Mr. Nice is the seed bank built on the genetics Shantibaba and Nevil kept when they left Greenhouse Seeds in the late '90s. Everything here is regular (not feminised), sold in packs of roughly 15 seeds, and bred from parent lines that shaped the entire Dutch coffeeshop scene — Skunk #1, Northern Lights, Afghani landraces, true Haze, the G13 clone. If you've smoked award-winning Dutch weed in the last 30 years, you've smoked these genetics in some form.
We've stocked Mr. Nice since the early 2000s. The catalogue barely changes, and that's the point — these are proven lines, not seasonal hype drops. Shantibaba still runs the breeding. No autoflowers, no feminised shortcuts, no flavour-of-the-month crosses.

How to Choose Your Mr. Nice Seeds
New to regular seeds? Start with Shit or Shark Shock. Both are forgiving, finish in around 8 weeks, and give you a proper introduction to what Mr. Nice genetics feel like without the 10+ week flowering commitment of the Haze lines. Order a pack of 15, pop them all, cull the males once they show, and keep the best female — that's the workflow regular seeds are built for.
Growing outdoors in a short European summer? Early Queen is the one. It finishes photoperiod flowering in 6 weeks flat, which is why growers in the UK, Netherlands, and Germany have been buying it since the '90s. For indoor commercial setups, Critical Mass and Critical Skunk are the classic picks — dense, heavy, reliable.
Experienced growers chasing flavour over yield should shop the Haze shelf. Mango Haze and Super Silver Haze need patience (10–11 weeks flowering) and proper light, but the terpene payoff is what made these strains famous. G13 Haze is for experts only — long flower, tall stretch, but loaded.
Honest note: regular seeds mean roughly half will turn out male. That's a feature if you're breeding or selecting mothers, and a hassle if you just want to grow flower. If you've never separated males from females, get Shit or Shark Shock first — forgiving plants are more fun to learn on than fussy ones.
Frequently Asked Questions
Are Mr. Nice seeds regular or feminised?
All Mr. Nice seeds are regular — roughly a 50/50 male-to-female ratio. Shantibaba doesn't do feminised seeds on principle; he believes stable genetics come from traditional breeding. Every pack we stock contains around 15 regular seeds.
What's the best Mr. Nice strain for beginners?
Shit and Shark Shock are the two we'd point a first-timer at. Both finish in about 8 weeks, handle beginner mistakes without dying, and produce properly good weed. Critical Skunk is the next step up if you want bigger yields in the same timeframe.
How many seeds come in a Mr. Nice pack?
Roughly 15 seeds per pack across the whole Mr. Nice catalogue. The exact count can vary by a seed or two — that's normal for regular seeds sold by weight rather than count.
Who breeds Mr. Nice Seeds?
Shantibaba and Nevil founded Mr. Nice after leaving Greenhouse Seeds in the late 1990s. Shantibaba still runs the breeding programme, which is why the catalogue stays small and the genetics stay stable — no flavour-of-the-month crosses, just the lines they've refined for 25+ years.
Which Mr. Nice strain has won the most awards?
Super Silver Haze and Black Widow are the two big cup winners in the catalogue — both from Shantibaba's Greenhouse-era work in the mid-to-late '90s. Super Silver Haze took multiple High Times Cannabis Cup titles; Black Widow won the Cup in 1995 under its original name.
