This is my first grow in a 4x4 tent they had a rough start i didnt have enough hum.it was down to 35% from running the heater they started to dry up .so i put in a humidifier and brought it up to 70 % now they r 2 weeks old and. Looking great .....it is cold here at night down to 35 to 45 ° so I have to run the heater.
I just went to 18 hrs on the lights from 24.and just started giving them nutrients .
