Energizing or sleepy?
Mostly energizing. Leafly places Cinderella 99 on the energizing side of its calming-to-energizing scale, and its users most often report feeling energetic, uplifted and focused.1 Not every report is pleasant: anxiety and paranoia are among Leafly users’ most-reported negatives, and the breeder calls the high it inherited from Princess "speedy" and "scary".1,4
Why two batches can feel different
Potency alone varies widely: one in ten lab-tested batches came in under 15.56% THC and one in ten above 26.00%.9 The name also covers several seed lines, from the Brothers Grimm original and its 2016 remake to Female Seeds’ C99, which Female Seeds says comes in grapefruit and pineapple phenotypes (see genetics).4,6,10
