Ever wish you could start planting earlier in the spring, keep growing later into the fall, or give your favorite plants a little extra protection from unpredictable weather?
The 10' x 12' Backyard Greenhouse Kit makes it easier to create a dedicated growing space right at home.
With 120 square feet of growing space, a sturdy galvanized steel frame, durable 6-mil greenhouse film, and convenient ventilation through included roll-up sides, this compact greenhouse offers a practical way to extend your growing season.
It also includes a scissor-style metal door, giving you an accessible entry point without needing to purchase a separate door kit.
Whether you're growing vegetables, starting seedlings, or building your first backyard greenhouse, this kit combines professional-style growing features with a manageable size for residential properties.
The 10-foot-wide by 12-foot-long footprint provides approximately 120 square feet of ground area.
That's enough room to plan a variety of growing layouts, depending on your preferred beds, containers, and walking paths.
Consider using your greenhouse for:
Starting vegetable seedlings
Growing tomatoes, peppers, and herbs
Protecting tender plants during seasonal transitions
Extending your spring and fall growing seasons
Creating raised-bed growing areas
Growing flowers and specialty plants
Maintaining a dedicated backyard gardening space
The greenhouse has an inside height of approximately 7 feet 11 inches, providing comfortable standing room near the center and additional space for taller plants.
Not every property has room for a large commercial greenhouse.
This kit is designed with a manageable footprint that can fit into many residential backyard layouts.
At 120 square feet, it falls below some commonly used accessory-structure size thresholds.
However, HOA approval, zoning rules, setbacks, and permit requirements vary by location. Always confirm local requirements before purchasing or installing.
The greenhouse features a frame constructed from 1⅜-inch galvanized steel tubing.
Galvanized steel provides corrosion resistance and a durable alternative to untreated wooden framing.
The kit includes three pre-bent steel hoops and a ridge pole that connects the structure.
Its pre-bent components help simplify installation and reduce the amount of measuring and fabrication required.
The kit includes a scissor-style metal door, giving you a convenient entrance to your growing space.
Because the door is included, you won't need to source a separate door kit for the standard configuration.
The door provides access for everyday tasks such as watering, planting, harvesting, and tending your crops.
Ventilation is one of the most important parts of managing a greenhouse.
On sunny days, temperatures inside a covered growing structure can rise quickly.
The included roll-up side kit allows you to open the sides for increased airflow when conditions permit.
This can help you:
Release excess heat
Improve air circulation
Manage humidity
Create a more comfortable growing environment
Adjust ventilation as outdoor conditions change
Remember that greenhouse temperatures still require monitoring, especially during warm weather.
The greenhouse includes enough 6-mil greenhouse plastic to cover the structure.
The manufacturer lists the film with a four-year rating.
The covering allows sunlight into the greenhouse while helping create a protected environment for plants.
Actual film lifespan depends on weather exposure, installation, and ongoing maintenance.
You don't need to be a professional greenhouse builder to put this kit together.
The manufacturer provides step-by-step printed instructions and a video assembly guide.
Most installations are estimated to take one to two days with two people, assuming the site is prepared.
A single person may be able to complete the project with additional time, although assistance is recommended when handling larger components and greenhouse film.
The included door and roll-up sides may add to assembly time.
The standard kit includes:
(3) Pre-bent steel hoops made from 1⅜-inch galvanized tubing
(1) 1⅜-inch galvanized steel ridge pole
Ground post driver
36-inch ground stakes
6-mil greenhouse plastic with a four-year manufacturer rating
Required hardware and connectors
Scissor-style metal door kit
Roll-up side kit
