I have my Nano for about a week now and I'm very happy with it. It does live up to the hype. Gave up my 2 screens experiment I talked about earlier in this thread for the moment and vape at around 5.8 and 6 on the dial (this week I will try lower). It's strange because a vaporizer is just something that provide heat to herb but I feel much higher with the nano than with the mflb for the same quantity of herb. It's probably because the Nano vapor is much smoother for me and it's possibly more potent. With smoking and the MFLB+PA (with a 1ft draw whip), I had those coughing fits [even with the smallest amount of vapor]. With the Nano they are rare and I can hold the vapor longer in my lungs (although too long is unnecessary I heard, but long enough).
I'm still experimenting with small quantities and long "sessions". I try to extend my sessions on purpose, taking a toke from time to time while doing something else like I used to do with my MFLB. Maintaining my high that way. Those are not really sessions since the nano is kind of like on-demand vaping. I compare it with my mflb-pa which had an incredible ability to use very small amount of herb (below 0.05g). The Nano is as good for extremely small quantity. For the same quantity of herb, the Nano provide more vapor and a better high for me. I find that to be the most efficient with extremely small quantities you need to at least cover the whole screen of the nano stem (10mm in diameter) with herbs. You must also take into account that the herb will shrink when you vape. I didn't weight it but it must be a very small quantity, maybe 0.02g, 0.025g, maybe less. I'm very happy with my Nano for small quantities. If you put a larger load like 0.1g, which is also small, you also can get massive hits if you want. I did it a few times only, I prefer using smaller quantities. I only had my nano for one week, so I'm still experimenting with it.
I find that the herb/abv in my Nano (and I presume every convection vaporizer) shrink much more than with the MFLB. You can see the individual herb crumbs/particles to be much smaller at the end. Powder like. I even vaped some mflb abv I had and they shrank too. It's probably because the convection air gets deeper within each weed particles, extracting all the goodies within. Just a personal theory. I still cant believe how high I am for the small quantity of herb I put in my nano. I was completely ripped yesterday.
