Thought about Mini Greenhouses Project

best mini greenhouse

Let’s do some research and know all about mini-greenhouses. Why we should implement in our home whatever indoor or backyard and how many types of Greenhouses are available in the current market. Through we have covered and discussed the only small type but larger greenhouses are remained out there and have also enough good features too.

What is a Mini Greenhouse?

You may have come in contact with the term mini greenhouse in recent times quite a lot. We also discussed some mini-greenhouses that can work. But what is it? Why is it called a ‘mini’ greenhouse, and how does it differ from the regular ones?

Well, the term is generic and can show a large array of unique designs. But, to specify the term, the mini greenhouse is a smaller-sized greenhouse that is shorter than 3 meters or 10 square feet.

This type is chiefly employed to germinate seeds than growing larger plants. Metal is mostly used as a building material, but plastic can also be used. A PE cover is often used to maintain humidity and harness the sun’s heat.

Because of being small and effective, these greenhouses are up on the trend right now!

What a Greenhouse Actually Does?

We all know about the greenhouse effect as a threat to our environment. Interestingly enough, the same effect is actually used to our benefit when it comes to greenhouse gardening.

A greenhouse has a glass ceiling. It allows Light transmission into it through this glass. However, the same light that enters easily through the glass can’t get out as easily. So what enters as shorter-wavelength infrared lights turns into longer-wavelength electromagnetic energy after being captured in the greenhouse. This energy doesn’t disappear even if the sun goes down. So with the help of this energy, this stays warm, and the plants in it absorb this energy to conduct the photosynthesis process or create food for themselves.

Where the true strength of a greenhouse really comes to play is when you come face to face with an environment that is not ideal. For example: in extreme heat, you can cool it with a cooler, and in extreme cold, you can heat it using greenhouse heaters.

Why Do You Need a Small Greenhouse?  

We strongly believe that in our current day and age, you need a small greenhouse. Here are some reasons why:

Firstly, we all know about the current environmental crisis that is going on. Our earth is suffering greatly due to environmental pollution. The effects of this pollution can be seen in nature. Harsh weather conditions are a common phenomenon along with natural calamities. These can greatly affect the growth of crops in regular fields and gardens. However, since you can create an artificial environment in your glasshouse, you can keep your plants safe from outer hazards. Also, greenhouse gardening is very environmentally friendly. So if you want to help the environment while continuing your harvest, then you should consider getting a small one.

Secondly, it comes with great benefits as compared to their bigger counterparts. This is your best friend if you don’t have a lot of space. Maybe you don’t have any place to farm outdoors, so you can just settle indoors. The best small greenhouses also come with multiple layers. So in one, you can plant different crops in different layers. It is quite portable. So if you for any reason need to move around, then a small one is the best choice for you.

Thirdly, a small one serves as a great entry point to greenhouse gardening. We believe that this type of gardening is quite easy, and everyone can find success in this field. But if you would like to get some practice before moving on to a professional, then you can practice and hone your gardening at a small one. You can try growing easy-to-grow crops for beginners and gain the experience and courage to pursue greenhouse gardening professionally.

One of the key jobs of a small greenhouse is seed starting. Let’s look at how you can grow plants in it all year round!

Growing Plants in Spring

At this time of the year, you can use the mini greenhouse to grow tender plants. Use this period to enlarge the young plants and later transplant them to other areas. One key idea is growing salad crops.

They are usually grown straight from the seed. So, you can try getting fresh salads from throughout the year!

Greenhouses Advantages and Disadvantages

A small greenhouse comes with so many benefits that it is almost unfair to its competitors. We shall discuss only a few major benefits here:

A very good hobby

Let’s start with the most basic premise. You might want to start greenhouse gardening casually as a pastime. A small garden is your best friend here because you don’t need to invest a lot of space, time, or resources. It takes up only a corner of your room, so you don’t have to worry about space. You can grow plants in it all around the year, so there are no time constraints.

Actually, a portable greenhouse is quite cheap, and the materials you need to grow plants like vegetable and herb garden is also very affordable, which saves you a lot of money.

Extra protection

Not everyone is going to be kind to your mini greenhouse garden. We are, of course, talking about angry mother nature and pests or rodents.

It is usually very portable. So in an event where there is hostile nature or environmental hazards outside, you can just carry your garden (you know what I mean) inside or to a safer place.

Also, since you’re not directly connected to the ground level, the pests and rodents will have a hard time infiltrating your precious greenhouse. Most comes with water and bug resistance ensuring great security.

Great flexibility or Better Mobility

The biggest benefit of a small one is its flexibility. Since a portable greenhouse comes in different layers. This actually means you can harvest a seasonal crop and prepare seedlings in a single one. Many additional attachments allow you to make them more beautiful and feature-rich. You also have the flexibility to switch between casual gardening or make an entire career out of it.

Furthermore, you can move them to desired locations, like moving them to shades during mid-summer and shifting them where they get the sun during the winter times.

Doesn’t Require Much Space

Mini greenhouses, just as the name suggests, are way smaller than the typical large-scale greenhouses. That’s why mini-greenhouses can fit in almost anywhere! So, you can utilize them even when there’s not enough space available where big greenhouses are not usable.

Grow Veggies Off-Season

Another reason why you may want to have a greenhouse is its ability to offer herb garden, flower garden, and veggie all year round—especially having off-season vegetables whenever you want them. Control the climate inside and grow your desired item anywhere!

Can be used in Experimentations

If you’re a horticulture enthusiast, then a mini greenhouse can provide tons of benefits. You can employ it heavily in terms of experimenting with different plants and how they do in controlled environments.

How to Choose a Greenhouse- Buying Guides

best mini greenhouse

There are a lot of options when it comes to buying a portable greenhouse in the market. Not all of these options are good, though. We have already presented our top picks to you in this article. But if you want to judge these greenhouses on your own or make the best decision, then we got you covered. Here is a list of things that you need to consider when picking the best one.

Aesthetics or performance?

Now some of you will care a lot about your greenhouse looks, while some of you will focus much more on how well the product performs. Both great looking and average are looking in the market.

You may not care much about how a greenhouse looks, but we would like to remind you that the greenhouse you buy will be most probably a part of your home for a good amount of time. So you must consider if you want to add to your aesthetics or not.

Proper Ventilation

Proper ventilation is the most critical and vital factor in a greenhouse. If adequate ventilation is maintained, the plants will get the necessary input to grow in the correct order.

Another positive outcome of a quality ventilation system is, it helps retain the correct temperature inside. Because of all these multiple reasons, you need to get a greenhouse that has an effective ventilation mechanism enabled.

Surrounding environment

It is known for its adaptability to the surrounding environment. But the thing about the environment is that it can get pretty hostile and extreme. So you have to consider your outside environment while buying a mini or portable.

If you buy a greenhouse or tent made with cheap materials like wood or plastic, then it might not last long in hostile weather. In this case, we recommend a resistant aluminum vented cold frame mini greenhouse kit for good durability and lightweight or steel for even better durability but heavyweight.

Also, using a polyethylene cover is cheaper than using glass, but it doesn’t last quite as long.

Scope and functionality

You will also have to consider the scope in which you would like to pursue greenhouse gardening and if functionality is enough to help you achieve your goals. If you aim to grow simple plants and just pass the time, you probably don’t need a feature-rich greenhouse. On the other hand, if you are planning to take on greenhouse gardening professionally, at a considerable scale, or to grow cultivated plants, then cheap greenhouses will probably not help you.

Size of the Greenhouse

Although all the mini-greenhouses are quite smaller in size and shape, yet, you need to understand the different types of designs that’d fit a particular place in the house.

Most have a long-standing design that doesn’t take up much floor space. On the other hand, some have a laid design that takes a bit more room but is better against windy situations.

Additional tools

Another thing to keep in mind, you will need the small greenhouse kits to work best. So make sure you consider getting a heater, cooler, light source, greenhouse cover, thermometer, seed trays, and plant pots according to your needs. Don’t drop too much money on a fancy-looking greenhouse and then not back it up with proper tools. You have to remember that it will carry and protect your plants, but you will need good seeds, light, heat, or breeze for the plants to grow correctly.

Superior Quality PE Cover

The PE cover is a highly critical element of a greenhouse. PE cover works as the main component that maintains the environment inside. So, you can guess how important this is for a greenhouse.

So, your responsibility would be to find out a greenhouse solution that offers steller PE cover with it. It’d surely play a role in terms of making the entire system work with much efficiency.

Ease of Assembly

Assembling the greenhouse remains one of the most challenging tasks for any user. If you don’t want to waste the entire day putting in a small greenhouse, it’s’ not worth it.    

And after spending the whole day behind it to see that the greenhouse isn’t standing right then, it’s a complete waste of time and energy. That’s why we’d always suggest those particular ones that don’t come with a complicated installation process.

So, if you consider these few criteria before purchase, we’re positive that it’d be possible to filter out a quality mini-greenhouse easily!


  • Can I use my greenhouse both indoor and outdoor?

Yes, you can. Most small greenhouses are portable, so you can use them both indoor and outdoor. However, do note that you might have to provide light, heat, or cold in case of indoor usage.

  • Is there a weight limit for the plants that I put in the greenhouse?

Yes, there is a limit. We don’t recommend putting heavy plants in it, made of cheaper materials like wood or plastic.

  • Are the greenhouses heated?

No, they are usually not. It depends on external sources like the sun or heaters. Some expensive models may come with built-in heaters.

  • How do I set up the greenhouse?

Usually, most greenhouses come with instruction manuals that help you set up. Some will come with links to websites that offer you a tutorial on setting up your greenhouse.

  • What can you grow in a mini greenhouse?

Some well-known and easy to grow recommendations are carrots, eggplants, asparagus, green onions, turnips, spinach, microgreens, kales, zucchini, salad greens, tomatoes, cucumbers, strawberries, raspberries, cherries, peppers, grapes, cantaloupe, lemons, chilies, sage, cilantro, mint, rosemary, catnip, cumin, sunflowers, marigold, peace lily, daisy, etc.

Final Verdict

The greenhouse is the future of gardening. Whether it be to grow our own plants, protect the environment, grow plants all year round without any seasonal barriers, create new jobs and careers, or just pass the time using it as a hobby, greenhouse gardening is the one-stop answer to all these issues.

Since this type of gardening hasn’t been mass-adopted by the public yet, you can start your mini greenhouse gardening journey now and get ahead of other people. We recommend using our guide to find the best small greenhouses for you and step into the future.
