Its been my experience (and that of others) that these type of lights should do ok at growing plants. IIRC, plants are fairly opportunistic and will use what is available. Sure a tuned spectrum can grow plants better, but we are talking a marginal enhancement, not growing vs not growing. I think that your problem might be more of one of geometry. Can you raise your current lights any to give a better spread?
