pretending that you’ll capture 75% of the available cannabinoids in your input biomass by the time you get to distillate is not an unreasonable starting point for your ROI math.
Figure you might start out closer to 65-70% efficiency, and target 80% as your long term goal.
You’ll want In House analytics early rather than late if you want to dial your process in and actually make that return on your investment.
Edit: for anyone who’s actually paying attention. stop calculating yield based on input biomass weight. 10-20% yields? how is that useful to you? base your yields on actual percent of input cannabinoids in your output. yeah, it requires knowing the potency of your input. you don’t do that? how do you know what you’re throwing away?!?
