Is it absolutely necessary to have a dehumidifier in an encapsulated crawl space?

How may and what style vents.
Is the grade lower then the outside grade.
Do you have gutters. a grade outside the runs away from the foundation not toward the house, no mulch piled up again the foundation and no flower beds forming ponds for water to lay in up again the foundation?
is it just me. or is these comments totally useless.
encapsulation -- it means no vents
6 mil plastic -- not approved as a vapor barrier for a crawlspace floor 8 mil is minimum and ususally you want 12 mil. if people go into the crawlspace more often use 20 mil
