Breeder – Garden of Green

Critical XXL Cannabis Strain

The fem seeds Critical XXL are the fruit of extensive genetic work done by Irish Seed Bank using Critical Mass genetics, which is famous for its extremely high levels of both output and potency.  In order to create it, we first mixed the Kritikal Bilbo with a copy of Critical + that originated in the woodlands of the Basque Country. 

Then we crossed the resulting hybrid with an authentic Critical Mass. The result is a breed that exhibits responses to all of the features inherited from its ancestors’ genetics, including high THC content and tremendous yields while maintaining the lowest possible cost. This genetics exhibits a profile of exceptionally potent cannabinoids, reaching between 23 and 26% of the psychoactive compound THC. It has an effect that is complementary to both the brain and the body.

Growing Critical XXL Seeds

Critical XXL seeds germinate into plants that are of a manageable size, require little in the way of maintenance, and are well suited to their natural surroundings. It is a strain that has been successfully stabilized, and at the end of the flowering stage, it produces a large quantity of intensely fragrant flowers.

The flowering process is finished in around eight weeks when it is grown indoors. Outside, there is no sign of how long it can take, but considering how quickly it matures, it is reasonable to expect it to be ready for picking somewhat around the end of the summer.

Critical XXL super strain produces exceptionally high yields.  It can achieve 600 grams/m2 when grown inside, and it can reach 1000 grams per plant when grown outdoors.

Critical XXL Weed Taste & Smell

The aroma of Critical XXL is instantly recognizable as being invigorating. This sugary bud has an aroma reminiscent of citrus and sugar and has the power to permeate an entire room with it. This gives you the feeling of being invited and energized. It has a little skunky undertone, along with the aroma of honey that has just been collected, which is delicious.

This aromatic plant offers a flavor that is within expectations. Critical XXL is renowned for having all the delightful flavors that come to mind. When you inhale it, it will produce a taste on your tongue similar to skunky citrus, and when you exhale it, it will remind you of sweet and earthy smoke.

Critical XXL Marijuana Effect  

You can count on Critical Mass to help you unwind and enjoy your time at home, whether you’re planning on spending the evening alone or with friends. This stress puts a significant amount of strain on the body, but as far as you are not required to operate any heavy equipment, you should enjoy a smooth trip.

Critical Mass has the potential to cause drowsiness, & if you continue to consume it in high quantities, don’t be shocked if it ultimately causes you to fall asleep. It is believed that the effects of Critical XXL potent body high can persist for many hours, during which users report feeling giddy and euphoric even after the effect has worn off. Because it is able to keep you in a good mood and will make you feel uplifted, this hybrid is especially nice for those who require a little mood booster.
