Lemon Tree Fast (Lemon Tree x Silent Seeds)

Lemon Tree Fast Seeds by Silent Seeds — 24% THC Citrus in Under 8 Weeks

Lemon Tree Fast is a feminized photoperiod hybrid that delivers the full candy-lemon punch of the original Lemon Tree in a dramatically shorter flowering window. Bred by Matthew Rockwell through a cross of Lemon Skunk Auto IX5 and the Original Lemon Tree, this collaboration between Silent Seeds and Lemon Tree genetics shaves roughly two weeks off the usual bloom cycle without sacrificing potency or yield. If you've grown the original and wished it finished sooner, this is the seed you want in your hand right now.

Why Lemon Tree Fast Cannabis Seeds Deserve Your Grow Space

Speed usually costs you something. Smaller buds, weaker terps, a vague sense that you settled. Lemon Tree Fast doesn't play that game. Silent Seeds kept the original's genetics intact — the same Lemon Skunk and Sour Diesel lineage that made Lemon Tree a dispensary staple — and introduced rapid-flowering Skunk genetics to compress the timeline. The result is a plant that finishes its bloom in 55–58 days indoors, compared to the 60–70 days you'd expect from the standard cut.

We've seen growers get impatient with long-flowering sativas and chop early, losing both weight and flavour. That's the real beauty here: Lemon Tree Fast removes the temptation entirely. You get a full, mature harvest before restlessness kicks in. And the numbers back it up — up to 600 g/m² indoors with proper lighting and nutrition, or a staggering 1200 g per plant outdoors where she can stretch to 200–220 cm by late September.

The one honest limitation: this is still a vigorous, stretchy hybrid. Indoor growers in small tents (60x60 or under) will need to top or train early, or she'll outgrow your headroom. An 80x80 tent with a proper SCROG net is the sweet spot for controlling her height while maximising that canopy coverage.

Lemon Tree Fast Terpene Profile and Effects

Open a jar of dried Lemon Tree Fast and the first thing that hits you is sharp, sweet citrus — like cracking open a bag of lemon boiled sweets. Underneath that initial candy brightness, there's a lingering chemical-fuel note inherited from the Sour Diesel side of the family. It's pungent. Your carbon filter earns its keep with this one, especially in the final two weeks of flower.

The dominant terpene here is limonene, the same compound responsible for the scent of lemon peel. According to a review published in PMC, many clinical and animal studies have shown that citrus metabolites — including limonene — may help protect against the effects of reactive oxygen species (PMC, 2023). Separately, research into limonene's neuroprotective potential suggests that plants rich in this terpene could be possible therapeutic agents, though human clinical data remains limited (PMC, 2021).

At 22–24% THC, the effect profile leans toward an initial wave of uplifting, creative energy that gradually settles into soothing physical relaxation. It's a balanced hybrid in the truest sense — the head stays clear while the body unwinds. Compared to something like a pure Sour Diesel cut, the comedown is gentler and less racy. Compared to a heavy indica like Northern Lights, there's far more daytime usability here.

How to Grow Lemon Tree Fast Seeds

Lemon Tree Fast is a forgiving plant with a vigorous growth pattern, but a few smart moves during veg will pay off massively at harvest. Here's how we'd run it.

1. Germination: Soak seeds in a glass of room-temperature water for 12–24 hours, then transfer to damp paper towels in a sealed container. Keep warm (22–25°C). Taproots typically emerge within 48–72 hours.
2. Seedling stage: Transplant into a small pot (0.5–1L) with light, airy soil or coco. Keep humidity around 65–70% and light intensity low — an 18/6 cycle under a modest LED is plenty.
3. Vegetative growth: Once the plant has 4–5 nodes, top it to encourage lateral branching. This is a stretchy hybrid, so training techniques like LST or a SCROG net are your best friends indoors. Expect her to roughly double in height during the flowering stretch.
4. Flip to flower: Switch to 12/12 when the canopy fills about 60–70% of your available space. She'll stretch and fill the rest. Indoor bloom runs 55–58 days — mark your calendar.
5. Late flower and harvest: In the final two weeks, watch trichomes with a jeweller's loupe. Aim for mostly cloudy with a handful of amber for the balanced head-and-body effect this strain is known for. Outdoor growers in northern Europe can expect to chop by late September — earlier than most photoperiods, which makes Lemon Tree Fast a strong pick for growers in less-than-ideal climates like the UK, Netherlands, or northern France.
6. Drying and curing: Hang whole branches in a dark room at 18–20°C and 55–60% humidity for 10–14 days. Cure in glass jars for at least two weeks. The lemon terps intensify noticeably after a proper cure — don't rush this step.

Lemon Tree Fast vs. the Original Lemon Tree

Short answer — yes, with one trade-off worth knowing about.

The fast version actually yields more, finishes sooner, and sits comfortably within the same THC range. The trade-off? The original Lemon Tree has had years of pheno-hunting behind it, so you might find slightly more variation in the fast version's expression. That said, Matthew Rockwell's breeding work here is tight — the citrus terps and balanced effects come through consistently.
