What’s In The Bag?
Reefertilizer® Bloom
When plants begin to flower, their nutritional requirements change. Early on in flower, the plant will use its stored nitrogen for a quick growth spurt. After this short period , your plants will need nutrients with a higher ratio of phosphorus and potassium. These elements will fuel flower growth.
Reefertilizer Bloom also provides micronutrients such as calcium and magnesium. These two elements are common deficiencies and are proven to increase bud size and help terpene production. Each bag feeds up to 8 plants.

Common Question and Answers
Is Bloom Synthetic? Is that bad?
Reefertilizer Bloom is a synthetic fertilizer. Plants and soil microbes feed off the same elements provided by either organic or synthetic nutrients. A healthy living soil will maximize the amount of nutrients your plants can absorb.
Over-fertilization can be a issue but is easily fixed by flushing plants with water.
Bloom contains the highest quality chelated nutrients which are immediately available to plants and reduce wasted nutrients. Lower quality nutrients brands contain urea and other forms of nutrients that are not as easy to absorb and can end up in waste water runoff.
What makes Reefertilizer Bloom different from other bloom boosters?
Other bloom boosters usually need to be used with a full NPK fertilizer. Reefertilizer Bloom has a NPK ratio perfect for plants in flower as well as all the other micronutrients in bloom boosters.
Enhanced with calcium and magnesium, Reefertilizer Bloom reduces the number of additional inputs you might need.
