Regarding Physan being banned, you might find this interesting. I emailed the manufacturers of Physan and asked about the supposed ban. Their answer is below.

Subject: Akerne's RAIN MIX
Date: Wed, 02 Sep 2009 23:30

Hello all,

A lot of discussion has been going on on rec.gardens.orchids lately
concerning our 'RAIN MIX' and the amount to use per litre.

I thought the group here would benefit as well from our answer we typed as a
response to some questions received directly.

The recommended dosage for RAIN MIX is as follows:

0,5 g/l ~ 520 µS/cm ~ pH 6,1

A little note concerning TDS measurements:

A TDS meter measures the conductivity of a saltsolution and gives, through a
conversionfactor, a reading of the amount of disolved salts expressed in
ppm.

Most TDS meters have a conversionfactor of 0,50 and are therefore correct
for measuring NaCl-saltsolution.

0,01 mole/l solution of NaCl contains 585 mg NaCl/l and gives an EC value of
1155 µS/cm.

585 mg NaCl/l 585 ppm TDS

585 / 1155 0,506

Unfortunately we are not measuring a saltsolution of NaCl, but a NPK
fertilizer saltsolution. Every salt in that mixture has a different
conductivity.

In a mix of salts one must take into account the contribution of
conductivity of each individual ion and also the interactions between these
ions. Therefore one must use a different conversionfactor for each different
combination.

On regular TDS meters the conversionfactor cannot be adjusted/changed, on
more expensive, professional meters this can however be done.

Test:

Put 1000 mg of RAIN MIX in beaker of 1000 ml. Add demineralised water and
shake until all salts are disolved.

Measure the amount of salt with your TDS meter. You would expect to obtain
1000 ppm TDS, however this is not the case!

For this reason in professional horticulture µS of mS is used and not TDS.

Likewise the amount of N is expressed in mmole/l and not ppm.

How much ppm N does a solution contain with 0,5 gr RAIN MIX / liter?

- NPK RAIN MIX 13-3-15

- amount of N 13%

- 130 g N per kilo RAIN MIX

- per 0,5 g RAIN MIX you have 130 g / 1000 g * 0,5 g 0,065 g or 65 mg N
present

- this 65 mg N is in 1 l of water 1000 ml 1000 gr or 1000000 mg water

- 65 mg/ 1000000 mg 65 ppm N

In order to give you extra information have a look at the following (source:

http://los.lon.imag.net/MiscFiles/fert1.htm )

With our recommended dosage (0,5 g/l to obtain a conductivity of 520 µS/cm)
we are closer to the 50 ppm N in the below charts to make it easier for you
all.

Our recommended dosage caters for all orchids be they salt sensitive plants
like Disa, Pleurothallids in general over to Paphiopedilums to the really
big eaters like Cattleya and Cymbidium and requires NO flushing with pure
water.
Hence our dosage is a good value for all type of orchids and has been tested
for over 2 years on our orchids (no exclusion) and the mixed orchid
collections of a few selected orchid amateurs!

If you look at the 125 ppm N column, recommended by a US grower, than you
will see that the conductivity is 1000 µS/cm this means you will run into
problems with salt sensitive orchids and you MAY need to flush with pure
water every x time!

A complete waste of fertilizer and money ;-)

If you cannot see the below charts properly then please visit the page
mentioned above and go the section on the 13-3-15 fertilizer!

Hi to all of our U.K. Members,

I hope to pay a visit to the Bath Flower Show [Shepton Mallett] this coming weekend, and I see that one of the Exhibitors is:

Marina Orchids. Do any of you have any information on them?

Cheers, Rodge.

Hi all,

Since my asking for information on Marina Orchids................................thought I recognised the phone code...............they are just down the road from me...........in Lymington.

Seeing that they are also a Fuchsia Nursery, and as they advertise:

Garden maintenance is carried out in the following manner:
a.. lawn mowing
b.. weeding
c.. digging
d.. planting
e.. pond laying
f.. patio laying
g.. steps laying
h.. fencing
i.. hedge trimming
and anything else we can handle.

Good on them for trying to keep the pennies rolling in, but I will not hold my breath on the orchid front.

Cheers, Rocky.

Subject: another orchid display not to worry about missing,,,
Date: Fri, 04 Sep 2009 14:20

Whilst staying with friends 75 miles away from home they took me to see a
garden with a special treat ( for me, they said), an orchid house !......
(wow ! )

This is at Houghton House Gardens, which are near Stockbridge. They also
have "The Hampshire Hydroponicum". ( it is actually much nearer to where I
live , maybe 30 miles or so − the friends had not realised...)

The orchids only made me cry. No shade − just bare clean glass − in a
south-facing section of an old greenhouse built as a lean-to on a brick wall
( so as to soak up the heat, and make it even hotter). However, it was a
cool rainy day, and they had doors open everywhere so it was not ( then) too
hot. No humidification apparatus whatsoever.

Vandas hanging up with very good quantities of roots, but so dry they would
snap if you tried to bend them. And a few ( maybe a hundred or two) clay
pots of ex-supermarket mass-produced oncidium hybrids with burnt foliage -
what remained − which at a guess, were last watered in March or maybe April.
Oh dear, oh dear....

The hydroponics consisted of some nice cos lettuce, one to a pot, and some
even nicer strawberries grown is something like rain guttering. And the
gardens were not bad although not really "open-to-the-public" class.

Might save you a journey, this info ...

Hi Geoff,

On reading your comments I thought that this type of information is what this 'Club' is all about. I feel sure that some members may have earmarked this place for a visit, but will now not bother.....well done. It might save them many miles of travelling.

The only good thing to say about Hougton House and Gardens is, that the countryside thereabouts is very nice and some of the views are very good.

Ian Plested's [and my] good friend Rod Malcomber who together founded 'FMS Orchids' many years ago, used to work there. He is a first class wheelwright.

Again, thanks to Geoff for the information. After my visit to the Bath and West Flower Show tomorrow, at Shepton Mallet, I will tell you what I have to say about.....'Marina Orchids'.

Cheers, Rodge.

Regarding the classic orchid purveyors, Messrs. James Cypher & Sons,
can anyone lead me to an article or book that discusses their
history? More immediately, does anyone know when the company closed
their doors? Thanks!

Hi all,

I am back from my day out visiting the Flower Show.

As you can see from the attached photos, 'Marina Orchids' staged an excellent display, for which they recieved a 'Large Gold Award'.

I could see that they did work very hard and speaking to the owner I was pleased to hear that they had took on board comments from previous judges.

I am certain that the general public would have been very pleased with the display. The plants were excellent, all of excellent quality and large ones at that. The foliage and bulbs were obviously treated, maybe sprayed, with some sort of 'Leaf shine', but they did look so good.

I missed an opportunity to have a close look at the plants for sale in respect of one item..............the plastic label which might have told me where they came from, damn! But once again I was a little bit surprised at the quality of the plants. I feel sure that we have all been to shows and seen the benches crowded with plants that were collected from Holland by the owners own vans a few days before. Some of them no different than what we see in Supermarkets and Garden Centres. The ones that Marina Orchids had for sale were a class above the norm.

Looking at their Website, I do not see a listing of orchids that are for sale, but maybe they will have one at some time.

The orchids that were on display and the ones that were for sale were perhaps what we 'Orchid Buffs' might call 'Dutch Imports' or something similar. Nothing wrong with that.

To end up I will say this; Marina Orchids seem as they have a very good supplier whoever it may be and even if they only sell at shows, I think they are on the right track for the future.

Who knows.........David Stead on the way out.......Marina Orchids on the way in.

Cheers, Rodge.

Mtssa Shelob ; impressively big flowers ( 7 inches from north to south) but
I won't boast, having looked it up on OrchidWiz and seeing that some cove
got an award for one with about 42 flowers and buds on 6 or so spikes...

Blc Green Mul − I have been growing this plant for years, and am quite
convinced that this was what it said on the label ; I think it's one that
Paul Phillips imported when he was in Florida. But OrchidWiz and Wildcatt
refuse to know it , and I have searched against all three components -
Green, Mul (or mull) and Orient. Anyway it's a daft name for an orange
cattleya ! But I have no idea what else to call it , except "orange-
perhaps Bc misnamed... any ideas ?

Paph root action − I thought this might be of interest ; potted in Melcourt
bark and sphagnum moss mix. Interesting to see those roots branching like
that ( and another nail in the coffin of "can't grow orchids in transparent
pots unless they are phallies ! ) . I wish I had time to re-pot all my
paphs every six months , it does seem to stimulate new root action.

Lost label. This is a plant factory, oncidium type multi-generic, which a
few years ago everyone was selling. Anyone got it and can tell me the name ?
I am fairly sure that the cultivar name is "Stars and Stripes".

The eria − this was a back-bulb prop from my main plant, just stuck into
Perlite and hung up ( watered, of course ! ) I like the spike habit , but as
you may imagine, the flowers are pea size, if not petit poise size.

Jewel Box − one of the several ( 3 if not 4 ) cvs of Transvaal which I have,
and the only one to flower this year. But the paphs are on the mend, now
that they are in better light ( I find) but another move is on the way
shortly when some new fans have been delivered and I can have a general post
reshuffle − I intend to give everything more light.

It is good to know that about paphs.

I do like the little Eria but I can find no mention of this species anywhere and the RHS don't list it as a hybrid....... Are there any Eria hybrids, I wonder.
