Build your Own Green House: Planning Build your Own Green House: Planning

For an ardent gardener having their own greenhouse is a dream come true. Tropical plants can be grown all year, seeds can be started in the middle of winter and best of all there is no end to gardening season. While many gardeners dream of having their own greenhouse, only a few ever actually achieve their dream and that's a pity. Even though building their own green house is a significant amount of work, it isn't beyond the skills of many DIY'ers. If having your own greenhouse is one of your dreams, here's some thoughts on how you can actually achieve your goal.

Size

Experienced gardeners say its best to start with the largest greenhouse you can fit into your yard, since whatever size you start with you will find it will quickly seem too small. Building a large greenhouse is easier and less expensive than trying to expand an existing building.

Location

When deciding where to position your greenhouse keep the location of the sun in mind. Since you want the sun to shine into your green house, locate it so it won't be shaded by an overhanging tree, your house or any other building on your property.

Try to align your greenhouse so the longest side faces south, to maximize exposure to sunlight in the winter. The downside to this alignment is you may need to install shades to protect your plants from the heat of the summer sun.

Kits

Greenhouse kits are commonly available at building supply centers and on line in many sizes, shapes and different materials. Since a kit provides all the piece parts including doors and hinges, all designed to fit together, it will save you a lot of the cutting and measuring necessary to put your greenhouse together, However, kits are usually more expensive than a green house you build from scratch and you are still the person who will actually put the pieces together.

Plans

If you decide you would like to build your greenhouse from scratch, plans and designs are inexpensively available on line or from home and garden centers. Building it yourself will also give you the option of choosing materials and you could even use recycled materials for much of the structure. All the necessary components (including windows, fans and watering systems) are commonly available at home and hardware stores so they are easy to include in your structure.

Foundations

Some small home greenhouses are simply built on the ground without any foundation, however, for a more permanent structure some form of a foundation (gravel or concrete) is more appropriate.

Pea gravel provides an inexpensive floor and foundation for a home greenhouse. Simply remove any sod, dig down 3 or 4 inches and fill in the area with pea gravel. A pea gravel greenhouse floor won't get muddy or slippery when it's wet and will actually absorb any water spills, giving you a floor that is safe to walk on at all times.

For a large, permanent structure, a concrete floor/foundation is a better choice. Installing a concrete floor is a job you might consider contracting out, since it requires digging down about a foot, installing then packing 3 or 4 inches of gravel, topped by 2 inches of sand and finally pouring a concrete slab--Altogether a lot of work and most of us don't have the digging, hauling and packing equipment necessary to do the job.
