The ICE medical marijuana strain is a selected phenotype out of a Skunk Special x White Widow cross, back in 1996.
Popular with Dutch growers in the 1990's, ICE was selected out of 500 females, because she the had best of both sides. The enormous buds of the Skunk Special, the trichome coverage and power of the White Widow, with an Indica look.
During the High Times Cannabis Cup of 1998, the highest THC levels were measured in the ICE (published in Weed World).
Years of backcrossing and cubing have been spent to stabilize this cross towards the first phenotype. Even a little bit of Blueberry was crossed in and stabilized again.
She smells like diesel fuel and the flowering period is 8 weeks. Although an indoor strain, ICE grows perfectly outdoor in tropical climates.
