First run with LEDs and also have a PAR meter. My question is I'm pushing close to 1000 PAR on a lot of my canopy. I'm not running co2. The plants seem very happy and no signs of light/heat stress. So my question is do I reduce the intensity simply because I'm at or near the magic 1000 number most say to stay below without co2 or do I let the plants speak for themselves and guide me?
