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. 

Watermelon Zkittlez by Barneys Farm: This wonderfully balanced hybrid exhibits heavy sativa growth patterns that help to make her a heavy yielding production factory, with some growers able to achieve more than 1kg per plant when treated with love! Indoors you are going to be looking at around 800g/m2.
