Hydroponics is commonly referred to as "the cultivation of plants in water." However, study shows that various media can support the growth of the plant, so the definition was broadened to "the cultivation of plants without soil."



* What plants can be grown hydroponically?

Theoretically, most plants can be grown hydroponically, but in practice, some are easier to grow than others. Among the easier ones are lettuce, basil, mint, tomatoes and peppers. Plants like watermelon, squash and strawberries are harder to grow.

* What are the advantages of hydroponics?

The most apparent advantage of hydroponics is its manageability in controlling the plant-growing environment. Other benefits of hydroponics are:

- Less water used

- Lower labor costs

- No need for expensive soil fertilizer

- Certainty of plant production

* What nutrients do hydroponic plants require?

Nutrients are needed by the hydroponic plants in order to grow and promote production. Basic nutrients consist of the following:

Water - There should be an adequate amount of water for optimum growth.

Oxygen - It is necessary to bubble air around the roots of the plants to supply sufficient oxygen.

Carbon Dioxide - It is required along with hydrogen for producing carbohydrates.

Minerals - Including potassium, nitrogen, calcium, magnesium and sulphate.

All of these nutrients must be present for a hydroponic plant to grow.

* What different growing media can be used in hydroponics?

The different growing media used in hydroponics are:

Expanded Clay - enables nutrients to be controlled by the water

Rockwool - made from basalt rock

Coco Coir - made from the husk of the coconut

Perlite - very lightweight volcanic rock

Vermiculite - often referred as light pebbles

Oasis root cubes - suitable for large-scale nutrient film growers

* How much time does a hydroponic garden require?

Starting a hydroponic garden requires time commitment and dedication. It needs plenty of time if you want to make sure that the plants are in good condition at all times. At first, it will also take you longer to mix the nutrient solution. From time to time, it is necessary that you check on the pests or diseases that might attack your plants.

The time involved in setting up your own hydroponic garden also depends on how big and complex it is, as well as the type of plants you decide to grow.

* What equipment do I need to start growing hydroponic plants?

Necessary equipment should be prepared before you can start hydroponics. The equipment can be purchased at most nurseries or garden centers. You will need:

- Gallon buckets

- A small pump

- Drip emitters, hose and connectors

- Rockwool (absorbent type)

- Geolite, lava rock or stone pebbles

With this equipment, you can proceed with your hydroponics planting project.
