Frequently Asked Questions

Are these seeds feminized or regular?

Critical Skunk by Mr Nice is only available as regular seeds. This means they will produce both male and female plants, giving you the perfect opportunity to select a phenomenal mother plant for cloning or to collect pollen for breeding.

How much does Critical Skunk yield?

Indoors, under optimal conditions, you can expect massive yields ranging from 650 to 800 g/m² (2.13 to 2.62 oz/ft²). Outdoors, a well-fed plant can easily produce between 725 and 1000 g/plant (1.60 to 2.20 lb/plant).

Does it smell a lot during flowering?

Yes, absolutely. True to its Skunk heritage, this strain produces a very pungent, penetrating aroma during the bloom phase. A high-quality carbon filter is highly recommended if discretion is a priority for your indoor grow.

Is it a good strain for beginners?

Definitely. It is highly resilient, forgives common beginner mistakes, and finishes flowering very quickly (6-8 weeks), which reduces the window for potential issues like mold or nutrient lockouts.

Personal Experience of Pevgrow’s CEO (Alan)

Whenever someone asks me for a strain that guarantees a heavy harvest without the headache of a 10-week flowering cycle, Critical Skunk is always one of my top recommendations. I remember popping a pack of these regular seeds a few years back. The vigor during the vegetative stage was insane, but what really blew my mind was how fast the flowers stacked up once I flipped the lights to 12/12. By week 5, the branches were bending under the weight of the colas.

I highly recommend using stakes or a SCROG net with this one, because the buds get ridiculously heavy. The smell in the grow tent was pure nostalgia—that classic, pungent skunk mixed with a sweet, almost peppery fruitiness. When it comes to the smoke, it is my go-to for a lazy Sunday afternoon. It hits you with a heavy, comforting body stone that just melts you into the couch, but without completely knocking you out. If you want to find a keeper mother plant that will fill your jars to the brim every single run, you need this in your garden.
