Description
Dense buds. Big terpenes.
When plants start to flower their needs change: after a short growth spurt on stored nitrogen, they need more phosphorus and potassium to fuel flower growth.
Bloom delivers that ratio, enhanced with calcium and magnesium — two common deficiencies that help bud size and terpene production. No more mixing A and B liquids.
Easy flower feeding schedule
Feed weekly through flower and flush with plain water for the last one to two weeks before harvest.
Stabilizers in the powder may not fully dissolve — they break down naturally and won’t harm plants or irrigation.
How to mix and feed Bloom
Measure
Use the scoop in the bag to measure Bloom for this week.
Dissolve
Stir it into a small glass of warm water until dissolved.
Feed
Mix into the rest of your water and feed, or add to your reservoir.
Why Bloom works
Dense buds, big yields
High phosphorus and potassium with low nitrogen — the ratio flowering plants want.
More terpenes
Calcium and magnesium support bud size and essential-oil production.
One powder
Everything for flower in one bag, for soil or autopot-style systems.
