When I stepped in my house I listened for the "Hmmmmmmmmmmmm" from the electronics and I knew everything was gonna be alright. LEDs and soil is so undramatic. I just hear the fan.
Much less heat with LED vs HPS. can get too much light with either. There comes a point of diminishing returns and then there's just way too much where your plants aren't happy. Gotta keep up nutes with how much your plants are transpiring etc...
