Humboldt Countys Own Sonic Bloom is the most Concentrated PK Booster on the market that works with all nutrient brands!
During the flowering cycle, plants require large amounts of Phosphorus and Potassium for maximum development. The primary ingredient of Sonic Bloom is potassium phosphate (KH2PO4), and we use the most concentrated, highest quality source available.
Soil and Hydro: Use just 1 tsp/5 gallons of water! Apply when you first see signs of flower development, usually around the 2nd week of bloom, and continue until a week before harvest.
For best results continue to apply Snow Storm or Purple Maxx and Killer Tea during flush.
NOTE: USE SONIC BLOOM OR CRYSTAL BURST, NOT BOTH!
