Critical XXL Auto
Critical XXL Auto is one of the most complete autoflowers out there. It has everything a grower could want from a plant: fast growth, a manageable size, huge bud production, loads of resin, an intense citrus and fruity flavor, very powerful effects and a super-short cycle of just 8-9 weeks.
Critical XXL Auto is the super-productive autoflowering version of Critical Mass, the legendary strain from Mr. Nice and one of the most widely grown varieties in history. Growers rate it highly, praise its spectacular results and recommend it without hesitation.
It is a well-balanced indica-dominant hybrid, a Skunk x Afghani cross, and it is famous for delivering on every front.
Today it comes in both feminized and autoflowering versions, and it has served as the base for many newer strains, which inherit a lot of its best traits.
How to grow Critical XXL Auto
It is one of the easiest cannabis plants you can grow. It is tough like few others, grows vigorously in almost any conditions and always leaves the grower happy.
In good conditions it can reach an impressive height of about 5 feet. It is not the smallest or most discreet autoflower, but it is one of the most productive.
It has a very short vegetative phase and starts flowering after just 3-4 weeks. During this stage, avoid transplanting: it stresses the plant, which may stall for a few very precious days.
At Bulk Genetics we recommend starting in a large pot with quality soil from day one. That way the plant can reach its full size before flowering kicks in. All in all, it is ready to harvest about 8-9 weeks from germination, and you can run up to 3 grows back to back between spring and summer.
Characteristics of Critical XXL Auto
This strain produces competition-grade buds: big, rock-hard and very resinous. In humid environments you will need good ventilation to avoid mold problems.
Its aroma and flavor stay true to its Critical mother, with a clear citrus, fruity and skunky touch over a piney background. Skunk hybrids are also famous for their strong smell, so indoors a good odor-control setup is a smart idea.
The effects are very powerful. It kicks off with a strongly psychoactive high inherited from its sativa genes, but the feeling soon turns deeply relaxing and peaceful. It is a perfect strain for the end of the day.
Yields are very high: up to 7 oz outdoors on the largest plants. Indoors, with 300-350 W of LED lighting, you can reach 1.8 oz per sq ft.
