Perfectly Balanced Blends for Veg and Flower
Plants in veg have different nutritional needs then when they’re in flower. In veg, they need lots of nitrogen to grow quickly and turn sunlight into sugars through photosynthesis.
During flower, nitrogen takes a backseat to phosphorus and potassium. Reefertilizer Bloom provides this ratio as well as beneficial micronutrients like calcium and magnesium that help flower and terpene production.

Balanced Nutrition for Cannabis Plants
Reefertilizer Grow
A recipe for faster cannabis growth
Reefertilizer Grow contains the essential nutrients required to establish strong stems, good leaf structure, and healthy root systems. Grow is a chelated synthetic nutrient that allows elements to be metabolized immediately, much faster than organic fertilizers.
These essential elements and added micronutrients help fuel many cell functions crucial to photosynthesis and cellular replication.

Reefertilizer Bloom
Crafted for flowering cannabis plants
When cannabis 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 growth spurt, your cannabis plants will need nutrients with a higher ratio of phosphorus and potassium. These elements will fuel flower production.
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.
