I've got the Omega infinity pro 2.7 200w and struggling with what percentage to use it at and to what height...for only 2 auto's just now and it's my first time ever trying it..but loving the journey... hopefully some advice would be great..I know their stunted(that's what i think) sure I'll be told...any good advice on what you see here...seemed to have hit a road block with them... but im trying my best with what I know..
