Why can't you grow vegetables in a foam box?

Growing vegetables in a foam box may be harmful.

If foam or plastic is toxic, it may be an additive in the foam box or plastic box, or toxic substances such as heavy metals are installed at the factory, which will cause harm to the body. Generally speaking, foam boxes release little toxic substances, plants have purification ability, and it is safe to grow vegetables. The common foam box or plastic box belongs to organic matter, which is relatively stable and has a solid and huge polymer molecular structure. Even after natural high temperature exposure, the decomposition is extremely limited, and it is difficult for plant roots to absorb foam box substances.

Compared with traditional planting, using foam boxes is cleaner and healthier. Although the foam box looks light, it is actually stronger. Compared with traditional ceramic flowerpots, foam boxes are really clean and hygienic. Using foam boxes to grow vegetables can save space, and even adopt shelf-type and multi-layer layout. Using foam boxes to grow vegetables can not only satisfy the desire of building residents to grow vegetables, but also cultivate their sentiments, and they can also eat their own green food, which is really a sense of accomplishment.

Matters needing attention in cultivating vegetables in foam box

Vegetables planted in the foam box will leave a lot of vegetable roots in the soil layer, which will naturally rot after a long time. When it is not completely rotten, it is easy to entangle the roots of the next crop and affect the growth. If the vegetables planted have certain waterlogging resistance, or the box is deep, water holes can be made in the middle and lower part of the foam box, so that a certain amount of water can be stored at the bottom of the box, so that vegetables are not prone to drought and waterlogging.

The soil at the bottom of the foam box will be relatively wet, the air permeability is slightly poor, and the space of the foam box itself is also small. When planting the next crop of vegetables, firstly, pour out the soil, break it up, pick up the obvious roots of the previous crop of vegetables, then dilute it, expose it to the sun 1 day, and turn it over twice during the period; Then, before sowing or transplanting vegetables, mix a proper amount of plant ash and chicken manure with the decomposed dry manure, and put it in water for wetting.
