Check the bulbs. Even if the bulbs still light (haven’t burnt out), if the ends of the tubes are dark they should be replaced. An old bulb’s light may be as little as half the strength of a new bulb.
Clean the bulbs. Wipe them down with a damp cloth (make sure the unit is unplugged) or a dry duster to remove dust and grime that would otherwise diminish the light. Remember to do this once a week while your seeds grow.
