60% is a problem imo, breeds molds and other crap im trying avoid. im in flower 4 weeks in. i know i need a dehumidifer im just on a low buget. im going to try the dry seetin on the ac and build a vented box for it. my garage is attached also. thanks
60 is the HIGH end of the scale, about the only time you want 60+% RH is when cloning and first few days of seedling germ./preveg... the range you wanna stick to is 30-50%, should have little if any to NO problems if kept in that range, 25% or below will stall growth 55% and above consistantly will deff. invite mold problems.. like the dreaded green mold on soil or the unforgiving powdery mildew.. you might of not had problems in the past but that doesn't make you immune and trust me loosing anything due to high humidity is a shitty way for them to go since it can be prevented early on it with simple measures IMO... Increasing your vent is the easiest way to bring the RH down a good 5-15% which can make a world of difference... more than that would prob. require a dehumid.
60% RH is high for flower. I'd shoot for 30-40% RH
Good points Deoxy points well taken.. obviously losing everything would be a disaster on epic proportions i think in the future i will keep my humidity down below 55% at all times
thanks man

EDIT: My vent system is a beast the centrifugal fan i have could vent a room 3 times larger in under 5 minutes. Having a good vent system only helps so much tho when it starts to rain. Thats when i have the most problems controlling the climbing RH. An oil column heater works very well but i think ima have to invest in a dehumidifier also.
Really 60% breeds mold and other crap? Is this actually scientific fact or is it just something u heard? Or is it from your own personal experience?
Im not trying to get smart or anything its just im in week 8 of flower with some big colas and im regularly at 60 - 65% relative humidity when the lights are off.. When lights are on its between 40% - 52%.
What do some others think?? this has got me ever so slightly concerned.. From all previous experiences ive only ever had one top start to rot on me at the very end of flower. This was in a room full and i removed it immediately before any bad spores or anything could spread. Seeing as it was an isolated case i never gave it much thought or concern that the RH being at 60 - 65% was a problem..
Thoughts please guys??..
