Drywall Ceiling span

I am drywalling a basement ceiling and the span to cover the ductwork is 29". Is there danger of the drywll sagging with a 29" span?

Drywall Ceiling span

Just use drywall adhesive, more screws and 5/8 sheetrock.

Drywall Ceiling span

Can you span it with flat 2x material first and then add the drywall? Gonna lose 1 1/2" of height but 29" is starting to get out of my comfort area.
