slow growing

[ibadreamer]

i have recently started a winter garden. i have planted spinach, kale, beets, lettuce and carrots. i planted the first batch about 7 weeks ago. then another batch 2 weeks later. the first batch is only about 3" tall so far and seems to be growing real slow and the same with second batch. i live in so cal and the weather has been cool. the seed package for the spinach said it was like 60 days. mine will sure not be ready in that time. what should i expect for growing time? thanks
