Now many families will use foam boxes to grow vegetables on the balcony to "be self-sufficient". Foam boxes are easy to collect in the vegetable market, and can be used as flower pots to grow vegetables simply by digging a few holes, which is very convenient.

But at the same time, we also heard that "foam box decomposes and causes cancer when heated", "a family eats three mouthfuls of vegetables grown in foam box and the whole family suffers from cancer", "Friends who grow vegetables in foam boxes must stop at once! According to the hospital doctor, three members of a family were hospitalized with cancer in their department. After inspection, it was found that he grew vegetables in foam boxes at home and ate his own vegetables for three years to eat the cancer! He thought that he grew vegetables in foam boxes healthily with less pesticides, but he did not expect that the foam boxes were more powerful than pesticides. Tell me about the rumor that growing vegetables in foam boxes would cause cancer, then what is the truth of the matter?

Can foam boxes grow vegetables? What material is foam box?

The component of foam box is polystyrene, which is made by suspension polymerization of styrene monomer and adding foaming agent. It is also a kind of plastic, and these chemicals cannot be decomposed by microorganisms.

Can foam box decompose carcinogens at high temperature?

Some people may question whether this material does not produce carcinogens at room temperature. If you plant vegetables on the balcony, exposed to high temperatures in the wind, rain, and wind, will it easily decompose into carcinogens?Manufacturer of foam boxTell you:

In fact, Professor Zhang Junying from the School of Materials Science and Engineering at Beijing University of Chemical Technology conducted an experiment on this issue many years ago: Professor Zhang conducted an experiment to verify it through two methods. First, weigh a piece of plastic foam in advance, then boil it in boiling water for three hours, and then weigh it. If it decomposes, its weight will decrease. While using the weighing method for the experiment, chromatographic analysis was also used. If a substance enters water, its chromatography will undergo certain changes.

Both experiments have shown that polystyrene is also very stable at high temperatures.

The foam box is also a kind of white pollution. The so-called white pollution means that it is difficult to decompose after being buried in the soil for decades or centuries. If the foam box is so easy to decompose carcinogens, there is no such thing as white pollution. In addition, the lunch box we usually use is also made of polystyrene, which is the same as the foam box. If this material is easy to decompose toxins, the country has already promulgated laws to prohibit it.

In terms of the growth characteristics of plants, apart from the water in the soil, plants can only absorb some ionic components of minerals. Even if large molecule carcinogens such as benzene are truly decomposed, the plant roots cannot absorb them.

Therefore, unless poisonous substances have been stored in the foam box, there is no need to worry about carcinogenesis when eating vegetables grown in the foam box. Eating food grown in foam boxes will cause cancer, which is totally a rumor. Don't believe it.

How to use foam box to grow vegetables and flowers

The rumor that growing vegetables in foam boxes can cause cancer is not credible. How can we use foam boxes everywhere to grow flowers?

Choose a suitable size

First of all, we should select the appropriate size of foam box according to the size of the balcony. Once the foam box is filled with soil, it is very heavy, so we should first select the size, and then we don't need to move it again.

Punch the foam box

Make some holes at the bottom and side of the foam box. If it is hydroponic vegetables or flowers, it is not necessary to make holes. If you prefer vegetables or flowers in moist soil, you can drill fewer holes. If you prefer vegetables or flowers in dry soil, you can drill more holes.

Pour into the soil

Pour the fertile soil into the box with holes made, and fill it approximately 8-9 minutes. If planting vegetables, attention should be paid to selecting fertile soil without pollution, such as rotting leaf soil and pine needle soil. Contaminated soil, such as soil near garbage dumps, should not be used.

The processed foam box can grow your favorite vegetables and flowers. Using foam boxes to grow vegetables and flowers will not cause cancer, but also protect the environment. Let's do our part to reduce white pollution.
