I don't understand your post, as you state t5 didn't 'fix' it and then explain why t5 can compensate (aka fix) shading from a single point light source.
Anyways, shading from a singular light source (such as led) causes euphylia to grow this way. 'Fixing' it can be accomplished by adding multiple point light sources.
exactly. It’s not the t5 it’s adding more light so it doesn’t shade. T5’s have shade too. Adding another led Or any light will reduce shading.
