Buddhas Tree PK 9-18 is an all natural, highly concentrated Phosphorus (P) and Potassium (K) supplement to be used from week 2 of the bloom cycle right through until flush.

PK 9-18 by Buddhas Tree is a liquid soluble solution that works by breaking down enzymes in the root zone, this helps increase the absorption rate of available nutrients, along with giving the plants a boost of Phosphorus (P) and Potassium (K), two vitally important elements that are required in abundance to help achieve, not only healthy plants and intense aromas, but also to push yields to their potential and beyond, with test grows to claim an impressive 40% increase when using PK 9-18.

Developed by one of the top biochemist in the world, Buddhas Tree PK 9-18 has gone through vigorous development and testing to ensure that the formula contains no synthetic additives, used to help stabilise pH, keeping the supplement 100% organic and that it conforms to the strict EU guidelines for safe to use food grade fertilisers.

Buddhas Tree PK 9-18 is not a nutrient solution and should be used alongside your normal base flowering feed, whether it Shogun, Canna, Plant Magic Plus, VitaLink, or any of the available fertilizer, PK 9-18 will complement these by helping to enrich the P and K levels during bloom, resulting in healthy plants with an abundance of fruits and flowers.


  • 100% organic food grade PK supplement
  • Increases absorption rate of PK enriched nutrients
  • Increases plant health, aromas and final yields
  • Can be used in soil, coco and hydroponic systems


0.25ml per litre from week 2 of bloom, then increase to 0.5ml for the final 2 weeks prior to flush.

Please note:
Buddhas Tree PK 9-18 is a highly concentrated supplement so please use the recommended dilution rates in order to keep your plants healthy.
