Guillotine Auto

Guillotine Auto Cannabis Seeds by French Touch Seeds

Guillotine Auto is a feminised autoflowering cannabis seed from French Touch Seeds — a 50/50 Sativa-Ruderalis cross bred from NYC Diesel and Ruderalis genetics for speed, flavour, and sheer bud density. When harvest day rolls around after just 60 to 65 days of flowering, you're looking at plants that resemble one solid cluster of buds from top to bottom. If you're short on space or patience, this is the seed that delivers.

Why Guillotine Auto Seeds Deserve a Spot in Your Garden

French Touch Seeds built the Guillotine Auto with a specific brief: fast flowering, compact size, and flavour that actually holds up against photoperiod strains. They crossed their NYC Diesel — a Sativa known for its sharp citrus-diesel nose — with Ruderalis genetics, then worked the line until they hit a stable 50/50 equilibrium. The result is their very first autoflowering variety, and it's a confident debut.

The NYC Diesel parentage comes through in the flavour profile. Expect a fuel-forward bite with a citrus undertone — the kind of terpene expression you don't always get from autoflowers. We've seen plenty of autos that trade flavour for speed, but French Touch clearly weren't willing to make that compromise. The Ruderalis side handles the clock: no light schedule changes needed, no fuss with timers. She flowers based on age, not photoperiod, which makes her a solid pick for guerrilla grows, balconies, or any setup where simplicity matters.

One honest note: not every Guillotine Auto plant stays small. French Touch Seeds themselves acknowledge this — while the strain was bred for compact growth, some phenotypes stretch more than others. If you're growing in a tight space, be ready to do a bit of low-stress training on the taller ones. It's a minor trade-off for a plant that otherwise practically grows itself.

Guillotine Auto Grow Specs and Flowering Time

Guillotine Auto finishes flowering in 60 to 65 days from the start of bloom, making it one of the quicker options if you want to turn around a harvest without months of waiting. Here's what you're working with:

The 50/50 Sativa-Ruderalis split means you get the structural vigour and flavour complexity of a Sativa parent without the long flowering window that usually comes with it. Ruderalis keeps the timeline tight and removes the need for light cycle management. From seed to harvest, you're looking at roughly 75 to 85 days total — germination, vegetative growth, and flowering combined.

How to Grow Guillotine Auto Seeds

Autoflowers are forgiving, and the Guillotine Auto is no exception. That said, a few things make the difference between a decent harvest and a plant that genuinely looks like one massive bud. Here's the approach we'd take:

1. Start your Guillotine Auto seeds directly in their final container. Autoflowers don't love transplanting — the stress can stunt growth during a life cycle that's already short. A 7 to 11 litre pot works well for most setups.
2. Use a light, airy growing medium. A mix of coco coir and perlite, or a quality light-mix soil, gives the roots room to expand quickly during the brief vegetative phase.
3. Keep your light schedule at 18/6 or 20/4 from seed to harvest. Since Guillotine Auto flowers based on age rather than light cycle, there's no need to switch to 12/12. More light hours means more energy for bud production.
4. Go easy on nutrients in the first 2 weeks. Autoflower seedlings are sensitive to overfeeding. Start at quarter strength and build up gradually as the plant enters its flowering stretch.
5. Watch for the taller phenotypes. If a plant starts stretching beyond your canopy, gentle low-stress training — bending and tying the main stem — keeps everything even without the stress of topping, which autoflowers don't always recover from quickly enough.
6. Harvest when 60 to 65 days of flowering have passed and trichomes show a mix of milky and amber under a jeweller's loupe. The bud structure on Guillotine Auto is dense, so check the lower buds as well — they can hold moisture and need good airflow during the final weeks.

Guillotine Auto for Guerrilla Growing

This is where the Guillotine Auto really earns its keep. French Touch Seeds specifically designed this strain with guerrilla growers in mind — the kind of outdoor cultivators who need a plant that stays discreet, finishes fast, and doesn't demand weekly visits. The autoflowering genetics mean she'll flower regardless of the season's light cycle, so you can start her in spring or summer without worrying about photoperiod triggers.

Her compact stature helps her blend into natural surroundings. Tuck a few Guillotine Autos into a sunny clearing, give them decent soil, and nature handles most of the work. The 60 to 65 day flowering period means you're in and out before autumn rains set in — a real advantage in northern European climates where late-season moisture can wreck an outdoor crop with mould.

The productivity is the surprise here. For a plant this small and this fast, the yield is genuinely impressive. At harvest, the entire plant looks like one dense column of buds rather than a branchy structure with scattered flower sites. That's the NYC Diesel influence — tight internodal spacing combined with vigorous flower production.

Flavour and Aroma Profile of Guillotine Auto

The NYC Diesel parent is one of those strains that stamps its character onto everything it touches, and the Guillotine Auto is no different. Crack open a cured bud and you'll catch that unmistakable diesel funk — sharp, almost chemical, but in a way that's genuinely appealing rather than off-putting. Underneath it sits a citrus brightness, like lemon zest mixed with grapefruit peel. It's a terpene profile that fills a room.

During the final weeks of flowering, the plants throw off a noticeable aroma. If you're growing indoors, a carbon filter is non-negotiable unless you want your entire flat smelling like a fuel station crossed with a citrus grove. Outdoors, the smell dissipates more easily, but close neighbours might still notice. Something to factor in for balcony growers.

The flavour translates well after a proper cure. Give the buds at least 2 weeks in glass jars, burping daily for the first few days, and the diesel sharpness mellows into something smoother while the citrus notes become more pronounced. It's the kind of taste that reminds you this isn't just another generic autoflower — there's genuine breeding work behind it.

Guillotine Auto vs Other Autoflowering Strains

The autoflower market is packed, so where does the Guillotine Auto sit? We'd compare it most directly against strains like Auto NYC Diesel or Diesel Auto from other seed banks. The key difference is the breeding approach: French Touch Seeds didn't just slap Ruderalis onto an existing Diesel cut and call it done. They worked the cross until the genetic ratio stabilised at a clean 50/50 split, which shows in the consistency of the plants.

The 60 to 65 day flowering window puts Guillotine Auto at the faster end of Diesel-derived autoflowers. If speed is your priority and you don't want to sacrifice the Diesel flavour profile, this is the strain we'd point you towards. The only caveat — and we've mentioned it — is the occasional taller phenotype. If absolute uniformity matters to you, be prepared to manage one or two outliers per batch.
