RH in dry tent and dry time??

I am using my grow tent and fans as my dry room. I have the exhaust fan running constant and two small fans blowing.

Right now it's 60F and 70% rh.
That's probably about as humid as it will get since the weather here is soon to dry out after the El Niño downpours we've had.

What's an ideal humidity for a proper dry?

I have read 6 to 7 days is ideal.

My last dry was only 3 days but it was under different warmer circumstances and lower humidity.
Thanks

Well you want a final cure humidity of ~ 60%, so it would make sense if RH is in that ballpark range. With a tent a dehuey is a must IMO. 70% is too high.
