Hey there again!
I have read multiple times people saying that more than 50-60% of humidity would make PLA almost unusable after about a month.
Slight problem tho: the average air humidity in my house right now is around 65-75%.
I know it’s bad, but I would like to know if there’s any way I can still print.
I haven’t yet opened the filament, it’s still in it’s original packaging. Should I order and wait for a dryer/dry box (I’m certainly gonna do it anyways), or can I already start printing?
Thanks 
I don’t have the answer to your question but a few ideas to think about.
We use these vacume sealer bags to put rolls in when not in use for a few days. Inside put a small bottle with silica gel desiccant. It doesn’t remove moisture from the rolls but it will keep any more moisture from getting in.
You can find these bottles to print online.

If you have one room in the house where the rolls are stored consider getting a dehumidifier for that room. It keeps the room 600sq. ft. less than 40%.
Thanks a lot!
