Hey guys. I'm having issues with stretching, so I want to try some subcanopy lighting. My one question is this, since I'm running a 600w hortilux as the primary light (4th week of flower), should the subcanopy light be blue or red. I know blue makes for more compact plants in veg but I know red is best for flowering and I'm not sure which one would be best. Thanks!
