Critical Thunder Auto has a strong potency for an autoflowing strain thanks to its incredible genetics. And even with its Indica dominance, the effects are still balanced enough to deliver a well-rounded, comprehensive stone. It has a very definitive taste of skunk, citrus limes, and a little bit of sweet spiciness. Although this is not necessarily the easiest to grow, it yields large harvests of amazing buds.

Strain Traits


To create Critical Thunder Auto we took yield and strength to the limit by crossing two of our biggest and most potent strains available, Critical Mass and White Widow Max Auto. Together this cross created an Indica-dominant strain with a strong potency that delivers a powerful high with a nice balance of cerebral and body effects. 


This strain produces THC levels that range from 15 to 18%. For an auto-flowering plant, these levels are extremely high. Its genetics provide a fast-acting and hard-hitting buzz with medicinal type qualities that can settle in and stay put for hours. These effects are cerebral, creative, happy, but also very calming and deeply relaxing. It all depends on how much you smoke because the more hits your take the more sedative the effects become which can lead to couch-lock.   


Yields are massive for this auto strain, easily coming in around 80 grams per plant or 300 grams per M2. Flowering time isn't as fast as other auto-flowering strains, but if you let them flower for 9 to 10 weeks, the buds will become dense and resinous helping to maximize yields. This strain does well using a SOG setup, but can also grow outdoors if you have an area to do so. With the short life cycle, you may get two harvests during the year, one occurring around July/Augst and the other in September/October. Lastly, the heights stay fairly short only reaching 60 cm tall through to a maximum of 100 cm.  

Appearance & Aroma

The Indica dominance means this plant grows short and bushy and develops large single colas with lots of side branches and numerous buds. Also, these dense buds grow lots of orangish-brown hairs and are covered in sugary crystals. 

 The smell they produce is a combination of skunk and citrus fruit that overwhelms the space where you’re growing these plants. Although they give off a strong aroma, it’s a pleasant smell that’s invigorating and prepares you for a taste experience that’s hard to match. 


MSNL Editors Verdict

Critical Thunder Auto is the powerful, big yielding, auto-flowering strain specifically bred by our breeders for the Indica lovers out there. The stone is a strong one because of its “White” genetics. It instantly sets in at the back of your head and it rapidly spreads down into the extremities to give you a deep, full-body relief and relaxation.

Tasting Notes

An acidic sharpness of lemon and lime come through with the very first inhale. Because it can have a tickly feeling on your throat, it may cause you to cough if you try and smoke too much at once. There are also undeniable flavours skunk and spice that appear with each exhale.
