I was building new Cham enclosure and I got to the foam and had it all foamed and cut was looking great and then I put on some silicone and put some coconut fiber and moss on. Came back the next day to look at it and it was shrunk from the sides of the wall like 1-2 in all around. Idk if I did something wrong I have watched a lot of people do it and never seen that so it was a shocker to me any ideas on what to do or how to fix
