Vertical Hydroponic System – What Should You Do If You Don’t Have Enough Gardening Space?

What can you do if you don’t have enough gardening space to practice your farming? This has been a challenge that has forced many gardeners to develop a vertical farming concept to solve that problem. Vertical farming involves cultivating more plants by mounding numerous layers of plant surfaces.

Vertical Hydroponic System

This concept has become the most favourable for hydroponics. Recently, the vertical hydroponic system has gained a lot of attention among urban farmers. The hydroponic farm can optimize the growth of plants, hence providing fresh produce. This method uses minimal water, transport, space and pesticides.

What is Vertical Hydroponics?

It is the setting up of a hydroponic farm in a vertical way. Gravity plays a significant role because water rich in nutrients is fed into the system from top to bottom. Therefore, you should have a variety of stacked planting levels in hydroponic vertical farming systems.

What Is Vertical Hydroponics

Vertical farming is the growing of plants without using soil in vertically heaped layers. The plants receive rich nutrients and minerals directly into the roots through the water systematically and in the correct quantities. You can grow a hydroponic plant in a vertical system using LED lights or a greenhouse using natural light.

Research studies have revealed that a hydroponic system helps in saving water for about 92 per cent. Practising indoor growing of plants reduces issues related to pests, diseases and fickle weather. This system is highly efficient in several ways because you can build, operate and maintain it at your home.

How Hydroponic Systems Work

Vertical Hydroponic Tower and Zig-Zag hydroponic system are the leading designs of the vertical farming system. These designs use the Nutrient Film Technique system (NFT) to use a constant thin water stream flowing into the plant root system. Apart from NFT, another technique that you can use is ebb and flow.

Vertical Hydroponic Tower

A hydroponic pump is used in a vertical hydroponic tower to pump the water to the top layer through a tube connected to the water reservoir. Then, the natural gravity is used to bring the water down systematically back into the reservoir, hence delivering the required nutrients to the plants.

You can also use a single tube to pump water to the top layer or several channels to various layers for optimum nutrient and water delivery. The plants are grown at an angle of 45 degrees.

Zig-Zag Hydroponic System

You can opt to use multiple pipes placed in a zig-zag pattern. House the plants in net cups at an angle of 90 degrees. This system also uses the NFT mechanism to grow plants. Nutrient-rich water is pumped into the top pipe, and it constantly flows in a stream-like manner.

Advantages of Hydroponics

Saving Gardening Space

When practising hydroponic gardening, you must optimize the limited space available. Most gardeners suffer due to a lack of enough space for their plants; therefore, the vertical hydroponic garden is the best choice for urban hydroponic farming. Hydroponic living wall systems are great for fitting into indoor rooms where they cannot use a lot of space.

This can enable using small gardening spaces, hence making it the best option for growing plants. In hydroponic farming, the roots don’t spread out, searching for nutrients; instead, they are immersed in a solution rich in nutrients.

Productivity and Efficiency

You can grow about 3 to 5 plants in space that hold one crop if you use these systems. This type of farming system ensures that your plants receive proper nutrition quantity at the correct time. It enables the crop to produce healthy leaves, foliage, stems, and fruits.

A hydroponic garden allows maximum control of light, temperature, pests and air, giving you quality output production. You can achieve maximum growth using the correct mixture of nutrient and suitable lighting. 

Easy to Maintain

You cannot experience any water run-off because of the constant circulation that occurs in hydroponic towers. Nutrients and water stay in the tube without any leakage. The water is also recycled until it expires and becomes useless. A hydroponic system is suitable for conserving the environment because water that is not evaporated into the atmosphere is absorbed in the soil. Therefore, it is straightforward to maintain just like the horizontal hydroponics.

Soil is not Needed

The common advantage in all hydroponic systems is that soil is not required for planting. Nevertheless, soilless growth is ideal for all types of hydroponics. You can minimize the infestation of diseases, weeds, and pests due to a soil-free gardening environment. This makes hydroponics a practical way of practicing gardening.

Disadvantages of Hydroponics

Definitively, no system does not have flaws. There are various challenges faced by gardeners when practising hydroponics:

Challenge of Water Flow

Delivering adequate water, nutrients, and sufficient light to plant from top to bottom is the main challenge when practising hydroponics. You should vertically deliver water because plants are put above each other. You also need powerful water pumps to send water up to the top level against the gravitational force. If you do not deliver water at the top, it collects at the bottom hence sinking the lower plants.

Insufficient Light Supply

Lighting is a significant factor in a vertical hydroponic system. You can solve light in an outdoor gardening system by systematically arranging cups with plants to access enough sunlight. Plants do not access proper light in an indoor hydroponic garden. So you must invest in electric grow lights to plant systems to thrive.

Demand more Resources

The production in the hydroponic system is very high, which requires the utilization of more resources. Unique equipment needed for the commercial vertical hydroponic systems can be costly, even though you can set it up in a budget with reduced cost.
