The Royal Critical Auto Strain: Perfect for Any Time of Day

Royal Critical Auto boasts rapid flowering times and sizable yields. Her moderate THC content and delicious terpene profile synergise to deliver a joyous and laughter-filled high. Learn more about this popular cultivar below.

Royal Critical Auto Cannabis Seeds: Award-Winning Progeny of Afghan and Skunk

Having won many prestigious awards in Spain, Royal Critical Auto has become one of the most popular autoflower cannabis strains around. As the autoflowering version of the acclaimed Critical, she has an ancestry of Afghan and Skunk genetics. The addition of ruderalis genes ensures compact growth and the autoflower trait, resulting in a fast growing cycle. Overall, this cultivar features 50% indica genetics, 15% sativa, and 35% ruderalis. 

Aromas, Flavors, and Effects of the Royal Critical Auto Strain: Welcome to Euphoria

At first glance, Royal Critical Auto’s THC content of 14% might seem overly mild. However, her effects aren’t rooted in THC alone. The addition of many aromatic terpenes also influences her psychoactive effect. Together, these plant chemicals exert a euphoric and giggly high perfect for social occasions. You’ll feel uplifted, joyous, and filled with laughter without becoming overly stoned. Delightful aromas and flavors of candy, fruit, and pepper round off the experience.

Growing Royal Critical Auto Cannabis Seeds: Fast and Fruitful

Royal Critical Auto cannabis seeds perform best when sown directly into 11-litre pots. Run your lights for 24 hours each day as soon as sprouts emerge from the soil. Within two weeks, your plants will stand at around 20cm and will have developed several sets of luscious true leaves. Move your pots outdoors into a sunny position, or keep them inside under 24 hours of light, or 18 hours on and 6 hours off. Apply LST on the third week of the growing cycle to keep your plant compact yet productive. By the end of veg, your plants will stand at around 60cm in height.

During bloom, plants will peak at around 100cm if trained. Defoliate where necessary, increasing airflow in the canopy and exposing all maturing buds to direct light. Trigger a flush during the final two weeks of cultivation by withholding all nutrients, increasing the flavor and smoothness of your harvest. After a growing cycle of just 10–11 weeks, prepare to pull in up to 400g/m² from indoor plants and 115–165g/plant from those grown outdoors.

    Title : This one is pretty good!
    Comment : Seed actually sprouted! Grew very vigorously and bushy. I'm pleased with this one. Gave many budding sites and high are good as well. Very sleepy weed though. Good for that. Down fall was kind of short only about 1.5 ft. Got about 1 oz. Total out of it.

    Title : TASTY!
    Comment : I have grown quite a few RQS strains the past year and this definitely stood out as far as taste! Definitely full of flavor! May not be the most potent of the next strains mentioned, but its up there with: Mike Tyson Punch Pie, Apple Fritter, and Lemon Shining Silver Haze flavors.

    By D. S. on 18/Sep/2024 :

    Title : Definitely a strong producer
    Comment : Two plants yielded 3.56oz of dried/cured flower. This is amazing, considering that the plants each topped out at about 20" each. Buds were very nicely sized and heavy with trichomes. Produces a really great high, that I will continue to return to.

    Title : Small but Delicious
    Comment : Perfect stealth plant! Super easy, she likes minimal fertilizer and produces loads of oil! Fun plants to grow

    By J. D. on 20/Aug/2024 :

    Title : Quality, uniform auto
    Comment : Only growing for 3 years and 2nd year dabbling in autos. This plant is incredibly stocky, 6 nearly identical branches with golfball-plus sized colas on each branch followed by smaller secondary and tertiary nugs. I used this as a "test" plant and went against the grain by topping it once it had 3 sets of leaves. Glad I did. Once topped she exploded. She's about 3 to 4 weeks from harvest. Main colas and fattening up and coated in dense trichomes. Her smell is earthy and funky. Eager to harvest, dry and cure!

    By M. D. on 31/Jul/2024 :

    Title : Very pretty plant
    Comment : Hearty Dense Nugs, Looking forward to smoking it, All my seeds popped and are growing great!

    By A. S. on 16/May/2024 :

    Title : Nice grower
    Comment : First time growing, put it in soil and it took off fast! Ended up with 66 grams of dry bud with no training or special treatment. Buds have an umami/earthy/black tea smell…. Very nice smoke too!

    By E. G. on 25/Apr/2024 :

    Title : Royal Crit Auto
    Comment : Will concur with someone else’s comment about them being slower than most autos. BUT, with patience comes a great quality or even quantity. I got quality so, with that being said this auto is a great addition to anyone’s grow. Worth the grow especially since you can get it for free when you purchase some friends with it.

There is not a specific pot size per strain.The size of the pot will have an influence on the size of your plants, on yields, and on the frequency you water your plants.
