Buddhas Tree PK 9-18 Through pure biochemical innovation and an exhaustive focus on the highest standards of performance and safety, Buddhas Tree is proud to have achieved new heights in the creation of an EU-regulated, organically based PK 9-18 formula of outstanding quality and performance. It is the first truly soluble booster of its kind that is suitable for use with all growing media and soilless techniques. How It works The flower's cycle ends when it produces its seeds. Producing seeds takes a lot more potassium and phosphorus than is provided in the base nutrients. These extra elements allow for the creation of more extensive calyxes in unpollinated plants that do not produce any seeds. While the plant creates cells in its flower sites, the plant also uses potassium to improve Osmosis and increase its density. This ratio is very powerful, and was impossible before. It's due to the combination of ingredients in one bottle. This unique formula ensures that pH remains stable. How to Use Buddhas Tree PK 9-18 According to the Buddhas Tree Feed Chart, you should use this product from week three of flowering through to the final flush. This product can be used with any brand of base nutrition. Make sure to shake the container well before using it. Buddhas Tree 9-18 is more likely to break down in soil than other media, so a higher dosage may be required. Mix your soil-based feed water as normal and then add the PK booster to it at a rate equivalent to 0.3ml/L. Stir well. For the last 2 weeks, you can increase this dosage to 0.6ml/. You should only water with PK9:8 each time. Calmag products should be used before Pk 9-18. Calcium and Potassium are both antagonistic and your plants will require good access to each.
