The Easiest Way To Grow Great Plants

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.

Grow Easily

Reefertilizer was designed to make home cultivation easier for beginners and simpler for advanced growers. Our 3 piece kit will provide cannabis plants with their nutritional needs from seed to flower for up to 8 plants.

Grow Greener

Dry powder nutrients and fertilizers are lighter to ship and require less packaging. Reefertilizer’s trio replaces several bottles of liquid nutrients because of their concentration. Our products are vegan and contain fewer heavy metals than most other fertilizers on the market.

Grow Better

Growing quality cannabis at home shouldn’t be such a large learning curve. Our three-part kit simplifies the growing process while giving you an improved yield with less work. Our Beginner’s Guide to Cannabis Cultivation is free with each order.

Grow Like A Pro, Even When Your Not

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.

Mycorrhizal spores (Rhizoglomus irregulare) 2 spores / g

Guaranteed Analysis:
Total Nitrogen: 2%
Available Phosphate: 1%
Potassium: 2%

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 including cannabis. 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.
Mixing Reefertilizer into water for veg

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 cannabis feeding system.

Easy Weekly Feeding For Plants in Veg

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

Mix
Mix Grow into the water until dissolved.

Feed
Mix solution into water for feeding or reservoir.

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 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 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 harvest every time.

Questions and Answers

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.

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.

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.

  2. I am thrilled with these nutrients. They are easy to use and the results are great. I grew this Girl Scout Cookie Autoflower outside in 69 days – seed drop to chop. She’s curing in the jar and smells amazing. Can’t wait to see my next crop from my indoor tent using Reefertizer nutrients.

  2. Two issues- 1) The treatment rate prescribes Weekly nutrient levels with water as usual. But if water in five days then when plants need water or if you get out of sync frustrating. If nutrients used every watering harmful to plants. 2) The Bloom does not dissolve completely like the Grow. Ends up with chunks floating in the bottom of the watering bucket.
    The Start is awesome. Boosts a clone way past anything that I have found.

  3. So far has not failed me

    • Thanks for the great review Denis. If you have any issues please let us know so we can help in any way we can.

  4. Plants are large and look great, looking forward to bloom

  5. I’m so glad I came across this product. I’m new to growing and the 3 step products made it very easy to be successful. There’s a lot to worry about but it’s nice to know I’m feeding my plants properly.
