Growing plants using hydroponics suggests you are growing without dirt. It does not always mean that you are growing plants without a soil substitute.

While not purely necessary it is typically advantageous to utilize some kind of growing medium. Here's a fast run down of the kinds of media available to you when gardening without dirt.

Why Use a Growing Medium When Gardening With Hydroponics

One excellent factor to use a growing medium in your homemade hydroponics garden is to ensure that the roots of your plants are adequately provided with oxygen. In a typical yard your plants roots collect oxygen from the air caught in the soil. A growing medium offers the very same purpose for plants expanded with hydroponics. Growing media are made to trap air that can after that be processed by the plant roots.

An additional reason for making use of a growing medium is to offer a food reserve for the plants. Like air, nutrients from the feeding solution are trapped in the pores of the growing medium and are after that available to the plants if needed. This can assist to avoid plant failures.

Sorts Of Growing Media

Rockwool

Made from basalt rock and chalk Rockwool is possibly the most prominent growing medium used by hydroponics garden enthusiasts. This porous material can trap large quantities of air and water at the same time.

Perlite and Vermiculite

Perlite is a pebbly volcanic rock that offers superb drain and oygenation when used as a growing medium. Its excellent drain attributes indicates that it does not hold much water therefore is bad for capturing nutrients.

Vermiculite is a mineral that acts like a natural wick and has the ability to take in huge quantities of water.

The mix of Perlite and Vermiculite is a natural for hydroponics system: one holds air and oxygen, the other holds water and nutrients.

Coconut Fibres

Made from the external husks of coconuts this growing medium is coming to be increasingly popular with organic growers. Some hydroponics growers really feel coconut fibers transcend to Rockwool in their capacity to retain air and water.

Enhanced Clay Pellets

This medium is made from baked clay. The pellets are vary porous and keep both air and water very well. They can be reused as long as they are first disinfected.

Fish tank Gravel

A very popular growing medium is the colored crushed rock that is used in aquarium. The main reason for its appeal is expense. This crushed rock is really cheap compared to other growing media. The disadvantage is that it does not hold water, and plant nutrients extremely well whatsoever. If you select to make use of fish tank crushed rock you will certainly need a constant water supply for your plants to prevent root drying out.
