Doubt it. You're inside, humidity is probably fairly stable due to the AC (you do have it inside, right?)
Humidity is an issue when the filament has had time to sit and absorb moisture from the air, all plastics do it to some extent. They sell driers, or you can make one which would certainly be in your capabilities. Certain nylons can absorb as much as 50% of their weight in moisture, if I remember properly.
Do you have any filament retraction settings enabled? It usually helps me with stringing.
