Just a thought - If you want to keep growing bigger sized plants, look into adding some side lighting provided you are able to cool it. I actually get more canopy out of my flowering rooms by having aisles to walk through and using the "side canopy" with trellis and side lighting. I get nice colas on the sides and the tops this way. Overall the room yields better this way than if I packed it with plants and had to crawl under them to water. You might look at my grow journal to see if you get any ideas for your setup.
A SoG has the benefit of little to no veg, but you need a LOT more plants. I used to run SoG before I had a legit plant count. I learned to grow them big because of a plant count. Now I get more out of a room because of it. I do have to veg a while but I do that in my veg room under less lighting while other plants are flowering.
