Hydroponics, benefits and do it yourself

Therecultivation hydroponics is a special agronomic technique that aims atcultivate plantson liquid substrate. At first sight there is always something within everyone's reach: we have water and pots available, then the soil gets dirty and therehydroponic cultivationeliminates this problem. Nothing more wrong: thehydroponicsit is very complex and can cause you to make huge messes if you aim fordo-it-yourself!

In hydroponic cultivation nothing must be left to chance, the proportions are essential as the growth medium of the plant consists of a solution containing all the essential elements.

Hydroponic cultivation

There hydroponic cultivation it has always existed. It is not a new technique as many think: it has always been widespread in research laboratories, especially when trying to understand the effects of the lack of specific nutrients on plant growth and metabolism.

With the passage of time and with the need to intensify agricultural crops, the hydroponic cultivationit has moved on a large scale. With the spread of good practices green as the gardening and horticulture, the hydroponic cultivation it has become of collective interest so much that it reaches our homes. Therehydroponic cultivationit is widely used for grow cannabis (hopefully legally!). The hemp plant, in fact, needs special attention in our climate and for this reason ithydroponicsit eliminates many limits imposed by the classic terrain.

If you've been to the hemp festival or any center dedicated to cannabis cultivation, the merchants will have offered you a hydroponic grow kit. In fact, even Ikea now offers kits for growing particular plants at home. What the traders don't say is that the hydroponic cultivation needs more attention than the classic pot cultivation.


If hydroponic cultivation is so elaborate, then why should the food industry be better off growing tomatoes, strawberries and lettuce with thistechnique? Because it's all a question of means! You certainly don't have the means at home that they have in an intensive agriculture center!

If you want to make onehydroponics indoors, you will need specific equipment such as a tube to introduce air, dacron balls, funnels to add water and nutrients ... This is if you want to start aprofessional hydroponic cultivation. Alternatively, you can aim for simple pots that have systems that do most of the work for us. Automation, however, defaults with approximation!

In recent years the hydroponic cultivation it has been used on a large scale for the production of tomatoes, potatoes, carrots, lettuce, strawberries… but also flowers such as roses.

All nutrients are supplied at optimal levels so as to ensure maximum production, in addition, the liquid medium represents a more homogeneous culture medium than the classic soil, especially with the use of special agitators.

Hydroponics: advantages

So yes, thehydroponic cultivationit is better than traditional soil cultivation. THEadvantagesof thehydroponic cultivationare so many:

  • Crops take up less space
  • Vertical cultivation is possible
  • Less use of resources
  • Targeted use of fertilizers and nutrients
  • Greater crop yield
  • Competitive costs

Theseadvantagesresult in equipment purchase costs, but an agricultural company that should buy a plot of land, for the same area purchased, can make more with the harvest.

DIY hydroponics

Who wants to experience the hydroponic cultivationcan do this by using plexiglass containers lined with black paper to protect the roots from light and to prevent the possible genesis of algae. This strategydo-it-yourselfit is effective but not easy to apply.

Do not think that theindoor hydroponics will make things easier for you: you need to change the "culture medium " (the liquid medium) to prevent the accumulation of toxic substances or microorganisms. Beyond the plant, the roots will also go "prune " to maximize ventilation.

Another sore point, when it comes toindoor hydroponicsit will also be necessary to set up a kit of lights to allow photosynthesis and plant mass production.

In theDIY hydroponicsyou cannot underestimate the culture medium, that is, the liquid medium. The soils of Knop, Sach or more commonly that of Hoagland are generally used as nutrient solutions.

These liquid solutions contain calcium, nitrogen, potassium, sulfur, magnesium, phosphorus, iron, boron, manganese, zinc, copper and molybdenum. All nutrients in optimal proportions for plant metabolism.

Hydroponic cultivation kit

At “this Amazon page” you can find a good number ofkit for growing with the hydroponic technique at home. The pots and lights can be adapted to different plant species, from tomatoes to strawberries, from cannabis to saffron.

It is clear that with ihydroponic growing kiton the market you can grow one or two plants.

If with thedo-it-yourselfaim for something more majestic, you can aim for a system ofDIY hydroponicswhere pots are placed in suspension in a large container filled with liquid substrate. The roots are free to propagate outside the pot (which must be appropriately cut out) and invade the liquid substrate.

The container or tank is connected with an outlet pipe and an inlet pipe that fishes, with a return pump to a nutrient storage tank. The return pump must be sized and properly chosen. The outlet tube can flow into the same tank where the most concentrated nutrients will be placed. This will create a sort of balance between the exhausted water at the outlet and the water loaded with incoming nutrients.
