Appearance of the plant

When growing, Fast Buds 420’s Critical Auto plants reach heights ranging from 90 to 140cm, meaning growers with limited vertical space may have problems.

Auto Critical grows with a short, compact internodal space and dense buds will sprout on each internode, making her a high yielding variety (450-600gr / m2) that may require support during flowering.

Outdoors, this plant performs incredibly well and especially in a Mediterranean climate, where it will grow in the shape of a Christmas tree that is filled with chunky buds covered with a trichome glaze in each branch.

Growth tips

Critical Auto by Fast Buds 420 can be harvested several times a year outdoors and does not require a lot of maintenance. Since Original Auto Critical is a strain known for its large yields, it is recommended to use bamboo cane or a side support to support the weight of the buds from the start of flowering.

LST with this strain in the early stages of growth will increase the number of flowering sites, further improving production! Due to its large size, folding the plant is especially important in cases where space is limited.
