20 to 40 is good (ok) under 35 is better my last grow I kept my humidity at 33% but ideally for dialing everything in where you keep it depends on your temps, in my case the choice of 33% was based on my temp of 72F which gives a heat index of 76.5 (you can google a heat index calculator, I gave a link in the class I taught here to my fav, think it was the second one that came up on google)
You want a heat index that is a few points higher than your actual temp without going over 78F, if you dial things in using this info your plants will thrive and love you, of course this also depends on having the lights set right as well
All explained in my class, first 40 pages of my NooB Advice thread

Ah, will check it out. Thanks.
- My temp is around 75-76F 24C all the time, and its always 20% like a clock..
But, I "obsessed" that the Babes are doing a-ok... So, If you was me, get a wet towel or something to get it to 30-40% or?
They look great atm, 6Weeks, and 3 days into flowering....
In short, If you was me, then what to do?....

Your good but could be better, if you look at the heat index, here is the link http://www.easysurf.cc/cnver16.htm you will see that with 20% at 75 or 76 the heat index is just slightly above your actual temp and since your humdity is solid I would lower the temp to 73, looking at that you'll see it give a heat index of 75.18 which would put you in that ideal place
what's cool about the calculator as you can try different variables to see what works best and like I said any numbers that give you a few points above actual without going over 78 is golden
check out the class to learn how to dial everything

Not true, with his current temps that would slow transpiration and growth, the method of adjusting that I have shared assures optimum stress free transpiration and puts em in that grow like crazy mode

No not magic, it is the number not to go over as with late fall when actual harvest happens in mother nature the temps are dropping and are never in the 80's (mostly, wierdness happens every once in awhile) actually low 70's is best
Thank you.....

Here's my two cents on the issue of humidity. I wouldn't want humidity over sixty percent when flowering, especially if the buds were dense. I personally think twenty percent is to low it tends to dry out your leaves because with that low a humidity you are going to need more water with that amount of transpiration and most people do not water enough with low humidity. Humidity really only becomes a problem when it's high and there is a lack of air movement.
