Low Humidity?

In Jorge Cervantes' Medical Grow Bible, it says the recommended RH level is 40-60%. Is there any downside to having RH at 20-30%? I really don't want to add a humidifier to my room to get it up to the 40-60% range. Thanks for any help you might be able to provide! :jointsmile:

The plants will want too drink more H2o then normal. Too compassionate for this lower the PPM on your feeds and give them more water each time. Other then that its not that bad for em.
