PK Booster

Last updated: June 2, 2021

What Does PK Booster Mean?

PK boosters are nutrient supplements for flowering plants that are specifically designed to be used during middle and late stages of flowering periods. PK boosters are particularly high in phosphorus (P) and potassium (K), which is where the booster derives its name.

A PK booster simulates a natural chemical change inside a plant, particularly in the ends of the stems where flowers and fruits develop.

Maximum Yield Explains PK Booster

There are six main nutrients that are essential to healthy and fruitful development. The most essential of these nutrients are nitrogen (N), phosphorus (P), and potassium (K). As the name implies, PK boosters provide higher amounts of phosphorus and potassium but do not provide nitrogen. Most, but not all, growers contend that nitrogen during the flowering stage will compromise the size or quality of the buds.

PK boosters can have several different benefits when added to flowering/fruiting plants. Potassium is essential to healthy flowering and fruiting in plants while phosphorus aids in root development. When gardeners want to increase these nutrients, particularly during the flowering stage, they can use PK boosters. Some growers may use PK boosters to encourage a plant to flower at a much earlier time than it would naturally. Additionally, PK boosters can potentially improve the overall taste and quality of crops.

In cannabis cultivation, strains that take 5060 days will generally get an application of PK somewhere around week four. Strains that take 60–70 days will get a boost of PK at week five, but some growers may push it into the beginning of week six. Almost no grower will apply a PK boost after week six. These are just general guidelines and individual growers may apply a PK booster at different times of their choosing.

PK boosters are available in both liquid and concentrated forms.
