Critical Mass is a potent indica marijuana strain made by crossing Afghani and Skunk #1. In small doses, this strain will have you feeling creative and calm. In large doses, you'll likely find yourself feeling sleepy and in a couchlock. Critical mass gets its name because of its ability to reach "critical mass" in terms of growing. When growing, branches of this strain tend to snap off from the heavy weight of its buds - which are dense, heavy and tasty. The downside of Critical Mass is that this strain is particularly susceptible to mold, so growers have to be extra cautious with humidity. Flowering time for Critical Mass is approximately 6-8 weeks. This strain originated from the breeder Mr. Nice Seed Bank.

Firstly, I just want to point out that leafly does not allow paragraphs in any review, so my neatly organized reviews from before ended up being a one-long-cloud-of-text mess. So this time, I am going to use a lot of spaces to at least make the sections from separate from each other. So here we go: 1) VAPING: I vaped this strain with a vaporizer (TinyMight 2) in order to get as clear of a taste as possible. But I still sometimes struggle with recognizing the tastes correctly since I am still relatively new to weed. 2) TASTE: All in all, this is my relationship with skunky strains: Too much skunk = I don't like it. And Critical Mass is pretty skunky... If it was just that, this strain would be discarded for me. However, Critical Mass also has some of those woody, piney tones that I like. It's also very earthy, sometimes maybe too much. Strong and pungent too. And since this pungent smell is combined with those underlying wooden/pine tones, the resulting flavor is much better than I expected. The pine there, hmmm, yummy! Also would describe it as spicy and slightly sweet. If there was less skunk, I would rate higher. Taste score 6.1/10 3) EFFECTS: This strain can smack! Heavy couch lock, my body refuses to get up (it really could be smaller to be honest). Pure indica effects. Also quite aroused. Heavy euphoria. Moderate dizziness (fun) that transitions into heavy dizziness (slightly uncontrollable) from time to time. Massive body high. I might have gone a bit too much with the hits this time - like yeah, but still not too much for it to do this! I sometimes take a few more hits, but I rarely have such a strong couch lock like now. Overall it's a very strong and trippy high, but not really the kind that I search for (I prefer sativa-dominant hybrids and hybrids in general). But ok. I will give it another try in two hours. AFTER TWO HOURS: I can still partially feel the effects from before, but the couch lock is now gone. So here we go again, cheers, guys!.... AFTER 30 MINUTEES MORE: Nice, just a body euphoria. One more hit... Flowing, bruh. Strong body high, couch lock is back. Also quite horny. But once again, I am more of a sativa-hybrid guy. I am glad that the dizziness is lower this time, which makes it even pleasant, actually the slight dizziness is the most fun part of this. But still, this strain is way too relaxing. Effects score 4.5/10 4) VARIANT: It's good to mention that I vape this in the form of THC-X. But the molecule is very similar to the normal THC, so the effects and taste will be most likely very similar too. 5) FINAL SCORE: 5.3/10

Grew this myself and my buddy keeps asking for more, it has become one of his favorites. I smoked some and hello couch and I was awakwe but not present for about 10 minutes, no recollection of those 10 minutes at all. After that, happy, no pain, no worries, and watched a movie I think and next I know is waking up refreshed the next morning. My buddy is high strung and it totally relaxed him and no insomnia or pain or worries. We call it "This is pot". Just earthy, natural potent pot, simple but highly effective. Very nice Indica.

This strain is probably 10x better on a rig than in a cart but this one has lots of earthy, spicy notes, nutmeg allspice. that’s all I can really get from the cart unfortunately
