Organic Soil Conditioner With Mycorrhizae Crafted For Cannabis
Our Reefertilizer™ Start formula contains 100% organic and natural ingredients to help promote strong and healthy root growth in clones and young seedlings.
Our soil conditioner contains two simple organic ingredients: Organic kelp granules and Mycorrizal spores.


Adding this mixture to your soil or soiless mediums will add to and feed the micro organisms living in your soil. A healthy living soil will be able to better support your plants’ ability to uptake water and nutrients.
Providing these essential elements early on will help your plants establish a strong root zone as quickly as possible.
We source the highest quality organic myco and compost from respected Canadian suppliers.


What Is Reefertilizer Start Made From?
Reefertilizer Start Cannabis Soil Conditioner Has Only Two Ingredients.
Organic Kelp Granules & Organic Mycorrizal Spores
What are kelp granules?
Our organic kelp granules are derived from the natural fermentation process of cold water brown seaweed. Brown sea kelp is a fast-growing plant and can double in size in 2 weeks. Because of its fast growth rate, it is considered a very renewable source of compost material. The plant matter is nutrient-rich and provides an amazing organic compost and is well known for its use with cannabis plants.
What are Mycorrhizal spores?
Mycorrhizae (sometimes called myco) refers to a symbiotic relationship between a fungus and a plant. This fungus grows around root systems greatly expanding their ability to absorb water and nutrients from the soil. In return, the plant will supply the fungus with sugars.
How To Use Reefertilizer Start To Get The Most Out Of Your Plants
Reefertilizer Start Cannabis Soil Conditioner Can Be Used Three Ways.
An Amendment To Starter Soil, Inoculant For Transplants, & A Top Dressing
Cannabis Starter Soil Amendment For Seeds and Clones
Our Start compost and myco mixture is designed for young seedlings and clones. We recommend this method because it gives the most benefits early on in the plant’s growth cycle.
By starting your plants off in this soil mixture, you will be speeding up root growth and providing your young plants with a small dose of organic nutrients to get them started off right.


Cannabis Root Zone Mycorrhizae Inoculant
Mycorrhizae works by growing with the root system and improving its ability to absorb water and nutrients.
By sprinkling several scoops of Start to the root zone of a transplant, you’re making sure the myco is right there to grow with the roots in the new soil.


Top Soil Dressing For Cannabis
Start can also be used as a top dressing. Sprinkle 4 scoops around the base of your plant before watering.
The organic nutrients will slowly breakdown while the mycorrhizae will move through the soil and inoculate the root system.
This option is great for people who grow autoflowering cannabis and avoid transplanting.

What makes Reefertilizer Start different than other soil conditioners?
Our products are designed for cannabis and for ease of use. Start can be added to any type of soil or soilless growing mediums making it more versatile than other products. Many premium potting soils contain small amounts of myco spread out through the medium, roots need to find their way to a myco spore before they can inoculate themselves. By using start as a starter soil, your plants’ roots are inoculated sooner, resulting in faster growth.
Give it a try yourself and see why our customers love using start with their seedlings and clones.
