Growth Technology (GT) Super PK is a concentrated solution containing Phosphorus and Potassium (PK). Super PK is a plant nutrient additive for when plants are flowering or fruiting.Phosphorus is a component of the nucleic acids - Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA) which are important in cell multiplication and growth. Phosphorus is part of a molecule called Adenosine triphosphate (ATP) which is involved in energy transfer inside cells.  Also P is an important component of cell membranes where it plays a role in the interaction between the cell membrane surface and nutrients in the growing medium.Potassium which next to Nitrogen is the mineral nutrient required in the largest amount by plants. K is important in a plants ability to handle stress from environmental factors like pathogens, drought, frost etc. Potassium also plays a very important role in osmoregulation or the control of the amount of water inside cells.This means quality of fruits and flowers with their health and vitality, resistance to pests and diseases and even things like flavour of fruit. Super PK is all about the quality (not the quantity) of product produced by your plants improving the sweetness, aroma and flavour.BenefitsHigh quality PK supplement.Encourages heavy and bountiful yields in flowering plants.Promotes exceptional quality and taste.DirectionsGrowth Technology Super PK is a nutrient additive, so it is added to the nutrient solution. This is only done towards the end of the crop when the need for higher levels of PK develops. The maximum dose rate is 5mL of Super PK for each 1L of nutrient solution. This will add 0.7mL to the EC of the nutrient solution so it may be a good idea to cut the strength of the nutrients a bit although it isn’t totally necessary. With run-to-waste systems Super PK only needs to be added once when the nutrient solution is mixed. For recirculating systems dose the tank weekly.Available in 1L.
