i place the screen a little further down than the epick goes ,when i measure it and i never fully place the heater in their.
still learning new things with it. but i didnt knew 6.5 was the was the best temperature
Not necessarily the best temp setting for all. Varies by nano, and even more by personal preference. I've used mine in all sorts of ways with different temps, distances and everything else. For me the best - or most used I should say - is 2-3 hit load with heat very close. I even have marks on my tampers (most often a golf pencil), so I can keep the distance between heater core end and load at less than 2 mm. If through a bubbler I'm usually a hair above 6.25 or so. Dry a bit below (6.1?) or sometimes as low as 5.5. This is MY favorite. No need for it to be yours. Though I will say this seems to be the most effective way to get best flavor and effect while using the least amount of material.
All those other variables come into play, too. I still think one of the primary reasons this vape is so well loved by most who try it is my way works great - but many others work great too - and you can get it to do more what you like or whatever anyone else likes easily once you get to know it.
Two things I mention above should make it work better no matter how you use it, though. Dry material (not crumbly, but pretty damned dry) and clean screens are key IME.
What I really do enjoy, and don't see as much of as we used to here, is when people share their particular methods. It's been a while since I've seen anything new (and maybe all possibilities have been explained, but I doubt it!), I usually give them a try if I haven't before. I'd have to go check the dates, but IIRC I had my nano as my daily driver for about a year before I was turned on to the 2+ hit method I now love so much. It just hadn't occurred to me to turn the heat down as low as 6.25 and move the load closer. Before that I was up around 7 with a bigger gap between load and heat, and larger loads. It worked great, and I'd probably still be doing it if not for the suggestion to try the other. So try this, and try whatever else. It's a very versatile vape!
