I know another one of these threads. Just looking for input or suggestions. I've done my research according to Hoppy's thread a dual t8 fixture can get 50-60 par at 20 inches which is the same as most of the t5ho fixtures at this distance. Is this accurate? If so I see no reason to spend $10 a bulb every year if I can just pay $8 a year for two daylight t8 bulbs.
