low humidity levels...

I just started my grow room about 2 weeks ago. I've got a 600hps with a full on portable A/C unit. The babies are looking beautiful and are growing stronger everyday. But my concern is that on my thermometer it states the humidity is at 25%. All the threads I have read say it should stay at around 50% during vegetation and can drop to 30% while flowering. I only hear people worrying when the humidity is at high levels. Is it bad to have the humidity at such a low level? How can I raise the level of the humidity? I've tried doing a few searches but only find information about high humidity...not low. Any advice is greatly appreciated! Thanks! :jointsmile:

You're right - it is a bigger worry to have high humidity rather than low; especially in flowering.

If you are worried about your humidity, try to get some more moisture in the air. Leave a tub of water in you grow room with a large surface area. This will help water evaporate into the air, increasing humidity.
