Just starting my new terrarium (for a Crested Gecko) in a 45x45x60cm Exo Terra. I haven't began construction but have been gathering all the stuff I need to begin. So far I have...

Large cork curl
Large sand-blasted Grape vine
Egg crate for false bottom
Filter Mesh
Coco fibre
Sphagnum Moss
Water pump
Heat mat

All I need now ..i think.. is silicone and foam. The thing is here (UK) I cant seem to find 'GE 100%' silicone or 'Great Stuff' expanding foam anywhere. What can I use instead?

I have black and brown silicone for windows and doors. It doesnt have any mould repelant in it... With this do? I have 3 weeks to let it air out. As for the foam, since I'll be sealing it totally with silicone, surely any foam will do?

Thanks for your time
