I know typically seeds are started 8-10 weeks before the last frost but here in Denver I don't have tremendously long warm growing time as last frost could be late May and the weather starts dropping into too cold temperatures by the end of this month. I know this is a little too early to get started but how early is too early? Aside from having to deal with the occupied space of a lot of plants, are there any drawbacks to starting off the plants in early November instead of January?
