Critical+ 2.0 Auto-flowering Review
In-depth review of the strains seeds and plants
The Critical 2.0 AutoFlowering strain of Marijuana is Dinafem’s cross between the infamous Critical+ and the Critical+ Auto-flowering strains. This resulted in a hybrid strain of cannabis with an indica dominance. Rigorous, pretty easy to grow and with a short but productive flowering cycle this seems like a nice little plant to grow indoors, whether you’re a beginner or advanced grower.
Here’s a little picture of 2 of our own plants in the early flowering stage:
As you can see we actually decided to grow this strain within our first batch of auto-flowering seeds which is why we decided to do a guide on this strain.

Origin and History of Critical+ 2.0 Auto-flowering Strain of Marijuana
As we started saying in the introduction of this pice, C+ 2.0 Auto is a cross between the Dinafem Seeds’s Critical+ and the Critical+ Auto-flowering strains of weed which resulted in an hybrid, indica dominance, cannabis strain of good quality (on paper, we’ll let you know what we personally think once that time has come).
This version is the improve strain of its ancestor Critical+ Autoflo, Dinafem’s effort concentrated in improving the yield, resistance to external factors (environment, nutrient deficiencies, ..) and height control. These efforts seem to have shown their fruits since, personally, these are the most resistant plants in the bunch.
Official presentation of Dinafem’s Critical+ 2.0 Auto Seeds
Dinafem generally presents their plants through video and they didn’t miss out for this strain either. Here’s the 3 presentation video’s

| Plant Size | This is an aspect Dinafem worked on. Compared to Critical+, Critical+ 2.0 Auto-flowering will grow short and bushy, enabling its culture in small indoor or outdoor spaces. |
Is Critical+ 2.0 Auto Flowering easy to grow?
In short yes! Dinafem Seeds increased the resistance to heat and nutrient deficiencies, as well as the previous issues with height control, making Critical+ 2.0 Auto-Flowering Seeds a perfect strain to start with if you’re an newbie at indoor growing!
For more advanced growers this strain can also be fun, with the right amounts of stress you’ll be able to grow small, compact but massive plants in a short period in time thanks to its short lifecycle, making this plant a perfect strain to keep around in your arsenal!
You’ll be able to increase your yearly yields nicely.
Does Critical+ 2.0 Auto grow indoor?
With no problem at all! It’s actually more of an indoor strain of cannabis than an outdoor one, although it will strive outdoors also.
Thanks to the improvements made, this strain will resist and grow nice buds in any environment, making it a perfect strain if you have heat issues within your grow room.
Does Critical+ 2.0 Auto grow outdoor?
If you’re an outdoor grower this plant can be grown year round as long as the outdoor temperatures are globally above 16°C. Dinafem advances that this strain will strive even it the harshest weather, but I double that a sprout of this plant will grow in temperatures below 15°C; and even if they do, so much energy will be spent on survival that the buds won’t be all that.

Critical 2.0 Autoflowering review
We’re still currently growing this strain so this section will evolve with time but here’s what we’ve got so far
- Resists well to environment changes: In our grow room we’re constantly fighting heat issues and between the Critical 2.0 and the Fruit strain this one show much less signs of heat stressing.
- Good resistance to nutrient deficiency: All our fruit plants have had nutrient issues, whether its nitrogen deficiency or nutrient burn.
The Critical has been very stable on that aspect. - Low resistance to light burn: She showed some pretty severe issues with light burn, even when the light isn’t that close (I aways keep it at least 20cm away when using the 400W lighting)
- Quick to flower: In less than 3 weeks she had started stretching. Mainly due to errors on our side though. We’ve covered that subject fully in our auto flowering guide if you want to know more.
- Manageable height: As long as the plant has space the stretch isn’t too strong, making the overall height of the plant pretty small which is perfect for indoor growers
