How to use Reefertilizer Start Grow and Bloom cannabis nutrients animated

Complete Nutrition For Cannabis Plants

Reefertilizer is the only three part cannabis grow system that includes the widest range of beneficial nutrients for your soil and your plants.
Other 3 part fertilizers kits don’t provide micronutrients (like calcium and magnesium) and neglect the beneficial microbes and bacteria living in your soil.

Don’t risk the plants you love with all purpose fertilizers. Grow better plants with Reefertilizer.

Reefertilizer’s Three Step Cannabis Grow System

Step One  Nurture a Living Soil

Reefertilizer Start being used on cannabis seedlings
Start kelp meal and mycorrhizae in scoop
Reefertilizer Start Cannabis Soil Top Dressing

Start organic kelp meal coated with mycorrhizal spores, helps soil and plants in two major ways. Kelp feeds your seedling as well as beneficial soil bacteria in the soil with amino acids and trace elements. Helpful mycorrhizal fungi maximize water and nutrient uptake allowing plant roots to establish quickly.

Step Two  Robust Growth in Veg

When your plants have 3 to 4 sets of leaves, it’s time to give them their first substantial meal with Grow. Our blend high in nitrogen encourages fast stem and leaf development. This is the step where we build up the plant structure to support heavy resinous buds later on.

Step 3  Fuel Bud and Terpene Production

Reefertilizer Bloom Nutrients for Cannabis in Flower

As plants transition to flower their nutritional needs change. Switching to Bloom provides base nutrients the plan needs to grow as well as essential nutrients for flower production. Enhanced with calcium and magnesium the Reefertilizer blend for flower will bring you bigger flowers and tastier buds.

Reefertilizer® Grow

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.

Reefertilizer Bloom Nutrients for Cannabis in Flower

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 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.

Reefertilizer Bloom combines the essential nutrients for flowering cannabis, reducing the need for additional fertilizers.

There’s Nothing Easier Than Reefertilizer

Flexible Feeding Schedule

Reefertilizer likes to keep things simple. Feed your plants once a week and top up your soil with Start once a month.

Some folks split the weekly dose and feed their plants twice a week.

If you need more or less nutrient solution, just use the same ratio no matter how much water you’re using.

If you accidentally overfeed your plants, you can easily flush your medium with water.

    Image #1 from Richard A.
  2. I have used many other awesome products however, Reefertilizer this 3 step feeding program is in a class of its own, is an absolute fail proof product… any experience level can grow amazing cannabis with ease if this is your absolute first time or you’re 100th successful time. Not to mention the customer service and the information available on how to use these products is second to none. This is an absolute must have in your growing arsenal. I can’t stress enough, it takes out all the guess work of having measuring nutrients like Cal mag, pk ,adding stackers or extra soil amendments it’s all right there in this 1-seed-2-veg-3-bloom-step program.. there’s the starter which is absolutely excellent for starting seedlings/clones and young plants and then for the veg stage there’s a veg fertilizer that does exactly what it’s supposed to do and grows amazing healthy plants and prepares them for the flowering and guess what when they get there there’s a bloom product.

    Don’t take my word or anybody elses let reefertilizer 3 step speak for itself!

Common Questions and Answers

The Reefertilizer difference

What makes Reefertilizer different from “other brands”?
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.
We designed our products to be lighter and have less packaging than our competitors. We’re happy to provide a 30-day return policy if you’re not happy with our products.

We’re not “big fertilizer”, we’re just three guys who love growing and using cannabis.

Mixing Cannabis Nutrients

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.

Organic and synthetic fertilizer

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.  

Reefertilizer® Start – Kelp Meal + Mycorrhiza

Reefertilizer Start is a soil amendment and top dressing made from organic sea kelp granules and mycorrhizal spores.

Organic sea kelp is packed with beneficial amino acids and enzymes. Mycorrhizal fungus improves the plant’s ability to absorb water and nutrients.

Reefertilizer® Grow – Water Soluble Nutrients For Plants in Veg

When your weed plants have their first 3-4 sets of leaves, you can begin feeding them Reefertilizer Grow.

High in nitrogen, our Canadian made powder fertilizer blend contains the necessary micro and macronutrients crucial for stem and leaf growth during veg.

  • Easily mixes into water for weekly feedings.
  • Chelated nutrients are immediately available to your plants. Quickly eliminating nutrient deficiencies.
  • Easy to flush accidental overfeeding.

Reefertilizer® Bloom – Powerful Flower Powder Nutrients

Switch your plants to a weekly feeding of Reefertilizer Bloom when you first see signs of flower or switch your light schedule.
With a NPK ratio perfectly balanced for flowering plants, Reefertilizer bloom will encourage flower growth and terpene (essential oil) production.

Perfect for your indoor and outdoor plants no matter their size or cultivar.

  • Enhanced with micronutrients like calcium and Magnesium.
  • Indefinite shelf life when stored correctly.
  • High phosphorus and low nitrogen ratio.

Q & A

Do you need to water until run off,? James Hayes asked on February 25, 2024

It's good practice to have a little bit of runoff. We suggest about 10% runoff every time you feed or water the plants.

I’m using Fox Farm happy frog can I use reefertilizier and when should I start applying? Joe Genter asked on November 25, 2023

Happy Frog has a lot of nutrients in the soil already but they will likely be depleted after 3 or 4 weeks of the veg period. That's when you can start feeding them Grow and transition to Bloom when they start flowering.
