13 Cheap DIY Greenhouse Plans for the Budding Gardener

Creating a greenhouse doesn’t have to break the bank. With a dash of creativity, a bit of determination, and some basic tools, you can craft a greenhouse that meets your gardening needs without draining your wallet. Below, we’ve compiled 13 affordable DIY greenhouse plans that can help you cultivate plants year-round while making the most of your gardening space.

1. PVC Pipe Greenhouse

Using inexpensive PVC pipes, you can construct a simple and effective greenhouse. This plan involves building a frame with the pipes and covering it with clear plastic sheeting for sunlight. This lightweight option can be moved easily and set up in various locations.

2. Wood Pallet Greenhouse

Repurposing wooden pallets is both environmentally friendly and budget-conscious. With a few pallets, you can create a small greenhouse by standing them up on their sides, forming a rectangular shape, and using plastic sheeting for roofing. This design offers great ventilation and allows for easy access to your plants.

3. Cold Frame Greenhouse

A cold frame is an excellent, low-cost alternative for extending your growing season. You can build one from reclaimed wood and old windows, providing a heat-trapping enclosure for seedlings and plants. This plan is perfect for smaller gardens and can be easily constructed in a weekend.

4. Hoop House

Using rogue materials like plastic sheeting and a series of hoops made from wire or flexible piping, a hoop house can be erected quickly. This low-cost structure is perfect for protecting plants from frost while allowing ample sunlight.

5. Mini Greenhouse with Shelving

For those with limited space, a mini greenhouse can be a brilliant solution. You can create a shelving unit out of wood or metal and cover it with plastic sheeting. This plan allows you to grow herbs, cuttings, and small plants in a compact and mobile structure.

6. Old Window Greenhouse

Turn old windows into a charming greenhouse! This project requires skill in carpentry, but the results are rewarding. By attaching multiple windows together, you can form the walls and roof of your greenhouse, creating a unique and attractive design that recycles materials.

7. Bicycle Frame Greenhouse

If you have an old bicycle frame lying around, consider upcycling it into a quirky greenhouse frame. Drape plastic sheeting over the frame, ensuring plenty of light can reach your plants while providing them wind protection.

8. Tarp Greenhouse

Using a simple wooden or metal frame, drape a heavy-duty tarpaulin to create a quick and easy greenhouse. This structure can be easily erected and disassembled as needed while providing excellent insulation.

9. Raised Bed Greenhouse

If you have existing raised beds, consider constructing a small greenhouse using a lightweight frame covered with plastic or netting. This option allows for growth right in your garden while maintaining a microclimate to promote healthy plant development.

10. Portable Cart Greenhouse

For those with limited outdoor space, a portable cart greenhouse can be an ideal solution. Build a small wooden cart with shelves and cover it with plastic. This allows you to move your plants around as needed, soaking up the sun or providing shade as required.

11. Concrete Block Greenhouse

Using concrete blocks can create a sturdy base for your greenhouse. Stack them in a rectangular shape and use reclaimed materials like plastic sheeting or glass for the roofing. This solid structure is ideal for enduring harsh weather conditions.

12. Greenhouse Tunnel from Cattle Panels

Cattle panels can be bent and shaped into an arch, providing a framework for your greenhouse. Covered with plastic sheeting, this design offers great stability and ample growing space for larger plants to flourish.

13. Shed Conversion Greenhouse

If you have a small shed that’s seen better days, consider converting it into a greenhouse. Replace the roof with clear plastic panels and add vent windows for airflow. This option will keep your plants safe from pests while utilising existing structures.


Conclusion

Building your own greenhouse doesn’t need to be an expensive project. With these 13 plans, you can find an option that suits your gardening needs and budget. Whether you want to grow herbs, vegetables, or beautiful flowers, a DIY greenhouse can enhance your gardening experience and extend the growing season.
