how to say 'foam box' in french? hi, I was trying to say 'foam box' in french, box made of foam, sort of like the ones used to store ice cream, only much bigger that you can use it to grow vegetables, I googled it and got 'boîte de mousse', then I searched for pictures of 'boîte de mousse' and all of them is just a plastic box with a thin foamy layer, and that's not what I wanted. can someone please point me to the right translation? thanks a lot!
