Black Rose Feminised

Black Rose is bought for what comes off it, and the sourced figures are 450–550 g/m² under lights and 500–700 g/plant from a plant grown out. Those are ceilings, not promises — pot volume, light intensity and how honestly you feed decide where you land inside them. Run the numbers for your own tent with the yield calculator before committing to a pack size, and put it next to the rest of the high-yield strains if weight is the whole point.

What the sourced data gives for this cultivar: 450–550 g/m² under lights, 500–700 g/plant from a plant grown outside. Reaching either is an environment problem before it is a genetics one.

Root volume sets the ceiling before a single flower forms. Under-pot a plant and no feeding schedule rescues it. Get the container right early and the plant does the rest.

Light is the second lever, and the one most growers get wrong in both directions — too little through veg, too much in late flower where it bleaches rather than builds. Steady beats aggressive.

The third is the fortnight around the flip. The stretch after the flip decides your final canopy shape, and it is the last moment training does anything useful.

Feed to the plant rather than the calendar. Our nutrient calculator gives a starting schedule; the plant will tell you where it is wrong. Worth a side-by-side comparison before you commit if weight is the deciding factor.

Reported effects cluster around relaxed, calm. At 22% THC that is a meaningful figure rather than a decorative one, and the sensible approach with anything in this range is to start lower than you think and wait longer than feels necessary.

The 73/27 balance shapes where it lands: body-forward, better suited to an evening than a task list. Tolerance moves this more than any other variable, which is why two people describe the same jar differently.

Prefer something gentler? The CBD-forward strains range trades peak potency for balance.

Caryophyllene leads, myrcene sits behind it, and bisabolol runs underneath.

Temperature changes what you get. Vaporised low, around 180 to 188 degrees, myrcene and bisabolol come through cleanly while caryophyllene stays in the background. Combusted, caryophyllene dominates and the finer detail is largely lost. Same flower, two different experiences.

Who does well with Black Rose? Growers who want to control plant size and harvest date, and have the vegetative space to use that control. First-timers included — the genetics are forgiving.

Still deciding? The indoor-friendly genetics list is the narrower place to start.
