Recently, I put 6 plants under a MH for 3 weeks of flower. The other day I switched the bulb to a HPS. What I would like to know is there really a difference between flowering under a MH and flowering under a HPS? I guess this is a question for someone who has done both. What kind of traits did you recieve from each one? Is switching from a MH to an HPS going to produce more even since they were flowering under a MH for 3 weeks? I just want to hear peoples experiences with each light. Thanks a lot guys!
