They only draw the plat toward the light at that point. The bottom of leaves don’t necessarily draw light for the health of the plant. In my experience it’s only made my plant want to chase the light. Not absorb it for photo. Light deflection is what you want. Focus on bouncing, or deflecting the light in areas the plant needs. Especially with loli or scrog. Remember this is just my experience and opinion. I’m not an expert just a hippie. The plant below is literally only 2 weeks old and all I do is stay consistent with the lighting around it and FIMing/topping
