With roots going back to the 1970s cannabis industry, this powerful sativa is worth a try. A cross between Neville’s Haze and Colombian Red, Red Haze is a grower. Having a flowering time of 12 to 14 weeks, this strain may be difficult to find in dispensaries. If you do find it, however, be prepared for a experience. Supplying a light-headed feeling, the strain’s ramifications are especially long-lasting. Red Haze is a strictly strain, as its effects may be similar to drinking a cup of coffee.
