I live in a subtropical area.
Short answer: YES!!.
I now religiously use a filament dryer, VAC bags and loose silica beads that I bag my self into DIY teabags and then redry in the oven.
I also make sure to dry new filament for 24hours before using it the first time…
Since I started doing this for PLA and PETG, many of my previous my print issues dissapeared…
BlazeCut Tseries 50cm is about right for a 3d printer enclosure volume.

Prusa sells a 30cm one as an option for their enclosure, but it is undersized for the enclosure volume, so I bought the 50cm one separately.
