DrFever Reviewed by DrFever on . Lights off before harvest?? Im harvesting saturday and am wondering if I should shut my lights off for 24 hours or more before harvest. I heard that with the lights off for extra long the plants sugar production will go into overdrive thus producing more crystals. Thanks Rating: 5
