With the OGS Base and Aeration Mix all you will need to do is pick a compost of your choice and combined to make your own premium soil blend!

What does each component contribute?

Peat Moss: Provides unmatched CEC, and has great air-filled porosity and water holding capacity.

Pumice: Pumice makes up the majority of the mix and provides excellent air-filled porosity to keep your soil aerobic.

Perlite: Highly porous and light weight, this adds aeration for roots to thrive, while being a quick drying component of the mixture.

Rice Hulls: Rice Hulls are a fantastic source of aeration that slowly releases Nitrogen and Silica into the soil, ultimately increasing the resilience of your plants. They will break down slowly over time.

Zeolite: Zeolite will slowly release the nutrients and water it stores over time. The open crystalline structure of Zeolite is occupied by cations and water molecules which are able to move into cavities allowing cationic exchange and reversible rehydration.
