Thank you for the tip and I had a feeling the 600W would be too much. Im knew to this page, my lights I got from Vivosun and the only thing shows is the Voltage which is 100-240V so i kind of guessed the Watts lol but i do also have my plants that are growing under right now at 12 on 12 off and they are doing perfect but also thank you a second time bcuz I just was asking questions about auto flowering and my next one was what size pot should I start off with once ready to plant so your saying the auto flowers need to be in a pot bigger than a cup?
