Purple Lemonade FF Cannabis Seeds by FastBuds
Purple Lemonade FF is a photoperiod feminized cannabis seed from FastBuds that delivers autoflower-level speed with photoperiod-level yields. Bred from Tangie and Purple Lemonade Auto genetics, she flowers in just 7–8 weeks and can push out up to 550g/m² indoors. If you want purple-hued buds dripping with citrus flavour and you don't want to wait around for them, this is the one.
Why Purple Lemonade FF Seeds Deserve a Spot in Your Grow
We've seen plenty of FastBuds genetics come through over the years, and the FF (Fast Flowering) line is genuinely impressive. Purple Lemonade FF takes the best traits of their autoflower programme — speed, resilience, compact flowering windows — and drops them into a photoperiod chassis. That means you control the veg time, you control the size, and you still get a harvest window that would make most photoperiod strains blush.
The genetics here are a cross of Tangie and Purple Lemonade Auto, which explains the citrus-forward terpene profile. Crack open a cured bud and you'll get hit with something like freshly squeezed lemonade — sweet, tart, and unmistakably citrus. There's a reason growers keep coming back to this one: the flavour genuinely lives up to the name. It's not a subtle hint of lemon buried under earthy undertones. It's front and centre, like biting into a lemon sherbet.
With THC levels reaching up to 25%, a couple of draws is enough to settle into a deeply relaxing body state paired with an upbeat mental clarity. Traditionally described by growers as soothing without being couch-locking — the kind of smoke you can enjoy in the afternoon without writing off the evening. That said, if you're newer to higher-THC strains, pace yourself. 25% is not a gentle introduction.
Purple Lemonade FF Growing Specs and Yield Data
Here's what you're working with. Purple Lemonade FF can stretch to around 2 metres outdoors, so she needs vertical space or some deliberate training to keep her manageable. Indoors, LST (low-stress training) and topping will keep the canopy even and the height in check. She responds well to both — this isn't a finicky strain that punishes you for bending a branch.
| Specification | Detail |
|---|---|
| Seed Bank | FastBuds |
| Seed Type | Photoperiod Feminized (FF) |
| Genetics | Tangie x Purple Lemonade Auto |
| Flowering Time | 7–8 weeks |
| Indoor Yield | 450–550g/m² |
| Outdoor Yield | 350–550g/plant |
| THC Content | Up to 25% |
| Height | Up to 2m |
| Bud Appearance | Purple hue with dense trichome coverage |
| Seeds per Pack | 3 |
Those yield numbers — 450–550g/m² indoors and 350–550g/plant outdoors — put her comfortably in the heavy-hitter category. For a strain that finishes flowering in under 8 weeks, that's a seriously good return. Most photoperiod strains asking for 9–10 weeks don't produce more than this.
How to Grow Purple Lemonade FF Seeds
She's cooperative. That's the short version. The longer version involves a few practical steps that'll help you get the most out of her genetics.
- Germinate your seeds using the paper towel method or directly in a starter plug. Purple Lemonade FF has solid germination rates — keep the environment warm (around 22–25°C) and moist but not soaking.
- Transplant into your final pot once the taproot is established. A 15–20 litre pot works well indoors. Outdoors, go bigger — 30 litres or directly into the ground if your soil is decent.
- Veg under 18/6 light for 3–5 weeks depending on how large you want her. Remember, she can hit 2m, so if vertical space is limited, flip to 12/12 earlier rather than later.
- Top or FIM during veg to encourage lateral branching. She takes to training well. LST with plant ties will open up the canopy and expose more bud sites to direct light.
- Switch to 12/12 to trigger flowering. She'll stretch during the first two weeks of bloom — account for roughly a 50% height increase after the flip.
- During weeks 3–6 of flower, she'll pack on weight quickly. This is when nutrient demand peaks. A bloom-specific feed with higher phosphorus and potassium will serve her well. One grower in the FastBuds community reported good results using the full Biobizz line with increasing dosage, top-dressing with a charge mix in the first week of flower, then switching to a bloom booster from week 4 onwards.
- Harvest at 7–8 weeks of flower. Watch the trichomes — milky with around 10–20% amber is the sweet spot for that balanced, relaxing-but-not-sedating effect.
- Dry in a dark room at 18–20°C with 55–60% humidity for 10–14 days, then cure in glass jars for at least two weeks. The citrus terpenes really come alive after a proper cure.
Purple Lemonade FF Flavour and Terpene Profile
This is where she really earns her name. The dominant terpene profile leans heavily into limonene — the same compound responsible for the sharp citrus scent in lemon peel. According to a review published in Forests (PMC7559006), D-limonene has been the subject of various preclinical studies examining its biological properties, making it one of the more researched monoterpenes in the cannabis and botanical space.
In practice, what you get from Purple Lemonade FF is a sweet, tangy, almost fizzy lemon flavour on the inhale, with a smoother, slightly candy-like sweetness on the exhale. It's refreshing in a way that most strains simply aren't. If you've smoked Tangie before, you'll recognise the citrus backbone — but Purple Lemonade FF adds a sweeter, more rounded dimension that makes it feel less sharp and more like an actual glass of lemonade.
The buds themselves are genuinely striking. Deep purple colouring develops during the later weeks of flower, especially if nighttime temperatures drop a few degrees. By harvest, you'll have jars full of dense, purple-tinged nugs coated in frosty trichomes. Proper eye-candy.
Honest Limitations — What to Watch Out For
No strain is without its quirks, and Purple Lemonade FF has a couple worth mentioning. First: the height. At up to 2 metres, she's not a strain you can tuck into a 60x60 tent without serious training. If you're working with limited vertical space (anything under 1.8m after accounting for lights and pots), you'll need to top early and train aggressively. She responds well to it, but it's extra work you should plan for.
Second: at 25% THC, this isn't a casual smoke for people with lower tolerance. It's potent. The effect is described as relaxing without being couch-locking, but "relaxing" at 25% THC is still a significant experience. If you're growing for someone who prefers milder strains, this might be more than they're after.
Compared to FastBuds' Gorilla Cookies FF or Tropicana Cookies FF, Purple Lemonade FF trades some raw potency headroom for a more refined flavour profile and that unmistakable purple bag appeal. If flavour and appearance matter as much as strength, she's the better pick.
Growing Purple Lemonade FF indoors? Pair her with a proper grow tent — the Dark Box 80x80 gives her room to stretch without taking over the spare bedroom. You'll also want a carbon filter sorted early; those citrus terpenes are loud, and your neighbours will notice. For outdoor growers, a quality pair of pruning shears and some plant ties will make training sessions quicker and cleaner.
Purple Lemonade FF Compared to Similar Strains
If you're weighing up your options in the FastBuds FF range, here's how Purple Lemonade stacks up against two popular alternatives.
| Feature | Purple Lemonade FF | Gorilla Cookies FF | Tropicana Cookies FF |
|---|---|---|---|
| Flowering Time | 7–8 weeks | 8–9 weeks | 8–9 weeks |
| Indoor Yield | 450–550g/m² | 500–600g/m² | 450–550g/m² |
| THC | Up to 25% | Up to 28% | Up to 25% |
| Dominant Flavour | Sweet citrus lemonade | Earthy cookies | Tropical citrus |
| Height | Up to 2m | Up to 1.5m | Up to 1.5m |
| Bag Appeal | Deep purple buds | Dense, frosty green | Orange/purple hues |
Purple Lemonade FF wins on speed and visual appeal. Gorilla Cookies FF edges ahead on raw yield and THC ceiling. Tropicana Cookies FF sits in a similar bracket but without the dramatic purple colouring. We'd pick Purple Lemonade FF if flavour and looks are your priority — she's the most photogenic of the three, and that lemonade terp profile is hard to beat.
Frequently Asked Questions
Is Purple Lemonade FF an autoflower or photoperiod?
Photoperiod feminized. The "FF" stands for Fast Flowering — she uses autoflower genetics to shorten the bloom period to 7–8 weeks, but you still control veg time with your light schedule. Flip to 12/12 when you're ready to flower.
How tall does Purple Lemonade FF grow indoors?
Up to 2 metres if left untrained. Most indoor growers top her once or twice during veg and use LST to keep the canopy around 1–1.2m. She responds well to training, so height management isn't difficult — just plan for it early.
What yields can I expect from Purple Lemonade FF?
Indoors, 450–550g/m² is the realistic range with proper lighting and nutrition. Outdoors, 350–550g per plant depending on climate and growing conditions. For a 7–8 week flowering strain, those numbers are genuinely impressive.
Why are the buds purple?
The purple colouring comes from anthocyanins in the genetics, inherited from the Purple Lemonade Auto parent. Cooler nighttime temperatures during late flower (around 15–18°C) will intensify the purple hues, but she'll show colour even in warmer conditions.
What does Purple Lemonade FF taste like?
Sweet, tangy citrus — like freshly squeezed lemonade with a candy-like finish. The Tangie genetics bring a sharp lemon backbone, while the Purple Lemonade Auto side smooths it out into something sweeter and more rounded. The flavour is strongest after a 2–3 week cure in glass jars.
How many seeds come in a pack?
Each pack contains 3 feminized seeds. All seeds are photoperiod feminized, so every plant will be female — no need to sex them or worry about males pollinating your crop.
Is Purple Lemonade FF good for beginner growers?
Yes, with one caveat: her height. She's resilient, forgiving of minor feeding mistakes, and responds well to basic training techniques. But if you're growing in a small tent, you'll need to learn topping or LST to keep her manageable. Start with a taller tent or plan your veg period carefully.
