Tsi Fly is known as “Psi Fly” in Europe. Blue Tsi Fly is the result of combining a Chimera C4 female with a Cinderella 99 male, and then backcrossing one generation to an Old Time Moonshine male. This genetic combination gives rise to a bushy plant that is very branchy. Very high yields of tight elongated buds that form HUGE colas. Blue Tsi Fly stretches 50% in flowering so it is best to “open” the plant up to allow light to the interior of the plant. The average plant height ends at 2.5-3.5 feet. Blue Tsi Fly is very easy to grow and clone and produces buds with apricot flavors. Blue Tsi Fly’s best characteristics come through when used in concentrates.

From “Tsi Fly is an evenly balanced hybrid strain (50% indica/50% sativa) created through crossing the powerful C4 X C99 strains. Best known for its super calming and lifted high, Tsi Fly is a great choice for any patient who really wants to kick back and relax after a long and stressful day. The high starts with a subtle boost of effects, creeping into the body and mind with a lifted sense of calming happiness. You’ll feel an influx of creativity come next, filling your mind with a lightly active and stimulating artistic motivation. This will help keep you awake and moving without causing any change in energy levels. These full-bodied effects make Tsi Fly a great choice for treating those patients suffering from conditions such as chronic stress or anxiety, headaches or migraines, and chronic pain. This bud has a sweet and sugary fruity apricot flavor with light hints of woods and pine. The aroma is very similar, with a sweet apricot overtone accented by fresh fruity woods and touches of earth. Tsi Fly buds have rounded fluffy forest green nugs with minty undertones, thin amber hairs, and a coating of tiny milky amber crystal trichomes.”
