16% is good RH when flowering so why change it.

82 degrees is too hot never mind 86.

RH does'nt matter during veg but it does during flowering.

oh ic well thanks 
any ideas on how to bring the temp down a little bit then? i have 2 fans on the inside. one oscilating back n fourth and the other pulling the air out of the top for exhaust

would widening the intake help it better? i'm in a closet and i can hear the fans going if i turn them up higher =P i'm trying to be all stealthy

if you've got room try a bigger fan ocilating inside. or a quiter fan. or try widening the intake.
whatever you feel will work best.

thanks for the help bro i really appreciate it

What range should I maintain for my growroom humidity and temperature?

Humidity and temperature gauge are essential in any growroom. Daytime conditions should be 70-80 degrees without co2, 80-90 degrees with co2 until the last two weeks when daytime temps should be kept between 70-80 and co2 can be reduced to adjust for the lower metabolism. Night temperatures should be kept above 60 degrees to prevent stress. It is preferrable during flowering to have a night temperature drop of 10-20 degrees to stimulate flowering hormones and reduce stem elongation.
I find that low humidity causes stress on plants. I recommend 50-60% humidity until the final 2 weeks of flowering. At this point, the humidity should be lowered as much as possible to encourage the plant to seal and protect itself with additional resin. (I am able to get the humidity to go as low as 31%) I have been able to frost things up considerably this way. The higher humidity levels prior to final ripening reduce salt levels within the plant tissue and encourage healthy, more lush growth.

Thats the first time i've ever heard that advice... isnt that high RH bad for buds?
No. Vegging should be around 50-65-% humidity when vegging and lower to around 25-30% during flowering for tight buds. I am sure i have some more info on this that i will dig out for you.

good lookin out luda
good numbers to know
do you think that it is the amount of change in humidity that frosts""
for example if the humidity didnt fluctuate as far would the result be reduced or if the humidity was intentionally kept high then dropped be more benificial?
i hope that made sense
any thoughts?

and what about the effects of short term humidity changes?
Not true really, plant stomata close at about 35% to prevent the plant from drying out. This slows CO2 uptake and slows overall growth.
A fan over a bucket of water is an easy fix for low RH.

low RH is good during flowering so why change it. il stand by that comment any day.
anybody heard of budrot.

I've had RH's of 65 to 70% for 3 years in my room, with fans going, and I've never had bud rot. Circulation is as important as RH, from my experience. Not to be a contrarian.

Exactelly with the right evironment and ventilation i have never had bud rot.
