The Cannabis Cultivation GrowFAQ - The Internet Hub for Marijuana Cultivation - What range should I maintain for my growroom humidity and temperature?

Quote:

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.

Is this sound information? I thought the RH was suppose to be lower even during early stages of bloom, and have already added a dehumifier to my cabinet. Right now my RH is at about 38%. Is that a good/bad level to be at? should I get rid of the dehumifier until the last two weeks?

in my experience you dont' have to worry about high humidity until about 4-6 weeks into flower... when the buds start to get full and tight if you don't get that humidity down you will get mold and jack up your harvest.
Tempeture I think is less important that humidity.. that has been my experience.

cool, well I had my RH% down to like 35% last night after only running the dehumidifier for a couple hours at the most, So I think I should be ok when the time comes.

I know zandor from the grow report says in the final weeks you should get it as low as possible, this will encourage your plant to seal it self up with lots of resin.
