Thank you for the responses. I appreciate all the advice. I had a bad day at work yesterday (well they are all bad but this one was worse, I digress...) so I took this little disappointment larger than I should have.
After sleeping on it I decided to pluck out the sprouts and pot them up, all of them in vermiculite, not just the pulsatilla.
So this morning I potted up 5 purple Pulsatilla, 4 Red Pulsatilla, 15 Digitalis obscura, and 4 drumstick allium. Since there are more seeds in the containers I stuck them outside with my regular wintersowing containers.
On one of the red Pulsatilla I put a fine layer of chicken grit. On two of the purple Pulsatilla I put a layer of small rocks. The rest are just potted up in with naked tops. I moved the Pulsatilla to brighter light but in among other potted houseplants. I will gradually move them to bright full sun. I can't do anything about temperature.
So we'll just see what happens.
Thank you all again.
