Northern Lights is an almost pure indica strain and this version from Sensi Seeds has been selectively bred by crossing NL-1, NL-2 and NL-5 which were the only three pure Northern Lights strains hitherto in existence. 

Sensi Skunk is quite possibly the best value seed strain that Sensi Seeds has made commercially available. 

Shiva Skunk is the Skunk strain with the highest level of potency.
