This thread caught my eye because I’ve been curious about making Green Dragon with some of the THC vape carts I have lying around. Thanks for the advice on decarbing – I didn’t know shatter needed that extra step! I’ve tried using regular weed cart in the past, but didn’t think to check if they had any added terpenes or cutting agents. My first attempt tasted rough, like you said, and it was way too harsh. I’ll definitely give it another go with your tip about Everclear and reducing the alcohol in a double boiler (and yeah, that ventilation warning is key, haha).
