Hi there having a wee bit of a problem with heat in my grow room since changing over to HPS from CFL it is sitting at above 90F when the lights are on and the extremely rare hot weather we are having just now not helping high 80's for my fresh air intake. I have a 5" intake fan and carbon filter in the attic pumping cool fresh air into my grow room.
I also have two medium sized desk fans in the grow room one which I have set at full speed between the lights and plants the other I have running a bit slower and is set to oscillate to circulate the air around the room. Because the temperature is so high it is also obviously making the room very dry and not humid at all I have tried leaving water in a glass in the corner to try and add moisture to the air will this help ? really cant think of anything else I can do. I also have a 6" fan and carbon filter drawing the hot air out of the room and being pumped straight out through the roof, on the opposite side of the roof I have the intake taking in fresh air through a carbon filter.
The attic itself is not that warm either you can feel it is much cooler than in the room. Are there any tricks or advice on to how to lower the temp and raise the humidity ? Any help appreciated here are some pics of the flowers so far :
