More Information About Reefetilizer Start Soil Conditioner

Reefertilizer Start is a versatile organic soil conditioner crafted for growing cannabis.

In can be used several ways to introduce beneficial fungi and micro-organisms to your soil. Mixed with a small amount of potting soil, it makes a fertile bed for seeds and clones.

If your plants are already established you can use Reefertilizer Start as a top dressing as well.

Mycorrhizae is a type of mushroom. It’s not the type of mushrooms you see in the grocery store, mycorrhizae grow entirely in soil.

This fungus builds a symbiotic relationship with your plants’ roots. The fungus grows around root systems and extends tiny hairs deeper into the soil. These hairs work like sponges and increase the total amount of water and nutrients a plant can use.
In return for all their help, your plant will supply them with excess carbohydrates.
The mycorrhizal species we use is Rhizophagus Irregularis. It’s most commonly used in vegetable crops like tomatoes and onions.

Water Hyacinth compost makes up the bulk of Reefertilizer Start. This water plant is considered an invasive species in many parts of the world.
On the plus side, it makes a fantastic crop fertilizer that is 100% renewable. Instead of being destroyed, the plant is being reclaimed for growing cannabis.
Water Hyacinth compost also contains many helpful micro-organisms. These microbes breakdown organic matter into food for the plant and mycorrhizae.
