Raising plants without the use of soil is called hydroponic gardening. Usually, hydroponic gardening features the use of water as a growth medium. Certainly, there are more technologically precise descriptions. But for the home gardener, that’s likely all you have to know.
Many folks may wonder how hydroponics is feasible. Many people are positive that soil is compulsory for the development of a plant. It’s a source of water, energy, support and nutrients. These are all necessary in order for the plant to thrive. However these building blocks are also available from other sources.
Plants undoubtedly need water. However they don’t need to get it from earth. You’ll find that many plants grow naturally in harsh environments like sand and gravel, or even floating atop the water.
Plants also require energy in the form of sunshine and heat. But sun warmed soil is not the sole source of energy. Natural light works directly on leaves the same way it does for plants in the earth. The critical process of photosynthesis happens even when you leave the upper part of a plant open to daylight. There are plants that don’t need any daylight at all. But they still require energy to fuel their normal growth cycles.
A lot of of the plants that interest the home gardener need some physical support. Most often, this is accomplished by planting them in the ground. This is why a plant’s roots spread out and its stem is impervious to to the wind’s power. However there are alternative options for supporting your plants. For instance, twine interwoven on a supporting frame of popsicle sticks fastened to the top of a glass will do just fine.
A healthy plant also needs adequate nutrition. Potassium, nitrogen, phosophorus and several trace elements are included in this list. In a natural environment, the plant will take in these nutrients from the earth surrounding it. But there are other methods to provide these important nutrients to your plants.
A universal way of doing this is to keep the plant’s roots covered in a water-based liquid nutrient solution. A number of hydroponic systems include a grow tent that can retain wetness. A nutrient solution is sprayed onto the roots regularly to keep them soaked. This is similar to another growing technique that doesn’t require soil, the method of aeroponics.
Hydroponics can turn out beautiful, thriving plants. There are a number of kinds of plants that are able to flourish without soil, provided that they’re maintained appropriately.
