Easy Weekly 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 over feed your plants, you can easily flush your medium with water.

Feed Your Plant and Your Soil

Reefertilizer Start organic sea kelp feeds beneficial microbes in your soil. Mycorrhizal spores help grow fungal systems that increase water and nutrient uptake.

Reefertilizer Grow and Bloom are synthetic chelated fertilizers. Their nutritional elements are immediately available to plants once mixed into water. They speed up growth and stop deficiencies fast.

When all three parts of the Reefertilizer grow kit are used together you can greatly improve your plant’s growth rate.

Reefertilizer® Start

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.

Not to be used with hydroponic systems, but works great with coco coir and soil.

mycorrhiza

Mycorrhizae

This 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.

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.

These essential elements and added micronutrients help fuel many cell functions crucial to photosynthesis and cellular replication.

Reefertilizer® Bloom

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.

  1. 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!

  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.

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.

  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
