Boy...I wasn't away but for a few hours and I've got pages to catch up on...
I can appreciate the idea of keeping it simple, with one plant choice, as it does seem to be looking like a lot of work for Suzanne; however I appreciate even more the fact that the temperature thing is being thoughtfully considered. After all, we are a worldwide forum with folks from just about every climate zone and with different knowledge levels. Using the different temperatures would be more inclusive to all.
I really want to participate and am also ready to buy, buy, buy...but then again ...there's always room for 1 more orchid, or 2, or 3...
Let me know if there's something I can do to help Suzanne...I'm a newbie to this project thing, but I'm a quick learner.
