Critical, The best cannabis strain for commercial growers.

As far as Royal Queen Seeds products go, Royal Critical is quite possibly the most bang for your buck we offer.

As far as Royal Queen Seeds products go, Royal Critical is quite possibly the most bang for your buck we offer. By crossing an Afghani strain and a Skunk variety, we’ve created a potent indica-dominant cash crop that is great for any large-scale grower.


Gram for gram, Critical is one of the top-yielding strains of all time―a trait owed to its Skunk #1 and Afghani heritage. Also going by the title of Critical Mass, when you see it in full bloom, it’s not hard to see why growers the world over use Critical as a cash crop. Its genetics are not only the basis for its industry-leading performance, but have been used to create countless hybrids, all hoping to replicate the efficacy of the Critical bloodline.

Critical is an indica-dominant strain (60%), inheriting a short flowering period and an unassuming stature (80–140cm). The strain is famously easy to grow, produces a pleasant, relaxing high, and yields large enough to make your eyes water with anticipation. By selecting the best phenotypes, Critical’s original creators have guaranteed that it will be a mainstay in any grower’s arsenal for years to come.

Now, thanks to the breeding prowess of RQS, the tried and tested Critical genetics have been refined even further with Royal Critical. Retaining all of the attributes Critical strains are revered for, she is so simple to grow that all that stands between you and over 600 grams per plant is the “add to cart” button.

Such bountiful yields would be worthless without an equally impressive flavour and aroma―thankfully, Royal Critical delivers on both fronts. As Royal Critical takes shape, the first thing that hits you is her aroma. Earthy and pungent, with a hint of citrus, her scent quickly fills an indoor grow room, teasing at the motherload of buds you can expect during the flowering stage.

Once harvested and cured, the earthy flavours remain, but piney undertones and a touch of sweetness linger with every toke. The Afghani heritage shines through in Royal Critical’s taste, delivering a classic but never underwhelming experience. Cannabis connoisseur or complete newbie, the flavour perfectly encapsulates the phrase “dank weed”―you won’t be disappointed.


Our feminized Royal Critical seeds come prepared to flower quicker than most other varieties. With only 7–8 weeks of bloom, these plants have a much faster turnover than other cash crops. This makes them more efficient for growers in climates typically attuned to growth, such as California, Italy, and Spain. It also, however, opens up the possibility for growth in more northern climates, as plants can be harvested earlier in the year—before the cold and rainy seasons set in for many regions.

Thanks to short internodes that become abundantly filled with buds as growth continues, these plants produce generous amounts of product each season. As far as yield goes, you’ll be hard pressed to find a crop that brings in more volume in 7 weeks than this specimen. Grown outdoors, each plant can reach a height of 220cm and produce up to 650g/plant.

The plants also do quite well indoors when grown under the right conditions. With a 600W lamp, plants can easily grow to 140cm and yield upwards of 550–600g/m². Because of the genetic cross we’ve created with our Skunk, these plants are sturdy enough to go through some weathering outside, and resilient enough to adapt to indoor growth, while still producing ample harvests in both settings.


After falling in love with Royal Critical genetics, our breeders couldn’t pass up the opportunity to create an autoflowering version of the strain. By crossing her with a prime ruderalis specimen, they took her best traits and made her much easier to grow and faster to flower.

Following several generations of breeding, stabilisation, and perfecting these genetics, Royal Critical Automatic emerged with a genetic profile that’s 50% indica, 15% sativa, and 35% ruderalis. After sampling her flowers, effects, and complex terpene profile, RQS breeders released her to the world.

Royal Critical Automatic produces relatively large and tapered flowers that display brilliant white trichomes and deep red orange against a dark green canvas. This hardy strain grows comfortably in a wide range of environments but will perform best in a mild climate.

Indoor plants grow to a small and easily manageable height of 55-65cm. Such a small stature makes them ideal for cultivating in small boxes, buckets, and cupboards. Cultivators looking to maintain privacy throughout the grow cycle will feel confident with such tamed plants. Use smaller pots and low-stress training to keep her at the lower end of the height spectrum.

Her resinous flowers produce THC levels of 14% and a sweet and spicy terpene profile. Expect a mellow and stoning high that primarily targets the body and melts the muscles. Her relaxing effects are ideal for the evenings, especially when you don’t feel like getting too blasted.

Our feminized Critical seeds come prepared to flower earlier than most other varieties. With only 7-8 weeks until they finished flowering, these plants have a shorter flowering period than other cash crop varieties
