40-50% is optimal, so I am a bit concerned about my levels. With the lights on it goes down to about 61 but they are getting to like 68-69 with the lights off, definitely some cause for concern.

I know some people ahve to be using d/h in their rooms even with powerful fans, curious what the results are. If I can bring it down a good 10% I am going to go for it.
razzapiggy Reviewed by razzapiggy on . Humidity Question Just got my humidity therm. hooked up, it reads 66 but the problem is it's not right where the canopy of the plants are. I see no signs of fungus at all, but am considering buying a dehumidifer as a precautionary measure. Question is... if my humidity is at 66 a few hours into their "day" what does it get up to at night? Should I be concerned? I also only have one occilating fan going right now, perhaps I should buy another. Some people reccomend using a heater during the night cycle, Rating: 5
