How Do You Aerate Hydroponics. The Best 5 Ways

If you’re curious about how do you aerate hydroponics, there are five methods that you can choose from. They include suspension, using a diffuser, air stone, siphon, or air gap. As this article will later discuss, it is vital to aerate the hydroponic system to provide oxygen to the roots. 

The most significant risk for the plants with this limitation is as extreme as death. Studies have also shown how aeration improves the plants’ growth because of its effect on the roots. Much like the water in hydroponics, the air is a significant factor that gardeners must never overlook. 

How Do You Aerate Hydroponics. The Best 5 Ways

How Do You Aerate Hydroponics Correctly



The simplest way to aerate hydroponics is by suspending the plants. Instead of the traditional and popular system where you let the plants sit in water, you can consider having a vertical set-up instead. A vertical hydroponic system, in comparison, will feed the nutrient solution from the top and collect at the bottom, which then drips to the roots. 


Air diffuser

A common way to aerate hydroponics is by using an air diffuser. It may sound complicated, but a diffuser is simply a tube with holes. These holes will then be responsible for releasing air into the system.

If you’re comparing an air diffuser to an air stone, the latter’s main advantage is that it releases smaller bubbles. Their size prevents them from rising too quickly, which exposes the roots to oxygen longer.


Air stone

While air stones produce larger bubbles than an air diffuser, it also has several advantages from the previous method. Air stones provide a more even air distribution since the holes have better dispensation. The disc-type air stones are also excellent if your plants have an extensive root system.

Air stones are the most affordable option for aerating hydroponics and are even easy to find. You are also likely to find a suitable size and shape for your hydroponic system. However, make sure to get those with plastic since air stones break easily. 



There are other types of hydroponic systems that can benefit from an automatic siphon for aeration. For example, a flood and drain system or ebb and flow system will work best for this method. This is because a siphon will drain the hydroponic bed for you, thus exposing roots to air. 


Air gap

What if you’re using a Nutrient Film Technique (NFT) hydroponic system? This system does not use a substrate and relies on coating the roots with nutrient solution. An air gap in the system works best for aerating it. 

It’s as straightforward as it sounds where there is an air gap between the nutrient solution and the plant’s base, and it will provide the oxygen for the plants. 


How Much Air Do You Need For Hydroponics?

It’s possible to over-aerate a hydroponic system, mostly if you skipped planning. Remember that you’re only aiming to avoid being anaerobic, but you can also use the ratio below. 


100 LPM for every 100-gallon reservoir

When aerating a hydroponic system, you must know how much air it needs to ensure that the system will have adequate oxygen levels. Generally, you want to pump a liter per minute of air per gallon of a nutrient solution. Use this as your guide when computing the air requirements, so if you have a 100-gallon reservoir, the air you need to pump is 100 LPM.


Importance Of Aeration In Hydroponics

One might wonder why aeration is essential in a hydroponic system, and the explanation behind this lies in the amount of oxygen that your roots will have. To prevent limitations, it’s crucial to aerate the system. What are the effects of low or lack of oxygen in hydroponics?



If the plant root suffers from low or lack of oxygen, you’ll notice that the plant starts wilting quickly. This is more obvious in certain plant types or if the location is warm with high light. If you’re using a greenhouse, you can easily detect which factor causes such signs. 

Some set-ups, such as static culture systems, have low oxygen available since the plant roots are in the water permanently. This makes the hydroponic system problematic for larger crops since they have higher nutrient requirements, and oxygen limitation becomes detrimental. To solve this dilemma, you can use an aeroponic system that provides both nutrients and oxygen requirements. 


Problems in water and mineral absorption or toxin accumulation

Overall, it’s vital to keep the hydroponic system’s oxygenation potential in check if you don’t want plant growth problems. The lack or insufficiency of oxygen even affects the roots’ permeability, leading to toxins accumulating to water and mineral absorption issues.

Both static and dynamic set-ups require such diligence, and you can do so by monitoring the quantity and frequency of aerators or the cultivation media’s drainage and irrigation.



The roots of your plants in hydroponics must receive oxygen optimally. But how do you aerate hydroponics? You can choose from five methods depending on which is suitable for your set-up.

You can create a vertical system and suspend the plants or choose from using a diffuser or air stone. If you have a flood and drain system, you can opt for an automatic siphon for aeration. On the other hand, an air gap should provide the roots of oxygen in NFT systems.

How to Start an Avocado Farm: 4 Things to Remember

How to Start an Avocado Farm: 4 Things to Remember

Are you interested to learn how to start an avocado farm? Embarking on this journey requires time, effort, and commitment. Plus, you need to consider a number of factors including soil preparation, as well as weather conditions.

You’re probably aware that avocado trees or Persea spp, are originally from Mexico. This explains why one of the famous Mexican cuisines include avocado-based guacamole.

You can choose to grow avocado trees indoors or outdoors. If you plan to grow them in a hobby greenhouse or at home, all you have to do is to sow the seeds in pots. When they’re grown outdoors, avocado trees can grow up to 40 feet. You can al

Moreover, these trees thrive well in regions where the weather is mostly warm and sunny. However, don’t expect them to grow in areas that experience extreme temperatures during the summer and winter.


Avocado: The Superfood

Did you know that the global demand for avocados has been steadily increasing? Aside from the fact that its fruit is known for its full, buttery flavor and rich texture, it’s also packed with loads of essential nutrients that are good for your body.

A single serving of avocado fruit contains vitamin K, vitamin C, folate, potassium, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin E, manganese, magnesium, iron, copper, zinc, and vitamin A.  It also has protein, fiber, and healthy fats. If you’re on a low-carb plant food diet, you’d want to incorporate avocados into your diet.


What are the Growing Requirements of an Avocado Tree?

Since avocado trees need to be grown in warm semi-humid climates, they only grow in U.S. Department of Agriculture (USDA) plant hardiness zones 8 to 11. However, it’s important to note that while avocado trees may be grown in those zones, they don’t always thrive well in areas that get extremely hot during the summer or frosty, chilly, or snowy in the winter. This implies that the ideal environment for an avocado tree should have moderate temperatures all-year-round.


What are the 3 Primary Groups of Avocado Trees?

If you’re planning to start an avocado farm, you need to know the 3 main groups of avocado trees: Guatemalan, West Indian, and Mexican. Each type has its own ideal growing range.


Guatemalan Avocados

A Guatemalan avocado is known for its hard skin that features plenty of warts.


West Indian Avocados

This type of avocado tends to flourish in warm climates. Unlike the Guatemalan avocado, a West Indian avocado has thin and shiny skin and could weigh up to 5 pounds.


Mexican Avocados

A Mexican avocado thrives well in tropical highland areas. Compared to the other avocado groups, the Mexican avocado is more tolerant of cold weather. In fact, it can manage to survive even when temperatures drop to 26˚F.

Moreover, this type of avocado produces smaller fruit that weighs less than a single pound and its skin has a distinct papery-smoothness to it.


Expert Tips on How to Start an Avocado Farm

Unless you’re willing to take on a long-term project, spend a considerable amount of money on planting, and wait for a period of 3 to 5 years for your first harvest, don’t get into avocado farming. However, if you’re willing to go through the whole nine yards to enjoy top yields for many years, check out this guide:


Tip #1: Plant them in areas where the temperatures are consistently cool

Be sure to plant your avocado trees in cool temperatures that can range between 68˚F to 75˚F on a daily basis to avoid fruit drop. However, when they’re flowering, or when they’re starting to bear fruit, the humidity levels shouldn’t go below 50% at midday.


Tip #2: They don’t like wind

In case you’re not aware, avocado trees have brittle branches that easily snap off. For this reason, it’s best not to plant them in areas that are mostly windy because wind can cause considerable damage to their fruit.


Tip #3: Most of them need proper irrigation

If your avocados are rain-fed, they need to have at least 1,000 mm rainfall spread out throughout each year. Before their flowering season, avocado trees require a drier season that lasts for about 2 months. On a weekly basis, avocado trees need about 25 mm water.

It’s extremely important to test the quality of irrigation water because if its pH and bicarbonates are really high, they trigger a build-up of free lime in the soil. You also need to remember that high levels of sodium and chloride can have a negative impact on your avocado plants.

Since the plant’s roots are shallow, the ideal way to apply water is via a micro-sprinkler or drip. This ensures an even distribution throughout the avocado tree’s root area.

Moreover, proper moisture control needs to be ensured in the root zone because this area tends to easily dry up.


Tip #4: Determine the soil’s suitability and prepare it accordingly

You can’t just plant an avocado seed on soil that hasn’t been prepared accordingly. To prepare the soil for planting, you need to dig soil profile pits throughout your farm. Make sure that the pits are 1.5 m deep.

Only a single put per ha is required. However, you need to dig more pits if the location is non-homogenous or hilly. Check the color of the soil, its texture, structure, patches, sitting water, concretions, hardpans, stones, and gravel.



Grow Your Avocado Trees in a Hobby Greenhouse!

Since avocado trees require specific levels of temperature and humidity, you’ll find it easier to grow them in a hobby greenhouse. The enclosed space allows you to customize the environment to meet the needs of your plants. What’s more, it protects them from strong winds and the constant threat of pests.

Learning how to start an avocado farm outdoors is great, but growing them inside a hobby greenhouse is even better.
