Blue Fire — Humboldt Seeds Organization

Seb's take

Seb Silverback

Blue Fire combines Blue Dream with Fire OG bx1 into the fruitiest strain in Humboldt's catalogue, trichome-covered and built for extraction as much as smoking. The indica lean shows in a relaxed, resinous character, with frosty colas suited to shatter, wax, or hash alike. A beast of a resin producer, and no exaggeration.

Growing Blue Fire: what to expect

Feminized, so you'll not be sexing plants or evicting males. Photoperiod, so veg lasts exactly as long as you decide — see the vegetative stage on how long that ought to be.

Allow 10 weeks of flower, possibly more. Long-flowering lines reward the grower who doesn't count the days aloud — knowing the harvest signs matters more than the calendar here.

Tall, at 400 cm or better. Indoors that means training from early on; outdoors it means picking a spot the neighbours can't see over.

She produces respectably: 500 – 650 g/m² or thereabouts when treated well. Consistency is her selling point — feed her properly and she keeps her end of the bargain.

THC tests around 24%, which is strong by any sensible chart. Respect it accordingly.
