I had one bad experiance with pre cooled bulbs.
I had purchased them from Ednie, (where Sunshine gets theirs from), and planted in late fall. Maybe about three years. I had no problem, the bulbs sprouted the following spring.
But then one year we had a warm late fall, and the bulbs sprouted in the fall. The next year nothing at all from them. But then the following year many of the bulbs came back. Some did not.
I think the pre cooled bulbs are meant for the cut flower industry, so flowers can be grown and sold all year to florists.
But, I'm no expert on it.
