COVID-19 came to all of us unexpectedly, and a lot of people, even brilliant people, were not prepared. Most people used to get food from the local supermarkets and did not expect any food shortages and food contamination, but it happens, and a lot of people ask as what should we do?
Our blog will gradually bring to the idea what size of greenhouse to buy depending on your family or commercial needs.
Going back to basics
The best advice is to go back to the basics. Start growing your food. It is not complicated. Not only that, but it is also much chipper and fresher than to whatever you can get food from any supermarket.
Firstly, it is to go on-line and buy a reliable greenhouse. There you can grow fresh produce (strawberry, blubbery, blackberry, gooseberry, raspberry, string beans, cherry tomatoes, plum tomatoes, beef tomatoes, cabbage, lettuces, zucchini, cucumbers, parsley cilantro, green onions, carrots, onions, leek, watermelon, honeydew, cantaloupes, bell pepper, Italian pepper, eggplant, broccoli, cauliflower, etc.)
Before you shop for a greenhouse, you should understand what kind of greenhouse you should look for and what to expect from this greenhouse to work most effectively for you and your family.
Why to even consider a greenhouse
You can grow food under the open air; however, in today’s climate and weather fluctuations, you will be very discouraged in 95% of instances.
What the greenhouse will give you is the surety of getting your produce, and not only; we will talk about it a bit later.
Your greenhouse must be ready to withstand wind of at list 20 miles an hour, and therefore it must be anchored to the ground. It does not have to be bolted or cemented to the ground. There are bolt anchors that you can install within 5 min by yourself. Depending on the size of the greenhouse, you will need a least four of those anchors.
The second item you will need to look for is at the greenhouse is what is it covered with.
Types of covers
There are greenhouses covered with glass, polycarbonate, polypropylene, and polyethylene foil.
Glass greenhouses are too expensive and are not needed, especially for the hobby growing.
Polycarbonate is also very expensive and not efficient since polycarbonate passes not a lot of sunlight.
There are greenhouses made out of polypropylene, most of them are in green color. Read about the effect of polypropylene on human organisms in the articles published by Cornell and Pen state universities.
In-plane language, polypropylene used in growing produce and used in any food processing, is very dangerous to your health, with the possible cancer consequences.
THE BEST AND MOST EFFICIENT COVER FOR ANY GREENHOUSE IS POLYETHYLENE FOIL
Remember, to grow the produce in general; one needs four conditions: Sun radiation, higher than ABOVE 0C or 33 F outside temperature, water, and air.
So now we established that we are looking for structure covered with polyethylene foil, anchored to the ground with the steel anchors, mostly pipes. The structure can be made out of wood or tubes (hollow steel); however, the best one is made out of tubes.
It is the pre-galvanized tubing of about 1″, 25mm in diameter. If you buy it on the Internet, look for the specification of the tubes’ diameter, which is crucial.
What your greenhouse also has to have is plastic or metal clips to attach the foil to a frame and a special zip spring to hold the foil and the mash for letting the air in.
Your greenhouse should have at least one door if it is small, preferably two if it is medium or more substantial. It also preferably has to have openings on the sides; those greenhouses are cold multi-seasonal greenhouses. You can grow in there to produce in them several times during the season.
Greenhouse doesn’t need to be pretty; however, it does need to be effective.
What size of a greenhouse should you buy
Beautiful greenhouses at the end of the day are suitable for keeping the flowers in and storing the bikes.
Now let us talk, how big a greenhouse does your family need.
According to the British academy of science, the human body needs to consume about seven portions of vegetables and fruits per day. These seven portions represent about 3.5 Lbs or 1.4kg.
On average, after you will learn how to do this right, your greenhouse will get you about 3.7 Lbs of produce from sq foot per year.
So for one member of your family, you will need 346 sq foot of greenhouse space.
The cost of growing any of the product should not cost you any more then $0.1 per Lbs if you did this by yourself every day, spending only about one hour a day.
You have a family of 4, so you will need to grow 5108Lbs of produce within the season divide this number by 3.7, so you will need about 1380 sq foot of greenhouse floor or about 155 sq meters of greenhouses.
You can have one structure or four of them; it is up to you to select.
We believe the quality structure should not cost you any more than $5.5 per sq. foot. This building will be amortized with at the very least 15 years; all you need to change is just the foil, which is readily available and inexpensive.
So the greenhouse will cost you about .36 cents per year per foot, but if you add seeds and change of foil, you should not pass the estimated price of 0.1 cents per Lbs of produce per year.
Now you most definitely know, were this produce came from, you grow it your self. You can eat it fresh, or can and consecrate it, or dry it or freeze it. You will still satisfy the requirements of the British Academy of Science.
Positive side effects to expect
Now you are fully protected from Covid-19 or any other viruses. You will be healthy, mentally, and physically fit.
