Back in the olden days I used to go Swamp Trompin in the Florida Everglades on the weekends and shoot picture of the orchids and other plants I found in the hammocks (can't find hide nor hair of any of the pictures or negatives). I think that's where I got my preconceived notions about orchids, noticing how they grew.
Frankly I'm reluctant to put anything in full sun here unless it really likes blazing hot sun. I'll let my Vanilla get used to more light for a few weeks then move it again where it will get full sun in late afternoon for a few hours.
