Thanks..yes 81 with lights on..im thinking plants and such should raise humidty as well
Ok..sorry with lights on temps are 78 to 83..with humidity i just put small cup of water with towel in to wick water out,to increase humidty?
Ultrasonic humidifier(s) can probably solve your problems. Top fill with a capacity of around 5L is best.
As the humidifier fog evaporates, it will also cool the tent a couple degrees.
