The original and still the flagship product from the Buddhas Tree range, PK 9/18 is one of the very best flowering boosters on the market. The super concentrated formula contains the perfect ratio of phosphorus and potassium for superior flowering performance. Enormous yield increases of 40% plus have been recorded just by adding this product to the nutrient schedule.

How It Works

It is well known how important phosphorus (P) and potassium (K) are during the flowering stage. Years of research and experimentation as helped us understand how PK enrichment in flowering leads to increased yields and other positive effects on fruits and flowers. Through vigorous testing it is clear best elemental ratio for PK additives on plants is 9/18 or 1:2. However producing a bloom boosting PK supplement to this specification that can be used both hydroponically as well as on soil and coco is particularly challenging. Fortunately Buddhas Tree have been able to work alongside one of the top four chemists in the world, who specialises in horticulture and produces fertilisers for many of the worlds record breaking food crop suppliers. Combining this in-depth knowledge with years of growing experience from the Buddhas Tree team, they are proud to have produced an EU regulated and organically based PK 9-18 formula that is capable of delivering outstanding quality and performance from your prized plants. The formula is completely soluble and free from synthetics. What is important to note is PK enrichment must be available at the ratio of PK 9-18 to the plant, this means by weight and NOT by volume of any given solution. Other PK boosters often have their ratios calculated by volume meaning the actual elemental ratio is usually outside the optimum range. Buddhas Tree calculates by weight so you can rest assured your plants are getting exactly what they need. The use of high quality ingredients means PK 9/18 is effortlessly absorbed by the roots and tissues of your plants and delivered to the flowering sites. The organic inputs stabilise the pH of the solution and bring the whole thing together into a powerful formula that will give explosive fruit formation with never before seen density and massive increases in essential oils, terpene and resin production. Yield, taste, aroma are all maximised.

How To Use Buddhas Tree PK 9/18 

PK 9/18 is for use during the later part of the flowering cycle, with most users starting at around week 4. Buddhas Tree recommend a dose of 0.25-0.5ml per litre. It can be used with all types of growing media and any hydroponic or watering systems. The solution is highly soluble and will not block any pipework. For best results use PK 9/18 as a follow on from Buddhas Tree Flower Burst

PK 9/18 works well alongside other products, but should not be used at the same time as other PK booster additives. Use with Solar Green Power and Advanced Meta-Boost from the Buddhas Tree range for a complete and high performance solution to flowering.

Buddhas Tree PK 9/18 is available in 100ml, 250ml, 1L and 5L bottles.
