So colosseum style would yield more than vertical scrogs and sogs?
Thanks hammer thats good to know because I'm still thinking wether or not to switch over to vertical.Just0 using Vertical lights gave me a big improvement over using hoods.. I changed to vertical last year. I have seen much better coverage and yield improvements.
