to your health if swallowed. Avoid direct heat, fire, or contact with your skin, as prolonged exposure could cause irritation.
