Bloom Boosters

Bloom boosters give your plants just what they need when they need it to produce abundant, vigorous blossoms and better harvests. Offering an effective macro-nutrient balance usually higher in phosphorous and potassium — two nutrients that support flowering — they also include additional trace minerals, amino acids and other stimulants to replenish growing solutions and prevent weakness, deficiencies and disease. You’ll marvel at the results.
