How to grow Cold Thunder
THC 23% 
Yield 600 – 1000 g/m² 
Height 300-350cm Seb's take
Built for guerrilla growing, Early Sativa and Alaskan Thunder combine into a root system strong enough to push through hard ground and a plant tall enough — 300 to 350cm — to make indoor cultivation pointless. The record stops short of nose and effect, but yields of up to a kilo per plant in a sunny outdoor spot speak for themselves. Give her the headroom, quite literally.
Where it comes from
Sumo Seeds built this one for guerrilla growing, crossing Early Sativa with Alaskan Thunder to give a plant with a root system strong enough to push through hard substrates and grow in almost any ground. Eighty-five percent sativa, and described as the breeder's most stable and uniform strain. A purpose-built outdoor plant, in short, bred for resilience first and everything else second.
Nose & flavour
The record does not list the aroma or flavour, and I will not invent one for a plant this plainly bred for the field rather than the tasting notes. Take the Alaskan Thunder parentage as a hint toward something robust, but the detail goes unrecorded, and honestly so.
The high
Unrecorded in the detail, so I will leave it there. The record's interest is squarely in the growing rather than the effect, and I will not put a character on it that the source does not support. An 85% sativa lean is all the inheritance offers, which points toward the brighter end without committing to specifics.
Growing it
This is the whole story. A feminized plant with a very strong root system that reaches 300 to 350cm and is not suitable for indoor growing on account of it, so give her the headroom of an actual sky. In sunny areas she is ready to harvest at the beginning of September, with yields of 600 to 1000g per plant, near enough a kilo at the top end. Described as one of the best outdoor strains on the market, and among the most stable and uniform Sumo offer. Give her the field, quite literally, and she asks little else.
