- Optimum Phosphorus and Potassium ratio for maximum flower potential
- Includes Plant Sterols and other natural ingredients to maximise nutrient uptake and utilisation
- Targeted nutrition for the reproductive phase of crops
- Manufactured using high grade agro-chemicals and specific organic acids
- Suitable for use in all growing systems
Add at a rate of 0.5 – 1.0ml/L to your nutrient reservoir or watering can.
Use from the fourth week of the flowering cycle (or when flowers and fruits begin to form) and for a period of four weeks. Using in conjunction with Sumo Boost will maximise your plants demand for PK Warrior 9/18.
The need for a PK type product during in flowering is obvious. You are trying to alter the NPK ratio of your nutrient solution to maximise its efficiency for fruit and flower production.
We’ve carried out extensive field trials and scientific studies to work out the ratios of phosphorus and potassium to include in our product. In general, most nutrient manufacturers have a 13/14 formulation – our trail data indicated that this was far from optimum. Most nutrient solutions, specifically bloom formulations are already carrying relatively high phosphate levels and despite this being an important flowering element you need to avoid oversupply as your plant will struggle to use and store excess supply resulting in fruit quality decreases.
Potassium on the other hand is the element that drives sugar production in your fruits and it is this element that your plants need in a higher proportion from your PK product. After large scale testing using a multitude of PK ratio products, we found that the 9/18 ratio offered the optimum level of potassium uptake without overloading on phophorus in the process. This also allows our PK product to be used for longer during the flowering period without negative effect, feeding the need for yield enhancing potassium for as long as possible.
Optimising Your Solution
A common mistake by many growers when they come to adding products to their nutrient solution is that they continue to add nutrients at full strength alongside their boosters and additives. This can often lead to over fertilisation. In fact by the time you are adding PK warrior to your nutrient solution, you should actually be REDUCING nutrient strength by 20-50% for optimum plant performance. This may seem counter-intuitive, but by the time your plants are producing fruits and flowers, the overall nutrient requirement of your plant is actually less and the transpiration rate of your plant is often higher than during leaf and stem growth. This higher rate of water loss from your plants will result in more nutrient solution being taken up by your plant to compensate – if the nutrient levels are too high then over fertilisation will occur due to the increased uptake rate.
Doing the maths
PK Warrior is highly concentrated and dilutes at just 1mL/L in the first week of use and then 0.5mL/L from that point forward. Compare that with the leading competitor products and you will rapidly see that the cost per litre of diluted product at full strength makes PK Warrior massively more economical to use than pretty much any competing product. And that’s before you compare performance between the products.
