Hey lighting, I know it sounds like I'm picking on you, but I assure you I'm not.
But if you are insinuating that diffused reflection on a flat footprint is more efficient than a 360 degree light source utilizing increased square footage, you are grossly mistaken. On average, a properly designed vertical sog will produce approximately 2.3 x the grow area of your flat surface. While it is true that the grow area of a vertical setup will decrease as plants grow, there are a few methods that compensate for this. My system allows me to expand my grow area as the plants mature and get closer to the light, it may not be the best, but it's pretty damn efficient.
I've been growing for years my friend, and my ego will never get in the way of me learning things, I've came across some awesome ideas from growers with far less experience.
In reality, it all boils down to the quality of your product and the amount of time and money spent from start to finish.
I looked at the pics of your scrog and admit it looks great, but you are not going to match the efficiency of a well designed vertical grow with the program you're running, it just isn't going to happen.
And I have to tell you, I find it quite ironic for you to accuse guys in here of exaggerating their yields, while you're posting some pretty thick claims yourself.
