Yea, man. Basically what invision said. 2.5 feet is crazy far. You should be able to get your 600w within 1 foot or even up to 6-8 inches away if you cool the lamp correctly. I've had mine as close as 2-3 inches with a 400w COOLTUBE design.

The lumens decrease exponentially with each inch you move away. Fewer lumens = smaller, less dense buds...and visa versa.

NICE plants ya got there, though Just A Beginner! :greenthumb:
