Welcome to the forum. You can switch them whenever you want to fit your growing space height. They will double or maybe triple in size after starting flowering. if you want to presex them you would have to leave then in vegging until they reach alternating nodes, rather than opposite nodes, usually around 8 to 10 nodes. Earl has a thread posted here on presexing. VV
