About this format
Cannabis seeds are sold as collectable souvenirs and for the preservation of genetics. Feminized seeds grow into female plants, autoflowers switch to bloom on their own regardless of light schedule, and regular seeds produce both sexes for breeding. Germination is illegal in many countries — know your local law before you buy.

Purple Lemonade Auto RF3: Californian Genetics, Locked In
Purple Lemonade Auto RF3 is Fast Buds' third-generation stabilised take on one of their most visually striking strains. Built on Californian Purple and Citrus genetics with ruderalis in the cross, the RF3 designation marks the point where years of selective breeding paid off: uniform purple expression, consistent plant structure, and reliable vigour across every seed in the pack. The result is a 60% sativa / 40% indica autoflowering strain with THC reaching up to 30%, putting it firmly in experienced-user territory. The sativa-dominant character sets the experience expectation before you even crack a seed.
Tall for an Auto, Productive for a Tent
Purple Lemonade Auto RF3 runs 80-130cm, which is XL by autoflowering standards. That height range applies indoors and out, so factor it into your space before you start. LST is worth doing here: bending and tying early keeps the canopy manageable and gets light into the lower sites that would otherwise get shaded. No light cycle management needed, one of the core advantages of the autoflowering format. Indoors, yields land between 450-550g/m², which is strong productivity for an auto. Outdoor plants can vary considerably, with harvests ranging from 50-300g per plant depending on conditions. Flowering runs 9-10 weeks, a straightforward timeline for planning your cycle.
Sour Citrus on the Nose, Creative on the Come-Up
The flavour profile is the strain's signature: sharp lemon and sour citrus up front, with a sweet finish that rounds it out. It's a clean, bright sensory experience, not a heavy or dank one. Effects follow the sativa lean: uplifting and creative early, settling into a relaxed, happy finish without going sedative. Good for daytime through early evening use. The deep purple colouration that the RF3 line was bred to lock in makes harvest time genuinely satisfying, dense, resinous buds with that distinctive hue across the whole canopy rather than just the odd pheno. One honest note: the height means this isn't the most discreet auto on the shelf. If ceiling space is tight, plan your training early or consider a more compact variety.
