Grapefruit Superstar is a predominantly sativa strain bred by crossing Cinderella 99 with a strain known only as Superfast Sativa. Grapefruit Superstar is easy to grow, is fast-flowering and thrives in conditions of low light making it a great choice for outdoor cultivation in higher latitudes.

Vigorous in vegetative growth, Grapefruit Superstar can grow to a height of up to 300 cm. outdoors so it should be put into an early flowering schedule indoors unless space is no problem. Yields of about 500 gr/m² in 8 - 9 weeks of flowering indoors while outdoors in the northern hemisphere harvest will be in late September.

It is a typically-uplifting sativa strain which helps to combat fatigue.
