What heights are you guys running in flowering? I see some of you so far away. I keep mine 8-10” to slow grow in my DWC. They get so huge fast.

To find the optimal height, you need to know the ppfd footprint of the light.
Edit: also read your plants response to the light.

Can’t you turn it down? My Timber Lights say to run 25% to 30%. I have been running 80% with zero issues.

I didn’t ask for optimal height. I asked what you run? The reason I ask is I have always ran my height and saw some people running leds at the top of there tent or room. I’m concerned if I ran that height they would grow too fast and I would run out of room.

I could've turned it down if I had connected a pmw to the meanwell driver., but I was a lazy man.

Shit, my bad. I was sidetracked as I read your post and just replied. My lights are currently 16” above the canopy. Bringing them down a little each day to find the current sweet spot.

Do you think it will grow faster if I raise my lights?

Optimum distance is defined by your light. You can generally get closer with lower wattage lights. A Mars TS1000 (150w) has a sweet spot of around 14". A more powerful light will generally need to be further away. The new bar arrays are an exception as they can get quite close (<10") because the light is spread out over a large area.
