Hydroponics Gardening Guide – Growing Mediums Used in Hydroponics – Soil Less Mixtures And Coconut Fiber

Soil less Mixtures

There is a great amount of soil less mixtures available, which contain different ingredients. Sphagnum moss, perlite, and vermiculite are the most widely spread hydroponics components, used in such mixtures.

Being organic, soil less growing media are usually used for container gardening wick systems or on-recovery drip systems. It is also possible to use soil less mixtures in recovery systems, however, it is necessary to remember that because of very fine particles in such mixtures, they can clog tubes, pumps and drip emitters, when used without a good filtration system. By the way, according to the urban gardeners, one can use panty hose as a filter: just fit it to the return line and to the pump inlet, and all the tiny particles will be filtered out.

Most soil less mixes form a good growing medium for multiple hydroponic and organic gardens, because they can hold water well, have great wicking action, and, at the same time, they provide a reasonable amount of air to the roots of growing plants.


Coconut Fiber

The popularity of coconut fiber as growing medium increases rapidly around the world. Being the first totally organic growing medium, providing highest performance for hydroponic systems, coconut fiber may soon become the most popular growing medium ever. It is interesting to note that coconut fiber is, actually, a waste product, which contains the powdered husks of coconuts.

In comparison to rockwool, coconut fiber is characterized with higher oxygen capacity and water retaining. These features are important advantages for hydroponic systems with intermittent watering cycles.

Coconut fiber also contains a lot of root stimulating hormones, thus offering some protection against fungus infestation and other root diseases. The mixture of 50% coconut fiber and 50% expanded clay pellets is considered to be the perfect growing medium.

However, it is necessary to underline one precaution when buying coconut fiber. Avoid purchasing a low grade coconut fiber, which is very fine grained and contains a high level of sea-salts. Such coconut fiber will have negative and disappointing effect on hydroponic system.

My name is guy. I am the founder and owner of the urbangardenershop.com.au . I fell in love with hydroponics gardening. As time went by I gathered a vast knowledge base and 2 years ago I decided to find a way to make hydroponics gardening a hobby that anyone can peruse. I added a hydroponic gardening information center to our hydroponic supplies site that offers a large range of hydroponics articles. Thank you for your interest and feel free to ask questions on hydroponics gardening in our site

Improving Garden Soil

Perfect soil

What is the function of soil in our yards and gardens? Simply put, soil provides plants with mineral nutrients, water and anchorage. The basic types of soil are clay, sand, and silt. The percentage of each determines whether you have sandy clay loam, silt, loam, etc.  There are so many variables that affect soil that your yard may have a different soil type than the one across the street.

Some soil properties that are influenced by the texture of soil include aeration, drainage, water holding capacity and temperature. For example, sandy soil has excellent aeration, warms quickly in spring and has a low water-holding capacity. The exact opposite is true for clay. It has poor aeration, warms slowly, and has high water-holding capacity.

Here are the four major components of soil:

The solid portion, or rocks and minerals Decaying organic matter, microorganisms, living or dead plants and other organic matter Liquid Soil air


Amounts of each of these components determine whether or not plants will grow and thrive in the soil. Ideal or perfect soil consists of 25% air, 25% water, 40% mineral matter and 10% organic matter. As you already know, this never happens!

However, what we do to improve our soil will affect our plants.

You can re-mineralize your soil by adding Minerals Plus or Texas Greensand. You can increase organic matter by adding a good organic compost. This also increases earthworm activity and beneficial bacterial growth.  Spray-N-Grow increases microbial activity that helps keep air and water moving in the soil. To find out more about your soil, use the Sunleaves Three Way Meter.  It allows you to test your soil for pH, nitrogen, phosphorus and potassium and will give you immediate results.

Naturally, some soil needs more work than others, but with a little work and some good organic garden products, you can pretend that your soil is perfect! All of the gardening products listed in this article can be purchased from Spray-N-Grow.  

I am a gardener who enjoys growing vegetables, herbs and flowers. I believe in using organic methods and products when gardening.
