Hercules was developed by Dutch breeders Sannie and Knutsel from a cross of Herijuana Shack. They claimed that the outcome is a potent, long-lasting hybrid with a strong coffee flavor and a touch of haze. The breeders claim that this strain has a propensity for sedative effects.
Its large, dense growth can be attributed to its primarily indica lineage, according to Sannie. The flowering period of the plant, which is 9 to 10 weeks long, is best achieved indoors.
