could anybody tell me the best rh% to have in the late stages of flowering
im at the end of week 6 and im watering every day (water only from start of week 6) last week my humidity was from 30%rh min max 46% i know its best to keep it under 50%rh but for the last few days my relative humidity has'nt been going very high maximum 27% rh and all last night its been really low at 18%rh to 21%rh and im not doing anything different.
is a low %rh good or bad?
why is it going so low or is it best to be low could somebody please explain to me whats happening or even a little about adjusting it cheers!

SORRY! IM ALSO GROWING IN SOIL IN A 3FT X 4FT CLOSET WITH ORDINARY CEILING EXTRACTOR AND THIS IS WITH THE LIGHT ON THAT ITS 18%RH to 21%RH WITH
THE LIGHT OFF IT RISES IS THIS CORRECT? AS I THOUGHT WITH THE LIGHT ON THE HUMIDITY WOULD GO UP BUT MINES IS RISING WHEN THE LIGHT IS OFF. ITS AT 25%RH
AND THE LIGHT HAS BEEN OFF FOR A COUPLE OF HOURS.
ALSO SHOULD I KEEP THE FAN ON WHEN MY LIGHT IS OFF??

yeh keep the fan on just to keep fresh air circulating,you dont want the air to get stale in there!low humity when flowering especially towards the end is much better than high humidity so dont worry about it!
