Growing media

What is Growing Media?
The material that your plants grow in is called the 'growing medium'. Dozens of different ingredients are used in varying combinations to create homemade or commercial growing media.


Growing Media
Instead of soil for root growth, hydroponically grown plants need a porous but stable and inert material. Different materials can work, depending on the situation.

Growing Media: Terrestrial orchids, such as paphiopedilums and some cymbidiums, grow in soil. But most tropical orchids are epiphytes, which means that they grow in the air, rather than in soil.

Growing media/growing medium A material used to culture plants.
Growing season The number of days between the average date of the last killing frost in spring and the first killing frost in fall
Growth regulator A chemical used to increase growth or shorter stems.

The growing media for the planters is a soil-less mix. Coarse gravel was layered across the bottom, followed by a finer blend. On the very top, marble-sized balls of clay were positioned, which house the bacteria that help break down the fish waste.

The only difference is that you use pond plants in a water growing media as opposed to land plants in potting soil. Even a bowl can hold a small water plant. A nice size container is 12-to-24 inches wide by 12-to-16 inches deep.

Use when placing growing media and drainage material in the container. A funnel made from paper or aluminum foil can be helpful for placing the growing media into a container with a very small opening.
Atomizer or bulb-type sprayer
Use when misting and watering the terrarium.

Most fertilizers commonly available in garden centers do not contain all of the 13 elements necessary for plant growth because the growing media usually provides many of them.

Fungus gnats are highly attracted to moist and over-moist growing media, so they are almost always concentrated where there is a bit more moisture. Over-watering is one of the most common mistakes of all gardeners, new and experienced.

The bare essentials for raising seedlings include containers, growing media, labels, and the living plant material you are going to grow from. You will also need a watering can with a range of sprinkler heads and a waterproof pen or pencil for labeling.

Minimize disease problems by using a sterile growing media such as vermiculite or a peat-based seed starting mixture.
Wet the seeding medium and allow it to drain before sowing the seeds.

This fungi overwinter in soil, and can be transmitted by seed, contaminated soil and other growing media, garden equipment, watering, plant roots, or other vegetative parts. Soil temperatures above 80 F and air temperatures above 70 F favor wilt diseases.

Some gardeners prefer soilless growing media which includes vermiculite, perlite, or peat moss, used alone or in combination. You can grow the seeds from start to finish in a sterile potting mix. Just make sure that the soil is moist before filling the containers.

sanitation The process of removing sources of plant pathogens from a growing area, for example, by cleaning up plant debris and sterilizing tools and growing media.
saprophyte An organism that obtains food from dead organic matter.

Plants grown in a hydroponic garden grow in a special soil-less media. This media can be made from rock wool, clay pellets or perlite mix. The most important job of the growing media is to allow for good drainage, yet retain moisture and air needed for growth.

Previously used containers need to be cleaned thoroughly with a disinfectant or soapy water. Use seed-starting kits or fill plastic, clay or peat containers with growing media. Desirable media is loose, fine in texture and drains well. Purchase commercial mixes or buy materials and mix yourself.

Succulents and cacti grow best in very well drained soil. Many die from root rot when soil conditions are too wet or waterlogged. Any quality commercial cactus mix will work fine as a growing media.
