Hydroponic cultivation comes with many environmental benefits as compared to the traditional methods of soil cultivation.
It is modern and sustainable as it reduces our carbon footprint and requires low maintenance.
Hydroponics is a kind of hydroculture, where you can grow certain plants in water with the necessary nutrients dissolved.
Sometimes the roots can just be in the water, or you might sometimes have to support the plant with some medium, say, a light gravel bed at the bottom.
The water is essentially the nutrient supplier for the healthy growth of the plant when we talk about hydroponics.
This brings us to hydroponics nutrients, which is more or less the umbrella term encompassing all sorts of nutritional supplements your hydroponic plant will need.
Of course, there is a significant difference between a soil medium for growing plants and a hydroponic medium.
The nutrients required in both of these cases are different, as are the other factors, like moisture, pH levels, and the like.
All you need to do is zero down on the perfect hydroponic nutrient for your plant, and you’re good to go!

Frequently asked questions about choosing a hydroponic nutrient solution
How can plants grow without soil?
Soil is not necessarily a prerequisite for plant growth and rooting. What really is indispensable for the growth of plants is the nutrition they receive through their roots from the soil— apart from adequate sunlight, water, necessary moisture, and brightness. When you grow hydroponics and ensure that the above criteria are fulfilled, you are giving the plant all that it needs to thrive. That is why plants can grow without soil comfortably, as long as it receives whatever it needs. The soluble minerals and nutrients in an aqueous solvent act as a base from which hydroponics can receive the necessary nutrition, so worry not!
What are the nutrients to look out for in a hydroponics solution?
There is never going to be a one-size-fits-all solution to any plant care problem. The same goes for the nutrient content of hydroponics nutrient solutions. Hydroponics has a huge range of variety, and the concentration of the necessary minerals that you must look for in a nutrient solution will also vary according to the specific plant or plant category that it is curated for. That said, here are the minerals that are essential contents of a good hydroponics nutrient solution: Nitrogen (N), Potassium (K), Phosphorus (P), Sulphur (S), Iron (Fe), Copper (Cu), Calcium (Ca), Magnesium (Mg), Zinc (Zn), Manganese (Mn), and Chlorine (Cl).
Is it possible to start seeds in a hydroponic system?
It is not just possible to start seeds in a hydroponic system; it is a great option. In fact, starting seeds in a hydroponics system might be a better alternative than popping into the local nursery and taking your pick from the limited options of seedlings available. Besides, hydroponics systems are gentler on seeds and nascent roots than a soil medium. A hydroponics system causes no trauma to the roots and minimizes the chances of plant shock when they are eventually transplanted. When you start with seeds in a hydroponics system, it reduces the chances of carrying in pests from a store-bought sapling. And you will find seeds are more cost-efficient and convenient to store.
Is it possible to transplant seeds from a hydroponic system to soil?
A mundane as it seems, it’s possible and easy to transplant seedlings or growing hydroponics to a soil medium in a pot or bed. When you start with the process, make sure that you allow the roots of the newly transplanted plant to have plenty of space to grow and breathe. The pot you plant it in should be large enough for this purpose. If you plan to move a hydroponic to a garden bed, it would still be advisable to get the plant accustomed to growing in soil for a while before taking the leap and planting it outdoors. One beneficial tip for transplanting hydroponics to soil is that you have to water it immediately after the transplanting is done. These plants are still accustomed to absorbing nutrients from an aqueous base, and inadequate water at this very delicate state can be very detrimental for the plant. Of course, you can reduce the frequency of watering the plants after some time has passed, and the plant is more or less adjusted with the soil medium.
What are the disadvantages of hydroponics culture?
While the advantages of growing plants in hydroponic systems may outweigh the disadvantages, there are a few you should be aware of. First, a hydroponics system does not come for cheap. Second, you have to be careful to avoid overdoses because hydroponics are delicate. Lastly, the soil medium is absent and direct absorption puts the plants at risk if you make some major mistakes. But, if you compare these few drawbacks up against the bunch of benefits of setting up and maintaining a hydroponics system, the former seems quite negligible.
The chemical composition and necessary ingredients are essential in picking the right hydroponics nutrient solution for your plant.
Once you are done and dusted with that part of the process, the rest of your experience with hydroponics should be relatively easy for you!
This is the cue for you to get yourself a hydroponic plant— and revel in your success as a plant parent as you watch it grow healthy and strong!
