Vandaceous that tolerate low humidity (I'm talking about 30%)

[blackorchid]

Hi, do you think Aerangis, Angraecum, and Sedirea would tolerate low humidity for home-growing. I'm interested in any fragrant miniature. Any specific species (or hybrid?) suggestion is great! I got a Neofinetia and it's doing great. I'm in love with that one even without flower. I want something with similar vigor that can live in a dry area.
Thank you!

Almost all angraecoids (aerangis, angraecums, etc) cannot tolerate such low humidity (under 60%)

Perhaps Neofinetia hybrids like Neostylis and others might do OK in low humidity but with constant misting?

GOOD LUCK WITH THAT ONE!

Vandaceous species dont have to big a problem when it comes to humidity. I have grown several hybrids and species indoors with very low levels of humidity, Im talking ten percent or less, you can have success as long as you adjust your growing situation. Instead of growing them in baskets try using clay pots of medium bark for vandas, Rhynchostylis, and hybrids containing them except when also containing Neofinetia or ascocentrum. Use the same clay pots with fine bark for ascocentrums and hybrids containing them or renantha except when also containing neofinetia. Use clay pots with Spag moss when growing Neofinetias or hybrids containing it as they like a more evenly moist enviorment. Avoid hybrids containing Tricoglottis, Jumellea, Angraecum, or Mystacidium as they do require humidity also avoid extreme minatures from the angraecum or Jumellea unless you have a terrarium in which you can provide humidity around seventy plus percent. Hybrids containing other genre are still a mystery to me but if you are willing you may expreiment with growing them. Remember you willl have to keep most of these plants warm and close to either a window or light fixture.

Also check out the glass vase method, soaking daily, and plenty of light.

Hmmm, I'll be more specific:
-Angraecum leonis
-Angraecum didierii
-Aerangis fastuosa
-Aerangis citrata
-Sedirea japonica
Which ones will do good in my environment?
A side note though....Someone told me that the Aerangis and Angraecum are not vandaceous, they belong to Angraecoids?? Someone please correct me.

Quote from "Vandas and Ascocendas"...David Grove....
"the genus Angraecum is in the Angraecinae subtribe of the Vandae tribe...
Sometimes the book seems like chinese to me. Learning a lot, when I start getting a headache I look at the pics.

Forget the Angraecoids (Angraecum and Aerangis). In general they require a very high humidity to blossom well. Yes you might get them to grow and, perhaps, grow well. But blooming will be notta. I grow Sederia just fine in humidity as low as 30%. I have one mounted that gets daily ferilizer/water dunk and one in pot that gets top misting daily and watering a couple times a week. The potted one seems to be more robust, suggesting the plant likes this more?

Others to consider if you can provide the light are:

Mounted Brassavola, especially B. "Mickey Mouse"
Dendrobium senile
Sophronitis cernua
Dendrobium anosmum
any of the Tolumnias

Most of these require pretty high light to blossom but you can supplement window light with CF fixtures like this

Even in south window, like this, dismal Northern Latitude winter days can be overcast and really low light. I treat my setup as primarily compact florescent lighting supplemented with infrequent sunshine. Your success should be similar.

Angaecoids are in the tribe Vandeae. There are three subtribes: Aeridinae, Angraecinae, and Aerangidinae. There are all-told about 150 genera and over 2000 species. Most are found in Western Africa or Madagascar. Aeridinae are found in Asia and Australia.

Hope this explains things a bit. It's a group of genera large enough to produce a coffee-table sized book of over 400 pages which only purports to cover two of the 3 groups and imperfectly, at that.

Growth conditions of the whole group are similar: high humidity, breezes, frequent watering (sometimes with winter dry-down), Vandaceous growth, medium to high light, epiphytic or lithophytic condictions, etc.

I agree with Ross, only the Sedirea japonica will probably do OK in low humidity, provided it gets enough moisture at the root AND enough light.
