How to grow Oblivion Black

30% indica - 70% sativa
Oblivion Black — Hero Seeds

Seb's take

Seb Silverback

Amnesia Haze, Ortega, Afghani SA and Hash Plant sit behind this 70% sativa hybrid — a genetic profile complicated enough to explain both the bulk and the height. The high runs energising and heady, true to that sativa lean. One of Hero Seeds' more resilient and powerful offerings, by their own account.

Growing Oblivion Black: 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.

Breeder figures put THC around 22% — firmly in the strong band. The number speaks for itself; we'll not add adjectives to it.
