Below are free greenhouse plans built with 2×4’s, PVC pipes, and cattle wire. You can also use old windows, glass doors, and such. Start by measuring your material and drawing plans to incorporate the material into sturdy frames.
If you are using wood for the frame it should be painted or stained so it can last longer. The type of wood that is ideal to use is redwood, cedar, or pine.
Start planting early and late into the colder weather by building your own greenhouse. Check out the plans below for ideas.
A greenhouse doesn’t need to be large. You can fit many plants by building tables and plenty of shelves. The most common size that can accommodate lots of plants is an 8×10 greenhouse.

Greenhouses, a.k.a hot houses, have been used throughout history, the first ones being recorded in ancient history for growing vegetable and fruits that were not indigenous to their areas. They were thought to be only for the rich as they were heavy structures made of glass and required a lot of maintenance and upkeep.
Now greenhouses are made to fit any size or budget. From small portable plastic walled structures to the huge impressive metal and glass structures of old, greenhouses are used by everyone from the private garden novice to the mass market producers.
No matter your level of gardening or reason for wanting to grow your plants or seeds, greenhouses should play an important part in your process. They are beneficial to any garden regardless of size or function; allowing you to get a jump on the growing season by starting your seeds in a warm environment before placing them in the ground. This gives you a longer growing and producing season. Also, many seeds need particular environments in order to survive and thrive. With our fluctuating weather patterns this is not conducive to proper growth. Greenhouses allow you to grow and produce seeds that are usually not allowed to grow in your area due to temperatures in weather.
They work to absorb the heat from the sun then disperse that heat to the plants and soil throughout the cooler days and nights during winter and spring. This allows for your seedlings and finicky plants to thrive while the rest of nature is covered in frost. Greenhouses need to be placed in a sunny spot in your garden to soak up their needed rays.
Greenhouses are made to fit any garden type. No matter your conditions or space allowed for growing your garden, there is a greenhouse for you to fit you budget and lifestyle. Greenhouse kits can be bought online, or they can be built. Greenhouses range from very simple to very complex depending on your needs:
