Thanks for all your info!
I could grow them outside in the spring, and /or bring them closer the light. But then again I have a temperature problem. Well, I have to figure out how to behave.
I also grow Masdevallias, they have to stay inside all year around.

the total mount of light isn't important, that's the intensity (amount/surface unit; lux)which is primordial. 11000 lux is quite low for Oxyglossums, but could at least maintain them alive. Of primordial importance is also air movement. they really need strong air movement to grow well. |

The temperature is 13 degrees C. at night and 21 degrees C. during the day. Humidity is 90 % RH at night and 70% RH during the day. So that I think is ok. I plan to make a very short mist spray ay dusk and one very short at dawn just to moisten the leaves and kompost surface (live Sphagnum)

Hello Laurent!
Ok, I assume the total of 12 hour of my HQI will not even come close to sunlight 5 hours per day. I measured the sun a couple of days ago, it was low winter sun and it was 82000 Lux. My HQI give 11000 Lux over the plants 3 x 70W. do you think the total amount of light is counted or the intensity? What do you believe?

hello Hans
no problem with 12 hours of light! using artificial light, your intensity will most probably be much lower than tropical sun, anyway. In my experience, Oxyglossum really love strong light, as long as it doesn't cause an important increase in temperature (and take care of air humidity as well!)

Around noon, just what I expected. I try to mimic the highland condition as close as I can in my basement greenhouse. If I give the plants 12 hours intense light it might be too much?
Thanks Laurent! |

indeed the stunted trees/tree ferns of PNG hihland probably don't offer much sun protection, but as the Baker's book states, the temperatures usually get to their maximum around noon, when skyes are still clear, then cloud, mist and rain develop and prevent any further warming. I've not been to PNG, but have observed this in Ecuador cloud forest/paramo, which has similar climatic conditions.

Strange, never a cloud, never fog or rain, always full sun? I don't believe it. Anyone who really knows?

The highland don't have high tree , the oxyglossums are always under full sunlight .

I am curious about how many hours of direct sunlight the highland oxyglossums in PNG receive each day on an average per year? I assume that the clouds, fog and rain darken the sky substantially, so in real life there is maybe 5 hours per day intense sunlight? anyone who knows? Wolfgang H. Bandish maybe - who has been there, maybe?

I have a photo request, particularly from those of you in the Australia/Oceania regions. In the preparation of some upcoming lectures, I would like to find and borrow some decent shots of three beetles that are orchid pests. Photos of their damage to orchids are sought, also. Available images on the Internet are generally unsatisfactory. Full credit will be given for any images. The critters of interest are: Stethopachys formosa (Dendrobium beetle), Xylosandrus compactus (black twig borer), and Orchidophilus peregrinator (lesser orchid weevil).
Thanks

Hello everybody,
Well i 've read that it is usefull to use a fungiside once a month (or more) so as to prenevt infections, such as physan20, but there no such things to Greece...  Could anyone suggest something else instead? For example, is blue stone (disolved in water) good enough? And by which occasions should (the fungi- or bacterialside) be used? Can it be used to prevent infection or only after infection?
Any help is aprreciated... 
Thank you in advance...
Regards,Thanasis |

My clowesia is mounted on a fence Paling, in Winter just a spray once a fortnight should suffice then in summer as much as you want the same with fertilizer. When the new growths appear wait until they are approx 10cm long before watering and then a dose of blood and bone |

Re the PNG Bulbophyllum aff. elephantinum, } as per the image in the Orchidspng website. Can anybody assist by supplying cultural, or climate information such as where and how it grows etc. I can find no reference apart from the photo in the above mentioned website. Thanks John McAuley, Sydney Australia. |

Shermanso…
Although epsom salt has some beneficial properties, to Orchids it will not help induce flowering.

I was searching through the internet, and came across an article saying that epsom salt will help to induce flower bud in phalaenopsis. Any comment? |

Yes, Sherman So
This is quite a common occurrence…this is advantageous growth. It is producing a copy of it’s self. Commonly called ‘kieki’.
Waite until the kieki has two or three roots about two inches long, cut it from the spike and pot it up.

One of the phalaenopsis developed what appeared a (flower) spike It is about an inch long now. The tip of the spike now start to develope leaf. Have any one see this before? |

Roy posted this almost 12 months ago when the OGD was going through one of its many exchanges between parties of differing views (to put it mildly)
