Drywall ceiling in basement

In a room I am finishing in the basement, I am building a tray ceiling around the entire room, 1ft down from the ceiling and 2ft from the wall. Do I need additional support for the drywall on the under side of the tray? WHat I had read indicates that 5/8 in drywall can span 24 in but would like to confirm. Thank you

5/8 drywall can span 24". Any supports would be there primarily to help keep it running straight.

The thing you would need if the wall isnt fully drywalled is fire blocking in your wall 1 ft down. Otherwise a fire in the wall would jump into the soffit and up into the floor joists.

But, you still have to construct the tray structure, so just make it 16" O.C. so you dont have to deal with two different thicknesses of drywall, overall it will be a simpler project only having to deal with one!

Thanks for confirming the dry wall question. Where would I learn more about fire blocking? I can understand the need. just don't understand how it is done.
