Critical Auto is a high-yielding strain with good resistance to mould, pests and plant diseases. It makes a good novice grower's strain.

Indoors it grows to a height of 55 - 65 cm. taking 68 - 72 days to complete its life-cycle and yielding 400 gr/m2 if given 18/20 hours of light per 24. Outdoors it grows taller, 60 - 90 cm, yielding 190 gr/plant.
Critical Auto's dense buds have a strong Skunk scent and it is therefore recommended to use carbon-filters to get rid of the smell if growing indoors near to neighbours. Its taste is sweet, earthy citrus. THC production is 12.5% with 0.5% CBD. The effect is initially stimulating but evolves into a more relaxing high.
