Jack Flash is an Indica-dominant hybrid that won the Dutch High Life Cup in 1998. Although Indica-dominant, it is loved for its strong Sativa-based cerebral effects.
Starting strong, the strain induces psychedelic and euphoric state, elevating one's mood. After the initial high fades (roughly 30 minutes after use), the strain often increases the desire to socialize or to be creative. This effect is followed, an hour or so after use, by a body buzz that settles in slowly, often causing users to feel lethargic and sedated. Some also report that at this time the strain acts as an aphrodisiac.
Jack Flash's pleasant effects can last over two hours even when it's consumed in small doses. However, users may also experience dry mouth and eyes, dizziness, and even paranoia with higher doses.
Due to the euphoric effects of this strain, it is often recommended for those suffering from stress, anxiety, and depression. Jack Flash's body buzz will not relieve all aches and pains but may ease lesser ones. Many also find it useful for calming nausea and inducing appetite.
Jack Flash was designed by Sensi Seeds to have the most desirable qualities of Jack Herer and to be an easy strain to grow even for a novice. It is a cross between a Jack Herer mother and a mix of Super Skunk and Haze father. The strain was made for indoor grow operations. It grows well in the Sea of Green technique and flowers around nine to ten weeks. Moderately experienced growers can produce a slightly above average yield.
