ok so with my light running my humidity is 50-55% and temp right at 80F...but when the light goes off the temp falls to around 73F and the humidity up to 66-69%. The highest it has gotten is 77%, it was raining and humid as hell outside..so i need a simple and hopefully natural way to drop the humidity once it starts getting out of control..?

Appreciate any advice:leaf:

it is 3.5'X2.5'X8'..400 watt mh for veg and i have a nine inch exhaust fan at the top blowing back out into the room..i made this setup real cheap just creative..there is a gap at the bottom where the exhaust fan is pulling fresh air in from. yea the fan runs during the light period and off during dark. soil grow

tried that and it would only drop to about 60% i live on the border of east and central tx so it is humid as hell outside pretty much all the time. i was thinking that the heat from the light was the only thing keeping the humidity down..what if during the dark i put a small heater and run the fan to keep the temps up or would this cause stress from no temp change?

run the fan all the time or put it on a seaperate timer to come on a couple times during the off period

This is what I do...but I live in California so it might be different...I need to get a humidity tester now but my temp is usually 73-78 for my one plant so I really do not think i need one...:eyesmoke:
