Hempy Yield, Looking For The Facts

[Concept]

So I've been reading a lot about hempy grows and it has caught my eye. My issue is that my findings on average yield are kinda all over the place. So figured I'd just make a post and ask for an experienced hempy grower's advice. So if you know hempy decently well under the following parameters what kind of yield could one approximate per 2L bottle.

Light: 600w HID
Hempy Style: 80% perlite 20% vermiculite
Size: 2L Bottles , in 4x4 tent
Nutrients: Sensi Grow/Bloom by Advanced Nutrients
Veg Time: Preferably >1 week
Temps: 77-80
With good airflow and corrected PH
