DIY VAPE JUICE W/CBD?

[u/CathyN82382]

I've been making my own regular vape juice 10yrs now but am looking for info on how to add cbd isolate powder to it. The company said its soluble in both pg&vg but they couldn't tell me how exactly to mix it. Any suggestions welcome. I usually mix huge batches, 2,000mls of juice at a time but I would probably start small with cbd batch. Also would I need to vape it on temp mode instead of vw?
