here's the method:
there ia an old way you may try as an experiment that is using 1/2 a banana mashed in a sterile bowl heated & put in a sterile jar put a nail hole in the lid & fill that with the cotton from a cotton bud wet with a fungicide . when the banana cools sprinkle seeds on top ,replace lid & PRAY. keep in a warm medium light level area & wait .orchid seed is not viable for long as it it is very fine & carries no food source
sadly i think they're all dead (by i think, i mean i wasn't completely sure what they were anyway), the banana has gone cloudy and formed a skin, a bit like the agar jelly at school when it goes bad.
