If you want to learn how to make an indoor hydroponic garden, you need to know the difference between an active hydroponic area and a passive one. Active hydroponic systems pass a nutrient solution over the plant roots. You will need a large sized planting medium like vermiculite, perlite and pea gravel. To make an indoor hydroponic system passively, you will be providing a system that uses a wick or capillary system to feed your plants. The wick, which works like a kerosene lamp, sucks your nutrient solution via its reservoir, to the root system of the plant. Sand, peat moss or sawdust is the usual medium for growing hydroponics passively. It is quite easy to begin. You need a lot of natural light for the best results. A greenhouse is ideal.
Hydroponically grown foods taste better and are high in nutrients. You can grow more plants in a small space than with regular gardening. If you choose your plants wisely, you can also repel pests. Citronella plants repel mosquitoes and various other pests.
Easy Hydroponics
The first thing to do when learning how to make an indoor hydroponic is to decide exactly what you want to grow. Decide how many of each plant you want. How much area will you need to grow your desired quantity of plants? Let's say you want to grow a mixture of 66 cabbages and silverbeet. This can be grown hydroponically in 5 pipes of 4 inch round and 10 feet by 6 feet wide. This means you need a 6 feet square area for growing.
Mark and space 4 inch holes for the 4 inch diameter pots you are going to use. Shade cloth is helpful for the first month and if the climate is very warm. Mix fertilizer and water to a strength of 20 to 24 CF. The resulting pH should be between 5.5 and 6.5. Rinse the seedlings to remove any dirt before planting them. Don't be too generous with nutrients. Hydroponic plants can cope with not enough nutrients but can die if you give them too much.
You can use chopped rockwool, rockwool slabs, blocks or cubes, fired clay or a mixture of fired clay and rockwool as a growing medium. Cubed chopped rockwool or fired clay are recommended but you can use any of these and expect good results.
Planting
Plant the seedlings in the hydroponic solution. You need to check the water daily if you want to successfully learn how to make an indoor hydroponic system. This is to ensure the nutrient to water ratio is right. Water evaporates which is why you have to keep an eye on it. Hydroponic gardening is not for you if you can't check it frequently.
Your hydroponic plants will grow for 3 to 5 months. You have to watch out for root rot and pests during this time. When your plants are ready, you can harvest them. It can be expensive if you want to discover how to make an indoor hydroponic system but the results are usually well worth it. For more information you might want to get a book on hydroponics or search online because there is plenty of information on how to make a hydroponic garden.
