1. Aeroponics System

Have you ever witnessed vegetables grown out of thin air? The aeroponic system we are about to discuss is pretty much that. This system nourishes the plants with nutrient-laden mist and nothing else. The roots are held in a soilless medium of growth like coco coir. Nutrient-laden water has to be periodically pumped for plants to grow.

Yes, the method is quite futuristic and hi-tech, but it has been in function for quite some time now. A pipe system sends out a pressurized solution of nutrients to plants. Roots get the solution through the nozzles of the pipe in the form of droplets. This means that the roots will receive the nutrients and the moisture, besides being able to breathe freely.

INTERESTING FACT: With aeroponics, you have to irrigate for short times but quite frequently. A cycle’s frequency depends on the climate and crop type, besides the pressure you will use in the system.

Things you need for Aeroponics

• A reservoir
• Hoses and pipes with sprayers and nozzles
• Time to set the irrigation cycles
• A durable aeroponics chamber

2. Drip Hydroponic System

One of the most active hydroponic system has to be the drip system. This one uses a pump for feeding the plants with water and nutrients regularly. You may have heard about it by the names micro-irrigation system or trickle system. This hydroponic system makes use of tiny emitters to directly sprinkle the nutrient solution onto the plants. In fact it is a boon for the big problem of aeration as it provides constant watering and nutrition with the hoses, pipes, and growing media.

You can easily understand the system working. The method is all about 2 steps, one being fetching the nutrient solution by using hoses and pipes, from a reservoir. You can send the solution to individual plants. The second step involves sprinkling the solution on a growing medium that will further let out slowly.

Are you aware? Drip system was initially used for outdoor cultivation of plants in Israel to improve water efficiency. It was later adapted for hydroponics.

Things you need

• A reservoir for mixing the nutrient solution
• A water pump attached to the hose and pipe system to irrigate every plant
• Hoses and pipes
• Growing media
• An air pump for sure
• A timer, provided you want to irrigate in cycles

3. Nutrient Film Technique

Did you face an aeration problem with any of the hydroponic system you used? The nutrient film technique or NFT will solve that problem. With NFT, you will present a thin solution film at a tank’s fairly deep bottom. As a result, roots will receive water and nutrition while the upper part gets to breathe. If you see the roots mop-pressed, then do not fret because they are meant to look like that.

The most significant technical feature of this system is that the growing tank must not be perfectly horizontal. Make sure it has a slight angle. The slight tilt of the tank will not stagnate the roots with the solution, and neither will the solution flow away too fast.

NFT system dates back to the 60s. Infact it was pioneered by Allen Cooper at the Glasshouse Crops Research institute, England.

Things you need for set up

• A growing tank that needs to be slightly inclined
• A reservoir that will provide a nutrient solution for the garden
• An air pump or air stone to be placed within a reservoir
• Pipes for bringing the water to the growth tank and then back to the reservoir
• A water pump for bringing the nutrient solution to the growth tank

4. Ebb and Flow

If you are a home gardener, the ebb and flow system is for you. With this system type, you position the plants in a spacious growing bed. This bed is packed with a growing medium like perlite or rockwool. Once you have carefully planted the plants, you will flood the grow bed with nutrient solution. This system works on the principle of regularly irrigating the roots and for shorter periods.

In the name Ebb and Flow, Ebb indicates retreating water while flow indicates retreating water. Hence the nutrient flow like the tides in sea.

Things you need for Ebb and Flow set up

• A reservoir
• A growth tank
• Reversible water pump
• Air pump to aerate the reservoir’s solution
• Pipes for leading the nutrient solution from and to the tank
• A timer to switch the pump on and off

5. Wick Hydroponic System

The most simplistic hydroponic system has to be the wick system. It requires no aerators, pumps, or electricity. Among the various kinds of hydroponics systems, this is the only passive system that can do without electricity.

Wick system gets its name as to how a candle wick draws wax or oil lamp draws fuels to light itself. In the same way, the wick system uses a capillary mechanism to feed nutrient solution to the roots.

Things you need for set up

• A reservoir
• A grow tank
• More than one wick (ropes or spongy material)
• A medium for growth (coconut coir, any inter material, or expanded clay)

6. Deep Water Culture

The DWC system works almost for all kinds of plants, but it is a blessing for large plants, especially those with big roots. In this system, the plant roots are suspended in a nutrient solution, and you directly provide the air with a diffuser or an air stone. You will have to place the plants in net pots with a medium for growth to secure them. When you make the plants sit in nutrients with unlimited oxygen being supplied, your plants attain crazy growth.

In Deep Water Culture, the roots are submerged in water 24/7.

Things you need for set up

• A grow tank
• Air pump
• Reservoir filled with nutrient solution
• A water pump

7. Kratky Method

The most rudimentary hydroponic system has to be the Kratky Method. It is quite an outdated method, and only amateurs use it. This method is a simple one that requires you to plant your plants with their aerial parts outside the solution.

Krafty method is best suitable for fast-growing plants like Lettuce, herbs and spinach. It is also suitable for tomatoes and pepper but you will need a larger container

Things you need

• Mesh pot
• A narrow-necked simple vase
• Grid
