The plant will reveg. The buds will die, and the plant will stunt growth. Then when you try to reflower, it will take longer, and have a hightened probability of exhibiting hermaphrodite traits. Dont do it. DO what MaryjaneMenehune said, and try to increase the intensity of the lights when they ARE on. You can also increase bud size/density and THC % (potency) by decreasing humidity and adding Ultraviolet light (UVB only).

That is the short answer.

Oh and make sure you let them mature properly. Be patient.

Be cool...like the wind.
