We have nothing but praise for the Black Diesel. Easy to grow both indoors and out, large harvests, THCs of up to 19%, thumping great buds - the list of superlatives goes on and on. Great for beginners and for those who want a lot of crop for their dollar.

Two awesomely potent strains – Bubblegum and Kush – get their freak on in order to create this fantastic indica-dominant specimen. With a high THC content, huge yields, a seriously potent effect and a highly-desired flavour, you’d be mad to miss this one!

This little ripper is 80% indica and highly medicinal. When smoked, she gives a warm and relaxing buzz which is excellent for relieving an array of ailments. This is a great plant to have around when you’re in the mood to chill out.

A brilliant addition to the AK family, this '48 can actually finish in 48 days and produces gorgeous, rock-hard buds full of taste and aroma. It has a sativa-style high backed by THCs of up to 24% so make sure you are ready - the AK 48 doesn't have a safety catch.

Short, squat and immensely strong, the Rhino is one of the most popular strains on the market. It has enormous yields of medicinally-superb buds and almost glows in the dark with it's frosted, diamond-encrusted leaves. A spell-binding plant that will have you begging for more.

The bud from the BCN Diesel feels denser than a collapsed star and gives the plant incredible yields, especially considering the quick flowering times. Buy this if you like it sticky, resinous and thick with diesel-smelling goodness.

Collecting awards like they’re going out of fashion and boasting record-breaking THC levels, can you really afford not to go Greek with Y Griega? Its also 80% sativa which helps create a clear-headed and energetic stone that's great for social occasions. You heard it here first!

A luscious plant with a 25/75 indica/sativa ratio. This baby produces a potent, sativa-heavy high that comes with a side-order of giggles. An excellent puff to get the party started.

Like the Honey B, this plant has a relatively long flowering period and requires a little work from the gardener, but the rewards are worth it. Big, bouncing buds frosted with THC crystals produce a memorably tasty smoke with hints of lemongrass and sweet, dark rum. And the 450g/m2 yields aren't half bad, either!

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.

This Caramel will deliver a brilliant harvest of sweet-smelling bud almost as quickly as a fast auto. There is absolutely no compromise in quality, instead, a faster plant with stickier buds and delightful aromas awaits those that can't, well, wait.

This flavourful strain from Barney's Farm marries large yields with short flowering times and is really easy to grow. Lime-tinted buds produce a cleverly crafted indica / sativa mix with a fairly high THC content. A fascinating plant.

Bubblegum plants are brilliant, let's make no mistake about that, and the XL here makes this a very tempting proposition indeed. Expect fantastic yields of delicious bud from a strong and stable plant, and don't forget the power behind the flavour - 19% THCs mean a seriously strong smoke!

This easy-to-grow, stable plant took first prize in the 2013 San Francisco High Times Medical Cup hybrid category and it’s not difficult to see why! Chem 91, Mass Super Skunk, and Sensi Seeds Northern Lights get jiggy in a ménage-a-trois to create a seed that’s worthy of a place in any collector’s box of tricks.

This sativa-dominant plant combines White Widow XXL Auto and Haze XXL Auto and the results are quite simply awesome. The seeds grow indoors and out and plants can reach anything from 75 - 160cm tall. A monster is born!

The flowering time is longer than usual but the huge yields are worth the wait. Give this brother some room, some tenderness, and your rewards will be heavenly. Honeyed, citrus smoke, buds like marbles and yields of 650 gr/m2 await the patient gardener. Barney’s Farm Honey B feminised cannabis seeds produce a plant you won't stop bragging about.

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!

Short and squat with dense, tightly-packed trichomes and buds that are too heavy for their own good. When these plants grow too close to each other they often coalesce to form black holes - a hazard for the inexperienced gardener.

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 A.M.S from Green House Seed Co. is a relatively new and very mould-resistant strain - the hybrid of a Swiss indica and a Swiss sativa. It will yield up to 700 g/m2 indoors, with a harvest ready in around 8 weeks (9 weeks will coax the most resin). Outdoors, this bad boy will be ready by the end of September and the yields will be even more impressive - up to 800 g/plant!
