I have a Width 7'9'', Lenght 4'5'' and Height 7'11'' Space with a 1000 MH/HPS and was wondering how tall can I get my vegging plants before switching to 12/12 flower? I really want max yield appropriate for my space... with 6 plants they are all Barneys Farm:2 Pineapple Chunk, 2 Liberty Haze and 2 Critical Kush. Everywhere people tell me different results some people say an oz a plant but I know if I continue vegging, it will double to triple my final yield correct? so how tall (inches wise) before switching? The guy at my hydro store said not to exceed 26 inches or they will get out of hand.. I have not started as I am waiting for the seeds but I plan on super-cropping/mainlining methods
