Growing Critical 47
Growing Critical 47 fits temperate and southern Canadian zones — coastal BC, Southern Ontario, and the Niagara region with mild September weather. Critical 47 is photoperiod, which means you control when it flowers by switching from 18/6 (vegetative) to 12/12 (flowering). Most indoor growers veg for 4-6 weeks before the flip. Indoor yields land around 450-550 g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 500-700 g/plant. Expected plant height is 120-180 cm, with intermediate cultivation difficulty. Practical tips that move the needle: flush nutrients in the final 10-14 days for cleaner flavor; trichomes finish properly even on plain pH-adjusted water; and top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola. The most common challenge growers report is over-feeding nitrogen past week 1 of flower — switch to bloom nutrients within 7 days of seeing pistils.

The parental genetics explain the balanced hybrid vigor and adaptability across grow setups you see in the finished plant. Royal King Genetics works from a selected mother line, so seeds run true to type rather than producing the wide phenotype variation cheaper sources are known for.
