Hydroponics Systems

So you have decided to try growing plants using a hydroponics system instead of soil. Great! But how do you get started? One of the key advantages of hydroponics is that the gardener is in total control of every aspect of the growing environment. As such, the success of your crops will depend on the growing conditions you provide.  Give them the proper lighting, water, nutrients, oxygen, feeding schedule, etc, and plants can grow really fast, very large (to their full genetic potential), and yields can be much higher than traditional soil gardening.

What is a Hydroponics System?

One of the most important considerations a grower will make is which hydroponics system you will use. While hydroponics is the method of growing plants using only water and nutrients instead of soil, a hydroponics system is the hydroponics technique you use to grow your plants. Each technique works a little differently – most use growing medium, some use pumps and timers, and certain hydroponics systems are better suited for particular gardening applications and crop varieties than others. With that said, lets summarize the 6 main hydroponic systems, how each works, and reviews of hydroponics kits for each different system. Then we will conclude with a few helpful growing tips to get you started with your hydroponics garden.

Aeroponics – Hydroponics System

Aeroponics is a hydroponics system where the roots of a plant are suspended in an air chamber (or growth chamber), and periodically misted with a nutrient solution.  This hydroponic method is unique in that it requires no grow medium, allowing for superior aeration of the root system.

There are a wide range of options available to hydroponic growers using Aeroponics. Some Aeroponic systems are very basic and easy to operate, right out of the box.   Other Aeroponic systems are a bit more complex and often employ pumps and timing features. These more elaborate hydroponic systems are better-suited for people wishing to grow larger and more diverse plant varieties.

Advantages of using Aeroponic hydroponics systems

  • Excellent aeration of roots (constant high oxygen levels)
  • Fast plant growth
  • No grow medium required
  • Easy system to maintain, and space-saving
  • Less water and nutrients are used

Disadvantages of using Aeroponic hydroponics systems

  • Cleaning of root chamber required
  • Dependent on system to function properly (any problem with pump, etc. may harm plants)
  • Administering of the proper nutrients at the correct time is crucial to plant health

Deepwater Culture (DWC) – Hydroponics System

One of the simplest methods of hydroponic growing involves the use of a Deepwater Culture (DWC) hydroponics system. Often referred to as “the reservoir method,” this technique involves suspending the plant roots in oxygenated, nutrient-rich water. Air pumps (or air stones) are used to oxygenate the nutrient solution, which helps to prevents the roots from drowning. Most Deep Water Culture hydroponic systems use plastic buckets as a base, and suspend net pots within the buckets to hold each plant.

Advantages of using Deep Water Culture hydroponics systems

  • Easy to step up and operate
  • Plants grow fast because roots receive a high amount of oxygen
  • No drip or spray emitted to clog the system
  • Works well for organic hydroponics because no drip or spray emitters are used (organic nutrient solutions tend to clog drip/spray systems)
  • Uses less water and nutrients

 

Disadvantages of using Deep Water Culture hydroponics systems

  • Algae can grow in buckets, so it is important to keep light from penetrating the system
  • Water temperature should remain under 70 degrees (water chillers can be used, if needed)
  • Air pump malfunction can result in rapid decline of plant

Drip System – Hydroponics System

The Drip System is commonly used as a hydroponics system, both in commercial and home growing. The concept is simple: a slow feed of nutrient solution is dripped on to the roots or grow medium, slowly and continually supplying a plant with the health and moisture it needs. Recirculating drip systems reuse and circulate the nutrient solution back to the reservoir. This ensures that the roots stay moist and healthy enough, but without flooding the grow medium, as is done in some other hydroponic systems. Because the nutrient solution is constantly recycled in drip systems, pH levels may change with this re-circulation. It is important to monitor these levels to maintain a consistent and healthy pH. To prevent roots from drying out or becoming over-saturated, slower drip systems should utilized a slow drain grow medium (such as rockwool or coconut coir), whereas faster drip systems may benefit from quick-drying hydroponic grow mediums (such as clay pebbles or growstones).

Advantages of using Drip Systems

  • Easy to set up and control, with only a few part/components
  • Less wasteful due to recycling of water and nutrients
  • Works well growing plant which are constantly hungry for water
  • Drip systems are available to suite all hydroponic growers, from beginner to advanced

 

Disadvantages of using Drip Systems

  • Drip lines and emitters are susceptible to clogging from nutrient, sediment or algae build-up
  • Pump can malfunction, causing plants to suffer
  • pH level may become unstable due to recycling of water/nutrients, thus monitoring and adjusting is advised

Ebb and Flow (Flood and Drain) – Hydroponics System

The hydroponics system known as Ebb & Flow (also called “Flood and Drain”) works by flooding nutrient solution into the growing area at specific times. Once flooded, the nutrient solution then drains slowly back into the reservoir to be reused. This process repeats itself with the help of a pump and timer, ensuring the plants receive optimal moisture and nutrients. Since many varieties of plants require periods of dryness (which aids in root expansion), the method of ebb and flow is quite an effective and popular hydroponic system.

Advantages of using Ebb and Flow hydroponics systems

  • Fast growth
  • Easy to set up and maintain
  • Ideal for plants which thrive in cycles of dry conditions followed by high water exposure
  • Flooding allows for high nutrient uptake
  • Recycling of nutrients and water allows for less waste
  • Very popular for use in Aquaponic growing systems and kits

 

Disadvantages of using Ebb and Flow hydroponics systems

  • Certain plants have a low tolerance to water exposure (like strawberries), so this system may not be the best choice for growing some particular plants
  • Systems with pumps are susceptible to malfunctions and clogging issues
  • Recycling of nutrient solution may cause unstable pH, so monitoring and adjusting are advised

Nutrient Film Technique (NFT) – Hydroponics System

Nutrient Film Technique (NFT) is a hydroponics system wherein a continuous, shallow stream of nutrient solution is re-circulated over the bare roots of plants. A tilted, watertight gully (channel) is used, enabling a downward gravitational flow of nutrient solution over the roots. No grow medium is required with the use of NFT, and only the tip of the roots ever touch the nutrient solution. This allows plants to receive high levels of oxygen. The main objective of using the Nutrient Film Technique in hydroponics is to achieve a fast growth rate in a limited space. Larger and fruiting plants may not have adequate room for root growth using this hydroponic system, but for many, Nutrient Film Technique is an efficient method of starting plants and growing smaller plants hydroponically.

Advantages of using Nutrient Film Technique (NFT) hydroponics systems

  • High oxygenation of plant roots creates fast plant growth
  • Continuous circulation and aeration of nutrient solution within channels makes for an easy system to maintain
  • Conserves water and nutrients by recycling within the system
  • No grow medium required

 

Disadvantages of using Nutrient Film Technique (NFT) hydroponics systems

  • Continual delivery of moisture is beneficial in early, vegetative growth, but not ideal for flowering and fruiting growth stages of plants
  • Limited space within NFT systems for root mass, limiting size of plant grown using this method

Wick – Hydroponics System

The wick system is the most simplistic and lowest cost method within the realm of hydroponics.  There are very few moving parts to a basic wicking system: no pumps, timer, or electricity are utilized.  Instead, most wicking systems employ some sort of nylon, cotton, or other fibrous rope material to act as the agent which draws nutrient solution to the roots of a plant. Like other hydroponic systems, a grow medium helps to support the plant, aiding in moisture and nutrient retention, as well as aeration to the root zone. A plant grown using the wick system may benefit from grow mediums which drain well (perlite and vermiculite, in particular) instead of those which absorb too much nutrient solution (like coconut fiber or rockwool).

Advantages to using a wick system 

  • Simplest of all hydroponic systems, so, like the Aerogarden, a good choice for the tepid novice
  • Inexpensive, not many moving parts and limited assembly
  • No pumps or timers, and no plumbing to clog
  • Works well for growing small plants, like herbs

Disadvantages of using a wick system

  • Simple wick systems are not adequate for the larger, heavy-feeding plants grown using hydroponics
  • Size of plant is limited when using the wick system because less water is available to the roots
  • Uneven absorption of water and nutrients
  • Susceptible to toxic build-up of mineral salts in the grow medium, so occasional flushing of medium (with water) is recommended

AeroGarden Hydroponic Systems (Great for Beginners)

The Micracle Gro AeroGarden – a commercial brand of grow systems – make a great entry point into the world of hydroponics. These compact hydroponic systems come with grow lights and all the supplies you will need to start growing your indoor garden in no time.

As far as which category of hydroponics system the AeroGarden fits under, there really isnt a clear answer. The company itself notes a specific Aeroponic technology called Ein Gedi Aeroponics, in which plant roots are grown outward into air space, and then downward into a highly oxygenated nutrient solution. Ein Gedi Aeroponics has an advantage over traditional Aeroponics (bare-root spraying/misting) because plants with their roots submerged have the ability to survive for days or weeks in the event of a power outage. However – looking closely at how the AeroGarden functions – you will notice that the AeroGarden resembles more of a hybrid Drip System/DWC hydroponic system than Aeroponics. This is because it uses a pump to bring the nutrient rich water up to the plants, then drips the nutrient solution onto the grow media, and then trickles the solution back to the water reservoir to be re-pumped again (much like a Drip System). When the pump is idle, the plant’s roots are merely submerged in the nutrient solution in a similar fashion to how Deep Water Culture works.

However you want to categorize the AeroGarden, this hydroponic growing system is an effective and easy way to grow different types of hydroponic plants. As such, we recommend the AeroGarden to hydroponic beginners.

Advantages to using a AeroGarden hydroponic growing system 

  • The AeroGarden is a good choice for beginners
  • Includes everything you will need – reservoir, pump, grow light, seed pod kits (seeds, fertilizer, grow media, grow baskets, humidity domes)
  • Control panel for automation and easy growing
  • Great for herbs, salad greens, flowers, tomatoes, peppers, or any compact plant. Also good for seed starting, seedlings, clones, and transplants

Disadvantages of using a AeroGarden hydroponic growing system

  • Height of plant is limited by grow light hood (extends up to 24″ max)
  • Width of plant is limited by spacing of the pods
  • Seed pod kits can get expensive over time

General Tips for Managing Hydroponics Systems

  • Maintain water temperature between 65 and 75 degrees (employing a water chiller or water heater can help to regulate, when necessary)
  • Check pH to maintain proper levels for growing healthy, hydroponically-grown plants
  • Guesswork is not advised when mixing nutrients, so follow the manufacturer’s instructions
  • Change nutrient solution in the reservoir when necessary (usually every two or three weeks)
  • After finishing a grow cycle, remember to drain and thoroughly clean your hydroponic system (a small amount of non-chlorine bleach works well, so long as the system is completely flushed with clean water before the next grow cycle)
  • If your hydroponic system is not self-oxygenating, consider adding an air pump or air stone to help keep your system circulating efficiently and nutrient solution well-oxygenated
