There are many choices when it comes to building the foundation of your greenhouse.
Many people, when they purchase a ready made greenshouse, will not take enough time to plan and plot out exactly the best place to put it. That may be on gravel, or dirt or even grass. Some ready made greenhouses are complete with floor, walls and a roof.
When you commence building your own greenhouse,You will need to prepare the ground underneath. Levelling the earth and laying railroad ties evenly spaced about an inch apart is all that is needed. 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.
These designs, however, leave you with the large job of controlling weeds, as well as controlling mildew, replacing floor boards and other issues with wooden floors.
Your next step is to lay your cement foundation, and this is similar to the foundations under many houses. This is easier than it sounds, but it requires more effort than the other alternatives and has a few potential drawbacks.
To create your foundation you will need to lay out an area, smooth and level it and build a temporary container around the area where you are going to pour the cement. 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.
You could be left with a foundation which would be hard to move if you change your mind about where you want to place it.
But a cement foundation 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 is very easy to care for, and very strong. Cement floors also can absorb and reflect a lot of heat, which can be handy in a greenhouse.
Building a good cement foundation will require a couple of weekends. 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.
Planning ahead is vitally important, whichever option you choose. Make sure the floor is sturdy enough to support the benches, tables, pots and the people that will be inside.The foundation is the building block, so it’s important to make sure it’s done properley.
