1- hydro or gravel -- I use pea gravel better - big box pet store ( lots of choices however- Hydroton, False Bottom, and Drainage Later Materials | Naturalistic Vivarium Substrates | Josh's Frogs

2- fiber glass screening - ( home depot )

3- 1/2 polyester quilt bating ( fabric store) this does not remain white -after the water begins to drain through it blends right in

4 ABG soil mix ( ABG, Atlanta Botanical Gardens Mix | Reptile Substrate | Josh's Frogs )

5 Leaf litter ( Live Oak Leaves (1 Gallon) - Leaf Litter | Josh's Frogs )

The background is tree fern panel .
#2 and 3 (IMO) drain MUCH better than fabric substrate barrier...
Hi Lynn! Think will use this drainage set-up you discuss here for Imi's. Plan to use some Seachem Matrix (sintered glass) for 1st layer (have on hand) because it's lighter than lecca. Is fiber glass screening the one for windows? Where can I get the polyester quilt batting; Walmart? My local pet shop sells tree fern slabs for ExoTerra's; is that the one you use? Thank you !
