Choosing The Right Cannabis Grow Medium

If you want higher yielding plants, one thing often overlooked is the type and quality of your grow medium. Choosing the right type of grow medium can have a huge effect on the health of your plants and their yields. In this article we are going to go over some great grow medium options that are both cost effective, and work very well for all plat types.

Coco Coir

Coco coir is a very common type of grow medium used for multiple types of growing applications. Coco coir is an organic and inert grow medium that is created from coconut husks. The ground coconut husks is great at retaining the perfect amount of moisture and can be used to grow establish plants, plants from cutting, and plants from seeds.

Coco coir can be used for hydroponics but is not the best option as the small fibers can clog your pumps. Coco coir is best suited for standard soil planting. What we recommend is planting your plants within the coco coir and then placing it within a well-draining soil and perlite mixture.

Rockwool

Rockwool has become more widely used over the past few years, and is an amazing grow medium that can be used for hydroponic growing and soil growing methods. Rockwool is made from rock. More specifically, Rockwool is made by taking molten silica based rock and spinning it. This is a rock version of cotton candy.

Rockwool is great because it is inert, it is strong, and it is very porous. These are all characteristics that you want in a great grow medium.

Rockwool comes in a variety of sizes and is reality cheap to purchase. Most growers will use the 1 inch Rockwool cubes for starting seeds, and larger cubes for cuttings and transplants.

Unlike coco coir, Rockwool can be used in hydroponic grow setups without the worry of damaging your pumps. Rockwool is best suited for flood and drain and drip hydroponics.

Expanded Clay

Expanded clay is another popular grow medium. This is very popular and can be used to grow almost anything. Expanded clay grow medium is comprised of small clay balls/pebbles that have been fired up in a kiln. The end result is a porous and light weight ball that sums up to be a great grow medium.

Expanded clay is best suited for use in expandable drip systems and deep water hydroponic systems. A great characteristic of expanded clay is that it is inert, and pH neutral. Expandable clay pellets can also be used in tandem with traditional soil growing methods. If you are growing in soil pots, simply cover the top of the pot with expanded clay pellets. The clay pellets will help retain moisture in the soil and prevent unnecessary water evaporation.
