T5 ho fixture for side lighting

Anyone add suplimental lighting as side or under canopy extra to help lowers get light? I've reached the limit of training and these plants are a few weeks from harvest apart from heat control and having to rotate the plants is this a good idea or just a waste of power?

It's probally a negligible amount especially from t5ho. Past 6 inches there intensity GREATLY drops off.. also the have like 0 penetration I used to think hanging individual squiggly throughout the grow wouldabeen a good idea but ..waste of time and effort and money imo

Thanks I though as much
