Whether you’re growing plants indoors in your home or you are use a greenhouse for indoor organic gardening, the process is still the same. Organic gardening goes beyond the scope of simply eliminating chemicals and other unnatural substances from the products you use to care for your plants. This involves every aspect of nourishing your plants with healthy foods as well as eliminating pests with the aid of “good” pests to get rid of the “bad” pests. It’s similar to the farmer who puts a scarecrow in the garden to repel the crows. It’s a matter of utilizing products that are on hand, and making use of our resources to combat the problems during indoor organic gardening.

With your indoor garden, it’s even more vital that you exercise indoor organic gardening techniques than with your outdoor garden. Perhaps that doesn’t sound politically correct, but in essence, you are putting your own family at risk if you use harsh chemicals on the plants you grow indoors. That doesn’t mean that you shouldn’t care just as much if you’re growing things outdoors, but outdoors, oftentimes the natural elements in the air will eliminate many of the toxins that might otherwise become a part of the plants themselves, but when you grow things indoors, you do not have the potential for that to happen. Thus, it’s more important to practice indoor organic gardening for the safety of your family and those who may enter the building where your plants are housed.

Being restricted to use of smaller areas is one of the challenges of organic gardening indoors. You, of course, want to choose plants that you are going to grow contingent upon the space you have available so that they will be able to grow properly, and you can keep them healthy for the duration of the time they must be indoors. For example, unless you have a greenhouse, you are not going to grow lettuce, potatoes, or corn because there isn’t enough room. In fact, one couldn’t even grow corn in a greenhouse, though they may attempt lettuce or potatoes if it’s a big enough building.

The two most important factors with indoor organic gardening is to be certain you have enough space for the plants you wish to grow and be more cognizant of the ingredients in the products you use, choosing elements such as other insects to control insect growth in your plants rather than chemical repellents. If you haven’t planted indoors before, make sure you know exactly what is required before you begin and have all the organic products you need closely.

It’s all about marketing. That is what local growers say about hydroponic gardening. In a time when water and fertile lands to farm are scarce, hydroponic or soilless gardening is considered as a some kind of mana from heaven. Where before farmers where completely at the mercy of the seasons, now they can grow crops throughout the year and yield good harvests no matter the season. That is most direct effect of hydroponics.

The possibility that plants could survive and grow without soil as the nutrient source was first described historically by Woodward in 1699, though the technique has been in practice since the time of the Hanging Gardens of Babylon.

However, it was only in the 1840s when the principle was applied in modern agriculture. Researchers discovered that by developing a formula containing all the essential nutrients that plants need for growth - nitrogen, phosphorous, potassium, carbon dioxide, and hydrogen dioxide (H20) - the need for soil in growing them may be completely eliminated. Adopting this idea, a number of German botanists soon developed the basic nutrient formulas and growing techniques which are in use today.

With hydroponic gardening, the growing of crops requires as little as 10% as much land as regular farming, and less than 10% as much water. And sometimes, the water used may be even dramatically lessened further if the water is re-circulated.

One key advantage of hydroponic gardening is that the produce is less affected by insects thriving in soil or diseases caused by soil microorganisms. This, of course, means that farmers are less inclined to use insecticide to keep these pests away. The overall result therefore is that you have yourself crops that do not carry traces of insecticide, and can be picked ripe just before eating so preservatives are not required.

Produce such as broccoli, cabbage, celery, chard, cucumbers, eggplant, flowers, grapes, lettuce, melons, onions, peppers, broad beans, radishes, strawberries, and tomatoes have been grown hydroponically.

Another attractive feature of hydroponic gardening is water economy. In arid areas, where precious water must be re-circulated, hydroponic systems may help improve harvest yields. A large volume of hydroponic food can be grown rapidly in a small area. In fact, it has been reported that four heads of lettuce can be raised in the same amount of space required to grown one head of field lettuce.

There are various techniques to hydroponic gardening. In water culture, the roots of the plants are held in a large waterproof tank. The plants are supported by mesh or string, and they get their food from the nutrient formula contained in the tank.

Another form of hydroponics is gravel culture. Considered a more costly system to install and maintain, gravel culture involves a waterproof bench which is filled with inert pea-sized gravel. These are used to support the roots f the plants. Then, a solution containing all the essential nutrients required by the plant is pumped into the gravel from a holding tank. When the bench is full of the solution, the pump is turned off and the solution drains back to the holding tank.

The solutions for both systems are replenished periodically. And for lighting, a number of grow light devices are available used to automate lighting for plants.
