Seb's take
Northern Lights, Diesel and Super Skunk stacked together with a touch of Ruderalis for a sativa-dominant autoflower that announces itself well before you find the plant. The head high is dreamy and fast-acting, happy and energetic rather than heavy. A proper wake-and-bake, at 22-25% THC.
Where it comes from
Four strands here - Northern Lights, Diesel and Super Skunk over a Ruderalis base - Herbies Seeds building the sativa Sour Diesel into an automatic without losing its character. Northern Lights steadies it, Diesel names it, Super Skunk thickens it, and the Ruderalis sets the clock. Sativa-dominant despite the automatic frame, and the pungent reputation of the line survives the conversion intact.
Nose & flavour
Sharp and tangy, sour and diesel-forward over an earthy base - the record reckons you will smell it from miles away, and there is no reason to doubt it. The classic fuel signature, carried whole into an autoflower. This one does not travel discreetly, so factor the aroma into where you grow it. Loud, oily, and unmistakable.
The high
A classic sativa head high - dreamy, fast-acting, happy and energetic, with a creative streak running through - at a properly strong twenty-two to twenty-five per cent THC. The record files it as a wake-and-bake, the sort that starts the day rather than ends it. Quick to arrive and cerebral in direction; morning company rather than evening.
Growing it
A slower automatic - eighty-two to eighty-seven days from germination - so this is not the one for the impatient, for all its fast-acting effect. Height stays workable at 70 to 120cm, with yields of 300 to 450 g/m². The pungency argues for a filter and some thought about placement. Give her the long window she needs and the strength on paper arrives as promised. Patience up front, reward at harvest.
