Growing Red Rum: what to expect

As a hybrid, expect a moderate stretch after the flip (around 100%) — but watch the plant, not the label: phenotypes within Red Rum can lean either direction. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.

Red Rum FAQ

Is Red Rum an indica or a sativa?

The breeder doesn't specify — treat it as a hybrid and read the plant.

What environment does Red Rum like?

Standard cannabis bands work well: VPD 0.8–1.1 kPa in veg and 1.0–1.4 kPa in flower, with humidity stepping down from 65–75% as a seedling to 40–50% in late flower. See the stage-by-stage table on this page.
