(Homesteading.news) Being able to grow food year-round is important to homesteaders, but if you live in a part of the country where winter brings colder temps and snow, you also know that it’s impossible to grow food without a greenhouse.
But many homesteaders value the sanctity and wholesomeness of the Earth. If you’re one of them, then this greenhouse project is for you because it will allow you to plant directly into the ground, even if you live in the extreme northern part of the country.
The one thing you’ll need, however, is a good sturdy foundation, in order to keep your greenhouse on steady footing year-round and as the winter cycle freezes, then thaws, the ground outside your structure.
While most greenhouse kits you can buy commercially recommend either pouring a concrete foundation or using railroad ties, you can also construct a heavy frame out of other wood. As noted by Common Sense Home, these homesteaders settled on the following design:
There are six 8″ concrete tube footings (one at each corner and one midway down each of the 20 foot sides). These are tied together with 20 foot long 2″x10″ boards (stringers) bolted through each of the concrete tubes and 10 foot long 2″x10″ boards (stringers) bolted into the 20 foot long boards. This box frame is back filled with dirt to eliminate any space where varmints might want to move in and maintain a more uniform temperature and moisture distribution around the wood. Finally, the box frame is capped off with 2″x12″ boards and the greenhouse is secured the the 12′ wide boards.
The designers note further that when choosing wood for the frame, chose wood that is recommended for below-grade installation – your local lumberyard will know what that means. Understand that the wooden frame will be sitting damp for a long time and if it’s the wrong type or used in the wrong way, it won’t last. The key is getting your greenhouse to perfectly square with your frame, to keep out cold air.
But you can choose another design. In fact, the “Quonset hut” design is also very popular.
Now, there are other things to consider before building your greenhouse:
Don’t forget that many hands make light work. You have some friends, no doubt, who would not only love to help out but likely want one of their own once they see yours (and you can return the favor when they build theirs).
