A strain named for its copious amount of buds, if ever a marijuana could be considered a “warm blanket”, Critical Mass would be it.

With such noble parentage – Critical Mass marijuana seeds are the marriage of the world-renowned Afghani and Skunk #1 strains – these indica-dominant seeds, though remarkably high on the THC range (anywhere from 19-22%), can be your evening’s best friend, offering soothing relaxation and the kind of pain relief that can help ease chronic insomnia and headaches.

Earthy and sweetly pungent, our Critical Mass feminized marijuana seeds are slightly more complex to grow, and require some careful attention to detail, specifically in the area of humidity: because the buds of this variety tend to be dense, and there is a heavy leaf to flower ratio, Critical Mass plants can be susceptible to mold. But, with the right equipment and some patience, after 50-60 days of flowering, the intrepid gardener can boast about an impressive yield of upwards of 600-700 g/plant.

Wrap yourself in the soothing, therapeutic warmth of Critical Mass – order top quality marijuana seeds now!

    If your wondering where to get your cannabis seeds from, Pacific Seeds is a great online source. This is my third order and I’ve always been very pleased with the quality of seeds and the fast, professional delivery. Critical Mass mj is one I’m now growing on the regs – the sweet, kind of soil-like smell is divine! Also, once I got the hang of growing CM, I got an awesome yield – lot of bang for my buck! Definitely will order Crit Mass from PSB Seeds again.

    I’ve turned into a little bit of a critical mass-hole because of how awesome this weed is. Quick shipping and easy germination (thanks pacific seed bank) and then after a few weeks of veg and about 8 weeks of flowering indoors I’ve been blessed with a bountiful yield – approx 700 g per plant. It’s definitely more than enough for one person to smoke and it’s kept me in chronic since I harvested for sure. Real nice, mellow, and relaxing high throughout. Don’t regret ordering these seeds at all.

    I love this weed! Have been growing weed in my basement for a few years now so am familiar with the art of the herb if you know what I mean. Had a super smooth experience ordering online from PSB, and these plants really know how to produce. Took em about 3 months but these trichomes are huge and yellow and the size of a softball! Getting stoned off this stuff has been a nightly routine for some time now, and it’s hella relaxing. A great “after work” weed, and always fun to share with friends.

    Word to the wise — beware of mold. I didn’t take the proper precautions and lost some weed, much to my regret. This is one of my favorite strains. Great for headaches, puts me to sleep, awesome with pain relief….it really is a fantastic strain to grow if you’ve got the knowledge and the right tools. Just be careful of mold, friends.

    Stoked about how this strain turned out. Not for the newbie gardener, these buds required some extra TLC. But wow, did I get a lot of cannabis from these seeds! Everything went smoothly with ordering the seeds and with delivery. All of them sprouted, and thanks to some helpful tips from Pacific on the Critical Mass page, I knew I needed to watch these ladies for mold. If you have the experience, time and attention to give to this strain, you’ll be happy with the weed you get from it.

    I vaped Critical Mass and then turned on Mozart’s piano concerto no. 21, and I think I experienced this weed the way it was meant to. Maybe it was the Mozart. Maybe it was the Critical Mass. But I was lulled into a soft, gentle relaxation that quite literally erased all of my troubles. I felt peaceful, blissful, and creative. I highly recommend this strain, and even more strongly recommend smoking it along with your favorite album. I think I experienced music in a whole new way while smoking this fantastic mj.

    This is the kind of weed that I think I’ll just grow over and over again. Everything is more fun when you smoke Critical Mass. It’s such a great high, I don’t mind that the grow is a tiny bit technical. I just like having it around. Going to put this one in my regular rotation! Ordered my seeds from Pacific and I was surprised at how fast I got em, and was very pleased with the outcome. Good place to buy!
