Humidity Questions

I just went up and checked on my girls and it was 63f and 83% hum and i am wondering the best way to control it without bringing in cold outside air . I can not afford to bring in more cold air from outside it's 43f outside and it has been getting colder some mornings . whats the cheapest fastest way to keep the hum down . I am 17 days into flower now and don't want to start getting any mold issues . also when lights on hum drops to about 63% . what is the highest acceptable with temps running 77f with lights on . fyi this is soil grow . Its a 10x20 room with big box fan blowing air around and a little heater on a thermostat to keep me at from dropping below 63f . I do have two in line style fans about 170 cfm that i am not using currently due to cold outside air . I am running my light cycle 5pm to 5 am to help with outside air temps .

what about those dehumidifier you see people putting into their RV when they store them the DRYZAIR things ? would that work ? I'll take any advice i can get .

get a desiccant from the store
Yes the thing you mentioned should work
Im not sure how many you will need though
Maybe 4...one for each corner
try and get it at 30 -40%

30-40% at night will probably be impossible... as long as you get it down to 55-60% (at night)

I bought a little one on amazon for 80 bucks and it works for my 5x6 space... mine was getting up to 80% at night and now its down to 60% no bud mold or anything like that.

any chance just moving the air around with more fans in my huge room will lower the hum?

yea pretty much sealed . I am thinking the hum shot up when lights went out from the temp drop . So what I'll try turning up the heat so that the heat stays close to ideal temps during light and dark cycle . That alone should help with the humidity spike ?

its probably spiking at night due to the plants perspiring after the lights go out man... might help but still not enough... =/
