How to grow Runtz XL Auto
Seb's take
Crossed with Sweet Gelato Auto, years in the making to get a proper autoflowering Runtz rather than an approximation. Sweet and fruity on the nose, true to the family; the high runs relaxed, happy and creative rather than flattening. At 17-25% THC, a fair spread depending on the phenotype you draw.
Growing Runtz XL Auto: what to expect
An autoflower: she flowers on age, not on light hours, which removes the single biggest way to get the schedule wrong. The auto versus photoperiod lesson explains what that changes — which is nearly everything.
Flowering runs the standard 8 weeks — no surprises, which in this business is a compliment. The flowering stage guide covers what each of those weeks should look like.
A middling 120 cm or so at maturity — tall enough to yield, short enough to manage. Standard tent territory; the light planner sorts the hanging height.
A solid, dependable yield — 400 – 550 g/m² under decent conditions. Nothing that requires bragging; everything that justifies the effort. The yield lesson covers getting to "decent conditions".
THC of 25% by the breeder's numbers — the top shelf of the scale. Approach as you would a staircase in the dark.
The nose runs sweet — dessert-adjacent, without apology.
