Cannabis Seeds for Ireland — Genetics That Finish Before the Autumn Rain

A flowering time is not a harvest date. For a photoperiod it is the span after you flip, or after natural daylength drops far enough outdoors — so the useful sum is your realistic flip date plus the flowering window, checked against when the autumn weather closes in where you are. Outdoors in Ireland that sum rarely leaves much slack: a plant flipping with the natural daylength in August has to finish inside about eight weeks to beat the October rain.

Autoflowers behave differently. They run on an internal clock, usually ten to twelve weeks from germination regardless of daylength, which makes them predictable to schedule and far easier to fit into a short season. That predictability, rather than any yield advantage, is why they suit an Irish season — started in May, an autoflower can be harvested in August, well clear of the weather that ends the year.

Feminised cannabis seeds are bred using techniques that ensure virtually every plant develops as female — the sex that produces cannabinoid-rich flower. Without feminisation, roughly half your plants would be males that need identifying and removing before they pollinate your crop. Our feminised collection spans over 1,000 varieties, from compact indica cultivars suited to tight grow tents through to stretchy sativa-dominant hybrids that thrive outdoors. The one consideration: feminised photoperiod strains require a deliberate shift in lighting — from 18 hours of light during vegetative growth to 12 hours to trigger flowering.

Autoflowering seeds incorporate ruderalis genetics that cause plants to begin flowering based on age rather than light exposure. Most autoflowers transition to bloom roughly three to four weeks after germination and reach harvest in eight to twelve weeks total. They stay compact — typically 60 to 120 centimetres — and tolerate the kinds of mistakes that derail photoperiod grows: a missed feed, an imprecise pH, or a light cycle broken by a power cut. That tolerance, not a yield advantage, is the reason they are usually the right first grow.

Irish growing conditions vary by degree rather than by kind, and the axis is rainfall and shelter rather than temperature. The eastern counties are the best outdoor odds in the country: roughly 750 mm of rain a year, the highest sunshine totals, and shelter from the prevailing south-westerlies in the lee of the uplands. The south and the Munster coast have the mildest winters and the longest frost-free season, traded against more rain and higher humidity through the flowering weeks. The Atlantic west and north-west take 1,200 to over 2,000 mm along with the wind and the fewest sunshine hours — polytunnel and greenhouse country, honestly stated. The midlands and inland border counties have the widest frost window at both ends and heavy, slow-draining ground. Choose on finishing time first, then on everything else.

This site publishes no yield figures of its own, and no customer-reported averages, because it has none to publish. What appears on a strain page is the figure the breeder or a reference source published, shown with its source. Where none exists the field is blank. Treat any per-plant number — here or anywhere — as a ceiling under that grower's conditions rather than a forecast for yours: pot size, light, feeding and training move the result far more than genetics alone.

Orders ship in plain, unbranded outer packaging— no logos, no company name on the outside, and no description of the contents. Delivery is tracked to addresses in all 26 counties. Outlying towns and farm addresses take longer than the metros.

Experienced cultivators growing for maximum strength gravitate toward high-THC genetics that test above 25%. Strains like Gorilla Glue, Bruce Banner, and Girl Scout Cookies dominate this tier. Growers prioritising therapeutic benefit without heavy psychoactive intensity should explore CBD-dominant seeds that produce plants with 10 to 20% cannabidiol and minimal THC. For a middle path, balanced 1:1 THC-to-CBD hybrids sit between the two. Our calmer-effect collectionis grouped from breeder and grower effect reports — those are descriptions of reported experience, not medical claims, and nothing on this site is offered as a treatment.

Seeds keep best cool, dark, dry and sealed. An airtight container with a desiccant sachet in a fridge is more than adequate; the thing that actually degrades viability is repeated temperature swing and the condensation that comes with it, so a container opened daily in a warm room is worse than one left closed in the cold. Avoid the freezer. Label the container with the strain and the date you received it — a year on, that is the detail nobody remembers.

For a first grow, the useful filter is forgiveness rather than potency: an autoflower removes the light-cycle decision entirely, and a shorter plant is easier to manage in a tent or on a balcony. Start from the autoflowering range and sort by finishing time, and for an outdoor run anywhere in Ireland treat anything over twelve weeks from germination as optimistic.

• Novice cultivators — Autoflowering feminised genetics: no light-cycle decision to get wrong.
• Intermediate growers — Feminised photoperiod varieties like Girl Scout Cookies, OG Kush, White Widow, Blue Dream, where you control veg length and final size.
• Advanced cultivators — High-THC strains above 25%.
• Outdoor specialists — varieties selected for structure that copes with wind and an open flower that dries rather than holds moisture through a humid summer.
• Connoisseur-grade — OG Kush, Bubba Kush, Granddaddy Purple, exotic crosses.
