7 Best Budget Greenhouse Kits

 

The common misconception is that you need to invest thousands of dollars to buy a greenhouse. Fortunately, this is not the case anymore; there are affordable greenhouse kits on the market today. 

Don’t waste your time trying to find an affordable greenhouse that fits your needs and budget. We have done all the research and compiled the best greenhouses on the market for different budgets. 

Let’s dive in.

Choosing a Greenhouse on a Budget

Choosing a greenhouse on a budget is not easy. You typically need to choose between size and durability. There are a few other key features that you should consider when purchasing your greenhouse:

  • Frame Material
  • Frame Reinforcement
  • Panel Material 
  • Panel Thickness 

Frame Material

The frame material is one of the most important features of a greenhouse. In the past, you often had to opt for a plastic or PVC greenhouse if you were on a budget. Fortunately, this is no longer the case; you can purchase a durable greenhouse with a metal frame on a budget. 

When choosing a greenhouse, those with metal frames are more expensive. The most affordable metal frame is aluminum. Aluminum frames are durable, lightweight, and inexpensive compared to steel or copper frames. 

If you want a more durable material such as steel, you will likely need to increase your budget. Greenhouse kits with steel frames are typically the most expensive. 

Panel Material 

The material of your greenhouse panels is an important feature of your greenhouse. Three common panel materials are used on most greenhouse kits: polycarbonate, tempered glass, and poly film. 

There are two materials that are often considered the most durable wall and roof panels are tempered glass and polycarbonate. Both these materials are great insulators and are also able to withstand heavy load capacity. 

Other common panel materials that are used include fiberglass, acrylic, polyethylene, and other poly-based plastics. These materials are not durable and I would not classify them as heavy-duty. Polycarbonate and glass panels typically have much higher wind resistance, load capacity, and durability than any other panel material. 

With that said, one of the most important aspects of polycarbonate or glass greenhouse panels is their thickness. The thickness will have a huge impact on how heavy-duty the panels are. 

Panel Thickness 

Panel thickness has a huge impact on the heavy-duty nature of your greenhouse panels. 

The fact is very simple - the thicker the panels the more heavy-duty they are. For example, simply opting for polycarbonate or glass does not guarantee your greenhouse is heavy-duty. 

For example, 0.7mm polycarbonate panels are not considered heavy-duty. These panels are relatively thin and don’t have a high load capacity or wind resistance. 

In general, there is a certain level of polycarbonate panel thickness and tempered glass thickness that offers some level of heavy-duty nature. 

Below are some guides when choosing panel thickness:

 Degree of Heavy-Duty Polycarbonate Panels Glass Panels
Low 4mm Twin-Wall Polycarbonate 4mm Double-pane Tempered Glass
Moderate 8mm Twin-Wall Polycarbonate 6mm Double-pane Tempered Glass
High 10mm Triple-Wall Polycarbonate 8mm Triple-pane Tempered Glass
