Amazing, when you follow the directions it seems you're more apt to succeed. On day 6 at 100% humidity and an average 76 degrees temperature, the impatiens started to sprout. If you look very closely you'll see a radicle emerging from the seeds. I had to use a visual aid to see the sprout.
The camera at close range shows the seeds if you know what to look for. I must admit, it's a bit like finding Waldo but they have definitely begun to sprout.
