He found much to work with in the old school Afghan Skunk genetics of the Mass and his work joyfully led him to his first great success, the Monster Mass!

Critical Lee's work soon took on new legs as he gathered a collective of like-minded breeders who began assembling a new range of super powered Monster Mass-based hybrids. Now these strains showcase the ultimate in Critical Mass genetics, keeping every inch of growth and gram of yield while introducing fresh new flavors and effects.

Essential Strains

Across the board, each and every strain from Critical Mass Collective guarantees super-generous yields with little to no effort required. It’s simply a case of finding your perfect fragrance and flavor profile, along with your preferred level of potency.

Top-selling strains from Critical Mass Collective as of early 2020 include the following heavy-yielding marijuana monsters:


Monster Mass

True to her name, this exceptional strain is a monster in every sense of the word.  Mature Monster Mass flowers are known for releasing the most extraordinary fruity skunk fragrance, with a distinct note of blackberry in the background. It’s a powerful funk that permeates everything in the vicinity, translated into an intensely fruity and sugary-sweet flavor with a note of sharp citrus.

Equally monstrous in her effects, Monster Mass brings on a heavy and incapacitating body stone that often lingers in excess of 4 hours. Expect your entire body and mind to melt into a puddle of pure contentment for the duration, accompanied by the most insatiable munchies you’ve ever experienced. Even if you know what you’re doing, the 22% THC content of a decent batch of Monster Mass is guaranteed to knock you clearly off your feet.


Moonshine Mass

Think of the fragrance of overripe fruit mixed with a curious hint of bergamot and you’re on your way to understanding what Moonshine Mass is all about. She's a strain that’s difficult to compare to anything else out there, for the simple reason that there’s nothing quite like her. Expect a flavor with notes of gin and citrus fruits, with a fair amount of grapefruit and even sandalwood on the exhale.

Ideal as a daytime smoke, Moonshine Mass hits hard with an energizing and euphoric cerebral high that just keeps on going indefinitely. Perfect for injecting a little energy into your afternoons, though edging very closely to overwhelming for the uninitiated. Unless you have a developed THC tolerance, mind-race is almost inevitable with this stuff.


Super Mutant Mass

Bringing that quintessentially classic sour-skunky fragrance to the table by the boatload, Super Mutant Mass is also characterized by a distinct hint of tropical mango floating lazily in the background.  The result of which is a fantastic sweet and sour smoke, which begins with an exotic inhale and leaves you with a spicy aftertaste for the duration.

Like her counterpart above, Super Mutant Mass is synonymous with the kind of lifting and energizing high that’s perfect for daytime use. She's also a notorious strain for bringing on the munchies, so you’ll want to keep plenty of snacks within easy reach. Though hard-hitting, Super Mutant Mass isn’t nearly as overwhelming as Moonshine Mass and is therefore great for less experienced smokers.


Psychotropic Mass

Spicy and fruity with plenty of pine notes in the background, Psychotropic Mass is exceptionally refreshing and uplifting on the nose. Set light to the stuff and you’re treated to a veritable bouquet of sweet citrus flavors with an interesting hint of caramel on the exhale, making for a sophisticated and complex experience you can’t help but love.

Psychotropic Mass is one of a handful of strains from these guys to feature an elevated content of CBD, making for a potent yet relaxing Indica strain that’s beautifully balanced and easy to enjoy. By far, one of the best medicinal strains to come out of Critical Mass Collective’s labs so far.


Purple Skunk Mass

Also well worth checking out and bursting with bag appeal, Purple Skunk Mass has an exceptionally exotic fragrance with tones of hash and a strong hit of licorice in the background. On the inhale, Purple Skunk Mass is a surprisingly sweet and fruity strain with prominent passion fruit flavors, leaving behind a sweet and hashy aftertaste that’s deeply satisfying.

Expect a sense of immediate and soaring euphoria after just one or two hits, which gradually gives way to a feeling of creative energy that lingers for hours on end. Purple Skunk Mass is simply superb when you’ve mundane tasks you want to inject a little enjoyment into, or you’re heading out and about to do pretty much anything at all.
