Cannabis needs 3 things to grow:

Light, Air, and Nutrients.

The first two are easy,
nutrients should be too.

This is what Reefertilizer was made for.

Start is an organic compost containing a living fungus that will grow with, protect, and improve the root system.

It can be easily added to your soil or soilless growing mediums.

Grow and Bloom are 2 powerful fertilizers designed for the vegetative and flowering stages of cannabis growth.

Both are easy to use water soluble powders that contain the essential primary, secondary, and micro nutrients that cannabis needs to thrive.
