What Helps Greenhouse Plants Stay Small

If you’re wondering what helps greenhouse plants stay small, two factors generally affect their growth- temperature, and humidity. In this article, we will find out how greenhouse plants keep their size.

Without a doubt, greenhouses are ideal for growing plants; you have control of all the elements essential for your plants, providing you a better yield. This is true, especially for areas with a cold environment or where plants can’t strive, buying a greenhouse is the best choice. 

Now, it’s time for you to learn more, so just read on!

Factors That Keep Greenhouse Plants Small

In this section, we’ll discuss temperature and humidity; they’re the two main factors that keep greenhouse plants small. Later on, you will find out some of the things that can help control these factors. Let’s delve further so you will understand better.


Temperature and humidity to maintain plant size

Temperature and humidity go together when it comes to the growth of your greenhouse plants. This means that both of these factors are what helps greenhouse plants stay small.

Air’s temperature has an impact on the plant’s ability to holding moisture. Warm air holds more water vapor, which has higher relative humidity. Therefore, you can say that the temperature is relevant in controlling humidity.

Relative humidity, on the other hand, determines the amount of water vapor present in the air. It is expressed in percentage, and it shows how much is needed for saturation. This factor affects your plant’s biological process, especially on transpiration.

Transpiration is the process in which plants sips in water from its roots, transports water to its tissue, and release it back to the atmosphere through its leaves. It is essential for the growth and development of the plant. Also, it is responsible for releasing the water into the air, which helps the plant to cool down.

You may say that plants sweat too. If we sweat a lot in a very humid place, you’d feel uncomfortable, won’t you? Just as how relative humidity stops our sweat from evaporating, high humidity disturbs the transpiration process of your plant. It will be a threat to your plant’s growth.


How to control humidity and temperature

Now that you are familiar with the factors affecting your plant’s growth, you’d also want to consider the external factors outside the greenhouse as it could also affect what’s inside.

The temperature and weather outside your mini greenhouse changes. Therefore you’d want to maintain the condition inside to keep your plant healthy and growing properly.

Since humidity and temperature are what helps greenhouse plants stay small, you need to know how to control them. Here are the ways:


#1 For humid areas

If you’re already living in a humid environment, passive and active ventilation are popular. It is perfect for controlling the humidity and temperature in such an environment, as it moves the hot air up and out and cold air in, regulating the temperature.


#2 For dry areas

However, in drier places, evaporative cooling would be the best option. Ventilation isn’t enough since humidity in this area is lower. Evaporative cooling works by adding moisture inside the greenhouse environment; this will get rid of unnecessary heat while letting the moisture in.


The system controlling humidity and temperature

Now, you already know the ways on how to control humidity and temperature inside your greenhouse. We prepared more; you have to use equipment to help greenhouse plants stay small.

Here are some more things to use to control the humidity and temperature of the greenhouse:

#1 Use a fan and pad cooling system

A commonly used technique by plant growers involving a fan and pad system, a large wet wall is installed on one wall, and a series of exhaust fan placed on the opposing wall of the greenhouse. The pad is continuously released water vapor with the help of a water supply.

The air will then pass through the pad. The cold and humid air will then move towards the greenhouse with the help of the exhaust fan and released to the outside atmosphere.

It is easy to use and cheap. However, the pad is somewhat prone to bacterial growth and mineral deposit. The temperature gradients of both the pad-wall side and fan-wall side may be uneven.


#2 Use a high-pressure fog system

The system uses nozzles distributed evenly inside the greenhouse. Series of nozzles would then inject water droplets in the form of an artificial fog in your greenhouse.

A high-pressure fog system is a better alternative for pad and fan system as it gives even coverage and consistent atmospheric condition for your small greenhouse. But of course, it has its flaws as well.

You need to control the size of your water droplet; smaller droplets are not enough to give the moisture your plant needs, and bigger droplets might destroy your plants.


Both systems work just fine for any size of the greenhouse. However, if you’re looking for a cheaper alternative, then shade curtains will help you with that. Shade curtains will serve as a thermal shield and will keep heat if needed. 

It will help in reducing heat when the temperature outside is hot. In contrast, when you place sheer curtains at night, the temperature inside the greenhouse would be regulated if ever the heat outside drops.

But use it properly as it might hinder your plant’s photosynthesis and transpiration process.



If you think growing plants will only be watering them daily, then think again. Especially if you’re growing plants inside a greenhouse, you have to consider factors, not only inside but also outside, to maintain a suitable condition for your plants to grow.

Just a reminder, also put into consideration your environment before you construct a greenhouse for you to know what appropriate products to use. Again, water, sunlight, humidity, and temperature are some of the things you need to make sure to keep your plants healthy.

Once again, the relative humidity helps the greenhouse plants stay small. So, make sure to control the condition inside your greenhouse if you want it to be bigger. We hope that we helped you answer your questions. God bless, and thank you for reading!

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.
