Should be somewhere in the 280-330C range. Just a heads up, Vapir One is absolutely the worst vape you can buy. Most of it is made of plastic and the hits taste like burnt popcorn which can't be good. Compared to other vapes, the high was literally shit. You can sort of feel a small head high afterwards, but not very significant.
wow bud vapes at 180-200 degrees celcius so if it needs 300 to vape it cant be good haha. I used 220 on my v-tower for a bit but it was too high and 200 works just for me. you going to have to play with and get your own preferance really. higher temp will give a thicker vape that is almost burning... and at 300 you would definatly be burning not vaping.
