This weeks blog shows Seedstockers customers ‘Tony21’ grow 5 huge BCN Critical XXL Autoflower plants in auto pots of coco fibre with LED grow lights.

The original grow diary is here on the Autoflower Network.
See more about BCN Critical XXL Autoflower growing.
BCN Critical XXL Autoflower is bred from a very special Critical mother plant.
Like many other Critical plants, THC levels were well over 20%. But the mother plant used to produce BCN Critical XXL was the best yielding plant from several hundred that were grown from seed with unique levels of bud and resin production.
These XXL yielding varieties depend entirely on high quality selective breeding and are the result of months of hard work growing out hundreds of plants in the search for exceptional parent plants.
The result is BCN Critical XXL Autoflower, she grows from seed to harvest in around 75 days and grows well in any grow medium.
In this weeks pictures you can see the remarkable size of the buds and blooms. Often the plants will need supporting to prevent them collapsing under the weight of their own buds, especially during the last 2 weeks before harvest when the branches are under maximum strain.
BCN Critical XXL Autoflower seeds will grow well under 20 hours of daily light with 4 hours of darkness, though some Seedstocker customers grown them under 24 hour light from start to finish.
The plants grow with vigor and speed, often reaching over a metre tall especially in optimised conditions.
BCN Critical XXL Autoflower thrives in high intensity light conditions.
In this weeks grow she was cultivated under high power LED grow lights with over 500W of actual power draw. Autos grow well under LED light, the optimised light spectrum allows rapid growth and the reduced heat levels allows the cannabis plants to grow with less heat stress.
Auto pots are gravity fed automatic feeding systems. They are useful for the indoor cannabis grower looking for an easy, maintenance free way to feed the plants. When the auto pot system senses that the plant water levels need topping up more feed solution is released from the central reservoir.
Its a simple and proven system used by many grower.
In this weeks grow Tony21 combined the autopot system with coco fibre.
Coco fibre allows great levels of root aeration, meaning that the roots are able to enjoy high oxygen levels thanks to the light and porous coco fibre. This means that the marijuana plants will grow faster than they generally would in soil.
The only disadvantage of growing in coco compared to soil is that, unlike soil, the coco fibre contains no nutrients. When growing in coco fibre you need to control and add all your nutrients. When growing in soil, the soil itself contains many minerals and nutrients.
The combination of coco fibre and auto pots provided a great growing environment for the BCN Critical XXL Autoflower, they grew rapidly reaching a metre tall in around 7 weeks before filling out with exceptional levels of bud production.
BCN Critical XXL Autoflower is quickly gaining a reputation as one of the best yielding modern autoflowering cannabis varieties. Its an easy variety to grow, robust enough to grow with equal vigor in any grow system.
She also grows well outdoors taking around 95 days from seed to harvest, like many of the best feminized auto flowers she has the genetic heritage to perform well under a wide range of growing conditions.
But best of all, BCN Critical XXL Autoflower produces exceptionally heavy crops of THC rich cannabis quickly and easily.
Simply combine these genetics with a good grow room, with high light levels and grow one of your easiest XXL harvests.
