Hydroponics is a method of growing plants without the use of soil. The plant roots are suspended in sand, gravel, water, coco peat, rockwool, or clay pellets (just to name a few), and nutrients are applied directly to the roots using a solution. Any water that is not absorbed by the roots is recycled through the system to be absorbed later.
Hydroponic Nutrients
When gardening with hydroponics, you can completely control the nutrients supplied to the root system as well as the pH level. A benefit of growing hydroponically is that the roots can easily access nutrients without having to search for them. Complete control of the pH level also allows for maximum nutrient uptake by the plant. The energy saved by bringing the nutrients directly to the roots and keeping a stable pH level results in bigger and stronger plants.
The most notable difference between growing in soil and hydroponically is that soil on its own has nutrients and microorganisms that benefit the plant. When you are feeding a plant in soil, you are supplementing the nutrients while also feeding the microorganisms. If you do not feed a plant in soil, it will still grow but will not reach its full potential.
With hydroponics, you are responsible for providing all the nutrients the plant needs to survive. If you neglect nutrients the plant needs, it will die. Consequently, quality nutrients are essential when growing with hydroponics as there is no room for error.
Looking into the different systems, mediums, and nutrients for hydroponics can be overwhelming. However, hydroponic systems allow you to produce robust, healthy, and large plants that mature quickly by providing an ideal environment. What cannot be stressed enough is that when growing hydroponically, you can’t cut corners with the quality of your system. Your equipment must run, your mediums must be supportive and clean, and your nutrients must be accurate. When you meet these requirements, gardening with hydroponics will yield incredible results.
