Add IR to what you have? An incandescent lamp perhaps. Or a 730nm array. The cheap lamp would be a good start, to assess if it's what you need to get over this edge.
How would you like to do it. If you have bar lights, do you want to add another bar? At 30 units, I dare say I could have a manufacturer populate a board/strip with just 730s for you.
Alternately you are looking at separate units to hang.
Do you have any old halogen lights?
Look at the 730 peak and the 840. This lamp is perfect for some spectrum fill-in. Terrible lights, but good heaters.
Usually the peak is a bit higher. The pics from here: https://warisanlighting.com/halogen-lamp-spectrum.html
Using LEDs for 730, gives you just 730. A narrow peak on a graph like that. A peak that's not even a tenth of the spectrum width covered by a while light, trying to put it's 650w? across 450-650 perhaps. So, to get as high a 730 output, as say the 600 output of your whites... might take less than 65w. It might be 40w. Or 20w. Lights with 730nm added, don't add 10% more.
I bet there is some rule of thumb to this. If you are trying to replicate some particular brand, you might need to get counting.
I used a 60w halogen lamp with 550w of decent white. There was an effect of plant morphology, but I saw no gain elsewhere. I just use the stretch when I need to. It wasn't a conclusive test though, just a few runs. No side by side.
Have you looked at Electric sky?
Fuk Mars.
that is all

Next light will be the ES 180 V3.
I’m in a 2x3x5’ with 2 SF 1000 and killing it but I’ve had them going on 2 yrs so they’ll be needing replacement soon.
I like the interest free pay over time option ES offers.
