The best indoor greenhouses

You may think you need a big yard, balcony, or patio to enjoy the pleasure of homegrown plants and vegetables? Think again! Thanks to an indoor greenhouse, you can still grow plants, vegetables, and flowers within the confines of your home or even bedroom. We’ve selected the 5 best indoor greenhouses money can buy. Read on.

Why an indoor greenhouse?

Indoor greenhouses offer you loads of benefits and you’ll find there’s a suitable option for everyone. Whether you’re going for a miniature greenhouse to start growing herbs in your apartment or you want a full-blown model to grow vegetables and flowers, we’ll help you find exactly what you need!

The benefits of an indoor greenhouse:

  • It’s easy to move. When you’re planning on moving out of your house or apartment in the next few months or even years, your hard work will be protected as it’s easy to move an indoor greenhouse to your new place.
  • You don’t need a yard, balcony or patio to enjoy fresh homegrown vegetables. Maybe you do have outside space but the climate in your region is not ideal for growing plants or the amount of sunshine in your yard is too low to benefit from a greenhouse. Enter the indoor greenhouse…
  • Your crops are well protected. When you buy an indoor greenhouse, your herbs and veggies won’t suffer from outside elements, such as rain, wind, and snow.
  • It’s easier to monitor the temperature and conditions in your greenhouse when it’s so close to you.

Where should you place your indoor greenhouse?

Ideally, your greenhouse is placed in a sunny spot, so your plants can benefit from direct sunlight. If that’s not an option for you, you can add lighting to your greenhouse. Take into account though that natural light is always better for plants to grow than artificial light, so ideally you will at least go for a combination of both and won’t completely rely on the added lighting.

Which crops should you plant indoor?

This strongly depends on how much room you have in your indoor greenhouse. If you only have a mini greenhouse, you should probably start with growing some beautiful fresh herbs to spice up your food. If you have a big greenhouse, you can even grow a lemon tree. We’ll give you some examples of herbs, vegetables, and fruits that will grow indoors!

Herbs and spices:

  • Basil
  • Parsley
  • Mint (be careful as this plant tends to grow quickly and might smother your other plants)
  • Oregano
  • Thyme
  • Rosemary
  • Chives

Lots of vegetables are suited for indoor growing:

  • Carrots
  • Hot peppers
  • Lettuce
  • Tomatoes
  • Spinach
  • Radishes
  • Cucumber
  • Avocado

What about some homegrown fruit?

Try growing these fruits inside:

  • Strawberries
  • Oranges
  • Lemons

Other tips to enjoy your indoor greenhouse to the fullest

As your plants won’t benefit from natural soil, it’s important to make sure that the soil you use has plenty of nutrients. Especially when your plants have just started growing it’s a good idea to use extra fertilizer about once a month.

The temperature in your greenhouse should be around 70-75 degrees Fahrenheit. The easiest way to make sure the temperature doesn’t get too high is by placing a thermometer inside your greenhouse. When the temperature gets too high you can either move your greenhouse away from the sun for a little while or open up the top or sides to let some air in.

Make sure you water your plants sufficiently, as plants need both sun and water to grow. Depending on which crop you are growing, check how much water it needs and pay attention to how dry the soil is. During summer your plants might need more water when your house is warmer, so check the greenhouse temperature to give your plants the best chance of survival!

If you’re more of a flower person, indoor gardening can also add beautiful touches to your decor with growing pretty blooms like petunias and orchids.

Some people might assume that gardening is not an option for them because of the restrictions of their property.

Maybe you have animals invading your area or have poor soil. Or maybe you live in a climate where it is difficult to grow plants outside.

Luckily, there are options for gardening for people living in any situation.

Indoor greenhouses are a solution.

Benefits of indoor greenhouses

An indoor greenhouse can provide the optimal environment for growing plants of your choice within the confines of your home.

Are you interested in the idea of owning a mini indoor greenhouse, but think you might not have the space for one?

Let’s take a closer look and answer some FAQs about indoor greenhouses.

Growing plants in an indoor greenhouse

Why an indoor greenhouse?

Before we get into the details of setting up a mini indoor greenhouse, let’s consider the benefits of installing one.

An indoor greenhouse is a great option for folks who have limited options for growing crops outside.

For instance, you might have a short growing season or might not get good light in your yard.

Then, an indoor greenhouse can come into play.

You can grow your own food without worrying about temperatures, humidity, and natural sunlight.

Indoor plants give out fresh oxygen, purifying the air within your space.

An indoor greenhouse is also ideal for folks who live in a small apartment or condo and don’t have space for a yard.

They make life more sustainable by reducing costs of frequent grocery trips for produce and fuel consumption.

Growing sensitive plants like orchids becomes easier in controlled environments indoors.

What can you grow inside an indoor greenhouse?

The size of your greenhouse will depend on what kind of plants you plan to grow.

For this reason, you should spend some time considering what you want to grow before you install the greenhouse.

There are some plants that grow better indoors than others.

In general, micro greens and herbs tend to be the most successful at growing indoors. However, because they are easy to grow, you may want to do those on your kitchen counter, and save other plants for the greenhouse.

Fruit-bearing plants do not grow very well indoors because they need exposure to wind and bees to get pollinated.

Indoor plants you can grow indoor greenhouses

  1. Cucumbers
  2. Tomatoes
  3. Spinach
  4. Swiss chard
  5. Lemons
  6. Oranges
  7. French beans
  8. Okra
  9. Onions
  10. Broccoli

Flowers that grow well in indoor greenhouses are gazanias, chrysanthemums, pansies, poinsettias, petunias, caladiums, salvia and geraniums.

Also, we recommend growing indoor plants from seeds, rather than transplanting plants you started outside.

This way, you won’t unintentionally bring in pests or vermin from outdoors.

Another way to prevent pests from coming into your home is to plant pest repelling plants, like marigolds.

How big should your indoor greenhouse be?

Really, there is no set size for your greenhouse.

The size of the greenhouse you choose depends on certain decisions you make about gardening.

When deciding how big your greenhouse should be, ask yourself these questions:

What are you planning to grow?

For instance, if you are growing a green like spinach or collard, you will need more room than for herbs like basil or parsley.

This is because their leaves will spread out more and demand space. This is also true of growing tomatoes in pots. They will grow large.

How much are you planning to grow?

If you plan to grow a just couple of plants, you won’t need much space.

Even a window sill might work. You may not need an indoor greenhouse.

How many different types of plants do you want to grow?

If you have more than one kind of plant, you may need to plan for soil rotation and their compatibility.

Also, keep in mind that plants need more space between them so that they get sufficient light.

If the plants you are growing do not need much space, you can choose a miniature greenhouse.

These can fit on a windowsill, or in a corner of your home.

If you are new to gardening, we recommend starting off smaller.

A smaller greenhouse won’t need as much care as a larger one and will be easier to maintain.

If you find that you enjoy the hobby, you can always purchase a larger one.

Good indoor greenhouse

To grow healthy plants indoors, take care of the following elements and you can grow miracles:

Greenhouse temperature

Ideal temperature helps a lot in growing healthy crops.

If the environment is too warm or too cold, crops could grow abnormally.

Wherever you place your greenhouse inside your home or not, make sure the temperature is regulated to be between 60-70 degrees Fahrenheit.

Some plants, however, grow in colder temperatures and will need an environment between 50 and 70 degrees.

Keep in mind that the glass of the greenhouse will make it warmer than it is within your home.

Make sure to place a thermometer inside the greenhouse so that you can accurately monitor the temperature.

Lighting for an indoor greenhouse

For the best results, you should place your greenhouse where it will get sufficient sunlight.

While artificial lights are available, they are not a complete substitute for natural sunlight.

That said, lamps can be used effectively to supplement sunlight in the winter months.

When you use a lamp, consider how the color of the light will affect heat.

For instance, white light will create more warmth than cool light.

If getting proper lighting is an issue, you can always choose plants that prefer low light.

More on choosing the correct lighting and shade system here.

Greenhouse water

Another necessity for plants is water.

Without proper watering, your plants can easily become dehydrated, dry out and die.

For indoor plants, room temperature tap water will work just fine.

You could also consider collecting rain water or melted snow to save water.

With that being said, make sure not to over water your plants.

Signs that you might be over watering your plants include the growth of fungus or mold on the soil, standing water or leaves with brown rotting patches.

You can also choose systems which water plants automatically and in correct amounts to save time and labor.

Greenhouse nutrients

When you grow your plants indoors, it is particularly important to make sure they have the nutrients and minerals they need to shoot up in height.

This is because your plants have limited soil, they will quickly draw out the nutrients from it.

We recommend fertilizing your plants monthly while they are in their early stages of growth.

In the winter months, they will not need as many nutrients.

Hydroponics is another great way to grow plants indoors with proper nutrients.

Installing the right indoor greenhouse for your needs

With these tips in mind, you can easily install your very own greenhouse, no matter what your space requirements are.

What are the ideal space requirements for an indoor greenhouse?

Before you decide on the spacing requirements for your greenhouse, you’ll have to choose a right location for your indoor garden.

The perfect location would be one which gets plenty of sunlight, like a south-facing patio door or window.

You’ll also need a spot with high natural humidity and temperature.

Once you have these factors accounted for, go ahead and think about the space requirements you’ll need.

Indoor Greenhouse Space Requirements

A good ratio to build your greenhouse is 3:1.

You can experiment with these figures to assemble an apt greenhouse.

You can grow plants indoors with something as small as a 20 x 20 inch mirror box on your coffee table!

This will be cozy enough for small apartments.

You can also recycle old windows into greenhouse boxes.

Flats are a great way to grow herbs and small plants.

With dimensions of 10 x 20 inches, you can place them on the ground or on an elevated desk.

Additional shelving above this desk can help you add plants on the wall above at no extra space.

For a beginner indoor grower, you’ll need at least 6×8 feet worth of space with an ideal dimension of 10×10 feet.

Another point to note is that the width of the greenhouse will determine how you place the benches and aisles.

For hobby growers, you’ll need widths of around 8 to 10 feet, scaling up to 12 to 20 feet.

Widths for commercial growers will range from 20 feet on wards.

In some greenhouse kits, the dimensions mentioned would be including the thickness of the walls.

So the inner width and height available for plants would be lesser than the size mentioned on the kit.

You will have to clarify this with the manufacturer.

The bigger the greenhouse, the greater will be the cost associated with it.

You’ll have to account for this as well.

Also, as the plants grow bigger, you will need larger pots and shelving areas to hold them.

Consider this too when planning for your greenhouse.

Greenhouse equipment must be stored nearby.

You’ll have to think of places to store gloves and tools as well when establishing your greenhouse.
