For anyone else wanting to make some vape this is how I did it:
My VG extract method:
Using 20 grams of trim or around 15 grams of bud.
Put it on a baking tray, bud grounded up & cover with a baking bag. Preheat oven to 220F (about 105c) and cook for 90-mins.
Put VG 300ML into a measuring jug and put the bud in. (Make sure you buy good quality VG!) I got mine from amazon.
Blend it with a electric hand blender until very well mixed in together.
Pour the mix into a mason jar and seal the lid tightly!
Turn crockpot on low heat setting and let it heat up for around half hour. Then Fill crockpot with warm water till half way full.
Put mason jar with lid tightly fitted into baking bag and then into the preheated crockpot.
Keep it on low heat setting for around 30-mins and keep turning it.
At end take out and give jar a good shake.
Turn crockpot onto the "warm" setting and put jar back in.
Leave in for 12-hours, turn it occasionally if possible. (I used a timer on crockpot for this.).
When done remove jar and let it sit for an hour.
Get your now clean measuring jug again and put cheese cloth on the top (secure with rubber band).
Pour mixture into it, and you'll see it starts to drain into the jug.
You should hopefully get around 200ml back of the original 300ml.
Put rubber gloves on and give cheese cloth a good squeeze to get all the remaining mixture out.
Now your ready to get your bottles. Ideally 30ML and glass is better but plastic is ok too.
If you want each bottle to be around 600MG strength then you want to put 10ML of the mixture into each bottle.
If your vaping it I recommend putting an additional 10ML of PG into it as this will thin it out more making it easier to vape. (Shake well once added PG)
If taking it orally just out another 10ML of fresh VG into it.
This will give you 20ML in each bottle at around 600MG strength.
You can then add more of the extract VG if you want to make it stronger after sampling it.
