How to grow Grapefruit Diesel
THC 24% 
Flowering 9 weeks Taste
Seb's take
Grapefruit Diesel carries the classic NYC Diesel nose — pungent, sweet and citrus-forward — with grapefruit undertones added for good measure. The high is relaxed and euphoric, yet leaves room for focus and conversation at 24% THC, delivered on dense buds after a nine-week flower.
Where it comes from
Pheno Finder Seeds are behind this one, though the record leaves the parentage blank — so I will not assign it any. What it does tell us is the reference point: the classic NYC Diesel flavour and smell, with grapefruit undertones layered over. That places it squarely in the sour-diesel tradition, whatever the exact cross, and Pheno Finder have selected it for dense buds and a nine-week finish.
Nose & flavour
Pungent and diesel-forward, the NYC Diesel character the record leans on, cut through with bright grapefruit and citrus and sweetened at the edges. A sharp, mouth-watering nose that does not travel discreetly — the fuel and the fruit playing off one another well.
The high
Relaxed and euphoric, yet with room left for focus, creativity and conversation — a high that mellows without dulling. At 24% THC it has genuine weight behind that clarity. The sort of balance that suits company or a task equally, so long as the task is not too demanding.
Growing it
Feminised, flowering in around nine weeks — roughly 63 days. The record gives neither height nor yield, so I will offer no numbers on either; what it does promise is very dense buds. A grower drawn to the NYC Diesel lineage and that grapefruit twist has the genetics for it, with the finish falling on a standard timeline.
