Runtz Gum — Original Sensible Seeds

Seb's take

Seb Silverback

Z crossed with Grapefruit Bubblegum, a pairing that reads like a dessert menu and smokes like one too — sweet, citrus fruit throughout. At 28% THC the high runs relaxed, euphoric and creative in fair measure, true to its 60/40 sativa-indica balance. A well-mannered grow from seed to harvest.

Growing Runtz Gum: what to expect

Feminized photoperiod seed: every plant a female, and flowering starts when you change the lights — which puts the calendar in your hands. The photoperiod lesson covers using that control well.

Flowering runs the standard 10 weeks — no surprises, which in this business is a compliment. The flowering stage guide covers what each of those weeks should look like.

The yield is, in plain terms, heavy — 700 g/m² when she's looked after. Branches will need support before they need sympathy; see supporting heavy colas.

THC of 28% 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.

Reported effects lean relaxed — the sitting-down sort.
