How much light does a seedling need?Is there a limit to what it can use? Could an LED grow bulb a couple inches away provide enough light? Up to what age? Thank you so so much. My first grow and I really appreciate it!

Full spectrum or all red grow light?Hey guys!
I have a Fast Eddy CBD autoflower grow on its 6th week and in full flower. I have been using a 150W UFO full spectrum light in a bucket, but I have another 150w UFO light that is all red. So my question is, would it help or make any difference if I changed it?Setup. Strain - Autoflowering
