MAC 1 Auto is appreciated for its striking resin production, balanced growth, and creamy-citrus aroma in a fast autoflower format.

Light defoliation is okay early in flower, but avoid heavy pruning due to its quick life cycle.

It builds gradually, becoming noticeable by week 5 — carbon filters are helpful for indoor odor control.
