Gardening is both an art and science, encompassing plant cultivation, and ideal methods of nurturing their growth and development.
Sounds like a fantastic endeavor to take up as a hobby, right?
In this inescapable world of progress and innovation, this industry takes the cake and for a good reason.
Hydroponics systems are a mainstay in today’s modern indoor gardening systems–they allow for efficient gardening with a lot more ease and less space compared to conventional methods.
One of the most important parts of the modern gardener’s kit is the trusty hydroponics pump. With everything said so far, let’s dive in!
For those short with time, jump right ahead to:
What is an air pump
The essentials of hydroponics
The four key ingredients to your desired garden are air, sunlight, nutrients, and water.
Within traditional agriculture, the matter concerning plant oxygen intake usually presents no issue. Small fissures scatter throughout the soil and provide the plants with sufficient amounts of oxygen yet, with indoor controlled gardening, the submerged plants require, more often than not with a good quality air stone, these products provide oxygen to prevent the ecosystem from drowning within a nutrient solution.
Where are these pumps most commonly used?
The underlying goal of using hydroponics-oriented (or even those made for aquariums) air pumps is to deliver air into a designated reservoir, which will house the nutritional mixture. During that process, air stones inside the hydro tub convert the pumped air into bubbles that deliver the oxygen to the plants.
This way the nutrient solution is easy to absorb by the plants, thus ensuring the survival and flourishing of the plants.
You might wonder, why would a plant need this? Water already has oxygen in it, so why would dissolving the oxygen be a requirement?
The oxygen atoms that makeup water molecules chemically bound to those hydrogen atoms and are therefore unavailable to plants.
The fundamental idea behind hydroponic gardening revolves around placing plant roots submerged underwater from where the essential nutrients will be delivered.
Aeration of the plants
In case the water has no oxygen left, it will become stagnant, which will lead to the potential drowning of the plants and their death. Aerating the air is a top priority at all times.
This is where a hydroponic air pump comes into play. By delivering dissolved oxygen into the water, they prevent the growth of algae and different diseases that can affect your plants.
Thanks to this device, all the necessary needs of the roots (from nourishment to oxygen) are satisfied accordingly.
But that is not all! These products do a stellar job of keeping the temperature of the ecosystem consistent and almost identical to the one present in the room it is placed in.
Water pumps that are most commonly used in hydroponics usually comprise a submersible fountain and pond pumps that are widely available in a wide range of stores.
The role of an air pump extends far beyond merely preserving the life of the plants in question. It plays a vital role in absorbing hydroponic nutrients.
Some hydroponic systems, such as the deepwater culture (DWC) offer a novel approach to cultivating plants so the right choice falls upon what suits your needs the most.
With a setup air pump, air stones, and an air-line to a connection of both the air stones to the air pump you are ready to get down to working on your garden.
Do you need it for your hydroponic system
An interesting outlook towards the entirety of hydroponics is that the entirety of indoor production, with all of its benefits, is as available to you as it is to the International Space Station.
The future of this method grows brighter each year as the exclusion of pesticide usage, higher productivity, and shrinking the entire area that agricultural land uses leads to having this method available virtually anywhere!
The perfect system for a beginner
The learning curve can be steep for the duration of the learning period. It is for this reason alone that many gardeners take up hydroponics progressively, from simple to complicated systems.
It can be harsh for beginners to determine to optimize their hydroponic gardens when they are just starting out, so picking a less sophisticated system is highly advisable (more on that later on).
The variety of different methods places air pumps as either obligatory or facultative.
An example of an obligatory method would be the deep water culture. This option uses air pumps because roots are submerged in the water and they receive dissolved oxygen from the nutrient-rich water.
The relationships between oxygen and temperature
Oxygen levels are inversely proportional to temperature. At 20 degrees celsius, oxygen is around 10 ppm.
If the water gets heated because of sunlight or tropical climate, it reduces the level of oxygen availability in the water.
It plays a crucial role in sending hydroponic nutrients from the reservoir into the growth tray or flood table.
The pumpless method of hydroponic gardening
Optional usage of air pumps is also possible within methods such as the Kratky passive hydroponic technique for growing plants suspended above a reservoir of nutrient-rich water.
Because the essential attribute of this technique is the absence of circulation, it needs no additional inputs of water or nutrients after the original application, and no electricity, pumps, or water and oxygen it requires circulation systems.
If you opt for a pumpless method, it will usually work by lowering down the water level in the tank and making an air gap, allowing the plants to develop air roots that will absorb oxygen from the surrounding air in the created air gap, and the rest of the submerged roots will be used for the nutrient and water uptake.
A wide variety of pumps are available to you, but the real question is “How can I choose the right one?”
Foremost, you have the option to choose pumps specifically designed for hydroponics while the alternatives might be designed to serve their role in aquariums, yet they all do the same thing most of the time.
So, how do we differentiate between pumps when the basic functionality, providing oxygen, remains the core essential?
Air pump attributes:
Every pump has a set of specifications that set it apart from the rest. They can be classified by the following:
- Energy usage
- Ease of use
- Head Height
- Energy usage
- Air stones
- Airline tubing
- Maximum water depth
- Air volume
- Manufacturer’s warranty
The type of pump you will want to get largely depends on the conditions of the system and the environment and can be classified into the following:
- Inline model pumps
Gallons-per hour (more commonly referred to as GPH)
A general rule among gardeners when choosing the ideal pump for your garden is to calculate the gallons-per-hour (GPH). This capacity will be crucial in choosing the right pump.
GPH represents the flow rate within the units that remain contained within that flow rate. Some of them have “liters” per hour inscribed on them for easier calculations.
If, for example, your chosen product would operate within 300-500 GPH, it might mean that the devices with a dual sized adapter (two separate ones) that operate on both power levels.
Smaller ones will often a minimized GPH in a power comparison with their larger counterparts that will often give a much higher max GPH (which is why the size of the pump an important indicator of power).
An accurate formula for determining the ratio would be :
(T x 2)
The representation gives off the information of gallons you have per hour, multiplied by the number of towers times two.
The higher a pump needs to pump the water up, it will assert more pressure on itself from the weight of gravity and water.
Head Height (HH)
The “Maximum HH” is often used to describe a precise point from which back pressure (BP) exerted overreaches the capacity an individual pump can release.
What this means is that, if your device is operating within a specific height (let’s say 7-8 feet), the backpressure of equal value is given out on the device itself which will have to be overpowered before a steady flow of water is made available.
That is why, during the process of selecting an ideal product, placing a model that possesses an above-average HH is ideal (the higher the better, as it encompasses an abundant psi rating.
In case size becomes an issue, the ideal answer that would apply to most situations is to get a pump that would be slightly bigger than the calculated requirements for the designated system since the output can always be reduced while the maximum output will be limited to the product’s capacity.
When contemplating what choice to make before purchase, your primary concern ought to be the system you wish to employ, what kind of attributes are you looking for in your pump, and how easy it is to set up and maintain?
A rule of thumb regarding power measurement is around 500-600cc, which provides an ideal option for most users.
This segment of the requirements is handled rather easily, as many options you might stumble upon have the necessary or higher characteristics.
An important factor that can be essential for your choice is the system you plan to employ. As you can expect, certain pumps are designed for optimal performance in certain growing systems while others might present a detrimental barrier to success within the boundaries of an inadequate hydroponic technique.
Let’s take a look at one of the most common hydroponic systems you can come across:
Differentiating different classifications from one another
First and foremost, these systems fall into two distinctive categories: they can be either passive (where the liquid is re-used, often employed in basic methods of growing) or active (the liquid is subsequently subjected to change, more often employed in advanced commercial usage).
Active represents a system where the nutrient solution will be subjected to movement inside the tank while the passive counterparts are reliant on a wick or anchor for the growing media.
When getting a pump for yourself, especially pumps that will be working non-stop, maintenance and cleaning will be an integral part of their upkeep.
The composition: what constitutes an operational air pump
Despite all the fancy additions and capabilities of each individual product, the core of these items lies within electromagnets. The main body encases a coil that will be the main driving force, supported by impeller shafts that have a magnet itself.
As hydroponic pumps have mostly consisted of rather simple parts pieces, engaging in the maintenance process is likewise an easy endeavor, especially once it becomes a regular activity.
The parts can be disassembled and assembled with ease while the cleaning process can be done with a sponge, brush, or dish soap, preferably after every nutrient solution change.
Choosing a stagnant or active option for the desired ecosystem
Another exclusive discerning feature present within this area is the differentiation between recovery (RC) and non-recovery (NRC) options.
The main benefit of RC lies in its simplicity and lesser costs; the reusable fluids that were applied to one ecosystem can be transferred to another one.
The NRC places focus on using the solution of nutrients to their fullest extent, salvaging nothing due to the prioritization of growth of the product over the resources.
The type of pump you take will depend on the system immensely, hence they can be classified into 6 groups:
The Wick System
The original method, also the easiest and most basic system that is ideal for beginners.
This system holds the top place among options that are a breeze to maintain, it’s base function revolving around the circulation of necessary fluids that are housed within a holding unit to the designated plants.
This passive method is great for fast-growing options such as lettuce or herbs. The absence of both moving parts and the reliance on air pumps to function provides a marvelous choice for the average hydroponics enthusiast.
Even if it does not require electricity or an air pump, the inclusion of an aeration system greatly enhances its potency.
- Easy to set-up and affordable
- No complex mechanisms whatsoever
- Recirculation allows this method to be water-efficient
- Basic components include: one net pot, a holding unit (can be as simple as a mere bucket), and a pump (optional, often left out in the more basic set-up)
- It is not a good option for water-hungry plants
- Nutrient delivery is sub-par in comparison to other systems
- Functionality remains optimal as long as the grower’s production is within boundaries–small scale plant growing recommended
- A limited selection of plants flourish under this system
- Prone to toxic nutrient build-up within the growing media
Deep Water Culture (DWC)
The next step from the Wick system is the DWC. It falls into the “simple” category of hydroponics systems due to its relative ease of use and installation, which makes it great for beginners.
Plants that develop this way will be positioned in a soft holding placement, alongside a medium that will allow them to expand.
The core functionality behind this option lies behind providing the roots with a direct and stable supply of everything they need while the plants themselves are suspended above.
This system is regarded as the “purest” type of hydroponics, with gratifying results to back up the effort.
The air pump that is most commonly used in this kind of hydroponic system is similar to those found in aquariums, as a strength from 200 to 240 gallons-per-hour would accommodate most system types of this kind.
This is also the only system where an air pump is mandatory for it to function, where the alternative options utilize the airflow through which oxygen reaches the plant’s roots without the implementation of an air pump.
- Cheap and easy to set-up
- Arguably one of the quickest growth methods
- Root clogs
- Unsuitable for plants with a long growth time
- Not designed for growing big plants (although it can accommodate bigger plants than the Wick system)
- Pump daily maintenance is recommended (if it is installed)
Ebb and Flow System (EFS)
An elementary form of EFS includes all the basic components present from many other alternatives while including additional equipment to supplement precise functionality.
With a holding unit responsible for upholding both the plants and their medium of development, the fluid containers and air-providing systems can do their job without much intervention of the user.
This process is controlled by the settings of the timer, drastically lowering the possibility of the system failing due to human error in quantity or timing of nutrient delivery.
Desired liquid content levels are constant thanks to the integration of tubes that fill the role of an overflowing mechanism, ensuring quick emptying time for used liquids. The charm of this system lies in its ability to versatility and variety of plants that can be grown within it.
Determining the right pump
Determining the correct pump for this system can be tricky and, in most cases, this stage can be simplified by answering two questions:
1. How much water do I plan to use and will I want to increase the desired amount later on?
2. The HH value
The first necessary amount for the first necessity can be determined by simply filling the container with the desired water level while also keeping track of the number of gallons used if it is not already written on the container.
In the case of multiple growing chambers, multiplying the number of growing chambers by the water volume that was already tested will give off the required amount.
The second part is determined based on the correct measures for the water volume of the pump.
After doing all of the measurements, there should not be much of an issue in picking out the desired models.
- An unparalleled option for water-demanding plants
- Easy construction and maintenance
- A variety of growing medium can be applied
- Since this is a method that allows its users to freely salvage used up resources, instability in the liquid content is rather common.
- This system is somewhat susceptible to algae.
- It is almost imperative to possess an active power supply and an adequately powerful pump throughout the process.
- It requires some experience to maintain and set up the timer
- The amount of plant media is quite high
- Equipment failure can occur sometimes, causing root dryness
Nutrient Film Technique (N.F.T.)
While all hydroponic methods offer a differentiated approach towards growing plants, the NFT stands separately due to the unique characteristic of employing a constantly flowing stream of liquid to provide nutrients to the plants.
The system demands a strong and sturdy pump that will keep up with the dynamic setting of the system.
Pump strength requirements
The strength of the pump could be ideal to go from 700 gallons-per-hour (which would be a noisy option in most cases) to more silent but less powerful pumps with the power of about 320-400 GPH.
NFT methodology and variety represent a wide area that newcomers can adapt to their liking as long as one condition is fulfilled: a constant flow of water. Once that is assured, the entire process can seem like a breeze.
The importance of free flow and depth of the water
It cannot be stressed enough how much the reliability of this method hinges on the placement of pipes. Everything, from the speed of flow to the overall functionality of the entire ecosystem, will play out according to the aforementioned.
This, in most cases, is not a very deep-demanding choice, so even a mediocre amount of pumping power will be sufficient.
The most important quality regarding the speed of flow is more reliant on avoiding stagnancy then ensuring rapid, non stop circulation as stagnant fluid, which deprives the ecosystem of its essential materials rather quickly in this system, cause the most harm to the plants while even a slow flow will ensure their steady growth.
The momentum of the mechanism and its maximum extent represent two crucial factors in determining the GPH that will be pumped.
The velocity of the re-introduction of liquid is about ½ gallon and can be done within a designated timeframe (timed at the desired time) and thus can amount to an impressive quantity of water that will be reused.
- Easily maintained and set-up
- Easily maintained and set-up
- Lessened requirements for aeration due to the constant influx of liquid
- Nutrient solution recycling allows for significant water-saving
- There is no need for a growing medium for this system to function
- The air pump will have to keep on running 24/7, alongside available electricity
- Little room for error – the roots might dry very quickly in case of an air pump malfunction or power outage
- Functions optimally when the choice of plants is limited to smaller, faster-growing options.
An intermediate option, the beauty of hydroponic flexibility is exemplified in its diversity, and this method is a perfect example of that principle.
The discernable feature the drip system employs is contained within small emitters and tubes that drip nutrient-rich water onto your plants constantly, continuously flowing in this system while also having the option of non-recirculation.
A submersible air pump that can provide from 120 to 300 gallons per minute will go a long way for this option.
While picking a pump for a system as diverse and variable as the drip system it comes as a light breeze knowing that the same principle of water volume and might apply to the selection process.
Deciding the GPH tends to be more tedious yet also not as important as with other hydroponic systems because the drip system incorporates a gentle soaking of the plants which can be adjusted to last from 5 minutes, hours or 24/7 with adjustable volumes that deliver the water in appropriate quantities with the help of a timer.
Water pressure will remain a key factor in the process of consideration of the right pump. The higher the intended amount of plants and dripper devices, the water pressure will need to be higher.
- More control is given to the operator
- The system can be modified to suit the grower’s needs
- Lesser chance of equipment failure
- Lesser maintenance in the non-circulating variable
- The recirculating option requires pH and nutrient level maintenance
- The emitters and pipes and susceptible to clogging
- Care must be taken in measuring the correct amount of liquid distributed to the plant
An innovative approach, favored by seasoned growers, focuses on efficiency which improves on every aspect that the original hydroponics systems were based on.
The usage of water is only 20% compared to the other hydroponics system and the growth speed is visibly increased, making this method a prized jewel for veteran gardeners.
The aforementioned methodology can be divided into two separate categories: The classical – primordial method of providing water to the plants and the method reliant exclusively on pressure.
Levels of pressure
The classical system utilizes higher amounts of pressure ( from 60 to 90 psi in most cases) to achieve its desired effect.
Lower pressure spraying systems are ideal for a few tanks while the higher end of the spectrum is preferred in case of high-end production, similar to industry-levels of modernized agricultural production.
These ways of execution, on the other hand, are characterized by a lack of pumps due to the large number of cycles (switching the device constantly from on to off) would be detrimental to the equipment.
Instead, the abbreviation is conducted by compressing the two-sided storage unit (the purpose of said unit is to store air and necessary liquids which are both needed for operation).
With a pre-determined water alignment, stretching from the storage unit containing the mixture runs to the liquid delivering compartment of the system while the valve system is controlled with a pre-installed solenoid. The opening and closing intervals are set at a specific time that is designated by an installed timing gadget.
The counterpart, consisting of a lowered amount of pressure, usually goes with a standard submersible set of water pumps as the standard equipment set, yet requirements set a specific amount of water pressure to prevent the water trickling out of the sprinkler/mister heads.
Take note that the number of these devices you introduce into the system will accurately determine the pressure that will be required to be exerted to sustain it.
An important bit of information to remember is that the pumps which can be used under the water usually only give out GPH and head height information (and GPH is a measurement that shows the correct amount of volume).
Accessories That Go with the Air Pumps
When getting a dedicated model for yourself, the purchase is often accompanied by a selection of items that complement the desired result–a functioning hydroponic system of choice.
Nutrient solution- The bread and butter of the growing process, the solution of nutrients that will be required for an admirable garden to function will contain the following:
These essential macronutrients will be the key elements that will deliver on the promise of high-quality produce after the process of growth reaches its end, although requirements extend far beyond picking the right ingredients.
Measurements of the nutrients, the quality of water, the pH levels, and the temperature all play a vital role, and thus testing the liquid solution in a lab is a good idea before putting it to practical use in the system.
Reservoir–A backbone of every hydroponic system, this piece of equipment is important, and investing a bigger sum of money for a good one is a fantastic idea, so pick the best of the best as it allows for the free circulation of the lifeblood of the hydroponic system–the nutrient solution that allows the plants to grow.
Role of the reservoir
The reservoir is the body that contains the entire system and its functions can be summed up as the following:
- Distribution of liquid to the plants
- Preparation and storage of the nutrient solution
- Oxygenation Of Nutrient Solution
- Maintains equal concentration of the nutrient solution
- Enables monitoring and modification of pH levels of a nutrient solution
- Allows for the temperature to be monitored and maintained
The designated role of a reservoir extends to a lot more than just holding in liquid as it houses the air stone/air diffuser, the air pump, and often a lid that will prevent the outside contaminants to reach the nutrient solution, keeping it pure and of the desired quality regardless of the setting.
Determining the right side of the reservoir is dependant entirely on the scale of the planned system to uphold, so it is not uncommon to take up a slightly bigger reservoir (size can range from 10 to 200+ gallons hydroponic reservoirs).
As temperature will definitely play a big role in maintaining ideal growth conditions (too low and the plants might determine that the growing season has ended and will stop growing or if it too high, they will be unable to hold on to oxygen and the growth process will be severely hindered).
The ideal temperature in the reservoir would be between 65-75 degrees Fahrenheit which can be supplemented with a water chiller during summer months and a water heater during the winter months as both of these additions strike a perfect balance that allows for constant temperature in the tank.
Putting emphasis on maintaining the reservoir is always a top priority for ensuring the longevity of the garden. This includes changing the water completely from time to time, monitoring the pH level and PPM or EC daily, and checking if there are any physical changes in the reservoir itself.
Delivery tubes–These components are tasked with delivering liquid to the plants.
Delivery tubes are the medium that sprays the nutrient solution/water upwards to ensure that the necessary minerals go through to reach the plant’s roots in the growing chamber and then go right back to the reservoir.
The recommended material construction for these parts of the system is composed of standard PVC tubing and connectors, as well as irrigation tubes and connectors that are most commonly seen in everyday gardens.
It is also a good idea to employ drip emitters or sprayers as they offer a more controllable dispersion of liquid but are susceptible to clogging.
Air stones and air diffusers – Getting into the business of hydroponic gardening requires more than just raw pump power to deliver the necessary oxygen to the plants, and this is where these two essentials come into play.
To create a livable atmosphere from where a plethora of plants can be nurtured to the fullest extent, diffusing oxygen plays out the role of providing usable air that goes through one of these products to deliver said the air in the form of bubbles that enriches the liquid with an abundant supply of oxygen.
Air stones are produced with porous rocks that have many small holes and can be found in various shapes and sizes.
When the air is pumped into the air stone, the latter absorbs the air and then releases it, ensuring even distribution of air in the form of air bubbles.
The biggest flaws of air stones, however, are that they get used up pretty quickly, and clogging, alongside developing a film build-up is not a rarity, which can seriously affect the performance and growth of the plants in the system.
They are not expensive nor hard to upkeep. On top of that, they are easy to find in most stores (including pet stores).
Air diffusers have the same purpose, yet are a different cadre altogether.
They are often made out of flexible tubes and thus contain a wider range of distributable holes. Their large size allows air diffusers to be bent into many unique shapes.
As the material is more akin to rubber, they give the grower more control of the manufacturing process while also reducing the load that is exerted on air pumps, prolonging their longevity. They are replaced less frequently and offer a substantially longer usage.
Used in conjunction with an air pump, diffusers and/or air stones enable the ecosystem to flourish.
Air manifolds and dividers – As a hydroponic garden grows in complexity and size, it is soon followed up with a need for how to divert the necessary oxygen and nutrient solution into each tank. This problem is most commonly resolved by manifolds and dividers.
Air manifolds give the gardener more control and allow for an adjustable flow of air.
Most manifolds are constructed to allow air stones or air diffusers access to air to ensure an equal airflow to each air stone or diffuser, usually numbering from 4 to 12 or more airways that are adjustable per the user’s needs.
They possess individual barbed valves that control each air outlet with precise design.
It allows the excess air pressure that comes from the air pump to escape to decrease pressure on the diaphragm of the pump, allowing for better performance and stability.
Dividers provide the much-needed space between plants. As the setting and diversity of the garden grow, so does the minimum growth space of each plant demand separation.
Dividers offer the gardener specified places that can accommodate a pre-determined plant with enough room to flourish unhindered.
Grow Lights–A facultative yet often bought choice are the grow lights. They differ from the standard household lights we are all accustomed to because they emit a definite color spectrum that imitates the sunlight plants use for photosynthesis.
Different grow lights are available for different hydroponic systems (depending on the size and the intensity) as they are invaluable if the setting where the plants grow has no or limited access to sunlight.
