100w LED distance??

So I'm having a tough decision here. First time using an LED and also first time doing a micro grow. So far the plants and I love the light, but as they get taller I have a problem.

It is currently about 10-12" from most of the tops, with a couple branches closer to 7-8" away. No light burn anywhere, but I am getting a more uneven spread as the plants get closer.

Do you prefer to have a bright spot in the middle with dimmer edges, or is it better to raise the light some until the spread evens out some? I'm guessing that as long as I'm not burning, to just leave it. I think raising it may even out the over

all spread, but also decrease overall intensity.

Each plant and each light will give different results. The best way to know for sure is by watching the stems of the plant. If they get too tall and lanky lower the light and if stay short and get squatty raise them. Watch the plants they will show you where to put them.

Most people have their lights too low or too bright and intense which causes problems so they add a lot of cal mag. I like to raise them as high as I can to keep from having to add a lot of cal-mag. Cal-mag tastes bad when smoked in flowers.

I run several single Boards 100w to 110w and try for 14” to 16” average over flat LST canopy. If I get closer plants get light burned which is much different than HPS burn which is heat burn mostly.
