I get the deli cups at a local restuarant were they serve sour cream, salad dressing, and salsa in them. They hold about 2oz. and have a clear lid which makes it easy to see the seeds floating in the water and I don't have to worry about knocking one over and spilling it.
Mabudon, I used this method on the last batch of Darlingtonia seeds I tried (Thanks Stormbringer!!) and had about 95% germination. I've tried Darlingtonia from seed two other times and got zilch using the "sow them on the media" method.
