How To Build A $300 Underground Greenhouse

By February, canned food is starting to taste boring; you’re craving a fresh, ripe tomato for your sandwich or a handful of strawberries picked from the vine. Unfortunately, you have a few more months to wait for your garden to produce. But what if you didn’t have to? What if you could just walk to your greenhouse any time of year and pick yourself some of what you’re craving?

This sounds crazy, or at the very least expensive, but we’ve found a great way for you to do just that. It’s an underground greenhouse that you can operate year round.

You probably already know that the ground only freezes so deep. That’s because the inner temperature of the Earth isn’t affected by seasonal temperatures. This depth is called the frost line and it varies according to where you live. Still, it’s rarely more than just a couple of feet deep. The obvious solution for growing vegetables year round, then, is to build a greenhouse below the frost line!

This answers two problems: you can have fresh produce year round if SHTF, your garden won’t be obvious so your risk of getting robbed will be significantly reduced.

Greenhouses can be expensive and we know that cost is often an issue. Fortunately, we can take advantage of the knowledge of those creative minds who’ve already forged ahead of us. In this article, you can learn about how to build an underground greenhouse for about $300!
