Seb's take

Seb Silverback

Carat 24 crossed with Green Crack for a lightning-fast autoflower that does not hang about in production or in effect. The high is well-rounded enough for any hour of the day, strong without tipping into excess at 19% THC. Efficient, in every sense.

Growing Sour Crack 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.

She stays under the metre mark — tent-friendly, discreet, and unbothered by low ceilings. Run the numbers on the light planner and she'll fit wherever you put her.

Breeder figures put THC around 19% — firmly in the strong band. The number speaks for itself; we'll not add adjectives to it.
