Thanks for the hints, Candice. If I have any difficulty, be sure that I'm going to ask for help. BTW, I've been growing orchids for 25 years now. I live in the southeast region of Brazil, just under the Tropic of Capricorn. I grow around 2,000 orchids, mainly Cattleya Alliance, but also some Vandas, Oncidium, a few Dracula etc.
