Factors Affecting the Cost of Building a Mini Greenhouse
To get a clear idea of how much it will cost to build a mini greenhouse, you need to consider a few different factors. The cost can vary significantly depending on the size, materials, and features you want to include. Here’s what you need to think about:
1. Materials
The type of materials you choose for the frame, covering, and foundation will greatly affect the overall cost. There are options to suit different budgets, and each material has its own pros and cons.
- Frame Materials: Wood, PVC, or metal are the most common options.
- Covering Materials: Polyethylene film, polycarbonate panels, or glass are popular choices.
- Foundation: Gravel, concrete, or a wood base.
2. Size and Dimensions
Naturally, the size of your mini greenhouse will impact the cost. The larger the greenhouse, the more materials you’ll need and the higher the cost will be. However, even small mini greenhouses can be surprisingly affordable depending on the materials used.
3. Location and Climate
Your location also influences the overall cost. If you live in a particularly windy or cold area, you may need to invest in stronger materials and better insulation, which will add to your total costs.
4. Additional Features
Do you want extra features like built-in ventilation, shelving, or heating? These can increase the cost but add a lot of functionality to your greenhouse.
5. Labor (DIY vs. Pre-Made Kits)
Are you planning to build the greenhouse yourself or buy a pre-made kit? DIY can save you money, but pre-made kits are more convenient and often come with everything you need to get started.

As you can see from the table, the cost of materials can vary widely depending on your choices. For example, choosing metal for the frame and glass for the covering will cost more than opting for PVC and polyethylene.
Frame Materials
- Wood: Wood frames are strong and look natural in your garden. However, they can be more expensive and require regular maintenance to avoid rotting.
- PVC: PVC is a budget-friendly option that’s easy to work with, but it’s not as durable as wood or metal.
- Metal: Metal frames are the most durable but can be more costly. They’re perfect for those living in areas with harsh weather conditions.
Covering Materials
- Polyethylene: This is the most affordable option for covering your greenhouse. It’s easy to install but may need replacing after a few years.
- Polycarbonate: Polycarbonate panels are a step up in terms of quality and insulation. They’re more durable than polyethylene but also more expensive.
- Glass: Glass provides the best light transmission and looks great, but it’s the most expensive option and can be fragile.
Foundation Options
- Gravel: Gravel is inexpensive and provides good drainage, but it may not offer as much stability as concrete.
- Concrete: A concrete foundation is strong and long-lasting, though more expensive and labor-intensive to install.
- Wood Base: A wood base can be a simple and affordable option, but it may not last as long as concrete.

Arsalan is my friend who is always loved gardening, but the weather in his area wasn’t always ideal for growing plants year-round. That’s when he decided to build a mini greenhouse in his backyard.

He used PVC pipes for the frame, which cost him around $50, and covered it with polyethylene film for about $40. For the foundation, He went with a simple gravel base, which only cost about $30. In total, his mini greenhouse cost me less than $150 to build, and it has been a game-changer for gardening. He can now grow vegetables and herbs even in the colder months, and the whole process of building it was both fun and rewarding.
