The first consideration is, of course, the roof material. The largest percentage of highest intensity sunshine comes during the late morning through early afternoon hours when the light strikes the roof. There are several choices for material and design when building a greenhouse that can affect how much of that sunlight energy enters your greenhouse.

Glass is traditionally one of the more popular choices for building a greenhouse. It transmits light well, it’s relatively easy to clean and it has excellent reflective properties that hold in the heat produced.

But glass is transparent, heavy, can be expensive and subject to breaking. Extreme temperature differences inside and out can cause spontaneous cracking. Accidentally bumping the glass can cause it to shatter.

As a consequence, and as the result of advances in materials over the last 20 years or so, many people end up building a greenhouse using plastic and composites for the roof. Plastics can be purchased that are completely transparent or only partly so, i.e. translucent. That helps control the amount of sunshine – helpful in climates that have long, summer hours of direct light and less cold winters.

Glass is still an option for those who want to invest in some system for shading the roof and several choices are available. There are inexpensive mechanical systems that use white cloth, bamboo, plastic shutters and others. For those with some money to spend, there are even systems that will sense the amount of sunlight entering and electrically open and close the shades!

Walls are the next major consideration when building a greenhouse. Here again, many are the traditional glass. When selected, they offer the same advantages and challenges as the roof, with the added proviso that they have to bear the weight of the roof. Most are embedded or alternated with some kind of load bearing rods, beams or other support materials.

A glass greenhouse can be a beauty to behold, but modern plastics and composites can also provide a lightweight, strong and attractive alternative. Some are even partially wood, aluminum and other materials, though these are more often used only on the lower half. There’s little point in building a greenhouse that doesn’t admit light – that’s just a shed!

Picking a material for the floor requires some thought, too. Wooden floors are inexpensive to build and replace as needed. But they don’t have the temperature control features offered by cement which traps heat and re-radiates it later in the day as the temperature cools. Choose something that offers good drainage and will last through several winters.

When choosing materials consider sunlight and heat control, the needs of the type of plants you intend to house and your own comfort. You’ll want something you can enjoy spending hours a day inside.

Many greenhouses have wooden floors. Relatively simple to construct, they can be made with 2 x 4’s or 1 x 6’s attached in a grid onto 4 x 4’s that sit on the ground. Spaced a half-inch apart, that can allow drainage. Weeds that tend to grow between the slats can be kept under control with any commercial spray. Even the average do-it-yourselfer can easily build a greenhouse floor in a day.

From that point, the skills level goes up a bit. Constructing greenhouse walls is a little tougher than it looks. Building a greenhouse wall perpendicular to the floor isn’t too difficult these days, especially using laser levels. But proper bracing requires a well thought out plan. You’ll need a design and materials that can support a roof and stay sturdy for several years.

One way to develop that plan is either to buy one from any of the many sites online that offer “build a greenhouse” plans, or study a house under construction. The same principles apply. Either you’ll need regular-spaced 2 x 4’s (usually 16 inches apart) and/or a large number of L-braces (4 inches per leg or longer).

After you have the plans and/or the actual greenhouse built, the fun starts for those who prefer to exercise their carpentry skills on furniture.

Any moderate-sized or larger greenhouse will need one or more good tabletops. Many types are available for purchase, which is fine for those who want to go that route. Do-it-yourselfers will enjoy making their own.

Here again you need to draw out what design you want before pulling out the hammer and nails or screws and drill-screwdriver. 4 x 4’s make excellent sturdy legs. Be sure to buy or cut ones that have perfectly perpendicular ends to support the top.

One excellent and simple design involves laying a flat top (say a series of 1 x 12’s with cross supports or a flat, sturdy piece of plywood) onto the legs. Nail or screw the top down onto the legs so you have something level and fairly sturdy. Then use some L-braces to increase the support in the horizontal direction.

Cap it by using plywood strips or 1 x 6’s perpendicular to the top. Connect them to both the legs and the top with L-braces. Rock solid and attractive. Stain when complete to keep moisture from corroding the table.

You can use the same method to build benches for holding rows of plants or to sit on. Or you can use a trio of 2 x 4’s attached to short 4 x 4’s or crossed 2 x 4’s, supported by a 1 x 10 running vertically down the middle and attached with L-braces.

You’ll want some simple shelves, but if your walls are glass they’ll need to be free standing.

Sometimes, purchasing a portable greenhouse is a good alternative to build a greenhouse. After all, there’s a limit to what even do-it-yourselfers want to make.

Some people, especially if they buy a pre-made greenhouse, will simply lay it on top of whatever ground exists at the location they choose. That may be gravel, or dirt or even grass. Some pre-made greenhouses come complete not only with roof and walls, but a floor, as well.

If you choose to build a greenhouse, you’ll probably want to prepare the ground underneath it in some way. This could be as simple as smoothing the earth and laying down railroad ties spaced an inch apart. An alternative step up could be creating a simple platform of eight-foot 2 x 4’s or 1 x 6’s nailed to 4 x 4’s spaced out about every 18 inches under the slats. That way you have a solid base and drainage.

But those simple designs leave you with the problem of controlling weeds, replacing floor boards, controlling mildew and other issues associated with wooden floors.

The next step up is laying a cement foundation, similar to the type under many houses. This is easier than it sounds, but it requires more effort than the other alternatives and has a few potential drawbacks.

Creating a cement foundation requires laying out an area, smoothing it and building a temporary ‘container’ around the area you intend to pour. You’ll want to make it fairly smooth and level – not an easy thing to do unless you have a fair amount of experience pouring cement.

In the end, you’ll be left with a semi-permanent foundation which would be difficult to move or remove later if you change your mind about the location.

But pouring a cement foundation when you build a greenhouse will last longer and give you some options about heating. You could lay carpet or tile on top with heating tubes or wires underneath, for example. It’s easier to take care of and very sturdy. Cement floors also can absorb and reflect a lot of heat, which can be handy in a greenhouse.

It will take a couple of weekends to build a greenhouse foundation from cement.. The materials, tools and construction plans are available at a hardware store or can be ordered online and delivered.

Beyond following the directions for mixing cement, creating the frame and properly forming the surface, the key is temperature and humidity. It’s important that you carry out the project when you expect moderate to warm temperatures, relatively low humidity and no rain.

Whichever option you choose to build a greenhouse foundation, make sure you plan ahead. Make sure the floor is sturdy enough to support the benches, tables, pots and people that will be inside. After you have all that installed, it’s much tougher to replace flooring.

The first thing that you are going to need to do is get all the necessary equipment. The most important piece of equipment you will need is solar panels. These are what will work to take the energy from the sun and convert it into energy that you can use.

If you want to know how to build a solar greenhouse, you need to know that although solar panels are one of the most important pieces of equipment you will need, they are certainly not the only thing you are going to have to get here.

You need to first choose the location, and make sure that it is one that will be receiving lots of sunlight, even in winter.

You also need to make sure that you have a good starting point for the greenhouse, which means having a solid and level foundation floor.

The benefits of a solar greenhouse are truly incredible, as not only will you be saving yourself money but you also will be doing good for the environment because you are not polluting or causing it any damage.

As long as you take the time and learn how to build a solar greenhouse before trying it on your own, you should come out of this all with some great results.

Location

The next thing that you are going to need to decide on if you want to build a greenhouse is the location. You will need to figure out exactly where you want to have the greenhouse located. Make sure that you pick a site for your greenhouse where it will get the most benefit of winter sun.

During the summer, even if it is not in direct sunlight it will still usually receive enough sunlight for the plants to strive. However, in the darker winter months there is much less available sunlight and so you need to make sure that your greenhouse is located in an area that gets the most sunlight.

Size

Also if you want to build a small greenhouse, you are going to need to determine what size of greenhouse you are going to need. A small greenhouse will be fine if you are just greenhouse gardening as a personal hobby for instance, but if you are doing it for a living you are going to need a larger sized greenhouse so that you can have more plants and more room to move around.

So rather than pushing yourself to do it and having to find spare time here and there, hiring professionals to do the job for you just may be the best idea for you.

Another disadvantage to doing it on your own is that you may get all the way to the end and realize that you did not build the greenhouse properly, or otherwise have something go wrong and have to start all the way from the beginning.
