humidity?

i have seen that a good temp range for cannabis is around 70-80 degrees F I cannot seem to find anything about humidity? what would be ideal I am running now at 75-80 degrees and a litttle over 70% humidity is this alright? if not what should it be?

how old are your plants...What stage veg/flower

my plants are about 2 weeks into flowering and they aside from a few light burns not too bad only cfl's for now they look very good the reason this question is just coming up now is i added a heater it was a steady 62 in there prior to adding heat which, with all the uncovered buckets of water right next to the heater has brought the humidity up a bit. Just trying to get it right this time.

50% is right where you want to be. Raising the temperature will not necessarily raise the RELATIVE humidity. Warmer air will support more moisture. You will need to check it with a hygrometer. There are thermometers available that have hygrometers and will also give you temps in two differnt spots along with recording the minimum/ maximum temps. About $20.00. Oh yeah it tells you the time too. VV
