How big of an issue is light? HELP
How do you know whether to raise or lower your lights? My LED is pulling about 250watts from the wall... Box said keep light 30" away during veg... But I'm not so sure about that. Thoughts? How will I know if it needs more/less light?

Viparspectra P2000 height and intensity
For those that have experience with the light I'm using, Viparspectra P2000, how high and what intensity percentage should I have it? Currently I'm at 21" at 75% power. Also, I run it 24/7. I have an app on my phone and it says my DLI is at like 56 which seems way too high.
