Plagron PK Booster - Piles on Weight During the Bloom Phase

PK 13-14 provides a potent source of phosphorus and potassium, two crucial macronutrients that are in higher demand when plants start to move through the flowering stages. Adding phosphorus and potassium increases the number of flowering sites and the density of flower clusters, laying solid foundations for your plants to build on. These nutrients then help to increase the size and improve the quality of fruits further down the line.

Using PK boosters is a great way to add lots of extra weight to your harvest, and Plagron PK13-14 is up there with the very best.

It's a mineral based product product, and therefore not compatible with fully organic grow set-ups. Outside of that, you can use it in any medium or grow system.
