'Maximum Yield'

A customer has a question and I hope we can get some opinions on it, thanks.

“How much yield can I expect for 6 weeks of veg under prime conditions for Big Bud, Chocolope, and Amnesia Haze? I’d like to know what you personally find an acceptable amount for these strains when you grow. What’s the maximum yield you’ve ever reported and how long were they vegged? I’m wondering what your yields are because you seem to be an experienced grower and if I come up with less yield, I’ll know that I need to improve my grow next time.”

Really comes down to optimal environment
