Reviews & Questions

Buddhas Tree PK 9-18 is a highly concentrated PK booster. This effective supplement is a bloom stimulant that works on the principle of providing elevated levels of potassium and phosphorus to your plants during the flowering process. This additive offers the chance to dramatically increase yields as well as improvements to taste, aroma and terpene profile of your end crop. Buddhas Tree PK 9-18 is the only stable formulation in this 1:2 ratio currently on the market.

Buddhas Tree PK 9-18 ensures your plants get exactly what they need and it promises to boost yields by up to 40% when compared to using only base nutrients. This might sound like a bold statement; however it is backed up by countless hydroponic growers who choose this nutrients as part of their permanent nutrient schedule.

How it works

At the end of a plants cycle, the flower will produce its seeds. The production of seeds requires substantially more phosphorus and potassium than what is available in a base nutrient. In an unpollinated plant that is not producing seeds in the flowers, these extra elements facilitate the production of larger more expansive calyxes throughout all the flower sites. The plant uses the phosphorus in creating cells within the flower sites themselves, whilst the potassium, which is stored in the cells, improves the process of Osmosis, increasing the density of your flowers.

The ratio of 9:18 is extremely powerful and it was previously impossible to produce; due to the compatibility of the ingredients in one bottle at such a concentrated strength. The pH is always ensured to be stable as a consequence of this unique formula.

How to use Buddhas Tree PK 9-18

The Buddhas Tree Feed Chart recommends use from week 3 of flowering, right through to final flush. You can use this product with and brand of base nutrient. Ensure you shake the bottle well before use and for hydroponic systems, make up your normal base nutrient and add Buddhas Tree PK 9:18 at a rate of 0.25ml/L and mix well.

Buddhas Tree PK 9-18 will break down a lot faster in soil than any other growing media and because of this a slightly higher dose is required. If you choose to grow in soil, you will need to mix up your feed-water as usual and add this PK booster at a rate of 0.3ml/L and mix very well. This dosage can also be increased to 0.6ml/ for the final 2 weeks only before flush. Make sure your only use PK 9:8 every second watering.

It is also recommended that you use a Calmag product before and alongside with Pk 9-18, as both Potassium and Calcium are antagonists of each other and to achieve optimal growth your plant will need good access to both.

Buddha Tree PK 9:18 is available in 100ml, 250ml, 1L and 5L bottles and works particularly well alongside Buddhas Tree Organicus, Solar Green Power and Flower Burst, to complete the exceptional hydroponic nutrient & additives range from Buddhas Tree.

Good range of nutrients

Tried quite a few over the years. I stuck with Nutrifield for a long time but the downside to it is some of the additives are quite thick and can clog up the lines and tanks. This is on par with ease of use and price but without heavy thick boosters.
