Unpopular opinion: I prefer decarbed shatter carts over distillate carts any day of the week. Just enjoy the effects a lot more and I’d rather it have a shatter aftertaste than that weird raw distillate taste.
Just decarb tf out of it then add like 5% terps at the end. Some guys use more but it’ll burn more and it’s probably not good for your lungs to go heavy like that on anything. If you don’t decarb long enough the thing will solidify in there and be unusable so don’t cut that short or you’ll have a bad day. You should prob just make one and see how it holds up after about a week before you go fill a ton of them to make sure your process/ratios are all dialed in. Thing will look perfect right when you make it but if you messed up it’ll cloud up like a week later. Also make sure you’re using legit carts with 2.0mm holes, no less for shatter.
