Andy,

They look great! I've been looking for a B. tingabarinum. They don't seem to have them here.

The Bulbos are really enjoying the heat , as am I! These two are out
at present and I thought to photograph them together to show the differences in
flower size. I often don't grasp this from separate photos even if sizes
are given , and in my experience sizes are often given inaccurately. The B
tingabarinum, on the left I bought as a seedling several years ago. I
transferred it to a mount and when it flowered one side had orange flowers and
the other peachy/yellow. By that time the clump had a lot of bulbs
and gradually I have been separating the colours.

The second photo is a close up of the orange form of B tingabarinum.
I have been playing with the close-up equipment. Slow work but I am
pleased with this shot.

Thanks Geoff and Esther for your comments. I agree that I often see
details in a photo which are quite beyond my visual acuity and it is one of
the reasons for taking these close shots. It's especially so with
miniatures which are a real interest of mine.

One of the reasons that I photographed these two species together is that
in The Plant List that they are said to by synonyms with B pecten-veneris
taking precedence. Generally I use their list for naming but I can't see
that these are the same species − unless one of mine is mislabelled. I
don't have a key for the genus and I have kept the names under which I
bought the 2 plants. On the Kew database they are listed as separate
species. This even though Kew is one of the contributing authorities on
The Plant List.

So Esther you might find B tingabarinum as B pecten-veneris.

Mine is hanging up high with the Cattleyas and is about a metre away from a
ceiling fan which is on all the time. The thermostat in this house is set
at 16/17 but the sensor is much lower down so it may get a bit more heat.

As for feeding − I always use a diluet feed at every watering. I have just
changed to using Akerne's Rain Mix. For the last few years I have been
using Orchid Focus and I have not been very pleased with that. I think my
results were not as good as when I used Optimum hydroponic mixes. Also I
found that Orchid Focus developed mold in the container and given that I
buy it in bulk I was none too pleased to find mold in a 5 l container!

At least I am pleased to see that a plant the size of mine is ready to
flower. That's the thing with orchids − there's always next season.

Hi Andy,

I found that a local seller has B. tingabarinum! He told me that he's been having trouble keeping them in good condition here, so I have second thoughts of getting it.

By the way, Geoff, I bought a B. ambrosia from this same seller and I'm giving this species another go. Did you get round to smelling the flowers the last time yours bloomed?

cheers,
Esther

A rather different Encyclia − E.brassavola. Growing on a small log − of course !
I have been watching the flowers open for a few days , not sure if they will open further − since they do now look like several of the brassavola species which the flower is said to resemble. Flowers about 2.5 inches natural spread.
This is a piece off the large plant which Burnham have, and you may have seen if you went there at the right time.
I have another example, not yet flowered, which I have been raising from a tiny seedling ; now up to half a dozen leads,, but the bulbs only a quarter the size of these, although they have started producing spathes − but not yet flowered. That one has only just logged on , as you might say, although the one shown here has been on a log for a year since I bought it .

Any of us who venture into the realm of taxonomy and declarations of "this is so and so, not that other, etc" must do so in trepidation.
But I will stick my neck out as far as saying that the plants I know under these two names can be distinguished ; B.tingabarinum has flowers possibl;y twice as big as pecten-veneris ; the latter has fringes which are rather thicker − more like thin fingers than hairs. But then I have only seen one of each, and who am I to say mine are correctly labelled ?

I have seen superb P.godefroyae elsewhere ; one grower who is in a chat group I used to belong to once showed a dozen different, all seed-raised and flowering in about 4 years from flask. Incredible to me ; I i discussed with him. Apart from questions of compost etc, the main difference is temperature. I ended up concluding that if I turned my stat up I might stand a chance of doing the same.
I also remember that way back, when we used Fahrenheit not Centigrade, it was calculated that to turn up the stat by only 5 degrees (not enough, here ), doubled the heat bill.
To quadruple it, is in the no way situation.

But then, I have other chat group friends who drool if I show an odont − they sat .they could not possibly keep them alive , as their conditions are too warm.

The grass is always greener on the other side of the street.

I agree with you Geoff both on the observations of these 2 species and your
conclusions! I am keeping the names I know anyway.

Regarding culture Esther, I see that Siegerist lists it as warm growing and
IOSPE says warm to hot. I grow it intermediate, min 16/17ºc, wet and shady
and it thrives.

Caucea phalaenopsis. A cool-growing relative of the Oncidiums. It doesnt
really thrive for me and is easily overlooked and then it produces these
lovely flowers every summer. I think my cool house is probably a bit too
warm for it. Flowers are about 2-3 cms across.

Masdevallia stirpis I like the form of these flowers. They seem to
suggest movement. The pot is 7cms across which gives an idea of the size.
An easy cool grower from Ecuador.

Phalaenpsis parishii I am very pleased with this − only 3 flowers last
year and here 6 out and 4 buds. Seem incredible for such a small plant with
only 2 leaves. I do hope it's not a bid to set seed in it's death throes!

Schoenorchis manipurensis. This hangs up hgh in the warmer house and it
was only when I took it down fo an all-too-rare inspection that I
discovered that it was in flower. I think the plant itself is lovely even
when not in bloom. The whole thing is only 3 cms across.

Thanks for the culture tips. We can't get 16 to degrees C here without artificial cooling. That's probably why it doesn't do well here.

Hi Esther
I can see the leaves look a bi floppy − bigger than mine though. I like
the comment on your other email about not being able to get the temperature
as low as 16. Here in England for much of the year it costs an arm a and
a leg to get it UP to 16! Far fewer people run and intermediate houes and
I don't think I know any hoppy grower who runs a hot house.
Do you grow outside?

Hi!
I´m using a headlight watersprayer pump (or whatever it´s called in
proper english) from a Volkswagen/Audi in my glass cabinet. It´s 12v and
can lift the water at least 1 metre. One word of caution though, it
needs somewhere between 4 and 5 Amperes.
I think it´s a good idea to avoid 220-230V, close to water. I use an old
computer power supply, to get enough 12 V current. The pumps are fairly
cheap at a junkyard, especially compared to a pump from a garden center.

Building on Tina's idea, I opted for a much cheaper option than a hydrofogger. I purchased a humidifier device from Maplins for just £29. In my 8 X 6 intermediate greenhouse I need to fill that every 12 hours at the highest setting, but even on the hottest days it keeps humidity 75-80%. Mine is not controlled by a humidistat but it does have a control knob to regulate how much humidity to produce.
Being retired I opted for this very much cheaper option while I am here to supervise. When I go away I have some very fine misting nozzles from America which disperse half a gallon per minute from the mains which I set on time clocks.

I have been using an electric powered pump for both spraying and watering for many years now, and would be lost without it.
Mine is a Flojet #lift pump# with a long reach lance connected, supplied by Simply Control. The pump is mounted on the greenhouse wall adjacent to the water storage tanks. It can be used to spray using the lance, or run misters, or remove the spray head and use it for watering. I think these pumps are really for 'clean' water, they dont seem to mind fertiliser being added, but don't seem to like insecticides, especially any of the oily types or any spreaders being added to the water, so I still use a pump up sprayer for these.
I am currently on my second unit, the first one I had lasted several years, and I think my current one is now past its best. I have recently been looking on the internet to see about getting a spare, and whereas Simply Control do not come cheap, at least they supply the units wired for mains connection and ready to plug in and use. I found other suppliers offering similar pumps cheaper but not being at all technically minded I found the specifications confusing, I only found one that appeared to match the spec on my current pump, and it was only a little less than Simply Control, and it would appear to require the wiring to be added.

Thank you for this link to the Watermate pump, useful and interesting.. I have looked at their website, and having a couple of queries rang and got more useful information.
One point I didn't mention in my other email is that the Flojet is a 'demand
pump' as well as a lift pump. ie when the trigger on the lance is pressed and
the lance is open the water flows through and when the trigger is released the flow ceases and the pump stops. The Watermate is not a demand pump, but the man I spoke to explained how it could be rigged up to work in a similar way with my hose and lance. He also said that if it had the 'demand' controls built in it would be double the price, so that made me feel better about the cost of my current unit.
Thanks again, and I hope between us all we have given Andy a few ideas.

Any pump with a 35mtr head is far too strong for any orchid house so simply think about it. If a pump can lift water to that extent then it will blow any compost medium out of it's pot.

Thanks everyone for your input so far. I look forward to your info Geoff
when you get back.

I have been a bit busy with work so have not had a chance to digest it all
yet and I would appreciate any other words of wisdom.

My initial thinking though ..

I think the info on foggers is interesting and I may well look into those
as well, especially as that maplin one is so cheap. However fogging and
spraying mounted orchids is different. Mounted orchids need a soaking and
then need to dry out. If they stay wet all the time they would rot and the
mounts would just get too much moss.

Sheila thanks for the info on Simply control. I don't see it on ther
website but I may phone them. They certainly are helpful. Though I also
think they are over priced. I have had their heaters in the past and still
use one. However the thermostat went so I returned it and had the
thermostat replaced. It went again pretty quickly and I decided to buy
another external thermostat. So pricy and not terribly satisfactory. On
the other hand I have a Parwin heater which I have had for at least 20
years and it is still going strong!

There seems to be a wide range of small pumps on the market − for window
washing, caravans and various other uses. Some of these are demand pumps
and they don't cost 100s of pounds. However I don't have the expertise to
work out the pressure requirements. I certainly don't want to blow the
compost out of the pots or the plants off their mounts!

More to do on this one....

I have a Parwin heater which I bought in 1981 and it is still going but unfortunately the company is no more. By far the best electric heater for greenhouses (my thoughts but you may disagree). I only use 2kW and take one of the bars out, which is a useful factor. I just give it a good clean and oiling every year. I don't use the internal thermostat as not accurate enough. I use a Two Wests Electronic thermostat.
