Description
Humboldt County’s Own Cystal Burst is one of the most concentrated PK bloom boosters on the market!
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.
Humboldt County’s Own Cystal Burst Features:
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.
