Thanks folks hal - thanks for the generous offer and advice. I may just take you up on the offer morphman - thanks for the advice. So far I haven't killed anything I'm afraid to put anything to close to the top so they don't burn. More pics coming soon.

You're welcome. Just to be clear my only concern is the barrier you created using expanding foam. It is not a long term structure because the foam will begin to deteriorate. would using something like clay as a natural barrier between water and foam work to prevent deterioration of the foam?

Seems there is concern about deterioration of spray foam in wet conditions. Disclaimer first: I've not tried this on spray foam, so anyone looking to try this should test it on a piece of foam first (specifically the foam they plan to use as there are a number of options out there). It might work to use a camping cheat I've been using for years. You can dilute silicone caulk and use a disposable paintbrush to create a waterproof barrier on most surfaces. Covering the foam with this material might do well to prevent water related degradation (assuming it doesn't dissolve the hardened foam of course). It's better to see it than describe it, but most of the videos online are long and poorly framed and edited. The easiest to watch video I could find on the process was this Yahoo page (honestly, that was the best). But it gets the point across. Too late for this (very cool looking!) terrarium. But might be worth it for someone else in the future. Or useful in other ways.
