Light Poisoning

What Does Light Poisoning Mean?

Light poisoning is method of cannabis cultivation performed by intentionally interrupting the period of darkness during the flowering cycle. This practice is typically performed for the first three weeks of flowering.

Light poisoning can cause a plant to become hermaphroditic. This will result in self-pollination and can result in the pollination of surrounding plants as well. Some growers contend that this produces all female seed; other growers claim that any seed produced by this method will lead to hermaphroditic plants as well.

Maximum Yield Explains Light Poisoning

Though there are variations in practice, in general light poisoning is done by reintroducing light for a period of up to one hour half way through what would be a twelve hour period of darkness.

This means that a plant would get the normal 12 hours of light, then five and one-half hours of dark. It would then get light for one hour and then another five and one-half hours of dark before its next 12-hour light cycle.

The term light poisoning causes much confusion. Some growers believe this term refers to any unwanted light or unintentional interruption of a grow. Others believe it refers to light being too close to their plants.
