Gardeners love mini-greenhouses because they allow them to cultivate a wide variety of plants, including herbs, vegetables, and berries. For example, they might grow strawberries, cabbage, cauliflowers, radishes, beets, onions, potatoes, and more in the small greenhouse they have.

In the food industry, we may look at how much money we save on our weekly grocery purchase. As a result, fruits and vegetables make up a significant portion of my grocery budget. In order to survive on the harvest, we’ll need to do more than just plant a seed; we’ll also need to provide year-round support for the plant’s growth.

Growing veggies for testing is simple, but cultivating a supply of food requires more expertise. But there’s nothing to be concerned about. It all boils down to timing, weather, and using a greenhouse to change those variables.

Building a greenhouse isn’t difficult when you utilize the correct kits. Here are some of the elements your self-sufficient, food-bearing, survival greenhouse has to have for food insurance.

How does a greenhouse work?

For backyard farms, greenhouses are your best friend since they can recreate the ideal temperature for veggies to thrive. Fruits, vegetables, and herbs can all fit within this category. When it comes to summer crops, most gardeners start with a few seeds in toilet roll holders, styrofoam cups, egg cartons… basically anything you can find. A temporary pot is a pot like this. Their sole purpose is to allow seeds to germinate and flourish indoors while the weather is still chilly. It gives them an advantage over the summer crops if you put them outside.

As long as you can manage the temperature, you can grow crops all year round in a greenhouse. So long as you can control the temperature, a greenhouse lets you keep growing all year long. Pollination, on the other hand, is something that may either be done manually or with the help of bees in the greenhouse.

In the greenhouse, you can grow year-round crops such as tomatoes, peas, peppers, and eggplants (to mention a few) while still maintaining a healthy balance between summer crops and those recalcitrant winter crops throughout the colder months. This is possible because of the greenhouse crop rotation.

To keep their crops going during the winter, some farmers are employing a variety of strategies. One small greenhouse owner I know uses an electric heater on a timer to manage the temperature within the greenhouse. As soon as the sun rises each morning, they come in to water and protect the plants from freezing temperatures. For 20-minute intervals, the timer is activated during the colder periods of the day and night to maintain the temperature stable.

What size greenhouse should you have?

When it comes to generating enormous, nutrient-rich, food-bearing plants that can sustain your family for years to come, a survival greenhouse needs to be large enough to allow for expansion and diversification.

It’s possible to cultivate a greenhouse large enough to feed your family for decades after the end of the world if you’re familiar with the various systems involved.

Because of this, it’s a good idea to build your own greenhouse or acquire a greenhouse construction that can be expanded. There should be at least 20 feet of length and 10 feet of width in a greenhouse for prepping. One individual (or a small family) can cultivate a high-yielding garden in this amount of space.

Science, on the other hand, suggests that this isn’t always the case. plants have a circadian cycle like people, which necessitates a slumber phase for optimal growth. While your survival greenhouse should be able to provide your plants with the light they need, it should also be able to shade them at the proper times.

As a result, your plants will be able to grow steadily and produce the maximum food for their size and space.

Controlling temperature in a greenhouse

While we don’t know what temperatures the end of the world will bring, summers and winters are currently scorching and cold. A greenhouse is the only option to maintain the ideal temperature year-round for plants, which typically prefer temperatures somewhere in the middle. During the summer, the sun’s heat helps to regulate the temperature in the air.

The Mr. Heater and the Patton Heater, two popular portable heaters, are simple temperature control systems. HVAC units, on the other hand, have a plethora of ductwork. Installing heating and cooling systems that maintain a constant temperature is essential if you plan to only rely on your greenhouse as a food source. The greenhouse’s energy consumption won’t be significantly impacted, but the health of your garden will be considerably improved even in adverse weather months.

Electronic thermometers, such as the Thermopro, are also an option for greenhouse temperature control because they are economical and of their high quality. Cooling rooms and removing stagnant air from around plants are two common reasons for increasing the airflow around them. You can fix this by purchasing an AC Infinity or a Hurricane wall-mount.

A sprinkler system should at the absolute least be on a timer to control the amount of water that seeps into the ground. As a final precaution, you should have some kind of ventilation in your greenhouse to avoid mildew or mold from suffocating your plants.

Maintaining security for your survival greenhouse

Prior to completing the construction of your dream greenhouse, you must consider security measures. In the event of a natural disaster, having a reliable supply of food stored away will be quite useful, as other survivors will be ready to take advantage of your generosity. For example, in Venezuela’s food crisis, those who band together to grow their own food must maintain frequent security patrols because there are people who would benefit from stealing their food. It’s a good idea to maintain your survival greenhouse not only secure, but also discrete, hidden, and blending in with the rest of the landscape in the event of a disaster.

According to Rick Austin’s book “Secret Greenhouse of Survival,” you may construct a greenhouse that doesn’t appear like one at all, and you can conceal your greenhouse with landscaping elements like trees, fences, and other structures.

In spite of these safeguards, you should nevertheless install robust locks, motion-activated lights, and other security systems that alert you to the presence of burglars and slow the theft of crops. To deter would-be attackers, consider more inconspicuous security measures that blend into the landscape and don’t draw attention to the fact that you have something of value on your property.
