- They have airflow and some drops of water from the sky when it rains.
- They get light but no direct sunlight, there's a roof about 1m long right above them, so all the light they get is reflected from the wall that's just in front of the house or from the floor.
- Highest temperature is around 33ºC and lowest should be 6-7ºC.
I'm no one to argue with what works, so it sounds and looks like they're doing just fine! She would only have to worry about bugs, there are tons of them that love to feast on orchids.
Orchids aren't really all that bad once you know what they want. Phals are said to be the easiest and that's probably true, although they're not "easy" if you're growing indoors. Dens tend to like cooler temps so it loves those cool nights but it probably suffers a bit in the heat.
Nalani, that's something I've really wanted to do for a long time, visit an orchid grower in Hawaii. I've actually bought a few from a company called Exotic Orchids of Maui and some plumeria from a Hawaiian grower also. You guys have the best environment for them, that's for sure.
Tommy, that's one of the things that draws people to buy the Phals, that they bloom for so long. You see them everywhere in commercials, movies, etc. The only problem comes in when they stop blooming and you're left with a few non-descript leaves and roots poking out all over. Most people chuck them or give them away at that point, figuring there's something wrong with them. But they all need a rest period and it's not that easy to get them to rebloom when they're used to the pristine conditions of a greenhouse.
I only have one Phal left. All of my other orchids are more exotic types which demand much more care. One of my favorites named for a Hawaiian man, I read the store on why it was named this but I can't find it now.
