Info Specs Reviews

BAC Organic PK Booster is an additive to your plant fertilizer for the flowering phase that will guarantee the taste, odour and strength of your buds. Moreover, you will ensure the maximum harvest thanks to the increased sugar production that PK Booster creates.

PK Booster for Weed Plants

The purpose of a PK booster is to enhance the taste and increase the yield. P and K stand for phosphorus (P) and potassium (K) – two elements that are critically important for a vigorous weed plant. While phosphorus benefits the development of the root system and abundant buds, potassium facilitates the transport of nutrients to all parts of the plant. Potassium also facilitates strong cell structure and provides the initial stimulus to a rich flowering – the so-called preparedness to flower

Thanks to natural yucca, BAC PK Booster provides for stable water balance in both soil and coconut, and directly in the ground or in pots. Use PK Booster together with BAC Organic Bloom Fertilizer and Organic Bloom Booster for incredible results. See the recommended products on this page.
