Wandered through some of the required math here.
Once upon a time. Numbers game: is your WFE a goer?
As for CBG, I’m going to repeat
And point you at: Panakeia and other Hemp Varieties
Your extraction efficiency is also likely to be lower for CBG, but you can probably crash more of it (based on data posted by @Dr_Jebril iirc).
Exactly how those two balance each other will depend on your solvent choice and extraction temperature/technique…
