Hey buddy,For me,Distance of light depends on how your plant feels.First one,If your plant is stretching, lower your light.Another one, Put your palm on top of the plant and if your palm feels hot or warm,your plant feels the same.Means they are in heat stress. It will be followed by Curling leaves, Then raise your light alittle bit until your palm feels neither hot nor warm.I would start with 24inches distance.Happy growing... ✌️
