What is Hydroponics and How Does It Work?

From my article on the history of hydroponics:​

But put, hydroponics is the practice of growing plants using merely water, nutrients, and a growing medium. The word hydroponics comes from the roots "hydro", significant water, and "ponos", meaning labor, this method of gardening does not use soil.​

Instead of soil, hydroponic gardeners utilise dissimilar types of growing media, like coconut coir, vermiculite, perlite, and more.

In a nutshell, the idea behind hydroponics is to remove as many barriers as possible between a plant's roots and the water, oxygen, and nutrients it needs to grow (and thrive).

This can be done in many unlike ways, which is why we'll look at the dissimilar types of systems you can use to grow hydroponically — but first, let's understand the benefits and downsides of growing without soil.

Benefits

The most blatant benefit of hydroponic gardening is the massively increased growth rate of most plants. It'due south not uncommon for a plant to grow at least 20% faster than soil gardening. On top of that, plants volition typically yield at least 25% more than than their soil counterparts.​

This happens considering yous're making it easier for them to get the nutrients they need to grow. When they have to struggle less to discover pockets of water or nutrition like they would in soil, they can divert that free energy to growth.

It's important to go on in mind that yous only enjoy these ​benefits if you lot ready and maintain your hydroponic garden carefully.

Downsides

The biggest downside of hydroponics is the cost of buying a system. However, information technology's my aim to teach you how to build most of these systems yourself if you want to, which can reduce the cost.

Another negative is the feel required to run a system successfully. It's not THAT hard, but it's certainly more than difficult than growing the same found in soil. This is considering you are creating an artificial environment where y'all provide the water, nutrients, light, and everything else the plant needs — which means y'all also need to monitor those inputs.

If ane of those elements is out of balance, or yous have an equipment failure like a pump dying, then your entire garden tin can be put at adventure.​

Types of Hydroponic Systems

In that location are 6 main types of hydroponic systems to choose from:

• Wick Systems
• Deep H2o Civilisation (DWC)
• Nutrient Motion picture Technique (NFT).
• Ebb and Flow (Alluvion and Drain)
• Aeroponics
• Drip Systems

Wicking Systems

A wicking organization is the nigh bones type of hydro system you tin can build. Information technology'south been used for thousands of years, though it wasn't considered a hydroponic system back so.

It's what's known every bit passive hydroponics, meaning that you lot don't need any air pumps or water pumps to use it.

Nutrients and water are moved into a plant's root zone via a wick, which is frequently something as simple as a rope or piece of felt.

One cardinal to success with a wicking system is to use a growing media that transports water and nutrients well. Good choices include coconut coir, perlite, or vermiculite.

Wick systems are expert for smaller plants that don't use up a lot of water or nutrients. Larger plants may have a hard fourth dimension getting plenty of either via a simple wick system.

Benefits of Wick Systems

• Truly "hands off" if you set it up correctly
• Fantastic for small plants, beginner gardeners, and children

Downsides of Wick Systems

• Not good for larger plants
• Wrong wick placement or material can mean death for your plants

Deep Water Culture (DWC) Systems

Deep h2o culture, which I will refer to as DWC from here on out, is hands-down the easiest type of hydro system to use.​

How a Deep Water Civilisation (DWC) system works.

In a DWC system, y'all apply a reservoir to hold a nutrient solution. The roots of your plants are suspended in that solution so they get a abiding supply of water, oxygen, and nutrients.

To oxygenate the water, you use an air pump with an air stone to pump bubbling into the nutrient solution. This prevents your roots from drowning in the water — a weird thing to think about, simply it can (and does) happen to many beginner hydroponic gardeners.

Your plants are typically housed in net pots that are placed in a foam board or into the top of the container that you're using for your reservoir. With some hydroponic growing media added into your net pots, they provide a home for the very beginning of your root system and plant stems.​​

Benefits of Deep Water Culture

• Very inexpensive and like shooting fish in a barrel to make at home
• Extremely depression-maintenance
• Recirculating, so less wasted inputs

Downsides of Deep Water Civilization

• Does not piece of work well for large plants
• Does not work well for plants with long growing menstruum

Nutrient Film Technique (NFT) Systems

The Nutrient Film Technique, which I volition refer to as NFT, is a popular commercial hydroponic system.​

The simplest way to set a NFT system.

Plants are grown in channels that have a nutrient solution pumping through them and constantly running along the bottom of the channel. When the solution reaches the end of the channel, it drops dorsum into a main reservoir and is sent back to the beginning of the system over again. This makes it a recirculating arrangement, but similar deep water civilization.

Unlike deep water culture, your plants roots are non completely submerged in a NFT arrangement — hence the "film" part of the organization's proper name.

Plants are placed in these channels using internet pots and growing medium and tin can be replaced or harvested on a one-by-one ground. ​

Benefits of Nutrient Film Technique

• Minimal growing medium needed
• Recirculating system means less waste product

Downsides of Nutrient Film Technique

• Pump failure of whatever kind tin completely ruin your crop
• Roots can become overgrown and clog the channels

Ebb and Flow / Flood and Bleed Systems

Ebb and Flow systems, which are also known by the name Alluvion and Bleed, are a less-commonly seen system. But they're notwithstanding quite effective and tin can be the all-time choice depending on your situation.

Different the previous two hydro systems we have covered, an ebb and menstruum system does non betrayal the roots of your plants to nutrient solution on a abiding ground.

Instead, you abound in a tray filled with a growing medium. The tray is "flooded" with your nutrient solution a few times per 24-hour interval, depending on factors like:

• The size of your plants
• The water requirement of your plants
• The air temperature
• Where your plants are in their growth bicycle
• …And many more

Flooding is accomplished by using a reservoir below the tray, a water pump, and a timer to schedule the flooding bike.

Afterwards the tray is flooded, gravity drains the solution back down into the reservoir, where it is existence oxygenated by an air pump and air stone. It sits there waiting for the next flood cycle, and the process goes on.

Hydroponic growers choose ebb and flow systems for their flexibility. Almost of them will fill the tray with a growing medium of their choice and too add net pots to organize their plants and command the roots a bit more.

Benefits of Ebb and Flow

• Efficient apply of water and energy
• Highly customizable to your specific needs

Downsides of Ebb and Flow

• Roots tin dry out apace if environmental weather are off or the pump or timer fails
• Uses a lot of growing medium

Aeroponics Systems

Aeroponic systems are the near "high-tech" hydroponic setups that y'all can build. Only they're not that complex in one case you sympathise how they work.​

A simple aeroponic system you can build at home.

An aeroponic organisation is similar to a NFT system in that the roots are mostly suspended in air. The divergence is that an aeroponic system achieves this by misting the root zone with a nutrient solution constantly instead of running a thin motion picture of nutrient solution along a aqueduct.

Some growers prefer to mist on a cycle like an ebb and menses arrangement, just the bike is much shorter, typically only waiting a few minutes betwixt each misting. It'southward likewise possible to mist on a continual basis and employ a finer sprayer to ensure more oxygen gets to the root zone.

Aeroponic systems have been shown to abound plants fifty-fifty quicker than some of the simpler systems like deep h2o culture, but this has not been verified to be true in all cases. If yous want to experiment with this system, you will demand specialized spray nozzles to disintegrate the nutrient solution.

Benefits of Aeroponics

• Roots often are exposed to more than oxygen than submerged-root systems

Downsides of Aeroponics

• High-pressure nozzles can fail and roots can dry out
• Not every bit inexpensive or easy to prepare up as other methods

Drip Systems

Drip systems are extremely mutual in commercial operations, but less common in recreational gardens. This is considering they're simple to operate a a large scale, simply slightly overkill for a smaller garden. Regardless, they're a not bad mode to grow hydroponically that you should consider.​

Benefits of Baste Systems

• High level of control over feeding and watering schedule
• Less likely to intermission
• Relatively cheap

Downsides of Baste Systems

• May exist overkill for a smaller garden
• Fluctuating pH and nutrient levels (if using recirculating system)
• Loftier waste (if using waste system)
