Hydroponics is a form of agronomy which is a way of crop production and soil management. Agronomy deals with issues including producing healthier food and managing the environmental impact of agriculture. It also deals with ways in which energy can be produced from plants. In hydroponics, plant spacing can be intensive, allowing you to grow more plants in a smaller space than soil grown produce. Hydroponic grow tents come in various sizes so can be set up almost anywhere in the home. A great advantage of the soil-less cultivation of plants is that it may potentially produce much higher crop yields, and can be used in places where gardening is not possible. Whereas hydroponics has great advantages, this method of growing requires careful consideration. Plants grown in this way require different growing methods such as containment and fertilizers. There are four common methods of hydroponic gardening. These include: Drip Method The nutrient solution is given to the plants, on a timed drip system. As the emitter is dripping it delivers fresh nutrients, water and oxygen to the plants, flushing out waste. In a drip method, the plant roots are most commonly grown in perlite, grow rocks or rock wool. Ebb and Flow This method is also referred to as flood and drain. It allows the plants to be given the same amount of nutrients at the same time. Plant pots filled with a growing medium forms the bed for the plants. The plants are flooded with the nutrient at a set time and then are allowed to drain which brings oxygen to the root base. NFT (Nutrient Film Technique) This technique allows the plants to grow in channels and the nutrient solution is pumped through for short but regular intervals allowing the roots to remain moist. This system does not require a growing medium, but needs regular flushing. Passive System This is a very low maintenance form of hydroponic gardening because it does not use pumps or timers. The roots are left in the nutrient solution taking what they require from it. Although it is a slower form of hydroponic gardening its low maintenance is ideal for many. The market for grow tents and grow lights is increasing because it allows for crops to be grown all year round and the produce will generally taste better than soil grown produce.
