Cannabis Nutrients Simplified

Simply Grow Good Weed.
Reefertilizer was built with a post-prohibition state of mind. Cannabis should be accessible for all so we developed nutrients that are easy to use, versatile, and cheap. We provide plenty of guidance to help you through your first few grows.

Grow Greener Weed.
Gardening shouldn’t hurt the planet. This is why we chose to develop dry nutrients which are easier to ship and use less plastic packaging. They are also vegan and contain fewer heavy metals than many other non-vegan fertilizers.

Grow Better Weed.
Our three-part kit was designed to get you a nice yield every time with less work. Perfectly blended for each phase of growth and containing key micronutrients for amazing tasting and smelling plants indoors and outdoors.

A Step by Step Cannabis Grow System

Step One
Start With Good Soil

Reefertilizer Start provides beneficial microorganisms to your soil, coco, or peat moss growing mediums.

Organic kelp meal and mycorrhizal spores will help feed and grow with young cannabis roots.

Add a few scoops before transplanting and use it as a top dressing every other week.

  • Versatile as top dressing, amendment, or transplant booster
  • Rhyzoglomus Irregulares grows with and improves roots efficiency
  • Over 60 trace elements will feed the soil and the plant

Step Two
A Thriving Veg Period

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

Our Canadian made powder fertilizer is a blend of micro and macronutrients crucial for the vegetative phase of cannabis growth.

  • Easy to measure weekly feeding
  • Higher nitrogen content to aid stem and leaf growth
  • Vegan and lower carbon imprint

Step Three
Focusing on Flowers

With a NPK ratio perfect for flowering plants and fortified with calcium and magnesium;
Reefertilizer bloom will encourage bud and terpene (essential oil) production.

This is a concentrated formula and does exceptionally well with large outdoor plants.
Switch plants to a weekly feeding of Reefertilizer Bloom when you first see signs of flower.

  • Immediately available chelated nutrients
  • Powder nutrients have a longer shelf life
  • Includes step-by-step grow guide

Questions and Answers

Is this product organic or synthetic?
Reefertilizer Start is organic. It consists of brown sea kelp and mycorrhizal spores.
Reefertilizer Grow and Bloom would be considered synthetic fertilizers. Reefertilizer Grow & Bloom contains chelated nutrients; which are inorganic metal nutrients that are encased by organic molecules. They are immediately available to your plants and don’t need time to break down compared to organic fertilizers.

Will synthetic fertilizer harm microbes in my soil?
Microbes in soil feed off the same elements available through organic or synthetic nutrients. Avoiding over-fertilization and maintaining the right soil pH will keep soil microbes happy.

What makes Reefertilizer different from “other brands”?
Reefertilizer tries to simplify the growing process by providing a full range of macro and micronutrients that aid with plant specific growth. By blending these together as a water soluble powder, it will save you time and money compared to using multiple products.
Reefertilizer Start helps feed microbes in your soil and improves the efficiency of the root system. Well-fed soil biodiversity and super-charged roots mean your plants are maximizing growth and fertilizer use.
Reefertilizer Grow is high in nitrogen which helps build strong stems and leaves quickly.
Reefertilizer Bloom is low on nitrogen which is important during flowering, and it has a little extra calcium and magnesium which is a common nutrient deficiency in flowering plants.
Because Grow and Bloom are chelated nutrients, essential nutritional elements are immediately available to your plants and quickly fix nutrient deficiencies.

When do I start feeding my plants Reefertilizer?
Start can be first used when you transplant your seedling or clone to a bigger pot. Reefertilizer Start can then be used as a monthly top dressing.
When your plant has 4 to 5 sets of leaves you can begin feeding them Reefertilizer Grow weekly. Water as needed between feedings.
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.

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.

    Only grew three plans with this nutrient system. At this point they seem as good as any other nutrients I’ve used.

    So far I’ve had some bad luck with my grow and lost a number of plants so the four I have left are still small for this late in season. That being said I’m up to a feeding schedule that uses 15ml for 4 litres of the grow. I’m in a tent in my garage so the season will extend a little and I’m hoping to get into the bloom by end of August early September. My growth with the product so far is okay but I’m new and not sure what to expect. I have not used the start yet (next grow) because the girls were started before it arrived

How To Use Reefertilizer To Grow Good Weed at Home

Here’s a typical example of growing cannabis for the first time while using Reefertilizer nutrients. These are real customer photos from someone who had never grown weed before. They grew 4 plants in soil using a 4×4 grow tent with a 600 watt LED grow light.

Starting seeds in small planters filled with potting soil and Reefertilizer Start.
The seed has sprouted, this is where the fun begins!
When using Reefertilizer Start, young roots will expand quickly below the surface.
The plant was transplanted to a larger pot. Now’s the time to start using Reefertilizer Grow.
Cannabis grows quickly when the right nutrients are available.
With new growth comes new leaves to suck up more light.
When pre-flowers start to show, it’s time to switch to Reefertilizer Bloom.
Flowers begin to swell and the plant takes on its characteristic smell.
The flowers are maturing. Flush your plants with regular water for the last 2 weeks of flower.
Harvest time! Buds are cut and hung to dry.

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.

This is my first time growing cannabis. I’m following what I read on the forums and by watching YouTube videos. I purchased Reefertilizer Start, Grow, & Bloom to feed my plants. My plants are growing really well, I’m an amateur but I have professional plants. I show friends, and they always respond with a, “wow.”
