Not all plants react like that with low RH. Drinking water and taking up nutes are dervived from a ton of variables. Water temps, and room temps, water ph, and ec, are more of a factor than RH.Mine didn't do well with that low of an RH. The plants drink more water and take up more nutes than they should. As long as you compensate then your ok. Mine burned badly. Get a cool mist humidifier
