Growing notes

Amnesia Z Auto reaches 28–47 inches at harvest — large for an autoflower, so plan vertical space indoors. It performs well in indoor, outdoor, greenhouse, and mixlight setups. The 9–10 week total cycle suits growers fitting multiple runs into a season. Outdoor plants can yield generously when given a warm, sunny spot. Manage plant size early with low-stress training if canopy space is limited.
