Organic PK booster

When your plants enter the flowering stage, they require extra phosphorus (P) and potassium (K). This is where PK in this product’s name comes from. 

Potassium strengthens the metabolism of a plant, allowing for increased sugar formation. In turn, your crop will taste and smell better and the overall health of your plants will improve. Potassium also increases the immune system of your plants. 

Together with phosphorus, it strengthens the root system. By adding both nutrients during the flowering stage of your crop, your plants will develop close-knit, resin covered buds that will grow into exuberant flowers. 

BAC Organic PK Booster improves taste and scent

Contrary to artificial ones, BAC PK Booster is entirely natural. High amounts of trace elements and sugars enable this nutrient to join forces with soil bacteria and Mycorrhizae. The latter are fungi that have entered a symbiosis with the plants. They help increase the plant’s ability to take up water and nutrients, in this case the potassium and phosphorus. In exchange, they receive nutrients from the plant. 

Available in 250 ml, 500 ml, 1 litre and 5 litres.
