Growing Critical Auto (indoor and outdoor)

She is an easy-to-grow autoflowering variety, a cross of Ruderalis, Indica, and Sativa strains. This extraordinary mix produces a vigorous plant with large, dense buds and a heavy Indica effect of the Critical.

Although she is relatively small and stocky, her structure is open, allowing light to reach the entire plant and yields larger and better quality.

Critical Auto does not require much fertilization or extensive care, so it is perfect for inexperienced cannabis growers. It is a very generous plant that grows with strength and remains healthy without requiring special attention.

An increase in soil fertility with a 30% contribution of coconut fibers will be greatly appreciated by this strain which is genetically programmed to start flowering automatically, regardless of light conditions.

Flowering time

Critical Autoflower is a fast grower and completes its entire flowering phase in just 56 to 63 days.

Plant height

The feminized Critical Autoflower strain seeds grow into beautiful, vigorous plants that can reach just over a meter in height when grown outdoors. Her branches extend both vertically and horizontally, and its few leaves allow good aeration and light penetration, ideal for producing large, beautiful buds. In addition, indoor growers will find the strain easy to manage, as typical indoor heights are only 55 to 65 cm.

Critical Autoflower yield

The plant produces good yields! Large, dense buds with a sweet, skunk aroma can reach up to 400 to 450 grams per m² indoors and up to 70 to 200 grams per plant outdoors.


Critical Autoflower's high is more bodily than cerebral and provides tremendous muscle relaxation. Often consumed for therapeutic purposes, Auto Critical is an excellent asset in the fight against insomnia, but it is absolutely also ideal for providing a good moment of relaxation. The weed also features a euphoric effect in small doses, while high doses generate complete peace and even some fatigue.

In terms of medical potential, Critical Autoflower is perfect for helping to treat a wide range of conditions, including chronic pain, sleep disturbances, stress, anxiety, muscle spasms, and a host of physical ailments.

Side effects

Critical Autoflower is a well-balanced strain that results in a nice, smooth smoke. In addition, this strain is not associated with any unpleasant side effects other than the ubiquitous dry eyes and cottonmouth.

Smell and taste

Critical Autoflower has an enticing aroma made up of lemony fruit scents. Its flavor is equally delicious: sweet, and woody aromas that linger in the mouth.


Critical Autoflower is a cannabis strain resulting from a mix between Critical and Lowryder, one of the most renowned Ruderalis varieties. This strain is ideal for inexperienced growers who would like to take it easy at first before embarking on the more complex mysteries of cannabis cultivation.

Excellent strain, excellent yield, excellent buds, excellent smell, excellent taste, fast flowering time. My favourite autoflower strain so far. And yes it was 6/6 all nice and smooth. Little maintenance, easy to grow. I recommend this strain to everyone! Big thumbs up WSE!

Hi Hitman, Thanks for this excellent review! Enjoy your buds! Cheers, Ian

Scott (Verified customer) 2021-12-29

Couldn't be happier with my purchase. Was a bit worried as I had never purchased seeds online, but delivery came in under a week, no problems whatsoever. I'm a beginner gardener, however you'd think I'd done this before with the way these girls are going. Germinated within 2 days and super healthy 4 week old plants in! Thanks guys, couldn't recommend you more.

Great quality seeds, getting 1lb per plant. Absolutely vigorous growth, lends itself to tipping, low and high stress training. Have WSD got any critical x GG4?

Shipment came faster than expected, planted 12 seed all germinated within a 3 days, quite pleased with strain. Well done guys,

Aaron W (Verified customer) 2021-01-09

First 2 orders never showed ! Mainly due to COVID most likely. The guys reshipped using a different method and even though it would have cost them money they still were true to their word and I received my seeds. Well done to these guys I can’t praise them enough your customer service is outstanding!! 10 out of 10

Juan Vargas (Verified customer) 2020-12-10

I still haven't resived my order, but the customer service has been fantastic. My first order didn't arrive so they sent me another order of seeds for free!

Timothy M. Bambulas (Verified customer) 2020-10-22

Germinated 1st seed in soil and plant never sprouted. 2nd seed germinated in wet paper towels in 2 days then into soil and currently at about 5 inches tall at week 2 and using fox farms nutrients. Shipping took a while due to covid and customs but it was to be expected. Thanks again.

Ariel D. (Verified customer) 2020-05-29

First time grower. after failing with my grows for 10+ times (learning curve with different species and techniques) the Critical Auto flower made it to the end on hydro DWC and the result is Amazing. I’m in love 😍

Madeleine Rogers (Verified customer) 2019-11-02

So far so good, had some trouble with the seeds not sprouting though!

VillaMunson (Verified customer) 2019-08-28

My grow in short: * Seeds arrived within 13 business days * Out of 10 ordered seeds (received 11 seeds) 9 germinated * Grown outdoors in spain * Plants started flowering after 3-4 weeks * Ready to be harvest after a little longer then 3 months (counted from seed to harvest) * Currently stoned every single day lol

sdawg1113 (Verified customer) 2019-08-12

While Ill give the one star for the speedy shipping (5 days), I'm still left feeling wronged since none of the seeds have successfully germinated.

John (Verified customer) 2019-04-10

I got great yield from the Critical autos. the plants actually really looks like the picture here. Thank for the free replacement of the order after the first one didn't arrive. It is pretty nice to have a stable and friendly seedbank delivering what they say, pretty unique these days. I sent some pictures by mail David.

Ervin M. (Verified customer) 2019-03-27
