Average Greenhouse Weight (with 9 examples)

Knowing the average greenhouse weight is crucial when building a foundation for a greenhouse. Also, if you want to move a structure around, you need to know how much does a greenhouse weigh. To make it easier for you, I put together a list of popular hobby greenhouses weights.

Generally, an average aluminum and polycarbonate 6 ft x 8 ft hobby greenhouse weighs around 74 lbs or 34 kg. If it comes with twin-walled polycarbonate roof panels, the weight is around 90 lbs or 41 kg. A wooden greenhouse with glass panels weighs more.

Not gonna lie but it took me ages to come up with a comprehensive list of the most popular hobby greenhouses and their weights. Hope that you find this information helpful and feel free to share it! Also, we will do some digging to find out why greenhouse weight is an important specification.

Greenhouse Weight By Size

  • 6 ft x 4 ft greenhouse – 68 lbs (31 kg)
  • 6 ft x 6 ft greenhouse – 83 lbs (37.5 kg)
  • 6 ft x 8 ft greenhouse – 90 lbs (41 kg)
  • 6 ft x 10 ft greenhouse – 99 lbs (45 kg)

Considering greenhouse structure dimensions, they are quite light and easy to handle. Hence, assembling and moving them around is not a problem. Also, it is possible to move it around in the future. However, most likely you will need to reassemble it if you are moving to a new home.

How much do greenhouse materials weigh?

As you know a greenhouse frame can be made of wood or aluminum. A good frame is sturdy and rigid withstanding strong winds and severe weather conditions. The weight of the greenhouse structure is directly linked to how vulnerable it is to wind damage.

For example, aluminum frame is a very popular material for any greenhouse structure. It is strong and at the same time very light. In comparison to other frame materials, it has a higher strength to weight ratio.

Moreover, it doesn’t require an additional coating in comparison to wood frame which results in higher maintenance routine. Also, worth to mention that aluminum frame won’t warp, rot or rust and it is nontoxic. Finally, it is very easy to clean and you can even paint it (but I wouldn’t recommend it).

Pros And Cons Of Polycarbonate Greenhouse

Apart from the frame, greenhouse consists of the cover panels too. Back in the days glass was a popular choice, but now polycarbonate seems to take over. However, I wouldn’t rush to switch from glass to polycarbonate straight away. Here is why:

Polycarbonate is very lightweight and flexible, so can be prone to wind damage. Glass panels can add weight to the whole greenhouse structure!

Wait, what? Yes, the wind can bend and flex the polycarbonate panels so they can pop out of the frame. In comparison, glass covering adds weight to the greenhouse frame improving the rigidity of the whole structure. When choosing a glass glazing, make sure to opt for toughened safety glass which doesn’t break.

Why Structure Weight is important?

First, knowing greenhouse weight helps you to decide what foundation you need to build. Secondly, if your greenhouse is lightweight, you will need to build a heavier base so that greenhouse doesn’t blow over. Finally, the weight of the greenhouse can give you an idea on what load it can withstand.

You don’t need to know the greenhouse weight precisely to pounds to make up your mind about the foundation. For a Victorian greenhouse made of glass and wood a perimeter base is not enough. You would need to build a solid concrete or brick base, for example.

To keep a greenhouse from blowing away, simply sitting it on the ground is not enough. If your structure doesn’t come with the base, I recommend building one or securing it to the ground with the anchor kit you can buy on Amazon. It secures the structure to withstand snow and wind load.
