I have 2 gavita 1700e's in a 4x8 tent, with the lights as high as they will go. I also have a controller EL2 connected, dimmed down to 50%. I still think I'm getting too much light. Is there any way that i can dim the lights a little more? The par or ppfd at the canopy is at 350-365. It seems to be a little too much for young plants. The light is 46" above the canopy. Am i out of dimming options? thanks
