Green Planet PK Spike 1L 

When to Use: Apply from the 2nd week of Flowering Cycle. 

PK Spike is engineered to provide a uniform quantityof phosphorus and potassium to your flowering plants. Designed with over 25% morePK than the next industry leading competitor, this product can be applied at amaximum rate of 1.0 ml/L to achieve a 250 ppm boost to your plants.

What it is:

PK Spike is our flowering supplement derived frommultiple, highly soluble sources of phosphorous and potassium. This product isdesigned to encourage budding, help facilitate bulking, and ripening offlowering plants.


Available Phosphate(P2O5)………………………14.0%

Soluble Potash (K2O)……………………………….15.0%

Derived from: MonopotassiumPhosphate, Potassium Acetate, Potassium Citrate, PotassiumMetaphosphate.

Key Features:

  • Improved flower formation and seed production.
  • Earlier and more uniform crop maturity.
  • Improvements in crop quality.
  • Along with phosphate, potash is instrumental in starchand carbohydrate synthesis, which is essential in the development of large andhealthy photosynthesis organs.
  • A potash deficiency may lead to reduced cell wallstrength, which can lead to the breaking of stems, leafs, and susceptibility tothe toppling over and breaking of heavy branches.
  • Phosphate deficient plants take longer to initiateflowering, produce fewer flowers, and are restricted in flower size.
  • Phosphate deficiencies can result in a reduction inleaf expansion and also the number of leafs.

How it works:

PK Spike is derived from several highly solublesources of phosphorus (P) and potassium (K) to deliver high amounts of PK toflowering plants.

During the flowering stage, phosphorous plays a keyrole in the essential functions of the plant that benefit flower formation. Ithelps the plant perform photosynthesis, transfer energy, and easily uptake thenutrients essential for budding. Added potassium helps convert phosphorous intoenergy that your plant can use and strengthens cell walls to support heavyflowers. Stronger cell walls support plant health by boosting the plant’simmunity response to pathogens and attacking pests.

Potassium is also responsible for tightening up airyand loose flowers that plants lacking in K develop. The result is a healthyplant that will produce your heaviest yields yet.
