Critical Mass Seeds

The Critical Mass strain is one of the heaviest cannabis strains for production both in & outdoor. With uncompromising medical potency, a pungent fruity aroma, and the largest yields available she is a HUGE addition to any garden.

Critical Mass marijuana is hands down the largest yielding strains currently in production! She has been back crossed to one of our more fragrant and pungent Critical Mass weed phenotypes creating the largest fruitiest Critical Mass plants possible! Her genetic pedigree originating from a particularly heavy Afghani combined with the original Skunk #1. Known to produce kolas so large they literally snap off under their own weight. Her medicinal value and Afghani heritage is evident in her powerfully narcotic effects. So if you demand high yields with an even higher potency Critical Mass Strain is the only choice!

Critical Mass has a very nice plant metabolism and structure, resulting in very frosty and dense buds with a sharp flavor. The Critical Mass strain is a reworked excellent version of an old breed once known as Big Bud. This is a large yielding strain with an equally high stone.

Critical Mass strain flowers fairly quickly at 80 days from seed.

THC levels of this strain may reach up to 24%.

Week 2!! Critical mass is definitely the way to go!!!

Awesome first grow!

I am writing this after having just smoked a bit of this, which was my first grow ever. Bought 3 seeds, all popped. Started off a bit slow but finished on time. I yielded half ounce per plant. Strongest smell I've ever smelt. I'm back for more today.

fast shipped

discrete shipping arrived 6 days 2 of 3 seeds popped and are growing nicely

Looking good - fast growth (indoor)

Germinated day 2, above potting soil with cotyledons on day 4.
Day 31 repotted to fabric and moved under quantum board. Humidity was a little high in tent so the plants produced some massive leaves (hand sized & larger). Plants were about 30" tall in 55 days from start. Will submit an update later.
Vigorous growth - more than anything else in tent. (Cindy 99 started at the same time is a little more compact).
Pictures are numbered with day from start (had more but limited to sharing 5 ;-) )

Still a satisfied customer

The germination was about 70-80 percent for all my orders from seedking. Super easy to grow. I will look forward to my future orders.

So easy to grow! Love seed king

Seed king ships fast. Auto flower so easy it seems like you could toss these in the backyard and come back to perfect ganja in two months

Excellent as always

I tell everyone i know to use Seed King and i think you owe me!
The critical mass is outstanding.. i would go as far as saying it blew my mind!
Growing blue dream next, can't wait!!

Excellent smooth smoke. Great for out door adventure camping and just chilling on the couch

I would recommend this for people in the evening or early in the morning if you want to be stoned most of the day. Great for nausea And anxiety. Really heavy hitting plant. My first time with this strain and I give it 5 stars

First try

First time I tried growing a plant. I started with 1 seed and it seems to be doing good. Here it is at day 87. It is exactly as advertized, thanks so much.

!!! Critical Mass !!!

As always seeds arrived super fast. The seed look amazing, great quality genetics. I'm popping 4 in tonight. I'm so excited to see how big and fast they grow. I'll ad pictures once they pop up.
