How to grow Nepal Jam
THC 14% 
Flowering 56 - 63 days Taste
Seb's take
Nepalese stock crossed back through a touch of Jamaican '85 for colour and vigour, while keeping its sativa behaviour intact. Sweet, honeyed and caramelised on the nose; the high runs warm, clean and expansive, uplifting and relaxed in equal measure. Bred to shrug off cold and rain that would trouble most others.
Where it comes from
Nepalese stock crossed through a touch of Jamaican '85, then folded back onto Nepalese again — a line that keeps returning to its mountains. The Jamaican addition brings vigour, a little extra yield and the bluish colouring, along with that clean, classic effect; the Nepalese half holds the sativa behaviour steady throughout. Ace Seeds bred her, in short, to travel to colder ground than most of her relatives would tolerate. A hardy expatriate that never quite forgot where she came from.
Nose & flavour
Seductively sweet, the record says, and it is not overstating things. Honey leads, caramelised and warm, with a creamy softness rounding the edges. There is nothing sharp or fuel-driven here; the whole nose sits in the comforting register, sweet without cloying. A pleasant, unhurried aroma that suits the temperament of the plant behind it.
The high
Warm, clean and expansive — uplifting to begin with, easing into a relaxed, happy contentment. At 14% THC she is honest about what she is: a gentle, sociable sort rather than a heavyweight, the kind of company that lifts an afternoon without commandeering it. A sativa lean keeps the head clear and the mood open throughout.
Growing it
The record withholds firm figures for height and yield, so temperament will have to do — and here the temperament is the whole selling point. She is bred to shrug off cold, rain and fungus that would flatten most others, holding her own through fog and icy days from warm climates to the north of Central and Eastern Europe. Structure runs small to medium and columnar, with flowering across 56 to 63 days. A grower's insurance policy against a bad summer.
