This Kush, from the border of Afghanistan and Pakistan, shares its history with some of the classiest strains ever produced. High-quality breeding techniques have led to a hard-working plant that does well even in poor conditions. She is stocky and well-built and perfect for both Sea of Green and Screen of Green gardens, growing thick green buds on chunky stems. She has tangy, curried aromas that are typically Kush and her high yields have made her one of the most popular marijuana seeds on the market.

The Acapulco Gold stands up well to the original, with good, solid buds and a christmasy sprinkle of red and crystal gold. With a large indoor yield of around 500 g/m2 and a height ranging from 70 - 80cm, this is a sizeable and productive plant. The indoor flowering time of 70 - 75 days is not too shabby either - prepare to enjoy a great set of high-THC buds that race up in double-quick time.

This is a great hybrid of Skunk #1 and the award-winning Amnesia Haze. It has strength and tenacity and produces strong, spindly colas. A flowering cycle of 9 to 10 weeks will amaze the grower every time one of these beauties pops through the ground. Great for beginners or as back-up to a chancier crop.

This curious indica-dominant specimen has an effect as mind-boggling as its name. Its appearance might be kind on the eye but don't be fooled - this one's as strong as they come! Trust us - you do not want to try this hardcore strain unless you're up for a true psychedelic, and maybe hallucinogenic, experience!

This 100% indica specimen has a THC content of 24% and can yield harvests of up to 700 g/m2 indoors. That's what you call a bad ass mutha!

A hybrid of Big Buddha Cheese and the evergreen Blueberry, Blue Cheese is a delightfully tasty grafter of a plant. It produces an aroma evocative of an expensive restaurant cheeseboard where veiny gorgonzolas mingle with apple, celery and soft blueberry to produce an unforgettable bouquet. She is a tough stump of a plant, small and sticky and with a relatively short flowering time.

This is a great new product from Barney's and one that has received rave reviews so far. The Blue Cheese medical cannabis strain is a hybrid cross between Blueberry and UK Cheese. It's a smooth strain with euphoric and psychedelic effects and this autoflowering version takes all of the hard work out of the grow.

Barney's Farm Blue Mammoth Auto is a powerfully-built, autoflowering rock star. Give it a pair of Ray-Bans and watch the girls swoon...

This mostly-indica strain grows well indoors and out and has a flowering time of 53 days. It’s most appreciated for its unusually spicy-yet-fruity aroma and flavour – and the buds are as frosty as a winter wonderland!

This is a fantastic strain from Barney's Farm with all of the quality, flavour and robustness we have come to expect from one of the world's leading breeders. The Blue Shark is at the forefront of a new breed of seed that combines superb medical qualities with sublime recreational enjoyment.

The CBD Critical Cure is almost a one-stop-shop for those looking for an effective medical marijuana strain. The pain relieving properties are enough to sell the plant alone, but the flavours, yields and honeyed aromas make for an almost perfect specimen. The CBD levels of 8% are rarely matched across any strain, and the healing potential will make this one of the most sought-after plants for years to come.

Standing at just under a metre, this relatively new strain will flower in eight weeks into an indica-dominant gem of a plant. The yields are high and it is a stunner to look at, with trichomes like anemones worming their way up the central stem. High THCs and CBDs make you wonder where it has been all your life.

This great product from Barney's Farm has received critical acclaim the world over. It won first prize at the Cannabis Cup in 2014 and is rapidly becoming the must-have product for any discerning grower. The balance between the flavoursome Cookies and the power, strength and undeniable bling of the Rolex OG has been achieved beautifully. An instant favourite.

A tough Crimean hash plant has been crossed and softened with the subtle fruitiness of a Blueberry to produce a unique and explosive taste sensation. The flavours of light mint, tangy lemon and fresh rosemary might tempt you to smoke it with your Sunday roast lamb.

The Critical Kush is an expert cross of the Critical Mass and OG Kush. The scientists at Barney's have really earned their money with this robust, dynamic and powerful indica plant, promising huge amounts of capital Kush. The pungent bush is covered in resinous crystals protruding from sticky ribs and the aroma is unmistakably herby. Prepare yourself for a bumper harvest and pinch yourself at the miraculous, flowery shower this new hybrid presents.

The famous Critical Mass has been crossed with a ruderalis to produce a clever strain capable of flowering within 20 days of planting and finishing in just 8 - 9 weeks. Look forward to a dense forest of thick indica with rich, peppery scents.

Named in honour of our hero, the brilliant cannabis advocate, researcher and author Dr. Lester Grinspoon, this is a pure heirloom sativa. The plant grows thin and tall and requires a longer flowering time. When mature, the colas look like compact green and red-brown beads, loosely strung on thin stems with a dusting of THC crystals. The fragrance from the buds is of sumac and lemon; the smoke is light and tangy with citrus and tropical fruit aromas. Barney's Farm Dr. Grinspoon feminised weed seeds are great medical marijuana seeds and offer a strong, long-lasting, energetic and cerebral high. Old-school sativa of the highest order.

The original G13 was an amazing strain, but crossed with the Hawaiian sativa it's now a compact plant with an extraordinarily dense mane of flowers. Lively up yourself with this eye-catching beauty!

This is a wickedly enjoyable bud with plenty under the hood. It thrives pretty much anywhere and has aromas that are only slightly less pleasurable than the long-lasting, fruity flavours. It flowers quickly, yields heavily and delivers a high-THC stone worthy of any of the great Apes.

An original blend of Grapefruit, Skunk#1 and Ruderalis make this an energetic yet reliable auto-flowering 60 day miracle. The Grape Muerto is a short plant, fully indica, and the producer of some tight, powerfully musky buds. A relatively new strain, easy to grow and great for beginners.
