About Grapefruit Auto

This strain is a hybrid cross of Grapefruit and Ruderalis. Its lineage is rooted in Cinderella 99 (Jack Herer × Shiva Skunk) × Thai, though according to Blimburn, it can also be traced back to Gorilla Glue #4 × Zkittlez. It is a parent of Zkittlez, Fruit, Grape Diamonds, Grape God, and Berry. Expect a profile dominated by fresh grapefruit peel, lemon, and orange, often finishing with a sweet, slightly bitter aftertaste and a floral touch.

As an autoflowering variety, it is designed for simplicity and speed, typically completing its flowering cycle in 8 to 10 weeks. The plant structure is compact and well-branched, making it suitable for indoor setups, balcony grows, or outdoor gardens. It is noted for being resilient against pests and diseases, thriving in fertile soil with ample light and air. Yields can reach up to 600 g/m² depending on the environment.

Pick the Fast Buds version for a high-producing autoflower that emphasizes a balanced high with a calming body impact.
Choose the Crop King Seeds version if you are looking for a 100% sativa profile with a focus on creative and talkative effects.
Select the Seeds Mafia version for a high-THC option that reaches up to 120 cm when grown outdoors.

This strain suits growers who want a manageable, fast-growing plant that produces a bright, energetic, and euphoric experience without the complexity of light cycle management.
