Hey I just vaping Cbd myself. I recently bought from DeltaLiquids in the U.S, they may ship out of the U.S not sure but check them out. I can say the following.

Their cbd works -

it smells very strong -

it's thick -

it needs to be diluted in some other ejuice-

flavors there aren't worth buying, you're best off buying the natural hemp flavored , I tried vanilla cream or whatever and it was good, the citrus flavor was so over bearing I couldn't hardly mix it with anything , very tangy and sour. any flavors you get from them will be very potent, so i'd say stick with natural flavor.

they have potency's from 150mg, 300mg, 600mg, 1000mg, and 1250mg . 30ml in all bottles- so definitely dilute it.

Since the juice is VG mostly I'd find a good PG/VG maybe 50/50 or something, something with a good amount of pg. helps make the juice a bit thinner but experiment I found some juices even with a good amount of vg dont do bad when mixed with the CBD it's just vaping that pure cbd will taste strong, be way expensive, and wand depending on how much cbd will be way to much of a dose so again highly recommend diluting.

as far as set up goes my buddy has bought vape pens that went for 25, and then he paid for a tank for another 20 or so? maybe 45 total set up? and when vaping he still feels it...

but me I went and bought a kanger nano tech the smaller ones not the giant ones, and it's great. I dropped about 80 but have seen them online for cheaper now, delta liquids actually sells them but look else where, pretty sure it's cheaper if you look around but you can check their site to see the set up im talking about.

Good luck
