Planning Your Backyard Greenhouse

Choosing the Location
Picking the right spot for your greenhouse is key to its success. You want to make sure it gets plenty of sunlight—at least six hours a day. A south-facing location works best for maximizing sunlight exposure. Avoid placing it near tall trees, fences, or buildings that might cast shadows.
Think about wind exposure too. A spot sheltered from strong winds will help maintain a steady temperature inside. If your yard is prone to gusts, consider adding a windbreak like a hedge or fence. Also, avoid areas where frost tends to settle, as this can harm your plants. For extra insulation, you can protect the north side of your greenhouse to reduce heat loss. Lastly, choose a spot that complements your garden and adds to its overall aesthetic.
Selecting the Greenhouse Design
When it comes to design, you’ve got options. A-frame greenhouses are simple and budget-friendly, while hoop houses are lightweight and easy to build. If you’re short on space, a lean-to greenhouse that attaches to your home or garage could be perfect.
Think about what you’ll grow and how much space you’ll need. If you’re planning to grow tall plants like tomatoes, make sure the design allows enough headroom. For smaller plants or seedlings, a compact design will do the trick. Keep it simple if this is your first DIY greenhouse project. You can always expand or upgrade later.
Sourcing Affordable Materials
Building a greenhouse on a budget means getting creative with materials. Plastic is a popular choice for covering because it’s lightweight, flexible, and affordable. You can find plastic covers for as little as $200 for smaller greenhouses. However, keep in mind that plastic may need replacing over time.
For the frame, consider using PVC pipes or repurposed wood. Old windows or sliding glass doors can make excellent walls, giving your greenhouse a rustic charm. Check local hardware stores or online marketplaces for deals on materials. You might even find free or low-cost items through community groups or recycling centers. Using recycled materials not only saves money but also makes your project more eco-friendly.
How to Build a Greenhouse

Constructing the Frame
Building the frame is the backbone of your greenhouse structure. Here’s how to do it step by step:
Build the Foundation: Start by clearing the area of topsoil. Level and compact the dirt to create a stable base. Use landscaping timbers to form a mini retaining wall for added support.
Build the Side and Back Walls: Use pressure-treated 2x4s for the bottom plates and cedar 2x4s for the top plates. Mark where the studs will go to ensure even spacing.
Frame the Front Wall: Assemble the front wall, leaving space in the center for the door. This will make it easier to install later.
Anchor the Walls: Secure the walls to the ground using bullet anchors. This step ensures your greenhouse can withstand wind and weather.
Repeat Parts With a Template: Create a template for cutting rafters and assembling trusses. This saves time and ensures uniformity.
Assemble Gable Walls: Follow the same process as the trusses. Make sure collar ties and cripples fit properly for added stability.
Using a lean-to greenhouse design? Attach the frame directly to your home or garage for extra support and insulation. For a DIY approach, PVC pipes are a lightweight and affordable option.
Adding the Covering
Choosing the right greenhouse covering is crucial for durability and cost-effectiveness. Here’s a quick comparison of popular options:
Material Type | Durability | Cost-Effectiveness |
---|---|---|
Glass | Can break but lasts many years | More expensive upfront |
UV-resistant polycarbonate | Durable, retains heat, less expensive than glass | Warranties up to 15 years |
Plastic sheeting | Lightweight, inexpensive, less durable | Needs replacement once a year |
For a budget-friendly option, greenhouse plastic sheeting is a great choice. It’s lightweight and easy to install. Simply drape the plastic over the frame and secure it with clips or staples. If you’re using a greenhouse kit, follow the manufacturer’s instructions for attaching the covering.
Installing Doors and Ventilation
Proper doors and ventilation keep your greenhouse functional and your plants healthy. Here are some best practices:
Aspect | Best Practice |
---|---|
Fan Sizing | Fans should provide one volume air exchange per minute for summer ventilation. |
Fan Location | Install fans on one end wall with louvers on the opposite end for effective air movement. |
Maintenance | Motorized vent controllers should be cleaned and lubricated several times a year. |
Vent Adjustment | Vents should close evenly and tightly before the heating season to prevent heat loss. |
Intake Area | The intake louver area should be at least 1 1/4 times the fan area for adequate air supply. |
Thermostat Control | Use two-stage thermostats for energy savings and better control of temperature. |
Install a sturdy door that seals tightly to maintain temperature control. For ventilation, place fans on one end of the greenhouse and louvers on the opposite side. This setup ensures proper airflow. If you’re using a lean-to greenhouse, consider adding vents near the roofline for natural heat escape.
Cost-Saving Tips for Building a Greenhouse
Using Recycled Materials
Recycled materials can save you money and make your greenhouse more eco-friendly. You’d be surprised at how many items you can repurpose for this project. Here are some creative ideas:
