Mr. Nice Seedbank at Cannapot

If you are into quality cannabis genetics, you have probably heard about Mr. Nice Seeds. This seedbank has a bit of a legendary status. It was started by Howard Marks, better known as “Mr. Nice,” along with his very good friend and legendary breeder Scott Blakey (better known as Shantibaba). These are people who have been deep in the cannabis scene for decades, and they are known for keeping their work true to the original genetics rather than chasing quick trends. When you look at the selection on Cannapot, you can see that it is not just a random mix of strains. It is a line-up that has been built with intention. Each one has a history behind it, and you can usually trace the lineage right back to some of the most well-known classics.

Black Widow cannabis seeds
Black Widow is what many people consider the original White Widow before the name got copied by everyone. This strain is known for producing a lot of resin, with a flavour that mixes earthy tones and a gentle sweetness. The effect is strong, starting with a clear mental lift before it settles into a more relaxed state. It is one of those strains that people remember, and for good reason.

Critical Mass cannabis seeds
If you have heard of Big Bud, you might be familiar with the reputation for large yields. The Critical Mass is a reworked version of that idea, keeping the generous production but fine-tuning the aroma and flavour. The scent has a sweet side with a touch of skunk, and the taste is smooth all the way through. It is a dependable classic in the Mr. Nice line.

Devil cannabis seeds
The strain called Devil stands out because of their look. As they mature, the plants often develop deep red shades that are hard to miss. The aroma leans toward earthy and spicy, with a small hint of fruit hiding in there. The overall effect is steady and calming, something that people often enjoy later in the day.

Walkabout cannabis seeds
This one is interesting as well - Walkabout is actually a mix of different sativa and hybrid genetics, all in one pack. That means you never quite know what you will get until they grow. Some people really enjoy that element of surprise. You could end up with several different aroma profiles and effects from a single purchase.

U2 (Early Queen x Haze)
Fans of haze often find the U2 strain to be a nice middle ground. The Early Queen brings balance, while the Haze adds complexity to the scent with spice and a bit of sweetness. The effect is more on the uplifting side, good for when you want energy rather than slowing down.

The Doors cannabis seeds
This great type of marihuana takes Afghan Haze and mix it with a pure Haze male. The result is aromatic, with a floral and spicy smell that feels quite distinct. The high is head-focused and creative, and it has a bit of that classic sativa length to it.

What makes Mr. Nice Seeds worth looking at
The main thing with the Mr. Nice Seedbank is the history and the authenticity. These are not thrown-together hybrids made just to sell something new. The breeders have held on to old-school parent plants that are rare now, and they keep those genetics alive in each strain. When you buy them through Cannapot, you are getting access to those original lines and the work of people who have been shaping cannabis breeding for decades.
