This strain emerged from the Bay Area of California and that area’s telephone area code is the source of its numerical moniker. It’s a cross between Sour Diesel, OG Kush, and Master Kush. 707 Headband plants flower in 9 to 11 weeks and usually have large yields. An indica dominant hybrid, this strain is known to have high THC levels and can be strong, but it’s balanced enough to leave most users feeling “heady” and creative rather than sleepy. Because of this, it’s often used to treat tension and anxiety.
