Hi Ron

Thanks for your answer.

I´m glad that you enjoyed it. The last 3 days I spent at a school located
close to Salzburg (Austria). This school organizise frequently different
courses for their students. One of this courses is our "orchid in vitro
propagation course". It´s always great to see how motivated those kids are
when they are working in vitro ;-)
Now, I have a little bit more time and I´m planing to create an update of
our website.

Masd. Confetti is really a great cross. I´m planning to remake it as soon as
my strobelii starts blooming. I hope that my glandulosa blooms at the same
time (or earlier) to use it´s pollen to transfer it to the stigma of my
strobelii. If the pollination is sucessfully I can send you some seeds.

Thanks for sharing your recipes ;-)
I will try to replate my Masdevallias more often.

I found out that our seedlings grow faster and look healthier when we add
10% coconut water to Sigma P6668 (contains charcoal).

No, I just add the coconut water to the charcoal containing P6668.

I have to buy the coconut water in small cans at the super market because
the coconut trees do not grow here in Austria. Here is a photo of the cans I


This clear water is from green nuts.

A few months ago I started an experiment to find out if sphagnum moss can be
used as a substitute for agar-agar. I cutted sphagnum moss into small pieces
and soaked it with P6668 (without agar-agar). Next I sterilized it and
replated some Masdevallia seedlings (germinated on solid P6668) to the P6668
soaked moss. After a few weeks I noticed that this seedlings were bigger
than those replated to solid P6668.

Thanks for your offer. I would be happy to flask them :-)
Normally it is no problem to ship dry seeds in a standard envelope to
