Purple Lemonade Auto RF3

Purple Lemonade Auto RF3 is FastBuds’ refined RF3 version of its well-known Purple Lemonade Auto, available as feminised autoflowering seeds. The work here has been aimed at making the line more consistent: stronger purple expression, better plant uniformity, sharper citrus terpenes and a sturdier overall structure.

FastBuds describes this RF3 release as the product of years of continuous selection from the original Purple Lemonade Auto. Large populations were used across multiple breeding cycles, with plants chosen for colour, terpene intensity, vigour and performance. That matters because the purple trait is not being treated as a lucky find. The line has been worked towards reliable deep purple hues across the population, while keeping the sweet lemon candy profile that made the original popular.

The genetics are listed as Purple Lemonade Auto RF3, with a balance of 60% sativa and 40% indica. THC is given at up to 30%, with CBD below 1%. It is still an automatic variety, so flowering is kept simple and quick, with a stated cycle of 9–10 weeks.

Plants are sized as XL and typically reach 80–130 cm. The RF3 work is said to bring improved vigour, denser resin production, stronger structure and better uniformity from plant to plant. That makes it a good fit for indoor, outdoor, greenhouse or mixed-light setups, with the intended climate range covering very hot through to very cold conditions.

Yields are solid for an auto with this much colour in the brief. Indoor harvests are listed at 450–550 g/m², while outdoor plants can produce 50–300 g per plant. The main practical appeal is consistency: purple plants, dense flowers and a more reliable shape than earlier, less-refined expressions.

The flavour and aroma sit firmly in the lemon-sour-sweet corner. Expect sharp lemonade terpenes rather than a flat generic citrus note, backed by sweeter depth and a lemon candy edge. Smell intensity is rated as strong, with dense resin production adding to its appeal for growers who like colourful, aromatic autos.

Purple Lemonade Auto RF3 suits shoppers who liked the idea of the original Purple Lemonade Auto but want a more locked-in version: purple colour across the line, sweet sour citrus, high THC potential and a 9–10 week autoflower finish.
