No sucj thing as full spectrum lighting with LED unless you're emitting every single wavelength. Even white light from LED is not full spectrum.

The Martian Method basically uses IR plus red to stimulate the Emerson Effect.

With LED the IR diodes are NOT needed because a proper LED panel, by its nature, already emits 720-1,000+nm IR. Every visible spec sheet only ever lists 400-700nm and won't go past those, but a proper emission analysis shows plenty of IR coming from the panel already.

If you want quality, overload your plant with damaging blue radiation to trigger mad trichome production and higher levels of THC. UVB isn't even necessary.
