Seb's take
Lemon Haze and Jack Herer distilled into a no-fuss autoflower, sativa-dominant and suited to compact grows or a sunny balcony. Sweet, fruity citrus carries the nose, and the high runs relaxed, focused and euphoric without tipping into paranoia — a dependable workhorse rather than a showpiece.
Where it comes from
Seedkeepers distilled Lemon Haze and Jack Herer into a no-work autoflower, folding in their Keepers Ruderalis to set the self-timing clock. It runs 40 percent indica to 60 sativa, mixing legendary West Coast genetics into a compact, quick-bloom package suited to small grows and sunny balconies. The Jack Herer supplies the pedigree and the lift, the Lemon Haze the citrus, and the Ruderalis the convenience. A workhorse cross, built for ease as much as character.
Nose & flavour
Sweet and fruity, with a citrusy lemon running through the whole thing, the record leaning hard on that citrus character. It is a bright, approachable profile, the fruit and the lemon together making for an easy, moreish nose. Nothing overwrought, just a clean, sunny citrus that suits the compact, cheerful plant it comes from. Fresh and forward, and pleasant to have around.
The high
Bright without the edge. The effect runs relaxed, focused and euphoric, functionally cheerful in the record's words, and pointedly without the paranoia that sometimes trails a sativa-leaning plant. It is an energising, mood-lifting high that keeps the head clear and comfortable, a dependable daytime character rather than a heavy one. Cheerful, focused company, and an easy one to spend an afternoon with.
Growing it
A no-fuss auto, perfect for compact grows, sunny balconies and anyone after a quick brightening of the day. She stands around 120cm, a comfortable medium, and flowers over 60 to 65 days from the automatic clock. Yield sits at 350 to 400 g/m², and THC at 18 to 20 percent with CBD under 1 percent. The record calls her a workhorse favourite, and the combination of quick bloom, small footprint and reliable output bears that out. Steady light and conditions, and she mostly runs herself.
