PK Boosters

PK Boosters are often considered an essential element in any growers arsenal of nutrients and additives. PK boosters are particularly high in phosphorus (P) and potassium (K)P which are the building blocks required for plants to flourish and fruit during flowering. They most commonly come in two varying ratios, PK 13/14 and PK 9/18. PK boosters are available in both liquid and concentrated forms with some brands offering drastically higher ratios of PK. Choose the right PK for you to get the best yields, flavour and quality from your crops!
