Just how important is 700+ nm?

Hey all. Just how important is this spectrum in my led panel's performance? It is not represented in my current panels, so if I do indeed need it present, how can it be supplemented?

Incandscent light, over a portion of the garden will allow you to see the difference?

Unfortunately a lot of heat as well.. my most original reason for using the LEDs. I guess I'm wondering if there is any reason to implement..
Is this a necessary spectrum?
Should all led panels contain this spectrum for the Emerson effect?

Btw.. Thanks mcfly.. I may pop one in to give that a try in a localized area.. I did not mean to sound unappreciative of your input.. This was not at all the case.

Inda-gro has been studying this aspect especially because that is essentially what their Pontoon is, 730 enhancement. But they have been putting the spectrum science behind it.

End of day far red seems to have more of an effect on flowering? Maybe have the led panel turn off after 11.5hrs and a separate timer provide the last 30mins of incandescent? But I'm a cheap bastard and a few watts of heat shouldn't cause a problem. GL

The pontoon is 660nm in the morning and 730 at lights out, my mistake.

You can actually run your lights longer with 730nm on, even for 5 min intervals. Then plants are coalesced more or less into thinking its time to start shutting down as the sun setting produces 730, so there is light aftwards.

Incandescent is fine, they are cheap too and pretty much the most modular, but you may need more or less depending on the size of your grow. Even a halogen spotlight has its' limits.

I am a believer in UV during the mid-day period as well to supplement high noon max UV.

Supplementing can improve on low wattage yields and destroy when properly integrated with bigger ones.
