Why Should I Get A Small Greenhouse?

Small Glass GreenhousePin

A greenhouse is a must-have for severe gardeners as it allows for all year gardening. Greenhouses are no longer a status symbol or only for people with enough land to build one.

There are now prebuilt models, kits for those who aren’t able to build one from scratch but still want to put it together, and variations of the greenhouse style that makes it work for any and every type of household.

Greenhouses don’t just expand the growing season but make it possible for you to grow anything without having to worry about the outside climate.

Want to grow tropical fruits; the greenhouse can be built to fit those specifications. Try your hand at cactus and succulent growing; that can be arranged.

There is no limit to the possibilities, and no matter what your location is, you can grow what you want, when you want.

Other Benefits Of Greenhouse Gardening

You Can Pick Up Pesticide-Free Vegetables

Because the greenhouse is enclosed it allows you to grow organically and without chemicals if you so choose. Insects and animals cannot enter the greenhouse, so you also don’t have to worry about anything eating your plants.

Nothing better than eating it straight from the vine and this lets me do that without having to worry about chemicals.

Stable, Steady, And Regular Gardening

Not only are you paying less because it is a much smaller size than larger greenhouses, but the smaller size means less cost to maintain your chosen climate.

If you want to create a tropical environment in a very cold place, you will have to pay to heat it, and that can be costly in larger greenhouses.

Solar-powered options are not yet available to heat the inside of the greenhouse, and personally, I cannot wait until that becomes an option as it saves even more money.

Easy Installation

Whether you choose a kit or a pre-assembled greenhouse, their smaller size allows you to not only install it without hassle but choose where you want it to go. From patios to backyards and everywhere in between, the smaller sizes accommodate any home.

Being a renter, I much appreciate the flexibility so I can still garden year-round without having to worry about my landlord disapproving.

Easier Maintenance

Sadly as plastic ages and time go on algae grows and what was once clear becomes opaque to UV damage. This means replacing plastic will be necessary every few years.

The smaller the size, the less plastic needs to be replaced and it is much easier to do so. The smaller size makes it more stable and less susceptible to collapses.

No Permits Needed

Unlike a large buildings, smaller greenhouses do not require building permits. Hassle-free and as simple as bringing it home and putting it up, small greenhouses have become my new preference.

No Wasted Produce

Unlike larger greenhouses that allow for massive hauls, the smaller size will enable you to grow what you will use while not having the extra go to waste.

Grow what you will use and don’t worry about rushing to get things canned or eaten before they go bad. Smaller amounts at a time still allow me to cut down on the grocery bill, but I don’t feel so overwhelmed or rushed.

What Should You Consider In A Greenhouse?

Two Men Gardening In Small GreenhousePin

There are many types of materials to choose from when it comes to greenhouses of any size and knowing which ones are best in specific situations.


There are four types of greenhouse temperatures: Cold house, cool house, warm house, and hot house.

Cold houses: These greenhouses are designed to have no additional heating source other than the actual enclosed space. They are ideal for the spring and fall to help extend the growing season and give crops more time to grow. But because it has no added heating the temperature inside can go below zero.

Cool houses: They are designed to maintain greenhouse temperatures above freezing. While they aren’t ideal for many plants, the ones that can survive freezing weather will have no problem in this type of greenhouse.

Warm houses: These are the most popular greenhouses as they support a comprehensive range of plants. The temperature usually hovers around 55 degrees Fahrenheit and plants that can withstand the cold can also be placed inside without issues.

Hot houses: The hot dwellings are designed to support tropical plants and are heated to stay above 60 degrees Fahrenheit.

They must have supplementary heating sources to support these plants, and you must consider the other plants you put into the greenhouse and make sure they can handle the heat and humidity.

These types of greenhouses also require more frequent maintenance as they can grow algae on the plastic quite easily.

How Large A Greenhouse Will You Really Need?

The greenhouse can range in shape and placement. There are free-standing greenhouses as well as supported greenhouses that lean against walls or buildings. Other styles can include A-frames, lean-tos, domes, gothic, and Quonset.

Options For Framing Material For A Greenhouse

Small Aluminum GreenhousePin

The types of materials for a greenhouse will determine how your plants go so you should consider what you want to grow and how each material will help or hinder their growth.

Clear Panels

Clear panels are ideal for seedling preparation for transplanting into the outside garden. The clear panels let in direct sunlight and can energize your plants and boost their growth rate.

Opaque Panels

An opaque panel is needed for plants that will grow to maturity in the greenhouse. This is because the opaqueness of the panels most closely mimics photosynthesis.

If you have no desire to move your plants to outside, this will help to give them what they need without giving the plants too much direct sunlight.

Wood Frame

Wood is strong enough to hold any glazing material but will wear out over time and is susceptible to rot.  

If you are choosing this type of frame, it will require yearly maintenance and proper drainage.

They are heavy with adequate anchorage and make it very hard to blow over. They are also easier to personalize with shelving and attachments.

Aluminum Frame

Aluminum is very durable and rustproof but is also very lightweight. They are the ideal material for first-time greenhouse owners and are easy with little to no maintenance involved.  

Aluminum is also a good conductor of heat, so it helps keep your greenhouse warm without having to pay for extra heating.

Plastic Frame

Small Greenhouse Plastic FramePin

Plastic is the most inexpensive option but comes with the downside of being incredibly lightweight and easier to blow over. They also don’t conduct heat as well as their metal counterparts.

To keep the plastic frames in place, they are often anchored by steel frames so consider the quality of what you are getting and how it will handle the climate where you are.

Steel Frame

Steel is extremely heavy and is typically used for permanent greenhouse structures.

They are difficult to maintain and work with so this is not my first pick for framing material, but if you live in a very windy location it may be better to pick steel for the added weight and anchoring it provides.

Glass Glazing

Although tempered glass has made vast improvements in preventing breakage compared to regular glass, it is still extremely heavy and hard to work with.

Freezing temperatures can crack and break the glass so while it has an aesthetically pleasing historic feel, it is not recommended for cold places.

Polycarbonate Glazing

This type of glazing is translucent rather than transparent, so the light comes through softer and more diffused. This makes it more useful for greenhouses and comes in a variety of thicknesses that help insulate the greenhouse as well.

This is my personal favorite, and while I highly recommend it, I don’t recommend the three-wall option as even though it adds greater insulation and protection against breaking, it makes it harder for light to get through to your plants.

Polyethylene Glazing

Greenhouse RoofPin

Polyethylene glazing for greenhouse covering is the least expensive option but it is still a viable one for smaller greenhouses and plastic frames.

Sadly this glazing material is susceptible to discoloration, fading, and yellowing and must be replaced every three to five years. It is also able to tear due to stretching caused by temperature extremes.

If you live in a very mild climate and only want a tiny greenhouse that would work on decks or porches, this will work for you.

But extreme weather conditions will wreak havoc on this material, and you will not have it long before needing to replace it.

Heating Options For The Greenhouse

Considering how much you have to spend will impact how much-automated control you can afford. For a lower-end heating option, I recommend a simple space heater.

Other more expensive options include forced air heat, radiant heat, steam, hot water systems, and soil heating.

No matter what option you choose make sure you plan ahead to ventilate your plants when introducing additional heat properly.  

Univent Automatic Vent Opener – Best Accessory To Add to the Greenhouse

A univent automatic vent opener lifts from 15 to 30 pounds – depending on the model. This is not a traditional-style greenhouse but rather an enclosure opener that adjusts your greenhouse vents depending on how hot it is.

It screws directly into the greenhouse frame and is well worth the money as it takes the hassle out of opening and closing vents and allows you to just focus on the plants.

As a shorter person, I know I appreciate not having to climb up on a stool every time I need to adjust the vents.


There are many varieties of greenhouses, and it is up to you to decide what you want, but I highly recommend these options and wish you the best of luck in your gardening adventures.
