I've done several grows and side by side experiments with LEDs (not the blackstar brand) and I've found them to be great at vegging. They grow fast, with very close internodal spacing. You have to use the blue LEDs for vegging because the red ones are not the right wavelength for it.No, not from my experience, Using a blackstar 240W led, there is practically little to no growth,
