Do you want cook times or test results?

That person decarbs longer than me but takes it out of the water immediately. I go an extra two steps and make “green dragon” the hot way, and then I cook off the alcohol because it tastes fucking disgusting if you’re takin it straight out of an oral syringe. If it tastes bitter it wasn’t made right, it shouldn’t taste like anything really, nutty and slightly unpleasant, and it should be “liquid” at room temp. It could be thicker or thinner batch to batch, depends on the material.
If you blitz up your material too much, you’ll end up with a small part of the batch that looks gloppy, and that will turn into a hardening epoxy consistency at room temp. It’s because it has tiny particulates of plant matter in it that weren’t filtered off before cooking the alcohol off.
I use a joule sous vide, it works great.
Anyway, you can stop at green dragon if you don’t mind alcohol tinctures.
I make about 100ml of oil per batch. Quality and resin content of the raw material is extremely important. I make a batch only as needed, and keep the “weed flour” ready to go in the freezer and make it about a week before she runs out.
We don’t spray anything on our flowering plants or on our veg plants. I wouldn’t use anything I got from someone else to make it unless I know how they operate and know that they also spray nothing on them, not even neem. The dispos here like to use a bunch of fucking essential oils and shit to spray their plants which I don’t want to then concentrate and ingest.
