Plants are likely dead. Terrs, generally speaking, should never be left in the sun -- especially if it happened to be a "sealed" terr. Temps get far too high too fast. (Consider how quickly and how hot a car sitting in the sun gets.) High probability that the plants got cooked ... roots included.

Hello Paul, thank you for your reply. I have managed to create my own tools and replanted the plants. They are now doing very well and growing day by day!
