What are PK boosters, and what are they used for?
PK boosters are specially formulated nutritional supplements containing phosphorus (P) and potassium (K), two essential elements during the flowering phase of cannabis. Unlike base fertilizers, PK boosters are used as intensive support to achieve more explosive floral development and more abundant flower and trichome production.
Phosphorus stimulates flower and root formation, while potassium improves sugar transport and overall plant resistance. Together, they enhance bud growth and ripening.
When and how are PK boosters used?
These products are generally applied starting in the third or fourth week of flowering, depending on the variety. Some are used only during peak flowering, while others can be spread out over several weeks to maintain the blooming momentum. They are diluted in the irrigation water and combined with the base flowering fertilizer.
It is advisable to always follow the manufacturer's instructions to avoid excesses and ensure a balanced diet.
What types of PK boosters will you find here?
- Highly concentrated liquid formulations, ideal for a fast and powerful effect.
- Organic and bio-mineral PKs, compatible with organic crops.
- Combinations with amino acids or enzymes, which further strengthen the plant's metabolism.
- PK for hydroponic and coco systems, for fast absorption.
Who are they ideal for?
These supplements are essential for growers looking to maximize yields indoors or outdoors. They're especially useful if you want denser buds, better aroma, more resin, or simply to maximize the genetic potential of your plants.
Benefits of using PK boosters
