I usually try to stay from any 'lemon' strain, but this one is just wonderful. Melts away your stress, lifts up your mood, can watch something on tv without couchlock, and it does wonders for managing migraines. I've been getting Botox injections for over a year to help treat migraines, so I don't throw that around lightly. Picked up a quarter ounce flower by Anthologie at Heath for Life in QC, Arizona.
I've gotten Green Crack from two different dispensaries now, and they've both been consistently great. A nice mood booster when you need it, and energizing too. As with some Sativas, just don't overdo it, or you may bring on sleepiness and anxiety. It doesn't do anything for migraines, but may banish a minor headache.
If you ever get the chance to get some, especially from Health for Life in Arizona (H4L flower) or from TruBliss (Nectar flower), I recommend snagging some.
IMO, the one from Sticky Saguaro (Huxton flower) is dry and doesn't have the same quality effects.
