i agree as well. its simple (if height is an issue) just run your lights 24/0 for the first two wks (to keep the nodes close as possible) then flip to 12/12.
most people go 12/12 from seed and wonder why their plants stretch so much (especially when height is a concern) people tend to forget a plant can not flower immediately from seed. it must veg for a min of 1.5-2wks on avg (some take longer)
