If you don't want to bother getting it flasked some how, if you have a greenhouse or live in subtropical parts of Florida, then you can spread the seeds into other orchid pots, preferably ones with finer media. If you live in FL, try taking some and sprinkle it into mulch or humus... remember where you sprinkled it, because I was once ripping out Dendrobium seedlings thinking they were weedy grasses...
I would suggest getting it flasked, just to start growing plants still in vitro... it is sometimes a challenge.
