Who This Is For

  • You are switching to a liquid PK booster because you need the convenience of a pourable formula that won't clog lines.
  • You are introducing a 0-15-15 formula because you need to drive flower development without adding excess nitrogen.

What We Found

  • We suggest the liquid over the powder version for anyone using automated dosers that might clog with dry sediment.
  • The formula stays clear in the bottle even during winter, while other high PK boosters often turn into a salty mess.

What Users Say

  • Growers who stack this with G10 in mid-bloom say their final harvest weight is significantly higher than previous runs.
  • Users who previously fought nutrient lockout found this pure phosphate blend much easier on their root zone pH.

Humboldt County's Own Crystal Burst (0-15-15)

With dozens of bloom boosters flooding the market, most growers waste money on diluted formulas that deliver mediocre results. Humboldt County's Own Crystal Burst solves this problem by delivering a professional-grade 0-15-15 liquid bloom booster that's 50% stronger than the most popular competing products. When used alongside a high-quality base like Humboldt County's Own Deep Fusion Bloom, this maximum-strength potassium phosphate formula initiates explosive flower development, increases bloom size and mass, and stimulates resinous oil production.

Crystal Burst stands apart from competitors through its scientifically optimized concentration. While all effective liquid bloom boosters use potassium phosphate (KH₂PO₄) as their foundation, Crystal Burst is formulated at the highest possible concentration without crystallizing in cold temperatures. To push flower mass even further, many advanced growers stack this formula with Humboldt County's Own G10 during the mid-to-late flowering stages. The formula also includes substantial amounts of Vitamin B1 to help mitigate plant stress caused by high-performance feeding regimens during the critical flowering phase.

During the bloom cycle, plants demand massive amounts of phosphorus and potassium for maximum flower development. Crystal Burst delivers these essential macronutrients in their most concentrated liquid form available. The 0-15-15 analysis provides exactly what flowering plants need without excess nitrogen that could interfere with bloom production. Unlike products with pH levels above 7 that cause nutrient lock-out or require large amounts of pH down, Crystal Burst maintains optimal pH for immediate nutrient availability.

Application is straightforward and compatible with all nutrient brands. Apply Crystal Burst when you first observe signs of flower development—typically around the second week of bloom—and continue until approximately one week before harvest. Many growers flush during the final week to rinse excess fertilizer, though supplements like Humboldt County's Own Snow Storm Ultra, Purple Maxx, and Killer Tea are specifically designed for use through harvest to boost end-stage processes like resin production and swelling.

Important: Use either Humboldt County's Own Sonic Bloom OR Crystal Burst, not both products simultaneously. While Sonic Bloom delivers similar PK benefits, these two bloom boosters from Humboldt County's Own serve the same purpose with different formulations. Crystal Burst offers the advantage of liquid convenience, while Sonic Bloom uses a precision-blended powder format.

Beware of inferior products containing phosphites—compounds sometimes added to artificially inflate PK numbers. Phosphites do not provide usable phosphate and can actually damage plants at pH levels below 6. California law requires warnings on all fertilizers containing phosphites for this reason. Crystal Burst contains only pure potassium phosphate, ensuring every drop delivers genuine flowering nutrition.

Directions for Use

Application Rate: Use 1 teaspoon (5 ml) per gallon of water for both soil and hydroponic systems.

Timing: Begin application when you first observe signs of flower development, typically around the second week of the bloom phase. Continue feeding through the flowering cycle until approximately one week before harvest.

Flushing: Many growers flush during the final week to remove excess fertilizer buildup. While traditional flushing uses plain water, products like Snow Storm Ultra, Humboldt County's Own Purple Maxx, and Killer Tea are formulated to be used all the way to harvest for an extra boost to end-stage bloom processes.

Important Notes:

  • Works with all nutrient brands
  • Do not use flushing agents—they're unnecessary
  • Use either Sonic Bloom OR Crystal Burst, not both products together

Frequently Asked Questions

When should I start using Crystal Burst during the bloom cycle?+

Apply Crystal Burst when you first see signs of flower development, which typically occurs around the second week of the bloom phase. Continue using it throughout the flowering cycle until approximately one week before harvest. This timing ensures your plants receive maximum phosphorus and potassium during the critical bloom period when they need these nutrients most.

How is Crystal Burst different from Sonic Bloom?+

Both products are premium bloom boosters from Humboldt County's Own, but Crystal Burst is a liquid concentrate while Sonic Bloom is a powder. Crystal Burst offers the convenience of liquid feeding and is formulated at the highest possible concentration without crystallizing in cold temperatures. Use one or the other—never both together—as they serve the same purpose with different delivery formats.

Can I use Crystal Burst with my current nutrient line?+

Yes, Crystal Burst is designed for universal compatibility and works seamlessly with all nutrient brands in both soil and hydroponic systems. Simply add 1 teaspoon per gallon of water to your regular feeding schedule. The optimized pH ensures it won't cause nutrient lock-out or require excessive pH adjustment like some competing products.

Why is Crystal Burst 50% stronger than other bloom boosters?+

Crystal Burst achieves maximum concentration by using pure potassium phosphate (KH₂PO₄) formulated to the highest level possible without crystallizing when cold. This 0-15-15 formula contains significantly more active ingredients per bottle than lower-concentration competitors, meaning you get more flowering power per dollar spent. Many competing products are diluted or contain filler ingredients that don't contribute to bloom development.

Should I flush before harvest, and can I use Crystal Burst during flushing?+

Many growers flush during the final week before harvest to rinse excess fertilizer from the growing medium. Stop using Crystal Burst approximately one week before harvest. If you want to boost end-stage bloom processes like resin and fragrance during the final week, consider using products specifically designed for late bloom like Snow Storm Ultra, Purple Maxx, or Killer Tea instead of traditional water flushing.

What are phosphites, and why should I avoid them in bloom boosters?+

Phosphites are compounds sometimes added to bloom boosters to artificially inflate PK numbers on the label, but they don't provide usable phosphate nutrition. Worse, phosphites can actually damage your plants when used at pH levels below 6, which is why California law requires warnings on products containing them. Crystal Burst contains only pure potassium phosphate—no phosphites—ensuring safe, effective flowering nutrition.

How does the Vitamin B1 in Crystal Burst help my plants?+

High-performance feeding regimens during bloom can stress plants as they work to produce maximum flowers. The substantial amounts of Vitamin B1 in Crystal Burst help mitigate this stress, allowing plants to better handle aggressive feeding schedules. For even greater stress management and oil production, many growers also integrate Humboldt County's Own Deep Breath into their schedule.

Do I need to use a flushing agent with Crystal Burst?+

No, flushing agents are unnecessary and a waste of money. Crystal Burst is formulated for clean feeding without excess salts or additives that require special removal. If you choose to flush before harvest, plain water works perfectly fine—there's no benefit to purchasing expensive flushing products.
