Hydroponics means the growing of plants without any soil. The soil can be replaced with many other materials, including water or sand. This guide to hydroponics explains the basics of this gardening method and its main benefits.
A Short Guide to Hydroponics
Hydroponic gardeners believe that it is better for a plant to grow in a medium that does not supply its own nutrition to the plant, like soil does. Several different materials can be used instead of soil, including rock wool, sand and gravel. One of the most common systems is the nutrient film technique that grows plants over water so that their roots are suspended into water.
Hydroponics believes that for a plant to be healthy it should be given the right types and the right amounts of nutrients at exactly the right time: when it needs them the most. This is easier if the plant is growing in a medium that does not supply it with other nutrient types. To make sure the plant gets all the necessary nutrients in the right format, a nutrient solution is made with a fertilizer and water, and the solution is then pH adjusted. Having the right pH is believed to be very important for a plant’s health. If the pH changes too much too often, the plant’s ability to absorb nutrients can be affected.
The solution is delivered right to the plant’s roots so that it can absorb everything it needs directly and as fast as possible. This method of delivering nutrients makes it possible to control what types of nutrition the plant gets and when it gets it. The amount of nutrients in the solution can be changed depending on the plant’s needs and its changing circumstances. Some gardeners use timers that administer the solution at what is thought to be exactly the right time.
The Benefits of Hydroponic Gardening
The fertilizer usually contains potassium, phosphorus and nitrogen, and many trace elements. The amounts of nutrients and minerals in a hydroponic supplement are higher than in fertilizers made for soil. The micro-nutrients are beneficial for plants’ health and they also help them to grow faster and better. These micro-nutrients include iron, calcium, copper, magnesium and zinc. Plants that do not get enough of these important nutrients can suffer from bacterial or fungal diseases or may be more vulnerable to pests. A hydroponic fertilizing solution also contains fewer impurities, and its purity combined with the rich nutrition makes the solution easy to absorb. The nutrients are also added in a form that makes them ready for the plant to use immediately.
When a plant grows in soil, it has to use its roots to find the necessary nutrients from the soil and then extract what it needs. Hydroponic enthusiasts believe that this process is a waste of energy for the plant and that it would be better for plants to use the energy to grow and to produce flowers. Enthusiasts also believe that this method boosts the plant’s growth rate and also encourages higher yields. Better yields could have a beneficial effect on global food production.
An Easy Guide to Hydroponics
Hydroponic gardening is not difficult and it does not have to be complicated. The easiest way to start is to try growing plants in a bucket of water or a pot filled with inert material, such as gravel or sand. If you want to explore these techniques and their theory and practice further, it is a good idea to get a step-by-step guide to hydroponics. Many enthusiasts use a system of timers, lights and pumps for watering the plants.
