Here's another peice of advice. If you have a label maker, make some indexing strips, like this
It takes the guesswork out of getting a repeatable vape.
The marks on mine go from one to eight. The mark on the tank base lines up with the eight when the liquid feed is closed. I don't have any index on the air feed, I jut adjust it and the top cap by feel and sound. If it draws like a cigarette the air feed is correct and if I hear air getting in at the top cap, I'm good to go.
By doing this I know that for a given liquid (halo TriBeCa in this case) I get a good result when the UFS is cold with the liquid feed at just over 5. As it heats up, I close it a little to about 5.5. When I step away from the GG for a while, I close the liquid feed and the control ring. Coming back an hour later, dial the liquid to just over 5, open the air to the right draw restance, do a couple quick priming draws and light it up. Minor adjustments as it heats up and it's good to go.
