He’s messing with you due to current events.
In all seriousness, id the d6 the dude is trying to sell you is actually d10 like these guys say, you probably don’t want it. I’m assuming you are making recreational carts. You are a good sport, so I’ll expand
Live resin: 100% (Absolute highest quality you can produce with minimal effort)
HTE: 10-50% total, depending on how crystallized the hte is
Hemp terps: 7-10%
If anyone who has tried @Betroit terps please chime in on your favorite ratio, it seems you guys use less than 10%
If you are using a plastic bodied cartridge, and need to keep your terps under 8%, you can either increase distillate or add c8 if your material is too thicc (vacuum cooked diamonds mmmmmm)
