The Easiest Way To Grow Great Plants

How to use Reefertilizer Start Grow and Bloom cannabis nutrients animated

Complete Nutrition For Plants

Reefertilizer is the only three part 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 Grow System

Step One  Nurture a Living Soil

Reefertilizer Start Soil Conditioner

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.

A Simple Three Step Grow System

Step One
Reefertilizer® Start – Kelp Meal + Mycorrhiza

Reefertilizer Start feeds beneficial microorganisms in your soil and builds and symbiotic mycorrhizal network that improves water and nutrient uptake. Healthy soil gives your plants the right environment for optimum growth.

Add 3 scoops before transplanting and use Start as a top dressing once a month.

  • Use with soil or coco mediums.
  • Build and maintain a healthy living soil environment.
  • Contains helpful trace elements, amino acids, and enzymes.

Add Before Transplanting
Mycorrhiza grows best when in direct contact with root systems. This friendly fungus protects roots and improves water and nutrient uptake.

Monthly Top Dressing

Kelp meal as a top monthly top dressing nourishes beneficial bacteria in your soil.

COA (Certificate of Analysis)

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.

Mycorrhizae

Mycorrhizae is a fantastic fungus grows symbiotically with all sorts of plants. When these spores are close to the roots they begin to grow. Slowly a fungal structure grows that will protect roots from drought while improving nutrient and water uptake.

Brown Sea Kelp

Sea Kelp isn’t high in any particular NPK but it’s packed with micronutrients, enzymes, and amino acids. Organic sea kelp will feed microbes in your soil. Happy microbes create an ideal environment for nutrient availability.

Step Two
Reefertilizer® Grow – Water Soluble Nutrients For Plants in Veg

When your 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.

Fool Proof Feeding

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.

There’s no need for additional fertilizers since this is an all in one powder. Ditch those messy liquid nutrients and dirty droppers.

Don’t risk your high value plants with all purpose fertilizers and save money compared to over complicated liquid nutrients.

Reefertilizer is the easiest and most effective feeding system.

Easy Weekly Feeding For Plants in Veg

Step Three
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.

Keeping It Simple

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 growth spurt, your 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 plants so you won’t need additional fertilizers.

Easy Weekly Feeding For Plants in Flower

Measure
Add the necessary amount of Bloom to a small glass of warm water.

Mix
Mix Bloom into the water until dissolved.

Feed
Mix solution into water for feeding or reservoir.

Reefertilizer Bloom Flowering Fertilizer

The Perfect Blend For Plants in Flower

Reefertilizer Bloom contains the essential nutrients required for bud growth. Added micronutrients such as Calcium and Magnesium help encourage rich terpene production.
Additional nutrients are rarely needed when using Reefertilizer Bloom. This one fertilizer blend for flower is all you will need.

Feed your plants once a week to fuel the growth of bigger tastier buds.
If you accidently overfeed, no worries! Reefertilizer is easily flush from your soil with some extra water. These are fool proof nutrients for amazing harvests every time.

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 crops. 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 amazing plants.

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.
