Dense packed cellulose can be installed at any time. It is packaged in plastic bags at about 8-10 lbs/cu-ft so it is dry and protected as prepared at the plant. The bag gets opened and the cellulose is packed into the walls a few minutes later. No time to pick up any humidity. If you are worried about moisture in the wall cavity and wood, don't be. A nice property of dense packed cellulose is that it can take up moderate amounts of humidity and release it over time.
