[LuciferN]

hey people, dont mean to be disrespectfull but im only looking for advice from hardened growers who know their shit. hey people ive constructed my room and everything is ok apart from the one problem i have my room is sealed air tight with fresh air comeing backward and forward my exhaust is 12" with carbon filter running all the time with enviro temp controller during the day humidity is fine between 38 -58 no higher BUT when brights out it raises to 68this is bad guys i think. why is this and how can i remedy the situation ive a fan heater on to keep the room warm and a fon blowing air round ect my exhaust runs 24/7 just to be clear
nuf respect

Well 68 is quite high it could lead you to some problems, pest, mold etc...
Where the air is coming from ? What are the temps usually ?
I guess the humidity is higher when light are out because there is no heat produce by the light to dry it. A simple dehumidifier running only on dark periods might solve you're problem...
