SPECIAL GROWING INSTRUCTIONS: Please do not sprout these on a 24/0 photoperiod and KOS recommends 16/8 for sprouting and until 30 days old. Always allow plants to get at least 55 days old from sprouting, before starting to flower for maximum resin production; for Darkling Sativa I would recommend 65-70 days before flowering, and I would flower only clones indoors. KOS always recommends organically growing our gear for the full appreciation of smells and flavors.

Parental Info

MAMA:  The Cinderella 99 is a super long IBL sativa dominant that is also fast (56-58 days) which will counter the longer flowering times of the Black Forrest (16 weeks). She is a serious connoisseurs’ delight with flavors reminiscent of Haze and overripe figs, mucho delicious! The Darkling Sativas will get large, and if topped she will end up like a huge Medusa’s head full of large and long gooey buds. She will stretch quite a bit into flowering (more than doubling her size).

PAPA: The Black Forrest male I used in this cross is my old Vietnam Black landrace jungle sativa crossed to my old f3 Cherry Bomb. This variety is a stupendous killer with legs around 5 hours (length of effects) and I have made this cross before when I was ‘Magick Kingdom’ Seeds and called it “Cindy Black.” So I already know a lot about this cross and what to expect from it. The smells and flavors of the darkling Sativa will be mostly super Hazy/Cat Piss with a background of plumb & honey oil. Cat Piss lovers’ dreamboat right here with a full—basically pure blooded—sativa wallop!
