Crafted to Grow Great Weed

The Reefertilizer Grow and Bloom bundle has all you need to grow up to 8 plants through veg and flower.

Each bag was blended to provide the perfect balance of nutrients to help your plants thrive. Simply mix the powder into water and feed your plants once a week.

No complicated instructions or messy liquids. Reefertilizer makes growing great weed easier than ever!

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.

Reefertilizer® Grow For Plants in Veg

Reefertilizer® Bloom For Plants in Flower

Powder Fertilizers for Cannabis in Veg & Flower

Our powder fertilizers are much more concentrated than other liquid products on the market. This means a little can go a long way. They are also lighter and easier to store than liquid nutrients. Dry fertilizers also have a nearly indefinite shelf life when sealed in a cool and dry environment.

Easy, Affordable, and Safe Cannabis Nutrients

Grow and Bloom chelated synthetic nutrients mix easily into water and allow nutrients to be immediately available to the plant. They’re also easy to flush from your soil in case you accidentally added too much.
Grow and Bloom are vegan and have some of the lowest counts of heavy metals compared to other fertilizers. Beautiful clean buds? Yes Please!

A Complete Nutritional Meal For Your Pot

The large numbers on the bag shows the NPK ratio. This indicates the total percentage by weight of each macronutrient; Nitrogen, Phosphorus, and Potassium.
That’s not all that’s in the bag. Our powder cannabis fertilizers contain many micronutrients as well. Helpful stuff like Calcium and Magnesium which help with flower growth and terpene production.
What other brands do with several bottles, Reefertilizer accomplishes with just one bag.

Reefertilizer Chelated Nutrients Dissolve In Water For Quick Feeding.

How Do I Feed My Weed Plants?

You can begin feeding your plants Reefertilizer Grow once they have their first three sets of leaves. Switch to feeding plants Reefertilizer Bloom when they begin to flower.

Feed each plant enough nutrient solution to saturate the soil around the roots.

Inside each bag is a 5ml scoop to help measure out the right dose for each phase of growth.

The Reefertilizer feeding chart is incredibly easy to follow. No more mixing A and B solutions. Our nutes are the right blend for maintaining fast growth as the plant matures.

Step One
Add powder to a small glass of warm water.

Step Two
Mix until dissolved.

Step Three
Mix solution into water a your ready for feeding.

Reefertilizer Grow Vegetative Fertilizer

The Perfect Blend For Plants in Veg

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.

One weekly feeding is all your plants need to grow happy and healthy. Some folks split the recommended dose and feed twice a week.

  1. This is the easiest and best way to feed your plants, the mixture of chemicals and organic, organisms and bacteria to take care of your babies the right way , easy mixing ,easy measuring and dosage to give your plants just the right nutrients at the right time to produce amazing results
    The plants I have added have three to four more weeks of flowering yet but they look and smell amazing I started her flowering at just 6+ weeks of veg you can keep them small and start flowering with photo period strains depending upon how much room you have happy growing ?

  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!

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 a couple of 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.  

Get Even More From Your Soil Grown Plants With Reefertilizer Start

Healthy Soil = Healthy Plants

Soil health is often overlooked by many growers. If you’re growing in soil, there are millions of beneficial organisms right below the surface.

Building and feeding this subterranean ecosystem can have a huge impact on the success of your plants.

Reefertilizer Start is a combination of sea kelp and mycorrhizal spores As a monthly top dressing, it helps feed microorganisms and builds a powerful fungal network that improves water and nutrient uptake through the roots.
It’s an absolute must if you plan on growing in any soil medium.

WoW, how easy was this. 1+ tsp to 4L of water, very easy to follow instructions. No running around looking for a teaspoon measure, there's one in the Reefertilizer bag.Two "Eleven Roses" cannabis plants were planted outdoors in 10 gallon fabric bags with a mixture of store soils and worm castings. The plants loved the Reefertilizer, you could almost see them growing, looking bigger every time you looked at them after the applications.Reefertilizer was chosen for a few reasons. I needed nutes for both VEG and FLOWER, they had both.I wanted nutrients that could be easily taken in by the roots. Water soluble is perfect and Reefertilizer dissolves in water. Brilliant.I was also looking for a product with high nutrient levels but not the most extreme levels on the market for fear of burning the plants. Again Reefertilizer fit the bill with solid med/high nute levels. Throughout the entire grow the tips of the leaves never showed signs of any burning whatsoever. Spectacular.And the last reason I purchased Reefertilizer, It's Canadian. Need I say more.In the end my results with Reefertilizer proved to be outstanding with fat tasty buds proliferating each of the cannabis plants.Last year a mere 4 oz was harvested. This year after using Reefertilizer, when all is said and done its looking like about 15 Oz.Reefertilizer proved to be an exceptional product. Never have my plants looked so good in terms of health, growth and bud size.Would I buy Reefertilizer again, Yes, Yes, Yes, and I recommend it to everyone who wants to grow the best fat sticky buds in town with hardly any effort feeding them.Reefertilizer gets 5 buds out of 5 buds.

Ok so I've decided to give this stuff a go. I had a friend put a Fruity Pebble's OG in his backyard for me, and he knows nothing about growing. Needed a simple way to get the nutrients into the plant, so I ordered the Grow and Bloom. Unfortunately he had to move so I took it back home and put her on the back balcony. Side by side to the other girl I had out there, well the one I was giving Floranova compared to the one getting Reefertilizer witch is 6 weeks younger, but 3 feet taller and 4x thicker stem at the bottom. On my indoor girls, it is the best nutrients and easiest I ever tried. Will update with pictures soon. First picture is the outdoor and the other one is the indoor. Picture 3 is a Fruity Pebble's 2.0 and the 4th is a Blueberry AK-47.

I start my plants indoors around the last 2wks of March, by the time May 24 weekend comes my plants are already almost 2'tall. Love the fertilizer, the photo of my plants does them no justice and this photo is earlier. I cloned for the first time this year, I cut them May 27/21. They are about 3'tall, and I had to wait 2 to 3 wks for roots to form, so I am still impressed with your fertilizer. My 3 main plants ( the mothers) They reached close to 6' tall in the pots. Topped them 2x this this year. Humidity and Heat in Ontario this year was really bad, water issues, white mold, catapilers this year didn't have last year. But still trying to keep them going, they are root bound so watering is harder now. My plants end early because I start them early, I get to miss more rain and problems that come in the end of September and October. If you haven't tried Reefertilizer yet, you don't know what your missing. Try it. This is only my 2nd year growing and everyone is amazed and so impressed with my plants, as well as me, good luck to everyone, high52all.

I'm very happy with the product. Easy to follow instructions , Good results and fairly priced . I'm new to growing since it became legal in Canada but reefertilizer has made it so much easier and took out alot of the guessing with their products .

I am extremely disappointed in your product. I added your nutrients at the recommended dose for young plants and all I get is nutrient burn. PH is correct, in at 6.2 and runoff at 6.3. I have 3 unopened bags 1 grow and 2 bloom, I sent an email to Mike over a week ago and got no response. Guess your customer service is as good as your product... I belong to 2 Cannibis growing forums and will be sharing my findings with the groups.....

First time grower. I'm using a tent with Promix HP. I am growing both photo and auto plants and both are healthy and thriving. My photo has recently started flowering and I moved to the Bloom immediate effect. My buddy next door had a few outdoor plants and was complaining about spots and such on his leaves. I let use the Grow stuff and the effects were immediate with most of the abnormalities disappearing along with a dramatic growth spurt. The price is great considering how little (3 tsp/4l) is required for a once a week feeding.

I finally grew plants to be proud of! Super easy feed schedule with the right balance of nutrients. You can't screw up. Here are my AK47 auto flowers at 13 weeks. I grew them in pro mix, which is a pretty neutral grow medium. I snuck in a couple extra bloom feeds with great success.

Very happy with the product so far ... First time using powder nutrients and haven't had a chance to use the bloom nutes yet. The grow nutes however have noticeably been very well received by the plants and have no issues with nutrient burn.Will definitely purchase again!

This is my first time using Reefertilizer in many years of growing and there are as many BEST fertilizer to bye as there are many strains of seeds to buy i have used different types of fertilizer over the years always growing 2 plants so i won't know until harvest time on a rating i will also (for fun) with my growing friends have a miniature cannabis cup every october and this test will be more accurate.

  1. This was my second season growing with Reefertilizer Grow and Bloom. Last year’s yield was outstanding and this year’s was even better. It’s a perfect combo for a small crops (I do 8 plants grown outdoors in 5 gallon pots). Can’t wait for spring!!

  3. WoW, how easy was this. 1+ tsp to 4L of water, very easy to follow instructions. No running around looking for a teaspoon measure, there’s one in the Reefertilizer bag.

    Two “Eleven Roses” cannabis plants were planted outdoors in 10 gallon fabric bags with a mixture of store soils and worm castings. The plants loved the Reefertilizer, you could almost see them growing, looking bigger every time you looked at them after the applications.

    Reefertilizer was chosen for a few reasons. I needed nutes for both VEG and FLOWER, they had both.

    I wanted nutrients that could be easily taken in by the roots. Water soluble is perfect and Reefertilizer dissolves in water. Brilliant.

    I was also looking for a product with high nutrient levels but not the most extreme levels on the market for fear of burning the plants. Again Reefertilizer fit the bill with solid med/high nute levels. Throughout the entire grow the tips of the leaves never showed signs of any burning whatsoever. Spectacular.

    And the last reason I purchased Reefertilizer, It’s Canadian. Need I say more.

    In the end my results with Reefertilizer proved to be outstanding with fat tasty buds proliferating each of the cannabis plants.

    Last year a mere 4 oz was harvested. This year after using Reefertilizer, when all is said and done its looking like about 15 Oz.

    Reefertilizer proved to be an exceptional product. Never have my plants looked so good in terms of health, growth and bud size.

    Would I buy Reefertilizer again, Yes, Yes, Yes, and I recommend it to everyone who wants to grow the best fat sticky buds in town with hardly any effort feeding them.

    Reefertilizer gets 5 buds out of 5 buds.

  5. Some of the best fertilizers I have ever used. Plants grew so much better than they ever have! I will continue to purchase and use these wonderful products from Reefertilizer!

Q & A

After the first 4 feeding of refer fertilizer do I use plain water until flowering stage? John asked on March 8, 2024

You can continue feeding your plants Grow the same amounts as week 4 for as long as you keep your plants in veg. When you go to flower you will switch to using only Bloom.
