Is Thermocol good for plants?
Regarding this, can we grow plants in Thermocol?
You can grow garden vegetables in most containers, but thermocol boxes are ideal. They are light, easy to manage, and the foam helps insulate the roots. Use deep boxes to give your veggies plenty of space to grow their roots.
Regarding this, is Styrofoam bad for plants?
The answer: Not really. In fact, if you are using a pot with little to no drainage, adding Styrofoam packing peanuts could do more harm than good. Deep plant roots can grow into the foam material, and without sufficient drainage, they can become waterlogged and rot or die.
Because foam is a man-made material, concerns have arisen about chemicals leaching from foam into the soil and contaminating plants. The report also says, however, that foam is safe to use around food; the danger lies with workers in industrial facilities that build items such as boats with styrene.
