The Summer White strain is great for me because it fruits in summer when most other mushrooms are scarce.
I would try to inoculate as soon as possible to take advantage of the mild temperatures and fall rains. You don't want your logs to dry out at all or get contaminated from spores floating around. But normally I do spawn runs for mushroom logs in the late winter inside large plastic bags to keep moisture levels stable and temperatures between 60 and 70 degrees. But it's more important to have clean logs. Also- I always avoid grain spawn because it is like candy for rodents and they will stop at nothing to eat it!
