Side lighting / up lighting questions?

My grow area is 4x4x8. Im using a 400w hps plus 4 150w cfls. Had the cfls just pointing down toward canopy. Im interested in using the cfls as side or up lighting any suggestions on placement. Thanks in advance for any info

Place them where you need light enhancement. Use your 400w on top, and place the 4 cfl’s anywhere you need light.
