PK SPIKE

PK Spike is a flowering supplement derived from multiple, highly soluble sources of phosphorous and potassium. This product is designed to encourage budding, help facilitate bulking, and ripening of flowering plants.

HOW IT WORKS: PK Spike is engineered to provide a uniform quantity of phosphorus and potassium to your flowering plants. Designed with over 25% more P/K than the next industry leading competitor, this product can be applied at a maximum rate of 1.0 ml/L to achieve a 250 ppm boost to your plants.

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

During the flowering stage, phosphorous plays a key role in the essential functions of the plant that benefit flower formation. It helps the plant perform photosynthesis, transfer energy, and easily uptake the nutrients essential for budding. Added potassium helps convert phosphorous into energy that your plant can use and strengthens cell walls to support heavy flowers. Stronger cell walls support plant health by boosting the plant’s immunity response to pathogens and attacking pests.

HOW TO USE IT:

Add at a rate of 0.5 – 1 ml/L to your reservoir.

Apply from the 2nd week of bloom every 2 weeks until 1 week before flush. Applying PK Spike at the recommended rate will deliver up to a 250 PPM boost to your plants, adjust your nutrient strength accordingly

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 starch and carbohydrate synthesis, which is essential in the development of large and healthy photosynthesis organs.
  • A potash deficiency may lead to reduced cell wall strength, which can lead to the breaking of stems, leaves, and susceptibility to the toppling over and breaking of heavy branches.
  • Phosphate deficient plants take longer to initiate flowering, produce fewer flowers, and are restricted in flower size.
  • Phosphate deficiencies can result in a reduction in leaf expansion and also the number of leaves.

My Favorite Flavored Sparkling Water
Flavor Name: Black Raspberry, Size: 17 Fl Oz (Pack of 12)
Sparkling Ice Black Raspberry has honestly become my favorite flavored sparkling water. The flavor is strong enough to actually taste satisfying without being overly sweet, and it has a really refreshing balance compared to many other zero-sugar drinks. One thing I especially like is that it feels much more enjoyable than plain water while still avoiding the heavy sugary feeling that comes with regular soda. The carbonation level is also good in my opinion because it gives the drink a crisp texture without feeling overly aggressive or flat. The black raspberry flavor stands out nicely and does not have the strange aftertaste that some zero-sugar drinks tend to develop. It has consistently been one of the easiest flavored waters for me to keep buying regularly. I also appreciate the added vitamins and the convenience of having a flavorful alternative available when trying to avoid higher-calorie drinks. Overall, this has easily been my go-to sparkling water, and I would highly recommend it to anyone looking for a flavorful zero-sugar drink option that still feels refreshing and satisfying.

My Go-To Beverage
Flavor Name: Black Raspberry, Size: 17 Fl Oz (Pack of 12)
Black Raspberry Sparkling water is my go-to drink. The taste is not too sugary and the carbonation is not too strong. I have this on auto delivery and often order additional cartons when I run out too quickly. It's also much better priced at Amazon than at the grocery stores near me. I also like the fact that I don't need to lug it home. Added vitamins make this a got-to-have product.
