Was like a kid again unwrapping the e-nano. Currently practicing and appreciate if you guys could post your abv stash so I could see if I'm combusting or not.
The E-Nano was my first convection vaporizer. One thing I noticed was the ABV was much lighter than with a conduction vape, even with a more thorough extraction. At 6.5-6.75 my spent ABV is still a fairly light green. It takes temps of 7+ generally to get it even a medium brown, and that is very thoroughly extracted. Depending on the strain, I can usually fully extract at a little less than 7.5, and it is a dark chocolate shade of brown at that point, but the flavor is not worth the little bit extra THC to me.
I'm lucky to have fairly easy access to fairly high quality cannabis at fairly low prices. I'm sure others will milk every last drop while vaping. I save my ABV for cooking so I don't mind leaving a little behind when vaping. Might as well pack a new bowl and have some more fresh amazing flavor.
For this reason I don't like to adjust temp in the middle of a bowl. I almost always pick a temp and stick with it.
For all the new owners, one thing I can't say enough is less is more. You will generally get almost as many hits with .025 grams as you will with .05 grams, all else being equal. For example, .025 grams at ~6.5 temp usually gives me 3 hits. If I pack .05 grams at the same temp I might get 4 hits but I will have to stir after almost every hit.
For herbs I have two main modes of operation. For pure flavor I use lower temps, 5.75-6.25, and .05 grams. Depending on strain I can get 5-10 hits out of this.
For quick extraction and effects, I use higher temps and smaller loads. I like 6.5-7 on the temp dial with about .025 grams lightly tamped in the stem. I get 2-5 nice clouds from that depending on strain.
When using concentrates I like to use 7-7.5 with cotton and 7.5-8.5 with steel. I was having trouble using steel at lower temps but I adjusted the pad to fit the dry stem better and now it's working great. I find the cotton to be cleaner and easier to deal with but it doesn't taste as good as the steel.
Edit:
@Ganja J, just saw your edit. If you are burning bud at 5.5 there might be an issue with your nano. I find it pretty much impossible to combust even up to about 7.5 depending on strain. I hit it for upwards of 20 seconds sometimes.
You might also be packing it too much, that could cause the top part closest to the heater to combust. Try using just enough cannabis to cover the screen, ever so slightly tamped. You should be able to get at least one or two big clouds out of that at the right temperature. Just dump and reload. If needed break up/grind a little pile in advance. It's actually easier and faster to do that than constantly stir and tamp one massive load.
