Effect: One of the highest measured THC. Devastating, Fast Cerebral. Flowering indoor: 9 weeks for full production and resinFlowering outdoor: Ready in between mid and end October (Europe)THC: 21.49% - CBD: 1.05% - CBG: 1.78%The Alaskan Ice is one of the strongest cannabis plants ever bred. It is a cross of original Green House White Widow and Pure Haze. This variation represents a very famous strain, with a new kick. The plants have a structure that is slightly stretchier than the White Widow, with a typical pine-tree shape. The internode is quite stable and averages 12-15 centimeters. The strain has all the well known characteristics of the White Widow, with a much higher THC content and a very sativa-like effect, energizing and very trippy. CBD level is also very high at over 1%, giving it a complete physical effect that follows the first burst of high. Flowering time on this strain is 9 weeks, just one week longer than the original White Widow. The Alaskan Ice is suitable for indoor, outdoor and greenhouse. The plant is quite resistant to botrytis and to pests. In indoor hydro systems the production can reach 700-800 grams per square meter. Outdoor expect production up to 800 grams per plant with fully developed specimens (up to 2,5 meters high and very branchy). The Alaskan Ice can be fed quite a bit, with an EC level up to 2.2 in hydro systems (regular flush required). The taste of the Alaskan Ice is spicy and hazy, with a very well balanced bouquet in between the White Widow and the Haze flavors.
