Critical Mass

critical mass Mr Nice seedsCritical Mass is a version of Big Bud derived from Afghani and Skunk #1 that, like its origins, delivers huge yields and killer weed.

Developed by Mr Nice seed bank, it’s basically Big Bud on steroids producing massive colas that have to be seen, touched and smelt to be believed :).

Critical Mass seeds are best grown indoors up north as otherwise you risk mould attack despite its short flowering cycle of only 8 weeks. Even indoors though, make sure the growing area doesn’t get too humid and don’t delay your harvest.

Your harvest will be hefty: up to 750g per square metre indoors or a whopping 600g per plant outdoors. Like Big Bud, Critical Mass is one of the most reliable strains for big production, given a little TLC.

Critical Mass seeds are also a top choice for those who like their pot strong. With up to 20% THC content, your smoke will be strong.
