Hydroponics is the process of growing plants without soil. Both the commercial and hobby grower use hydroponic growing systems, hydroponic growing media, indoor grow lights and hydroponic nutrients to benefit from:

Year round gardening
You're not restricted to environmental changes. Plants can be grown anytime, anywhere.

Quicker plant growth with increased yield
By using a hydroponic growing system and hydroponic nutrients, you can grow your plants up to four times faster than you could in soil. Yields can also be four times greater.

Better use of space
You can grow more plants per given area than in soil, which only helps to reduce the cost of production. In fact, many hydroponic gardeners choose to grow in small cupboards or grow tents.

Enhanced flavour of crops
Hydroponically grown fruit and vegetables can taste far better than those found in the supermarket.

No soil borne pests
The need for toxic and expensive pesticides is diminished. Your food can actually be more natural than when it's grown in soil!

Healthy eating
Growing your own fruit and vegetables means you're more likely to eat the recommended 5 portions a day.

No more digging and weeding
You get all of the above with little effort.

An efficient use of water
A recirculating hydroponic system allows you to conserve water by up to 90%. As the world's water supplies become increasingly scarce, hydroponics can only become even more important.
