So I understand the idea of original SOG method Lots of lil plants with main stems. My conclusion, and I hope its right, is that IF I had a 600w HID, I could Put a 4x4 tray down and then I have 16 square feet under the light. So SOG method calls for 2 - 4 little plants per sq ft. So if i had 64 small plants no more nor less than 20 in from the 600w HID light, I could have a harvest of 450 - 650 yield at the end??
