Speed Devil #2 Auto — Sweet Seeds

Seb's take

Seb Silverback

A third-generation refinement of Speed Devil Auto, built bigger without losing the speed that made the original notable - eight weeks from germination to harvest. Indica-dominant, resinous, and heavy-yielding, she keeps everything the family is known for and adds size on top.

Growing Speed Devil #2 Auto: what to expect

She's an auto — on her own clock from the day she sprouts. No switching lights, no waiting on seasons, and no pausing while you sort problems either; read how autos differ before day one.

She takes a conventional 8 weeks to flower. Conventional is underrated; so is knowing what week you're in.

Short and orderly — around 80 cm at full stretch. Small-space growers, this is your candidate; the setup guide covers making the most of a modest footprint.

Expect 400 – 500 g/m² — a working grower's yield, reliable rather than theatrical. The harvest guide will see it in safely.

Listed at 18% THC — potent, verifiably. The figure comes from the breeder's testing, not from our enthusiasm.
