Buyer’s Guide

The term "hydroponics" is originated from Greek ύδωρ - water and πονέω - cultivate. In practice, hydroponics is the cultivation of plants in a nutrient-rich aqueous solution without the use of soil. This method allows growing fresh greens and vegetables during cold seasons at home. Besides, handling of plants can be performed in a more efficient and effective manner with less efforts and time thanks to such systems.

Five Modern Hydroponic Systems for Your Indoor Garden | Comparison and Recommendations

To begin with, I would like to clarify, once again, that hydroponics is a soilless method of plant cultivation, which has a number of advantages. Instead of soil, a planter uses a growing substrate that supports plants and assists in delivering water, fertilizers and oxygen to the roots of the plants. The most suitable substrates are chemically neutral (do not affect the acid-base balance). They have porous structure and can quickly dry out. The following materials are widely used as hydroponic media: mineral wool, perlite expanded clay, etc.

The nutrient solution contains all the chemical elements necessary for the crops. Due to the fact that roots are given plenty of access to all growing media, the plant considerably spends less vital energy to find water and nutrition, which has a positive effect on the development and growth rate of its aboveground part. This allows gardeners obtaining rich harvests in a shorter period of time.

However, plants, similarly to people, are different. Each of them, especially those belonging to different families, has their own requirements for cultivation conditions. First of all, this is due to the peculiarities of the area of ​​their natural habitat. Also, many hydroponic systems are not suitable for certain conditions. It can be explained by the fact that some of them take up a lot of space; others require complex equipment, etc.

After all, there are a vast majority of options for any given situation, which makes hydroponics a popular method of growing plants among many growers. So, let’s have an insight into them to get a clearer understanding of the main differences and peculiarities.

• Wick system – it is used for small plants with short roots; it works by means of a wick through which moisture and nutritive liquid are fed to the substrate and to the roots, accordingly from the tank; This is the simplest hydroponic system that does not require special equipment. However, this planting method is not very effective, especially when it comes to big vegetable plants. The wick system belongs to the class of passive systems, meaning that it doesn’t have moving parts.

• DWC System (Deep Water System) – it is an alternative method of growing salads, as well as other small, fast growing and moisture-loving plants. They should have an extensive root system to touch the nutrient solution. The DWC system doesn't require any serious equipment. On the contrary, it commonly consists of a supporting platform for the plants which is usually made of polystyrene foam. The latter floats directly on the surface of the nutrient solution. An air pump saturates the nutrient fluid with oxygen, which the plant absorbs through its roots in sufficient quantities. The AeroGarden Black Harvest Indoor Hydroponic Garden is one of the most outstanding options among other DWC systems available on the current market.

  This type of hydroponic systems could be a great option for getting started with hydroponics skills. However, there are many cultures that would hardly grow in such conditions. Nevertheless, if you are keen on growing big crops with this system, then additional supports or trellis will be required for their reliable fixation. Besides, persistently high levels of nutrient fluid can lead to root rot.

• EBB and flow system – the principle of this method implies that roots are not permanently in the nutrient; instead, the system first fully submerges them and into liquid and then allows it getting drained back into a tank through special holes. A pump is used for automatic supply of the solution on a scheduled basis. The availability of equipment makes this system active. In fact, it is fully automatic. 

  However, the dependence on electricity makes it vulnerable in cases of unexpected power outage. Besides, it is strongly recommended to use special substrate which perfectly retains moisture; otherwise, the culture will experience lack of it already in a few hours. And this will have an extremely negative impact on the cultivation process.

• Drip Hydroponic System – here the nutrient fluid is directly dispensed to the roots of the weeds; as the excess amount of it is sent back to the tank. With the drip system, a decent aeration occurs, which prevents development of pathogens of infectious diseases. The system is always delivered with a water pump which works in tandem with a timer. In general, this method contributes to the efficient distribution of nutritive elements for the enhanced growth of your harvest. The ATAMI WILMA 4 DRIPPER SYSTEM 11L POTS HYDROPONICS allows faster growing of various crops with its auto irrigation process.

• NFT (nutrient film technique) – this is a durable hydroponics. This technique is used for growing crops that are sloped. NFT is a popular hydroponics system, as well. It has a similar principle of work to the Ebb and Flow method. It also uses a pump to supply fertilizers, water and oxygen to the grow channel. Also this system consists of a drain pipe to recycle the excessive nutrient fluid. The difference is that in NFT the nutrient fluid is recirculating over root apexes on a constant basis by gravity. Thus, there is no need in a growing medium. As a result, the roots are not supported by the substrate, so they cannot bear high weight from a top-heavy plant. Absence of substrate allows the gardener to save money and efforts while planting new seeds. 

  Nevertheless, the main disadvantage of the system is its strong dependence on the pump. In case of its damage or power cut, the roots will dry out very quickly. This is mainly provoked by the absence of any substrate.
