Shit (Mr. Nice) regular

Most people who type "mr nice seeds" into Google are picturing a normal feminized pack. That's the one thing to get straight here, because these packs behave differently in the tent and reward a different kind of grower.

Regular Seeds Means Males, and That's the Whole Point

A regular pack gives you roughly a coin-flip split of males and females. Breeders want that. If you're keeping a mother, chasing a keeper phenotype, or making pollen for your own cross, males aren't waste, they're the raw material. Walkabout is sold on that basis: pick your own keeper out of the mix and take clones off it.

Here's the honest catch. If you only want flowering females and don't fancy sexing plants and pulling males out at week two, regular seeds will annoy you. Go for a feminized pack from the wider cannabis seeds range instead. Skunk XL, for example, does 650 grams indoors in 7-8 weeks with no males to cull.

Nevil and Shantibaba's Handwriting in the Parent Plants

Shantibaba and Neville: the breeders behind the name

Our product texts credit Nevil and Shantibaba as the breeders behind these strains, and you can read their taste in the parents. Nevil was the collector who chased down the early Dutch keepers; Shantibaba was the grower who put them to work in a breeding room.

From Green House and Sensi to Mr Nice

Nevil's earlier work fed the Sensi Seeds catalogue, and Shantibaba ran breeding at Green House before the pair set up Mr Nice together. The seedbank became the place where they kept working with parent plants they already trusted. That is why several strains here look familiar under a different name.

Mr Nice seedbank genetics explained

Skunk #1, Northern Lights #5, White Widow, the original Haze and old Afghani landraces turn up again and again. Shark Shock is Skunk #1 crossed with White Widow. Shit is an ancient Afghani over an original Skunk, and later got sold by plenty of other breeders as Skunk #1.

Landrace and heirloom lines in the catalogue

The Afghani and Haze material behind these packs is heirloom stock, kept close rather than hybridised out of recognition. That is what gives the indicas their hash character and the hazes their long flowering. Super Silver Haze, Medicine Man and Black Widow all carry award-winning reputations from the 90s onwards.

Nordle and the Naturals, Named After the Hash

Nordle comes out of the Naturals, the Old School Genetics line, and the name nods to the Afghani hash Nevil and Shantibaba called Nordle. Ortega follows the same thinking, a straight NL#1 x NL#5 indica with roots in the mid-80s. It smells peppery, tastes of berries and settles you into the sofa, so keep it for evenings when nothing needs doing.

Flowering Weeks and Grams per Square Metre

Critical Skunk is the sprinter, 6-8 weeks for 650-800 g/m². G13 x Skunk stays short and still pulls 500-650 g/m² in 7-9 weeks. NL5 x Afghan lands 500-750 g/m² in the same window, and Dreamtime runs 400-550 g/m² after 60-plus days.

Super Silver Haze: the cup winning sativa

Super Silver Haze is the trophy cabinet name here, and it still asks for 9-10 weeks of flowering. Give it headroom and patience for that airy Haze structure. Mango Haze wants the same 9-10 weeks and Black Widow about 10, with Mango Haze paying you back in one resin-caked main cola that reeks of sweet mango.

Critical Mass: heavy yields, short flowering

Critical Mass is the pick when you want weight without a long flowering stretch, and it builds solid, top-heavy colas that need support. Watch the dense ones, though. Critical Mass, NL5 x Afghan and G13 x Skunk pack buds tight enough to trap moisture, so keep humidity down late in flower.

How the Seeds Reach Your Door

Packs go out in plain, discreet packaging with fast UK shipping, and stock moves often enough that you're not buying seeds that have sat in a drawer for years. Store what you don't sow in a cool, dark spot in a sealed container.

Picking your first one? Spice finishes in around 8 weeks and grows fast and stable, though it stretches, so plan for a SOG or ScrOG. Shark Shock also does 8 weeks and forgives beginner mistakes.
