The specs in one line: 21-26% THC, <1% CBD, 6-7 weeks flowering, 450-550 g/m² reported. Best indoor or outdoor. easy grow.

Smell-first: crack a jar of CheMACal Romance and you get straight diesel with a damp-earth base — no fruit, no candy, just the kind of sharp, fuel-heavy aroma that signals a serious Chem-line cross. That lineage (Chemdawg × MAC Auto) backs up what your nose is telling you: THC tests consistently land in the 21–26% range, which is on the higher end for an auto. Despite those numbers, the plant itself is forgiving — growers running it indoors or out report it doesn't demand much attention, and the 6-to-7-week flower window means you're pulling harvests faster than most photoperiod runs. Dialed-in indoor setups can hit 450–550 g/m², which is respectable output for an autoflower without pushing advanced nutrients or complicated light schedules.

Good fit for experienced growers who want Chem-cut potency on an auto timeline, or newer growers ready to step up from milder strains.
