Distance and spacing of LED growlights for propagation

I am planning to make an indoor propagation setup which consists of h:30cm x w:40 x L:50cm recycled polystyrene boxes and full spectrum LED panels. Clearly, the biggest limitation is height in this case. I might join two boxes to double the height,…
