Purple Lemonade Auto by Fast Buds
Purple Lemonade Auto by Fast Buds has been around long enough to become one of the breeder’s signature purple autoflowers, but it hasn’t simply been left untouched.
Fast Buds has continued working on the genetics over the years, with the standard version now listed as:
Original Lemonade Cut × LSD25 Auto F5
The result is an F6 feminized autoflower with up to 25.5% THC, an approximately 9–10 week cycle, and the sweet-and-sour citrus profile that gave Purple Lemonade its name in the first place.
Then there’s the colour.
Deep purple flowers, bright orange pistils and a thick coating of resin make this one fairly difficult to mistake for anything else.
At SeedMasters.com, we think Purple Lemonade Auto is a good example of an autoflower that’s managed to stick around while the market has changed enormously around it.
Original Lemonade Cut × LSD25 Auto F5
Fast Buds now gives the genetic formula much more precisely than it did in some of its older descriptions.
Purple Lemonade Auto combines an Original Lemonade Cut with LSD25 Auto F5, with the resulting genetics subsequently refined into the current F6 autoflower.
That’s worth mentioning.
F6 tells us considerably more about the breeding work behind Purple Lemonade Auto than simply describing it as a cross between purple and citrus Californian genetics.
Fast Buds has continued selecting the line over multiple generations, concentrating on the characteristics that made the original release popular: purple colouring, strong citrus terpenes, resin and consistency.
In other words, this isn’t a newly made F1 wearing a familiar name.
There’s some breeding depth behind it.
Sweet, Sour and Properly Lemony
Fast Buds describes the terpene profile as:
Sweet · Sour · Citrus · Lemon
And the lemonade comparison is pretty accurate.
This isn’t just generic citrus sweetness. There’s a noticeable sour side to the profile, giving it the sharpness of freshly squeezed lemon before the sweeter notes arrive behind it.
Fast Buds calls the resulting flavour bittersweet, and that’s probably the best single word for it.
At SeedMasters.com, that’s what separates Purple Lemonade Auto from strains that simply list “lemon” somewhere among ten other flavours.
Lemon isn’t hiding in the background here.
It’s the whole point.
You get sharp citrus, mouth-puckering sourness and enough sugary sweetness to make the Lemonade name feel justified.
One of Fast Buds’ Signature Purple Strains
Obviously, we need to talk about the purple.
Fast Buds itself calls Purple Lemonade Auto one of the best purple varieties it has created, and visually it’s easy to see why the strain became so closely associated with the breeder.
The flowers can develop deep purple colouring contrasted by vivid orange pistils, with a heavy trichome layer adding an almost frosted finish.
Fast Buds also mentions pinkish tones appearing through the resin in some expressions.
It’s a striking combination.
The current standard version is classified as XL, with Fast Buds giving a height reference of approximately 80–130cm.
Production is listed at around 450–550g/m² indoors, while the breeder gives an outdoor reference range of approximately 50–300g per plant.
The complete autoflower cycle is approximately 9–10 weeks.
For SeedMasters.com customers, these specifications are included as breeder-supplied reference information for comparing and identifying collectible cannabis genetics.
Up to 25.5% THC
Fast Buds currently lists Purple Lemonade Auto at up to 25.5% THC.
Again, we’d keep the wording accurate.
That’s up to 25.5%, rather than an average of 25.5%.
The breeder describes the overall character as having two fairly distinct stages. It starts on the brighter side, with an uplifting character, before gradually becoming calmer and more physically relaxing.
Fast Buds’ own customer feedback data also puts relaxation, happiness and uplift among the most commonly reported characteristics.
As always, THC percentages and characteristics are breeder-supplied reference information rather than guaranteed results for every individual expression.

Our Take on Purple Lemonade Auto
At SeedMasters.com, Purple Lemonade Auto feels a little different from some of the Fast Buds strains we’ve added recently.
It’s already got history.
While newer releases arrive with fresh crosses and enormous THC figures, Purple Lemonade Auto has been part of the Fast Buds catalogue for years. More importantly, the breeder has kept working on it.
The current standard version has reached F6, which is exactly the sort of detail we like seeing.
It tells you that Purple Lemonade Auto isn’t simply surviving because people recognise the name. Fast Buds has continued selecting and refining the genetics behind it.
And the identity of the strain remains incredibly simple.
Purple flowers and lemonade terps.
That’s it.
No need to invent a flavour list stretching halfway down the page.
We also like the contrast between the dark flowers and bright citrus profile. Visually it looks deep, rich and almost heavy, yet the aroma heads straight towards sharp, sweet-and-sour lemon.
There’s now an even newer Purple Lemonade Auto RF3 in the Fast Buds catalogue, but we wouldn’t confuse the two. The RF3 is a separate upgraded release with its own specifications and deserves its own SeedMasters.com product page.
This original F6 version still has plenty going for it.
Original Lemonade Cut × LSD25 Auto F5.
Up to 25.5% THC.
Deep purple flowers.
And enough sweet-and-sour citrus to explain exactly why it’s called Purple Lemonade.
Sometimes a strain name really does get it right.
