Mills Ultimate PK Booster

Mills Ultimate PK Booster 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. 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
