humidifier is the way to go. get your humidity to 50% and make sure you have good air circulation. Also another thing that we did that seemed effective was cut down on outtake. The fan would run for 1 hour near the end of the 12day cycle. Tempeture changes can drop and raise the percentages. before our room got adjusted, lights off was 55F 80humidity / lihts on 75F 35 humidity. But with a heater on timer at night and humidifiers rocken the air, you should be good.
