Hi just purchased the mars hydro FC-E4800, just wondering if the chart they provide for distance and intensity is accurate and should be followed as I was doing some research and found some slightly different distances for the different stages. Thanks for your input in advance! light intensity chart.png

It takes some trial and error, but in general when you first get a new light, start conservative. You can always lower it or increase the %, but it's much harder to bring back plants that got fried from too much light.

Okay thanks, makes sense. So would you say those given distances look good or should I go a little higher?
