I just place a LED that runs near the 380nm UV, in every 15th slot of my array's. if yer craving wieght think about a couple infrared {about 780nm} tossed into your ratios.
as for light wavelengths outside of the plants asorbtion thats up too you and I hope its not for beta cartenoids cuz those are just piss poor converters of light energy.

One Led light bank running high power LEDs 3w with lensing, specifically a focusing one like 60' or 90' can easily roll on a light rail of 12ft and grow spectacular marijuana. your footprint is very narrow but the light penatration, asorbtion, and cost effiency justifies the cost of the rail. Not to mention if you look at the cost of LED at retail many are priced in line with having to acquire a HPS set up ( hood, ballast, venting, Fan, bulb) Spent 2500 on my LED's for Bud and Veg room and it was worth ten times more. Take a look at them find a US distributor or retailer. enjoy a 3yr manufactuer warranty that they uphold.
