Strain description

Photoperiod-dependent, ultra-fast-flowering version of Rainbow Sherbert #11, a famous Californian “Super Strong” strain. To shorten its flowering period and introduce new aromatic nuances while maintaining its potency, we have crossed it with our Papaya Zoap Auto® (SWS107).

As for aromas and flavors, this strain features a symphony of sweet and fruity notes, dominated by mango, papaya, and citrus tones, complemented by subtle earthy, smoky, and spicy hints.

Its effect is highly potent, delivering a joyful and relaxing sensation that opens the mind while inspiring creativity and imagination.
