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, Flavours, 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 flavours 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 flavour 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.

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.
