Best K (Kelvin) light value for positive (landrace) sativa effects?

[RenaissanceBrah]

I've heard that for growing equatorial landrace sativas indoors, people have recommended high Kelvin lights (10,000K, 6500K, etc) to bring out the most positive effects / high in the genetics.

I'm chasing the most positive effect possible, I don't mind low potency and low yield.

Anyone have experience with varying Kelvin values, and how it changed the effect of the sativa?

(Was going to buy LED lights soon, I saw 6500K Kingbrite lights I was thinking of getting. I would get the whole spectrum of lights, but on a budget, was going to buy two 250W 6500K Kingbrites).

Alibaba shows the 250W Kingbrite lights at 3000K, 3500K and 4000K. Where did you see the 250 watter with the colour temp of 6500K ?

I messaged them, they said it's not an option in Alibaba, but they can send you 5000K and 6500K lights. Might even be able to do higher, I'll ask them.
