About

It's getting harder to rate the frostiness of these new projects, but Sour Stomper is definitely very high up there and can only be described by a potentially invented word 'frostiliscious'.

It's getting harder to rate the frostiness of these new projects, but Sour Stomper is definitely very high up there and can only be described by a potentially invented word 'frostiliscious'. Sour Stomper has actually been the hardest strain to photograph and showcase as its covering of whiteness against its purple hues is difficult to capture and definitely best seen first-hand.

She starts off growing squat and looking very indica, however, when she begins flowering she can really stretch - quadrupling in height throwing out branches and her OG heritage sure makes itself known. From early to mid-flower a sweet red grape smell is evident, this develops throughout flowering becoming more intense and complex with a more raw meatier edge coming through as the flowers build.

The flower-to-plant ratio is extremely high, meaning although the outright size of the plants isn't large, this is a small-medium sized variety, and the yield is impressive. There isn't a big swing in the phenotypes Sour Stomper puts out; we found two-thirds will display colouration under cooler temps, but the flower structures and aromas are very similar throughout.

She is a delight to trim and manicure and is an ideal candidate for extraction work. Performs very well in an autoflower sea-of-green configuration. We pollinated just two candidates to make Sour Stomper F4s, one we've labelled simply as 'the delicious pheno' the other is branded 'whiter than white'.
