What trappy said is spot on. When I first did it I was impatient so make sure you warm the distillate enough or you could end up in a sticky and stringy mess. Have some iso on hand to clean up with too. I wanted stealth so only added strawberry terps but it worked well.

The ideal ratio of terpenes to distillate depends on your specific preferences. Start with a low ratio, such as 1-5%, and gradually increase it until you achieve the desired flavor and aroma. For example, if you have 10 grams of distillate, you can start with 0.5 grams of terpenes.

Also remember this still is VERY VERY sticky so make sure you don't spill it where you don't want it to go :)

We sell multitudes of this stuff and countless amount of times people have come back under-estimated how sticky it is. But once you are all set and sort your ratio out you will love it.

Where would one source terpenes from?

Hi dude
Once they're isolated, terpenes are completely legal in the UK so there's a bunch of sites you can buy them from with a simple internet search.
Hope this helps

Thanks buddy, I was wondering! Thinking that I should make a healthy switch after smoking for 35 years!

No problem mate there's some tasty ones out there!
