Critical Chronic Auto — Sumo Seeds

Seb's take

Seb Silverback

Critical Chronic crossed with Ruderalis for a compact, skunk-descended autoflower that shrugs off warm, dry climates better than most — a particular favourite across Southern Europe. She stays small, 60–80cm indoors, and is ready in as little as six weeks. Medium potency, straightforward growing, no surprises.

Growing Critical Chronic 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.

She finishes flowering in around 7 weeks — brisk work by any standard. Read up on the flowering stage before she starts, because she won't wait while you do.

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.

The yield is modest — honest about what it is. What she lacks in volume she asks for in fewer demands; the harvest guide applies at any scale.
