One of the most concentrated PK bloom boosters on the market:


  • Increases the size and mass of flowers.
  • Stimulates resinous oils and fragrance production in many culinary and medicinal herbs.
  • Initiates and stimulates profuse flower development.
  • Large amounts of Vitamin B1 to help mitigate the stress caused by high performance bloom regimens.

All liquid bloom boosters are pretty much the same ingredient:  Potassium Phosphate.  Some throw in a few other ingredients for “label dressing”. 

  • What matters is the PK number (0-15-15). Crystal Burst is as concentrated as it can be made without it crystallizing when it gets cold.  Products with higher numbers usually have a pH above 7 which can cause nutrient lock-up or require large amounts of pH down in order to work properly.
  • Beware of products containing Phosphites which are sometimes added to boost PK numbers.  Phosphites do not add usable Phosphate and can actually damage your plants at a pH below 6.  California law REQUIRES warnings on Phosphite labels.
