I tried/use led and they’re fine, my flowering room went back to hid pretty quickly....
I do use them as supplemental light all over the place and over clones/seedlings/moms. But all my main light for flower is hid, whether de hps or cmh. I have one space with a 315 cmh with 4x150 watt 4000k supplemental leds. However, In my main/big space I’m running de hps and cmh combo. No leds in there at all. And I have a pile of quantum boards/cob lights sitting around, de and cmh combo sort of kills it. There aren’t a whole lot of lights that put out as much par as a 1k de. Leds are cool....but not that cool...yet. I think most hardcore led guys here went straight to led. Or moved from flouros/low power hid(400 or less). Contrarily, I think most the guys that hate on leds, tried blurples or the panels that claim 10x watts they actually draw.
Both lighting types work and have benefits and drawbacks. Use whatever works for you, it’s not better or worse than what works best for someone else in their situation/environment.
