I have a question about supplemental lighting using the standard e27 style led bulbs. Say hypothetically I have a 300w led... could I add some of these led bulbs (say 54w in red and blue spectrum, 3w x 18 diodes) for flower? would it make a difference and is it a good idea? Also, some of the bulbs I see at this wattage are 38 PAR rating. does anyone know the PAR of some of the popular led lights for comparison?
