I have seen conversion factors somewhere or other , and I expect I can find them on the Internet.

However, the reading alone is not quite enough e.g.I have just been outside the front door and find that the open sky reading is 900 Lux but its 9 am and raining At noon, with glorious early Spring sunshine ( I wish ) iyt may well be 50000 Lux. For your reading of 100ASA 1 sec f22 to be meaningful and transferable I want a bit more data time, weather, leaf reading ( reflected light) ? Or pointing at the glass (incident light ) -.

Todays readings are 100 ASA 2 seconds at f 22 Overcast, rain, reflected light, vertically down onto the leaves. at 1520 GMT
Yesterdays readings were 100 ASA 1 second at f 22 sunny, half cover cloud, reflected light, vertically down onto the leaves at 1330 GMT
A reading from my digital camera says ISO 100 half second at f 5.6 Overcast, rain, reflected light, vertically down on the leaves at 1350 GMT

Here is a link to a table of Exposure Values but 1 second @ f22 ( ISO 100) EV 9

http://en.wikipedia.org/wiki/Exposure_value EV_as_an_indicator_of_camera_settings

Here is a link to a conversion cart :- http://www.sekonic.com/support/support_2.asp

So your reading amounts to 1280 Lux.. That is pretty dim if it is a normal mid-day daylight level. Here on the South Coast, 2.30pm mid-February, with light continuous cloud ( light drizzle) the open sky direct light reading is almost 10K Lux, and the readings at bench level in the greenhouse are about 2-3K Lux ( i.e. about twice your light) and in the roof on the Vandas, 4-5 K Lux.

Ok so it s pretty gloomy where the Aerangis are, but what are your readings over your Aerangis, is it lighter?
I think Tricia s Aerangis grew better after mentioning stygian gloom.

Did anyone buy one, after the discussion in recent months ?

If so, what experience have you had ?

I just had an advertising e-mail from 2-Wests, and they are offering it, and
using pictures of aphids , white fly etc, suggesting an insecticidal
function . However they also illustrate roses with black spot , and I can't
see it being of any use in an open garden situation !

I think it s meant for roses grown in greenhouses. Is sulphur a cure for red spider? I am surprised at how small it is.

Subject: another question − does anyone grow Vandirea Newberry Jasmine ?
Date: Fri, 18 Feb 2011 20:25

This is a primary hybrid between V. amesiana and Sedirea japonica.

One ( of the parents) wants sphagnum moss, and always barely moist ; the
other wants a free draining bark, alternately wet and dry.

What does the hybrid want ?

Like, I can guess − but my guesses are not producing very good results.

Bournemouth Orchid Show this year is at a new venue ; no need to get lost in
Bournemouth/Pokesdown/Boscombe/Southborne, or wherever it used to be.( I did
- get lost − every year..)

Now it's a Wimborne. Nice little town − interesting Minster etc etc.

The show is in the Allandale Centre − you can't miss it − really − its on
the ring -road. And this is not like the North Circular , its only a little
market town .

If you use a sat-nav , then the post-code is BH21 1AS

THE DATE IS SATURDAY 26TH February, open from 1200-16.30. I expect you have
to pay half a crown or something to get in.the usual, anyway.

Trade displays by Ratcliffe, Plested, and Burnham.

And − special prize − you may get to see me !!!!!. Anyone will point me
out, I'm sure.

Hope to see you !

Talking of shows, just in case you missed the 'ad' in the Orchid-Talk
website front page, North Hampshire Orchid Society is holding an
Orchid and Craft Fair on Sunday at East Oakley Village Hall near
Basingstoke. Details at:

Unfortunately there is a mistake somewhere.

The Wessex Orchid Society web-site says that their show is on 5thMarch

Our front page (Orchid-Talk) says 6th March.

No doubt you'll sort it out Tricia.

OOps indeed! I've corrected it now. The correct date -5th- is shown
on the news page, which may have confused people... The thing to
remember is that Wessex shows are always on a Saturday.

Yes I'm growing it in a mixture of medium sized bark and sphagnum and keep it on the moist side.

I attach 2 pictures of the flowers.

Subject: Coelogyne celebensis vs Lyme Bay
Date: Sun, 20 Feb 2011 13:30


Hi!
Could anybody help me to separate /C. celebensis/ and C. Lyme Bay, I
can't tell them apart? I tried to look at the photos on the web and to
me they look very similar, I would even say that it looks more like
variations in a species than between a species and a hybrid.
Lyme Bay is a hybrid between /C. speciosa/ and C. usitana, so it doesn't
even include /C. celebensis./
How is it when a hybrid is registered, does it have a description that
you could use in a key to determine which one it is? I'm almost totally
in to species, so I don't know much about hybrids.

Thanks for that Peter.

I guess that I was also growing it with less light than it likes.
Corrections now made, and maybe it will like the changes. Fingers crossed.

I can't help in distinguishing , and don't have celebensis in my collection
anyway. I do have Lyme Bay which I bought on a visit to Burnham last year as
a young plant filling a 9cm pot with several leads, which I thought was
approaching FS , so maybe I shall see a flower when the new growths start
shortly.

But as to your second point, it is "necessary" to provide a description of
the flower of a new hybrid, or a digital image, when registering it − but
this is only so that someone at Kew ( presumably) can give the nod and say,
OK, go ahead with that one. This follows some fuss when a certain US
trader, who shall remain nameless, registered a lot of hybrids which
exsisted only in his mind. These descriptions remain unpublished and as far
as I know , are inaccessible.
