Thank you for your reply and taking into consideration the idea of a veg only light.
I understand that its possible to dial down the wattage, but the light still gives the same spectrum. My suggestion is creating a spectrum of led lights specific for the veg stage.
Currently the HLG B-Spec lights use white 3500k and blue 470nm leds. No other QB grow lights are available in this configuration.
As a temporary solution our veg rooms are using the Maxsison QB lights, which are mostly comprised of 3500k and 6500k leds. Compared to the SF QB line which uses mostly 3000k and 5000k leds. We have noticed our plants in veg have tighter nodes and are slightly taller too when using the Maxsison lights.
@Spiderfarmerled I think you're doing a great job targeting the small/tent growers with an all-in-one light. But for the commercial/medical growers, having veg and flowering specific lights make a massive difference in efficiency.
