Adding UVB to an outdoor grow?

[HappySrirachaSauce]

the Indicas I’m growing grew in climates with more concentrated uvb light than where I will growing them. Is There a way to implement UVB lighting in a small outdoor grow so I can get them to throw out more resin? I know how to do this easily in an indoor environment but I haven’t heard of way to do it outside.

Seems like a whole lot of hassle for minimum gain, I have grown outdoors for over 15 years and never wanted to try and augment the sun.
