i think gravity does play a role. when you plant a seed the root grows downward and pushed the stem upward so they must be using gravity to know which way is "outside" so it can make the stem go outside.
no offense but i think its stupid and too much trouble growing sideways you will only have light pointing from the side no light gets into the lower canopy and also even if the plant is sideways the roots will grow downward so the best thing to do is plant normal but train it to be sideways

but still if you make it normal you add light in the sides and make ur plant go wild and big.. this wouldnt make plants big and im sure you will give up after 2 weeks seing that the plant doesnt grow like you though it would
