How To Use Grow Light In A Small Greenhouse

You only need two factors to know how to use grow light in a small greenhouse, identifying the correct color and the type of light. With the extensive list of grow light available in the market, it can be overwhelming to understand how to use one. Therefore, learning these two factors first should make it easier to know the proper usage of a grow light in a small greenhouse. 

The regular check-up of the indoor conditions is necessary to maintain a small greenhouse. Failure to provide the optimal conditions indoors will affect your plants’ growth, health, and productivity. If the small greenhouse has inadequate light, plants won’t manufacture carbohydrates and have their energy reserves lost.  

Much like maintaining a regular greenhouse, do not make the mistake of overlooking the usage of grow light in a small greenhouse. They may have a smaller size, but the plants’ requirements growing inside are still the same.

Comprehensive Guide On How To Use Grow Light In A Small Greenhouse


The correct color

One of the most confusing aspects when using a grow light is knowing what color to use in the greenhouse. There is no difference with the correct color to use, whether you’re using a small or regular greenhouse. The bottom line is that you want lights with wavelengths of red and blue


Red and blue

The grow lights in the greenhouse may seem white to the naked eye, but they have wavelengths. Red and blue lights are best for grow lights because they affect how the plants synthesize nutrients. Therefore, they are responsible for energy and growth.

Choose lights that manufacturers label as balanced, full-spectrum, or natural. 


High spectrum vs low spectrum

Additionally, some grow lights may have numbers indicating 400K or 2700K. Use this as your guide where the higher the number, the colder the light. This is why most gardeners who use grow light to encourage foliage choose 6500K. 

On the other hand, your plants will also need a warm grow light at 3000K if you’re focusing on fruit production. Keeping this in mind, you can start with high spectrum lights for producing seedlings. Afterward, use low spectrum bulbs to help with flowering and fruiting. 


The type of light



The most inexpensive light that you can use in the small greenhouse is incandescent. However, they get hot fast, so you have to ensure a safe distance around 24 inches away from the plants. Besides being cheap, incandescent bulbs are also easy to install. 

However, they have a short lifespan compared to others and replacement will be more often. 



The University of Missouri Extension mentioned that fluorescent lights are one of the best options for indoor usage. For starters, this type is more energy-efficient and long-lasting compared to incandescent. You would also be less worried about the heat they produce, and you can choose from sizes and shapes suitable for a small greenhouse. 

Fluorescent bulbs give off blue light, but there are also full-spectrum lights, ideal for a grow light.  



You can differentiate high-intensity discharge lights into high-pressure sodium and metal halide, and they make the best supplementary lights. High-pressure sodium lights emit red, which is best for budding and flowering. On the other hand, metal halide is a blue-colored light that is useful to encourage growth. 

These lights are also energy-efficient and long-live, but they are best for large scale greenhouses than small ones. They have large fixtures, and it’s hard to find lights of this type in small wattage. Additionally, they emit heat, so positioning them in a small greenhouse is tricky. 



The most comfortable and perhaps the top pick grow light in a small greenhouse is LED. Unlike the HID, LED lights are small, lightweight, and easy to install, making them ideal for a mini greenhouse. They are also long-lasting without the danger of heat, and you can choose from different spectrums.


How to use a grow light

After understanding the two crucial factors, you can easily use a grow light in a small greenhouse with confidence. Start by knowing when to use a grow light, which depends on your plants’ specific requirements. Afterward, design the set-up for the grow lights to be at a safe distance from the plants.

In general, you can have the lights 5 feet away from the plant, but you can adjust this depending on the need of the specific species. If you want to save time and effort, you can also install a switch for the grow lights. Some can utilize a timer, but others even allow connection to your phone. 

Over time and as the plants grow, remember that repositioning the lights will be necessary. You might even need to change the spectrum and the duration of usage of the lights. 



Light is a crucial factor for plants’ growth and health, so greenhouse growers must provide the optimal lighting conditions indoors. You can quickly learn how to use grow light in a small greenhouse or for any greenhouse in that matter by considering the color and type of light.

Once you understand the importance of spectrums and differences among light types, you can go on with the grow lights’ set-up. Put them at a safe distance and adjust according to the requirements of the plant.

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.
