[pleurothallid-l] humidification systems

If  you are trying to grow pleurothallids in Florida you are a braver
fool than I!  Just kidding.  Actually, I know others who do a great job
of it down your way.  And heat can be nearly as big a problem up here in
the summers too.  One thing I have started doing here for heat is to
move most of my cold or cool growers into the basement during summer.  I
have a large set-up with multiple levels, lights, etc that gets things
through our summer heat.  Unfortunately, a basement is a rare thing in
Florida.  My thought is that if I can get this humidity thing licked, it
will also help in cooling, at least when the ambient humidity is low.
I made a make-shift evaporative cooler at one point and used this in my
growing area.  I built a frame out of wood (about 3 feet wide and maybe
6 feet tall).  I had a 5 gallon bucket of water with a small submersible
(pond) pump in it.  This pumped water up through tubing and into a piece
of PVC pipe running across the top.  The PVC pipe had holes drilled in
it so water would drip down.  The water then passed over two aluminum
filters - I think these were for a furnace, got them at the hardware
store.  The water was then collected in a plastic tray under the wet
pads where it was directed back into the bucket.  I set up a box fan
behind the wet pads.  This circulated air through the wet pads which
then cooled and humidified the air.  It worked fairly well, but am
looking for something that is a bit more sturdy and reliable now.
Things started falling apart after a couple of years.
Oh to be one of those lucky growers over in the Pacific northwest or Bay

Hello Tom,
            I live in balmy Florida, so humidity is not as big of an
issue for me.  Heat however is a problem.  I have noticed that I can
keep some less-than warmth-tolerant orchids alive by keeping them in
dishes of water during the summer.  My pleurothallids actually sit in
little lids of water for most of the summer.  It sounds odd, but it
works.  In the winter of course this method is discontinued.
Pleurothallids do not like to have their feet wet if it is cold outside.
(Some rotted pleurothallids in my collection will attest to this
statement.)  In the winter, it is very dry here.  So, I let them sit in
water for a few hours in the mornings.  This little trick has been
successful for the year or so that I have grown pleurothallids.  I wish
you luck with the humidity issue, it is a difficult one.

Hello out there.  This list has been incredibly quiet lately.
I am trying to improve my growing techniques by adding some form of
humidification to one of my growing areas.  I don't have a greenhouse.
I am growing most of my things in what had once been a porch, but is now
glassed in on three sides.  This is connected to the house and is
roughly 250 square feet.  I had considered buying something that I think
was called a hermidifan, manufactured by Jaybird.  Unfortunately, they
seem to have discontinued this.  The smallest unit they now have is the
Aquafog 400.  (I think they must apply model numbers by the price!)  My
one concern about this is the potential for noise.  I have been in
greenhouses that use some of the larger units and they are very loud.
Is anyone on this list using one of these?  If so, how do you like it?
Any suggestions for other humidifying devices that might work well?  As
an alternative, I was also considering installing one of those smaller
outdoor stand alone evaporative coolers - they look something like an
air conditioning unit (I saw these on almost all the roofs of homes in
the Salt Lake City area a year or so ago.)
