There is a common question among greenhouse owners: “What can you grow in a little greenhouse?” In a tiny greenhouse, you can grow just about anything. Indeed, a greenhouse is the best place to grow most types of plants and produce.

Mini greenhouses

With its compact dimensions, the mini greenhouse is ideal for those who live in apartments or smaller homes with limited or no outdoor space. When it comes to a little greenhouse, there are a lot of options to select from! A polycarbonate (or glass) cover is applied to the wooden or aluminum frame. Mini greenhouses with plastic foil covers can also be found, but these tend to be a little taller and have a few shelves inside.

There are a few things to keep in mind when deciding whether or not to put a planter outside, especially if it will be exposed to the elements. They are less of a design accent to your home environment because they have a less slick surface on the plastic foil greenhouse. The fact that it’s portable is a huge plus. During the winter, you can leave it out in full sunshine, but you may want to shield it from the sun during the hottest months of the year. You can transfer it to a new location and utilize it as both an inside greenhouse and an outdoor one.

Do Plants Grow Better in a Greenhouse?

You can cultivate a certain type of plant in a controlled environment created specifically for you in a greenhouse. The greenhouse protects your plants from the elements, no matter what the weather is like outside. You can cultivate both warm- and cold-season vegetables in your greenhouse. Watering can be automated, for example, by using a timer. When it comes to watering your plants and regulating the environment, this is a time saver.

Plants that require warmer conditions can be grown in the cooler months, and vice versa. To ensure that your plants receive a consistent supply of carbon dioxide, an automatic ventilation system can be installed in your greenhouse. Sugar and oxygen generation in your plants depends on CO2. They will be able to generate larger leaves and stronger stems as a result of this procedure. The likelihood of early flowering or fruiting is also increased when there is sufficient CO2.

What Plants Can You Put in a Greenhouse?

The variety of crops that may be grown in a greenhouse makes it a lot of fun. Some of the plants you can grow in your greenhouse include:


Tomatoes can be grown on the ground or in a greenhouse, and both methods are simple. They enjoy the heat and can’t stand the cold. Tomatoes might become pale and fragile if they don’t get enough light. Your plant’s soil should be well-oxygenated and moist, but not soggy. To ensure a healthy start, only plant one seedling per pot.


One of the most typical crops grown in greenhouses is strawberries. Strawberries picked straight from the greenhouse are superior to those purchased at the supermarket. Plus, you can be certain that your strawberries are free of dangerous chemicals, pests, and diseases if you grow them yourself.

Using pots with well-draining soil is the best way to grow strawberries. Mulch can be used to regulate the temperature of the soil. Strawberries have shallow roots, therefore drip irrigation is recommended. Pests and sickness may be attracted to your home if you drop water from the sky.


The coolness and hardiness of spinach make it an excellent choice for year-round growing. Cold weather is ideal for these plants to thrive. It’s best to grow them in well-drained soil, in partial shade, or even in full sun. Spinach should not be grown in soil that has a temperature of more than 70 degrees Fahrenheit.


It’s easier to sow kale in seed trays rather than directly in a seedbed because it’s more convenient. Because it is one of the most disease-resistant greens, kale is one of the easiest plants to grow. All you have to do is remove any fading leaves and keep the weeds at bay. Even in sandy soil and partial shade, kale can thrive.

Salad Greens

Did you know that you can grow lettuce, romaine, beet leaves, and other salad greens all year round? At the very least, you should be able to plant two seeds each week. Before planting them in your garden, allow them to grow for a few weeks to a month.

Green Onions

Climate-controlled greenhouses and coastal areas are the best places to grow green onions. They’re one of the simplest crops to grow and manage as well. Gardeners often promote onions as ideal beginning plants because of this.

Green onions can be grown from seeds or sets, but the simplest method is to start with sets. Gardeners who live in warmer areas should plant the bulbs in soil that is well-oxygenated. Once your plants have swollen, you should stop watering them. When the foliage turns yellow and dies back, that’s the time to harvest it. Finally, leave them out in the sun to dry for a few days.

Investing in a Mini Greenhouse – Is It Worth It?

Because of its adaptability and simplicity, a tiny greenhouse is a worthwhile investment. Plant diversity, temperature control, and a longer growing season are all possible outcomes. In addition, a small greenhouse is a wise investment because of the following factors:

Best for gardeners with limited space

Try producing fruits and vegetables even if your garden has a small amount of outdoor area. Anywhere from a balcony, patio, deck, or tabletop can be used as a mini-greenhouse. It doesn’t matter how small your mini-greenhouse is; it still has the same advantages as a full-sized one.

Protect tender plants

During inclement weather, you can bring delicate plants into a greenhouse and protect them from the elements. You can shield them from the elements, such as frost, storms, and heavy rain, by doing so. After a few days of dry weather, you can replant them in your garden.

Repel insects and critters

Your plants are a favorite meal for insects and other wildlife. Use a tiny greenhouse to keep them out of your plants and prevent them from eating them.

Extend your growing season

You may get a head start on spring planting by setting up a small greenhouse before the first frost arrives. With an early harvest and new plantings, you’ll have more time to enjoy yourself.

What’s a mini indoor greenhouse?

It’s exactly what it sounds like: a small indoor greenhouse! It’s a tiny little thing. It’s a sheltered area. And because it’s a greenhouse, the plants are protected and kept warm by the structure’s glass walls.

For the most part, people picture an outside greenhouse when they think of a greenhouse at all. These can be found in a wide variety of forms. Attached to an existing structure or standing alone, these additions are available in a variety of forms. The size of an outdoor greenhouse can range from a few shelves to the size of a commercial nursery, depending on the needs of the owner.

A tiny indoor greenhouse is obviously constrained in terms of space. In order to be used indoors, they are compact in size. Prefabricated homes, on the other hand, come in a wide variety, as you’ll discover if you start looking. In some cases, they are formed like boxes that can be moved to different parts of the house with a stable bottom. Small indoor greenhouses can be placed on tabletop, windowsill or in front of a window if they are freestanding constructions that are around the size of a bookshelf.

An indoor mini-greenhouse is constructed in the same way as an outdoor greenhouse: the frame and the cover go together. These can be created from a variety of materials, as we’ll see.

Other options besides greenhouses

As an alternative to greenhouses, row covers, cold frames, or covered raised beds can also be used to protect and save heat for plants. Row covers are often composed of hoop frames and a flexible cover, such as plastic sheeting, to create a low tunnel over a row of plants in a garden.

Low-lying structures with a transparent lid and insulating sides are known as cold frame boxes. The sun’s heat is retained by them, allowing plants to grow longer. Unlike row covers, which are affixed to rows of garden beds, covered raised beds are fastened to raised beds. Since they have a rectangular shape and sturdier structure, they can be created in many ways: as an A-frame with sloping robust walls, or as an A-frame, with a low-walled and flat roof.

Outdoor vs indoor mini greenhouses

In other words, little indoor greenhouses. I see now. Alternatively, how about constructing a little outdoor greenhouse? What’s the big deal? Choosing between a small outdoor and an interior mini-greenhouse may be a difficult decision.

For starters, you won’t have to contend with the wide range of temperatures that you might encounter if you were outside. There is no need to worry about temperature fluctuations or how to put together a heating system to keep the greenhouse warm in the winter. There is no additional cost or hassle to keep your greenhouse warm because you already keep your home at a temperature that is ideal for living. It’s important to bear in mind, though, that if you have a greenhouse in your home, the temperature there may be significantly greater than what your thermostat is reporting.

Glass, on the other hand, is generally not the material of choice for your home. Living in a “glass home” is an old adage, isn’t it? Unlike a standalone outside greenhouse, your interior greenhouse does not have a 360-degree source of light. Most indoor greenhouses can be moved about and rotated so that all of the plants get a chance to catch some sunlight. Grow lights can be added to your indoor greenhouse if additional light is required to help your indoor garden thrive.

Automated controls for temperature, lighting, ventilation, and watering are used in outdoor greenhouses. Because indoor greenhouses are so small, it is necessary to carefully regulate all of these parameters that lead to plant satisfaction. Even while there are exceptions — small greenhouses with automatic controls are definitely available — little indoor greenhouses normally rely on regular checks by the gardener. Your plants are right there on your windowsill or in the middle of your kitchen table, so this isn’t difficult to accomplish. Watering the plants or checking the weather doesn’t need putting on boots and a coat and trudging outside.

Pros and cons of mini greenhouses

Lists are my thing. When comparing indoor greenhouses to outdoor greenhouses, below are the advantages and disadvantages of each type of growth environment:

  • Don’t occupy too much room.
  • If you want to do it yourself, it’s simple to make.
  • If you’re not a fan of the concept of making your own, this is a good option.
  • In your kitchen, you may be able to keep it easily!
  • Low-maintenance
  • In the event that you’re utilizing grow lights, heaters take up a lot of room and energy.
  • Because you have a smaller garden, you can only cultivate tiny plants.
  • A smaller selection of off-the-shelf solutions for automating watering and ventilation are typically found in the market.
  • More cloud cover, which may necessitate the usage of grow lamps.

Good materials for mini-greenhouses:

There are an infinite number of ways to create a tiny greenhouse in your home. It is possible to use anything that can be wrapped in a plastic or glass container. The cover, whether made of plastic or glass, must be clear in order to capture the sun’s rays. To begin with, you may not have realized it, but a greenhouse is nothing more than a structure that shields plants and captures sunlight for them. There was a picture of one on the internet that was little more than a clear plastic umbrella buried in dirt.

Here are a few examples of basic DIY small greenhouses that you can build yourself:

  • Egg boxes
  • Containers made of plastic (muffin containers are perfect for seedlings)
  • Plaques for displaying photographs
  • Boxes made of glass
  • Bags of plastic
  • Bins made of plastic
  • wire containers
  • Wrap in plastic
  • Petty bowls

What can I grow in a mini indoor greenhouse?

When it comes to gardening, the only thing you’re really limited by is the amount of available area. A micro greenhouse’s smallest component. In the end, you’ll have to give up your fantasies of swaying vines and enormous zucchinis. If you are unable to supplement with grow lights and have little sunlight coming in from a window, your limitations may be based on the amount of sunshine your plants have access to. A shade-loving plant like herbs or greens would be a suitable choice here.

Small herbs

  • Having access to fresh herbs throughout the year is a wonderful perk of growing herbs inside. An appealing supply of flavorful and fragrant herbs for cooking is the ideal kitchen accessory. When it comes to recipes that use a single herb, there is no substitute for the actual thing. The powdered form is a poor substitute.
  • The herbs that originate in warmer climates are a wonderful choice if you have enough of sunlight, like beside a south-facing window Rosemary, thyme, basil, and oregano are just a few examples.
  • When it comes to herbs, parsley, chives, and mint all do well in cooler climates and with less sunshine.
  • Herbs have a tendency to grow out of control. Some herbs require more or less water than others, depending on their specific needs. As a result, it’s possible that putting each herb in its own container will keep them all happy.


  • For a variety of reasons, succulents are a popular choice for the home. First and foremost, they’re easygoing home guests. Designed for dry circumstances, they’re a wonderful option for the dry winter months. Overwatering will kill them, so don’t waste your time watering them.
  • Succulents are native to dry, sandy soil environments. Plant them in a mixture of half potting soil and half sandy soil to help them adjust to their new surroundings.
  • Succulents have a cool appearance. They simply do. An appealing greenhouse and a grouping of succulents in attractive pots can be a terrific centerpiece if your home design is clean and modest. They are available in a wide range of colors, forms, and textures. Incorporating a soft, fluffy panda plant into an otherwise thorny cactus can result in a fascinating show.
  • Put your succulents near a south-facing window to ensure that they get plenty of sunlight. However, this isn’t true for all succulents, so double-check to make sure.
  • Wrinkling and dullness are two telltale signs that a succulent needs water. Before you add any water, make sure the soil is completely dry.
  • Aloe vera, for example, is both aesthetically pleasing and medicinally beneficial. Aloe vera’s gooey fluid is well-known for its ability to soothe burns and mend the skin.
  • Cacti, aloe vera, zebra plant, panda plant, bird’s nest sansevieria, and string of pearls are all examples of succulents. Kalanchoes and Christmas cacti, for example, have stunning blossoms.

Small vegetables

  • One of the fastest-growing pastimes today is food gardening. Many veggies can be produced in small spaces, even if you don’t have a lot of land to spread out over.
  • For a small greenhouse, look at tiny varieties. When it comes to growing your own food, you don’t have to sacrifice taste for convenience.
  • When it comes to indoor gardening, the best choices are greens like arugula, kale, and spinach. Having them fresh is the best way to enjoy them, and they can’t be preserved in the freezer from your garden. They also thrive in lower temperatures and less sunlight.
  • Small tomato types can flourish inside if you provide enough sunlight and maintain a warm enough temperature.
  • Microgreens can be harvested in as little as one week and take up minimal space while providing a plethora of nutrients. However, a grow lamp is required because they require 12-16 hours of sunshine each day.
  • Onions and cauliflower are just a few of the many crops that can be grown successfully inside. Take a look at what you and your family eat on a regular basis and what you’d consider worth the restricted space in your greenhouse before making a final decision on what to grow.

Small fruits

  • The list of fruits that can be grown indoors is as large as the list of vegetables. Fruits, on the other hand, require more sunlight and higher temperatures than most vegetables.
  • It is possible to cultivate berries, figs and even melons inside. Because strawberries don’t take up a lot of room and yield fruit rapidly, they are a popular choice.
  • It is possible to buy dwarf types of fruiting trees that can be grown all year round.

Small flowering plants

  • The winter months are the perfect time to bring some color into your home by growing flowering plants indoors. If you choose the correct little greenhouse, you’ll be able to showcase your plants’ stunning blossoms. There are a wide variety of plants to choose from, ranging from prickly bromeliads to fuzzy chenille plants.
  • Plants that don’t require a dormant season are among the most popular indoor flowers, as they bloom throughout the year. Begonias and African violets are two examples.
  • The exquisite peace lily, which requires just moderate light and requires little care, is another excellent option because of its low maintenance requirements and mild fragrance.


  • For many people, the primary function of a compact greenhouse is to lengthen the growing season of their garden plants. In order to start seeds indoors, you just need a pot the size of a cupcake to hold the dirt.
  • Determine whether or not you can successfully transplant a plant variety before sowing seeds indoors. Your seedlings will die if you transplant them before they’ve had time to grow.
  • Planting instructions and recommended indoor seeding times are included in most seed packets, according on your area’s last projected frost date. If you plan ahead, you can avoid having to buy larger pots for your seedlings because they’ve outgrown their current ones before you’re ready to transplant them outside.
  • Harden off your seedlings before transferring them to their new home. This is a gradual process of acclimating them to the weather. The seedlings in your tray should be exposed to the elements for longer amounts of time before planting in the garden. Your time and effort aren’t worthless if your plants fail to grow after being transplanted.

How to make a mini-greenhouse:

Is there a way to get a tiny greenhouse? Many things are available, ranging from the purely functional to the utterly charming.

Creating your own little greenhouse is easy if you’re a do-it-yourselfer. These can be anything from cupcake liners to clear plastic umbrellas, as I’ve already indicated. Here are a few inspirations to help you get your mojo flowing:

Egg carton greenhouse

  • This is a very low-cost and straightforward solution. You can use an egg carton to fill each place with potting soil by cutting the lid off. After you have planted the seeds and watered the soil, you can cover the carton with something transparent, such as the lid of another container or a piece of clear plastic stretched across. Voila!

Plastic bag and wire greenhouse

  • A wire frame and a plastic bag cover are all you need to assemble this miniature greenhouse.
  • Use wire snips to remove the hook from a wire coat hanger. Bend the wire into a U shape and cut it in half. One U-shaped wire is sufficient for a small pot while two are required for larger ones.
  • Tuck in the bottom of your pot or tray by covering the wires and putting a clear plastic bag over the top of them. Untuck the plastic on one edge if it has gathered too much moisture and needs to be ventilated.

Plastic bin

  • Keep your seedling trays and plant pots organized in a clear plastic container. Remove the cover on a hot day to allow for better air circulation. Snap the lid on or drape a transparent sheet over your little greenhouse if you want to raise the temperature.
  • Instead of placing plants on the floor, you can cover them with a plastic container and place it on top of them.

Picture frame greenhouse

  • This is by far the cutest option on the list. In addition, it is the most time-consuming and labor-intensive. A year-round display piece rather than something utilized to simply start seeds can be of interest to you if you’re looking for that special something. For those of you who aren’t keen on the idea of having a wire-and-plastic-bag greenhouse on your windowsill, you may want to consider this alternative.
  • Depending on the tools you have and the look you want to achieve, there are a variety of tutorials available. The fundamental concept is to construct a little greenhouse out of picture frames, both old and new.
  • Remove the glass from the frames, sanding or painting the frames if desired, before reinstalling the glass. Allowing the frames to dry before securing them with screws or a hot glue gun is the recommended method of securing your finished project. Hot glue should be used to secure each pane of glass to its frame as you replace the glass from the bottom up.

Tips to keep plants healthy

Plants, no matter where they grow, require the same basic necessities:

  • water
  • sun
  • nutrients
  • air
  • appropriate heat

In a small greenhouse, it’s up to you to make sure the plants have the nutrients they require.

As a starting point, make sure that the area is free of dust and other debris. Plants should be checked for pests before being placed in a tiny greenhouse. Remove any pests or diseases from a plant as soon as possible. Keep in mind that your plants still need room to grow and avoid disease and pests, even in a small greenhouse.

Ensure that your plants get the water they need at the right time. To avoid a dry environment, spray them or move them to a more humid part of the house if necessary. Of course, the amount of water needed is dependent on the plant. When it comes to succulents, over-watering is a common problem.

In addition to providing your plants with nutrient-rich soil, use organic or non-organic fertilizer as needed.

Even though you’ve probably already considered this, it bears repeating: place your plants in a location where they will receive plenty of direct sunlight. It is important to rotate the pot or tray frequently to ensure that all of its surfaces receive an equal amount of sunshine.

Now, something you may not have considered straight away is the possibility that your little greenhouse can become too hot. Keep an eye on the temperature and make sure there is enough air movement and ventilation to prevent things from getting too hot and humid. Simply move your greenhouse or cover it with a fabric that will partially or completely hide the sun if your plants are suffering from excessive sunlight.


There is a vast range in the size and complexity of little indoor greenhouses. They might be as simple as a cling-wrapped egg carton or as complex as completely automatic systems. It’s possible that you’ll need these extras if and when you decide to grow these particular plants:

Grow lights

  • Grow lights can be a lifesaver if you’re short on sunlight. See our picks for the best grow lights. They can increase the amount of time your plants are exposed to sunshine, or the intensity of that light. They can also be used to grow plants that don’t have access to sunlight.

Small fan for ventilation

  • Add a tiny fan for ventilation if your little greenhouse is in a particularly hot and sunny region or is tall enough to require air circulation. This will maintain a constant temperature in the greenhouse and, if necessary, cool the plants.


  • In spite of the fact that you have a greenhouse in your house, it is designed to raise the temperature, therefore the temperature in your greenhouse can differ significantly from the temperature in your house. Monitor the temperature of your plants by using a thermometer.

Where should you place your small greenhouse?

Placement for any greenhouse should be based on maximizing exposure to sunshine. Make sure your greenhouse is facing the sun, whether it’s an indoor or outdoor one. During particularly hot summer days, use shade cloth and add a greenhouse thermometer if you’re concerned about your greenhouse becoming too hot.

What can you grow in a mini greenhouse?

You can grow vegetables and plants in a greenhouse, but we recommend that you use it primarily for herbs and seasonings. When we started growing tomatoes, we found that the little size soon became too small. Choosing only herbs gave us the freedom to experiment with a wide variety, including oregano, mint, hot peppers, basil, and more. As long as the little greenhouse gets enough sunlight to keep the herbs warm, they’ll be fine during the winter. All year round, you can enjoy the taste of homegrown spices!

Best 6×4 greenhouses

For those who wish to cultivate veggies and plants outside, but don’t have a lot of space to work with, a 6 x 4 greenhouse is the ideal solution. There are two primary types of 64 to choose from. Either a polycarbonate greenhouse with an aluminum frame or a plastic foil greenhouse are viable options. Both have their pros and cons, so think about what you want before making a selection. While plastic foil is less expensive, it provides less weather protection and has a shorter lifespan. If you plan on heating your greenhouse in the cold, this is not the greatest solution. In order to keep your greenhouse from overheating, you’ll need to utilize a thicker plastic foil.

Your choice of greenhouse depends on whether you plan to move it around or only use it for a short period of time each year. Insulation in a polycarbonate 6×4 size is better and more efficient, allowing for a wide range of alternatives. It’s a long-term investment that will serve you well for many years. They’re more expensive, but you’ll be able to produce nearly anything in them, including veggies throughout the year. Prior to making a decision on a greenhouse, take into consideration your budget, climate, the type of plants you intend on growing, and whether or not you plan on using it during the winter months, as well.

Best 6×8 and 6×6 greenhouses

Whether or not you consider this to be a little greenhouse is up to you. These are still considered small enough to fit in most backyards. Most of what we discussed in the 6×4 greenhouse is also relevant to the 6×8 greenhouse, but you’ll have more polycarbonate alternatives to pick from. Even small glass greenhouses in the 6×8 size range may be available. With a 6×8 greenhouse, you’ll have plenty of room for your plants to develop and thrive.

You can start with a decent-sized greenhouse in your backyard with this kit, and it won’t take up a lot of room. It’s important to remember that while a little glass greenhouse is the most beautiful alternative, it is also the most expensive. The beauty of these greenhouses is enhanced by the fact that they are even more durable than polycarbonate. Consider this option if you’re willing to fork over a bit more money! I believe we’ve demonstrated that there is a greenhouse to fit any situation. What if you’re still unsure? Please allow us to convince you to begin greenhousing right now!

How do I start seeds indoors using a mini greenhouse?

You may either buy a seed-starting kit or make your own to start seedlings in a little greenhouse. Cling-wrapped muffin tin or egg carton can serve as an excellent nursery for young plants. Soak the potting soil or seedling pots in lukewarm water for a few minutes to get the soil moist enough. Cover your greenhouse once you’ve sowed the seeds according to the instructions on the seed packaging.

How To Build an Attached Greenhouse Tutorial and Tips

The covering must be transparent so that sunlight can get through, and it must also keep moisture in. You don’t have to water your seedlings until you see them germinate since the moisture can’t evaporate. When they’ve sprouted, prop open the greenhouse’s cover to let water and air to get out and circulate. To keep the soil from drying out, water it as needed. Hardening off seeds before planting them in the garden ensures that they are ready to withstand the weather.

Which tomatoes grow best indoors?

Make sure you buy cherry or plum tomatoes if you want to grow tomatoes inside. Tomatoes from small-fruited vines yield more, ripen faster, and take up less room. Tomatoes are “heavy feeders” as compared to other plants, so make sure your soil is well-fertilized.

How do you use a mini greenhouse?

It is possible to raise a small number of plants to maturity or lengthen the growing season by starting seeds in mini greenhouses. You may make a mini greenhouse for indoors or outside.

Bring your passion for growing indoors with a mini greenhouse. Knowing the basics should help you see all the possibilities in and around your own house.

Final Thoughts: What Can You Plant in a Mini Greenhouse?

A tiny greenhouse is a great place to experiment with a variety of plants. Additionally, you may grow a wide variety of vegetables and fruits such as carrots, beets and okra as well as peppers, chili and even exotic plants!
