7 Frequently Asked Questions

#1. How much do Greenhouse Kits Cost?

greenhouse 2

A greenhouse can range from a few hundred dollars to a few thousand dollars depending on size and frame material.

Typically, greenhouse kits will cost about $25 per square foot.


#2. What Should I Look for When Buying a Greenhouse Kit?

Not all greenhouses are created equally.

Landscape layout, Cost, Size, Frame Material, Insulation, and Window Panels are critical factors you should have an understanding of before purchasing one of the Best Greenhouses on this list.

A) Landscape Layout

Before purchasing one of the Best Greenhouses in this article it is first important to determine your landscape layout and if a greenhouse is the right fit for you.

Before you decide where to put your Greenhouse it is critical that you have an understanding of your city’s zoning requirements.

Can you have a greenhouse? Are there size regulations? Does it have to go on a specific part of your property? Does it have to be a specific distance from your neighbors?

These are all great questions to ask.

I would then recommend finding an area on your property that will get at least get 6 hours of sunlight all year.

If you live in a shaded area it may not affect gardening in the summer, but could greatly impact what you can grow in the winter.

In addition, there may be a benefit of building your greenhouse near an electrical outlet or water pipes/supply.

Finally, you want to prepare the site where your greenhouse will be built.

You may need to clean the area. You may also need to remove rocks, wood, or other debris.

When preparing your site there may be a benefit of having a concrete foundation poured first. This will greatly increase the insulation in the winter.

B) Greenhouse Costs

Another important factor of owning a greenhouse is cost.

Typically, the larger the greenhouse kit the more expensive it will be.

Greenhouse kits typically range from a couple of hundred dollars to several thousand dollars.

If you want the best price, I recommend buying a greenhouse kit through: Amazon

Also, it is important to remember that there may be other costs associated with your greenhouse.

Will you need any additional materials to build it? Will you need to clear land? Pay someone to build it? If so, then factor those costs into the total cost.

In addition, what will the maintenance cost?

Typically, you won’t have to make repairs in the first ten years of your greenhouse. Later in a greenhouse life, you may need to put additional money into it for repairs.

Also, don’t forget to factor heating your greenhouse and providing water to it in the total costs.

I once heated my greenhouse in January for an entire month straight and my electric bill was three times as expensive as before!

C) Greenhouse Size

Typically, greenhouses come in three sizes; small, medium and large.

Small greenhouses are usually 6 feet by 2 feet.

Medium greenhouses are usually 10 feet by 12 feet.

And large greenhouses are 10 feet by 20 feet.

When determining the size of the greenhouse you should buy I recommend first determining how much space you have in your yard.

After determining how much space is available, I then recommend determining how much room your plants will need.

Finally, determine if you will ever have an interest in expanding the number of plants you will have in your greenhouse.

If you foresee needing more space in the future it may make sense to start with a medium or large greenhouse.

D) Frame Material

greenhouse 1

Frame material may be one of the most important factors to consider when purchasing a greenhouse.

The type of frame material you use will directly impact how durable and long-lasting your greenhouse will be.

Aluminum Frame

Aluminum frames are the most common type of material used for the best greenhouses. It is light, easy, and cheap.

Wood Frame

Wood Frames are some of the most durable and best insulating frames for your greenhouse. In addition, they are typically easy to set up and are relatively inexpensive.

Plastic Frame

Plastic frames are some of the cheapest frames you can find for greenhouses. While they are not the most durable, they do provide excellent insulation.

Steel Frame

If you want the most heavy-duty frame for your greenhouse then go with a steel frame. Steel typically low cost and is reasonably easy to set up.

PVC

PVC frames are almost as cheap as plastic and provide just as good of insulation. This type of material is also great for cold frames that you wish to easily move. The only downside is that they are typically not strong or durable.

Solexx

Solexx is composite, which is a type of hybrid material of aluminum, plastic, and PVC. It provides excellent insulation but is very expensive.

Window Panels

Another factor that you should consider when building or purchasing a greenhouse is what type of window panels it comes with.

Clear panels will give you more sunlight. This is great for starting seeds as they need more sunlight.

Twin aka multi-walled panels is great for growing mature plants. It diffuses sunlight, which is perfect to help plants steadily grow.

The size of the window panels is also important. 

The bigger the panel, the more sunlight your plants will receive. Again, more sunshine is perfect for seedlings. Less sunlight is typically needed for mature plants.


#3. How Do You Heat Your Greenhouse in the Winter?

greenhouse 4

Having a greenhouse is a great way to extend the gardening season. Having one of the best greenhouses increases your likelihood of success.

But having the best greenhouse does not always guarantee success when it comes to heating your greenhouse in the winter.

Below, is a list of ways you can heat your greenhouse cheaply in the winter:

  • Use a heater
  • Add insulation
  • Add heat-absorbing barrels
  • Double layer your plastic
  • Use Compost
  • Add extra insulation at the north side of your greenhouse
  • Build your greenhouse partially underground
  • Add burlap


#4. What Type of Greenhouse Should I Build?

The type of Greenhouse Kit you should buy depends solely on your landscape, your city ordinances, and what you would like to build.

You can build a free-standing greenhouse, a gutter-connected greenhouse, or a portable greenhouse.


#5. Are Portable Greenhouses Good?

Portable Greenhouses are great options for someone who wants a greenhouse on their patio or deck.

This type of greenhouse provides gardeners with the ability to quickly access their plants from the house. This is also a great option for someone who wants to expand or move their greenhouse.

Portable greenhouses though do not prevent freezing and damage to plants as well as stationed greenhouses.


#6. What are the Benefits of Owning a Greenhouse?

There are many benefits to owning a greenhouse. Some of the benefits include:

  • Longer Growing Season
  • A wider range of plants can be grown
  • Less worry of pests or insects
  • Less worry about weather
  • Environmentally Friendly
  • Energy Conservation


#7. How Long Do Greenhouses Last?

As described above, greenhouses longevity will mainly depend on the materials you used and the climate you live in.

Expect on average for your greenhouse to last between 15 to 25 years, although some greenhouses can last a lifetime.

Greenhouses in climates that have mild winters and summers will tend to last longer than those that are exposed to extreme cold or heat.

Also, greenhouses that are made of steel, aluminum, and certain types of finished wood should last longer no matter where you live.
