I tend to think trying to do this in Seattle this May counts as a cold treatment!
This thread has been great, I had bought the seed, my mom brought me the milk jugs for "late winter sowing" which were promptly destroyed by the dog, so I ended up with nursery trays and plastic tops. Nothing to take photos of yet, except me pouring the rain off the lid.
I had no idea 300 seeds could be so small and hard to plant! I love the amazon link, that might be next years plan.
