Every once in a while, a pair of strains arrives that feels less like a new product and more like a homecoming. This season, we welcome two absolute heavyweights into the Seedsman collection – Seedsman Sour Diesel and Seedsman Green Crack. Both photoperiod feminised, both legendary in their own right, and both now refined, stabilised, and ready for growers who demand the very best.
These aren’t just new additions. They’re cultural staples, re-engineered with Seedsman’s trademark precision. If you love high-octane sativas, terpene fireworks, and plants that deliver the goods both in the soil and in the jar, you’re about to meet your next favourites.
Seedsman Sour Diesel
Seedsman Sour Diesel takes its rightful place alongside Seedsman Sour Diesel Auto, and draws from the iconic Chemdawg 91 line with influence from Super Skunk – a heritage that has defined the “diesel” category for decades. This lineage is responsible for its unmistakable fuel-and-citrus punch and its famously uplifting cerebral profile. Sour Diesel made its name in the 1990s on America’s east coast, and has been a staple in joints, bongs, and blunts ever since thanks to its defining traits – all of which are present and correct in Seedman Sour Diesel.

How Seedsman Sour Diesel Grows
A sativa-dominant photoperiod with classic Diesel structure, Sour Diesel thrives in warm, dry environments and responds beautifully to training techniques like SCROG or LST. Expect dense, resin-heavy colas and vigorous vertical growth.
Indoors, take care to keep airflow strong and humidity controlled to maximise trichome production. Outdoors, Sour Diesel loves plenty of sun and space to stretch. Flowering time is 9-11 weeks, and yields are superb.
Terpenes, Aroma, and Flavour
Sour Diesel is famous for one thing above all else: that smell! A pungent fuel aroma layered with lemon, spice, and pine notes is a defining characteristic any Sour Diesel, and those qualities present and correct in abundance here. It’s loud, it’s unmistakable, and it's exactly what Diesel lovers crave. The flavour follows suit with sharp, tangy, invigorating bursts of citrus that makes tongues tingle and mouths water.
Potency & Effects
Sour Diesel is notoriously heavy-hitting, and with THC levels reaching a lab-verified 24%, this is a strain built for energy, creativity, and mental lift. Expect a fast-acting, hard-hitting euphoric high that sparks conversations, inspires creativity, and fills you with big ideas. Sour Diesel is known as a daytime classic for a reason – it's uplifting and highly motivating for the body and mind.

Seedsman Green Crack
The Seedsman collection has been home to the ever-popular Green Crack Auto for some time. Now, we welcome the photoperiod version of Green Crack into the stable. Descended from the legendary Skunk #1, the backbone of genetic excellence in many of today’s greatest strains, and crossed with a hardy Afghani line, this combination preserves the original’s electric sativa energy while adding robustness, resilience, and that unmistakable tropical terpene profile.
How Seedsman Green Crack Grows
A vigorous, sativa-dominant photoperiod, Green Crack thrives in warm, dry climates and shows strong resistance to humidity stress. Indoors, it performs exceptionally well under SCROG, producing a large central cola supported by dense side branches.
Keep your aroma control game on A+ for this, the bouquet is powerful. Outdoors, Green Crack will reward growers with impressive yields and classic old-school vigour.
Terpenes, Aroma, & Flavour
Green Crack is a terpene celebration – bright mango, sweet citrus, and tropical fruit notes that hit the nose before you even break the buds apart. Once cured, it’s a scintillating experience - refreshing, juicy, and instantly recognisable. The flavour is equally vibrant, making it a favourite for daytime connoisseurs. Green Crack brings the kind of flavour you'll rave about to all your friends, and you can't keep your head out of the stash jar, whether it's to admire the beauty of the buds or just to catch another whiff of the unbelievable terpy aromas.
Potency & Effects
This strain is all about the energy. Expect an uplifting, clear-headed, motivational high that’s perfect for creative work, outdoor adventures, or simply powering through the day. Green Crack is fast-acting, long-lasting, and beloved for its ability to sharpen focus without overwhelming the senses.
