since you are into flowering just make sure that the fan is in constant operation.....mold is generally created when the air does not circulate.....if you have a good airflow then you will be fine and no mold will appear anywhere.....the first signs of mold will be in the upper corners of the walls into your growing room......i still have the spots (mold) as a result of the elevated humidity rate during vegetation.....thanx to better airflow and a window wider open during flowering the humidity dropped and the mold stayed in there and did not spread anywhere else....see the pics.....hehehe....lucky huh? i did not have any organs to measure anything else apart from a mickey mouse thermometer to check temps.....lol
one more thing i noticed is that if you have good ventilation, exchange of air, the smell of the plants is reduced somehow.....if they are closed with no fresh air they stink.....has anyone ever noticed that?
