well tried to silicon on the coco fiber but i guess it was too wet because when i lifted it up it all fell off. i'll retry once every thing is a little more dry
I had a similar problem when I first did this. You have the tank flipped back so the part you want to put the coco fiber on is facing up, right? You can get a cookie sheet and bake the coco fiber for a few minutes in the oven to help speed up the drying process. Bake it at 350˚ for about 10 minutes. Spread it out evenly on the cookie sheet and make sure it's not too thick. Oh yeah and make sure you really squeeze all the water out of it first. It could take a week for it to air dry if you don't decide to bake it.
Looks good, I have that same type of fern in my FBT tank. It takes a while to get used to the vivarium, but after it settles in, it grows like crazy. Is that a bromeliad on the right?
