Growing Mediums are used in hydroponic gardening instead of soil. A good hydroponic medium will be sterile, retain moisture, provide support for the plants, be inert (won’t break down), be of neutral pH and contain nothing that can be taken up by the plants. There are various types available, each with it’s own characteristics. Some plants may be more suited to one medium than another.

Perlite is a heat expanded, man made product that is perfect for use as a hydroponic growing medium. Perlite retains enough moisture for it to be suitable as a hand watered medium, but also has sufficient drainage to be used in a recycling drip irrigation system. Perlite is extremely lightweight and is suitable for use in a variety of growing containers eg, pots, trays etc. Perlite has sufficient water absorbency for it to be used in bottom fed auto watering systems. |

Vermiculite is another heat expanded man made product which has very high water retention which is often used as a soil conditioner or for covering seed raising mixes. Vermiculite holds too much water to be useful as a medium by itself, but can be mixed with other growing mediums to improve the water retention allowing a larger period between waterings. |
