ya either bored and posting for the fun of it or lazy and can't be arsed reading. veg under horizontal light and make em stretch then switch to vert when ya ready.
Get the small wire racks on sale at home depot , believe theres 3 shelfs,can be put on wheels and make a octagon or close to that ... Hang bulb and raise and lower to spread coverage every day or so.
Good luck
I say the first week and a half vegging horizontally is fine but by then you should veg vertically so the structure is stronger and use to the vertical grow style once the buds start packing on
