I was just reading up on this
Indoor Marijuana Horticulture
By Jorge Cervantes
"Mother plants must have 18 hrs a day to retain a strong and accurate set of genetics.
Each time a mother is forced from vegetative growth into flowering, and back to vegetative growth her genetic integrity diminishes..."
"Mothers that are forced to flower and then revert back to vegetative growth, not only yield less, they are stressed and confused."
Now what if this practice of revegging, becomes common place, and the degraded genetics are then used to create seed? The entire gene pool is polluted.
