A new greenhouse project: drop waterfall

[Faerygirl]

I am getting ready to start a new greenhouse project this spring. I am going to attempt to build a drop waterfall that goes 5-8 ft (still fuzzy about all the details) that drains and recirculates from a pondless chamber.

Part of my project includes removing a large plumeria tree back to a container (it is the tree I have posted that cuttings are available for trade in the classifieds section).

I thought it might be fun to post photos of the project as I start it and it progresses, so that anyone who has any ideas for me can school me along the way. I have built two other water features in the greenhouse (a pond, and a 20 ft stream) in the past, but this is a little more challenging. You might be able to point out things to me that I might be able to do better or easier.

I hope you will! I'll be taking the "before" photos later today if I get a chance and posting them here. I love other people's suggestions, plant people are generally very creative folks.
