I have enjoyed your flasking WP in the past and I have it bookmarked.
Must check it out again soon.
Not sure about these two cute little species as I have only recently
acquired small pieces of them. Maybe they are more difficult to
flask than what I'm used to. Hopefully you will get some other
feedback here. I have raised hybrids with them as parents and
M. strobelii is a xanthic or yellow albino and when put with certain
other albas or oranges has made some striking hybrids like Angel
Frost (x veitchiana) and Kabouter (x macrura) which produce a
percentage of pure oranges or yellows with white hairs and no
M. glandulosa seems to be a "flowering fool" and when crossed with M.
strobelii makes that wonderful hybrid Confettii which covers itself
with flowers! Try remaking it! I must get a piece sometime.
I have tried the two packs of nutrient agar you mention and they seem
OK but I usually fall back to 1/4 MS with charcoal which is pretty
similar. Needs to be pretty soft. Leave some rinsing water on top
when you add the seed. Masdevallias seem to like being replated
often. Before they give off brown phenol stains on the agar. If
that happens you can almost throw them out! I add a little sterile
water on top when replating too to keep the agar from drying out.
Interesting that you like using coconut milk. I don't use it because
it often caused lots of proliferation for me with various genera way
back in the past . I'll do some comparisons. I'm always trying to
improve my media. I presume you leave the charcoal out when using
coconut milk? There are some good medias around but they are
expensive by the 1 litre pack compared with making up your own.
Another month or two on the shelf on a slower media in flask doesn't
worry me too much!
I can't explain why your strobelii are growing in fits and starts.
Probably associated with pH dropping. Try putting some on fresh
media. You should see them take off!
