How to grow Birthday Cake
Seb's take
Durban Poison, Granddaddy Purple, and Girl Scout Cookies combine for an 80:20 Indica hybrid built on dessert flavours — buttery, nutty, sweet, and vanilla throughout. The high runs euphoric, happy, and relaxing, with an appetite close behind, suited to any occasion worth celebrating.
Growing Birthday Cake: 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 9 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 130 cm or so at maturity — tall enough to yield, short enough to manage. Standard tent territory; the light planner sorts the hanging height.
The yield is, in plain terms, heavy — 549 – 641 g/m² when she's looked after. Branches will need support before they need sympathy; see supporting heavy colas.
THC of 27% 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.
