Reefertilizer® Bloom
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 short period , your cannabis 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.

What Do Our Customer Think Of Reefertilizer Bloom?
Questions and Answers
Are synthetic fertilizers harmful?
Microbes in soil feed off the same elements provided by organic or synthetic nutrients. Avoiding over-fertilization and maintaining the right soil pH will keep soil microbes happy. Organic inputs like Reefertilizer Start will feed the microbes in your soil.
When overused, synthetic fertilizers can end up in wastewater adding to agricultural runoff. That’s why having healthy soil is important. In healthy soil, plants are able to absorb more nutrients meaning you end up with less in your waste 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 cannabis 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.
Our goal at Reefertilizer is to get more folks growing their own cannabis. Reefertilizer provides easy-to-use and affordable nutrients along with straightforward guidance and support.

When do I start feeding my plants Reefertilizer Bloom?
When you start to see flowers begin to form around the nodes (where the branch meets the stem) you can switch to feeding your plants Bloom. For autoflowers, this is usually 3 or 4 weeks in. For outdoor plants, this is usually around July or August in the northern hemisphere.
How much do I feed my plants?
Start with 1 scoop (5ml) for every 4L (1 gallon) of water. Feed each plant weekly with enough of this solution to fully saturate the soil and have a bit of runoff. You can water your plants as needed in between feedings. Some folks split the dose and feed twice a week. Both work fine, pick whichever method is easier for you.
When I mix the Bloom powder it doesn’t dissolve completely, what gives?
What you’re seeing are left over stabilizers in the powder. These stabilizers are inert, completely safe, and won’t harm your plants or injectors. They will slowly break down over time in your soil or coco mediums.
Can I pre-mix these nutrients?
Because these are chelated nutrients they don’t do well being mixed into water and stored for long periods of time. The elements within the solution can react with each other and lower the effectiveness of the fertilizer. A few days is okay, but anything longer than a week might not be a good idea.

Best stuff I ever used. These nutrients kept my plant alive and no yellow leaves at harvest time even after flushing with water only for the last two weeks. My buds were nice and big and firm and smelled great too. I credit my grow to the nutrients from this website REEFERTILIZER and will be using these nutrients for as long as I’m around lol and their around as well. Now I’m smoking the finished product and the smell and flavor of the buds are spot on I highly recommend these nutrients they are safe and do the job they are supposed to and easy to use as well.
