David,
That is a beautiful Asctm. miniatum...and to have it blooming this time of year in the northern hemisphere is quite a feat! Bravo to you!
For Nenella...vandaceous plants (and this is one) are all heavy feeders as well, all year long. Besides plenty of sunshine and water, make sure you fertilize regularly...all mine get fed every week.
For Mr. Tech...most orchid seed can be stored for about 6 months; however they do loose viability the longer they are stored...have you tried germinating in sterile enriched agar? It is readily available in the US, but I'm not sure about it in Hungary.
I hope this helps, David
