Is it toxic to grow vegetables in foam boxes? The latest answer is here

One, is it toxic?

Foam boxes are a container many people like to use for growing vegetables, because the material is lightweight, and moving them, punching holes and so on are all very convenient, but many people have doubts, worrying that using them to grow vegetables will be toxic and harm health. Actually, foam itself as a material has no toxins; as long as it is not eaten directly and not heated, it will not release anything outward, so there is no problem with us growing vegetables in it.

But as the time a foam box spends outdoors and the growing time lengthen, some external factors will change the outer material of the foam box, such as sun exposure, wind and water, air pollution and so on, so it may release some harmful substances inside. In addition, the soil we put into the foam box when planting, as well as certain fertilizers, contain some substances and chemical components that may react with the plastic, foam and other materials of the foam box, releasing harmful substances, so it is not recommended to use it for a long time.

Two, how to avoid it

When using foam boxes to grow vegetables, do not choose boxes made from inferior pollutants, and it is also not recommended to reuse them in cycles for a long time, especially boxes exposed to the sun outside on a balcony, which should be replaced in time. If conditions allow, it is recommended to buy special vegetable growing boxes, which are a bit better in drainage and water retention, and relatively safer.
