Hydroponic gardening has spiked in popularity recently mainly because the quality and productivity of hydroponically grown plants has been unmistakable. These plants grow faster and healthier than their soil-grown counterparts. This is due to the fact that they are grown in an environment where there is a virtual limitless supply of nutrients and water at their disposal.

These hydroponically grown plants, because they are not grown in soil, do not need to fight off diseases and pests which are natural in soil. Pesticides can be decreased or even eliminated.

And because the nutrients and water are delivered in just the right proportion directly to the plant's roots, they are better equipped to grow - faster, healthier, larger!

Hydroponically grown plants have the following benefits:

- They will provide high levels of nutrition

- They will be better tasting

- They will be rich in color.

In hydroponic gardening you will find that the crop's water and nutritional needs are less complicated and sometimes more effective. Just a few simple measurements and it will be evident what adjustments need to be made to the nutritional balance in the water. All the guesswork is eliminated!

Although nutrient solutions are available from local hydroponic suppliers and contain the correct proportions of essential minerals, gardeners may also make their own nutrient rich solutions. This may sometimes require quite a bit of extra work however.

When it comes to the growing medium that will provide plants their nutrition, different materials have been successfully used. Materials such as sand, porous rock, gravel, pumice, perlite, and vermiculite have all proven to be good choices. Fired clay particles can also be used. These all are capable of providing a way of getting the nutrient rich water into the plant's root system.

Also, there are various types of containers and pumping arrangements for delivering nutrient solutions to the garden and draining it back to the storage tanks for reuse.

If you're just starting out in hydroponic gardening you may be wondering which types of plants are most suitable for hydroponic gardens. The answer to this is tomatoes, peppers, lettuce, and cucumbers. There are some types of tomatoes that will continue to produce year round.

Some plants can be started from seeds and seedlings. In this case use commercially available rock wool plugs submerged in the media. These make excellent incubators for germination and seedling growth.

And since hydroponic gardens are self-contained, they can be located just about anywhere space permits. It is not unusual to find these by windows, on rooftops, or in closets.
