Sorry for the delay, June was really busy so I didn't have time to go over the list of plant suggestions. I'll have plenty of time this weekend though!

I believe I missed something. I'm new to the whole project thing and was reading over this thread but...
What exactly is this project? Everyone grows the same plant and we compare results?

I believe what was decided (based upon the poll) was that we would all choose the same plant/plant type to grow and compare notes/results/etc as we progress.

I think now we are at the stage of suggesting plants and narrowing down.

Ok I think I got it now. I like the idea of a phalaenopsis, because I was already looking at mini phals.
Alternatively has anyone suggested a jewel orchid? Something like macodes petola?

Again! :) Laelia harpophylla or vasconselosiana.

They're already in the list, but I think I was concerned about the size of one of them, which may be rather large.

None of them is a large plant so it won't be an issue, I think.

From what I read, Laelia harpophylla growths are about 30cm tall, and mature plants in bloom are something like 75cm. I would call that a large plant.

Either way, how available are those laelias?

Not very available, as far as I could tell. This weekend I was checking the size and temperature requirements of all the orchids in the list, and for the Laelias I hardly found any information, and very few vendor websites were in the search results.
