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.
Mycorrhizae
This 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
Not high in NPK but 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.

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 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.

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.

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 grow and I don’t have a lot of experience with nutrients, Have to say Referrilizer made it very easy and the nutrients have done amazing for the plants.
It’s my first time growing,I’m in the grow phase right now and using as directed and everything is going great. Got some great baby buds beginning and I’m getting psyched! I cant wait to get far far away from dispensary weed.
I dont know why I haven’t heard of this company sooner!!
