Thats about right, 3-4 sessions with mine was all it took to figure out the perfect technique for me and stopped any black/dark spots from appearing. It sure is an amazing devise.
And Oh boy the firefly 2
My FF relationshio so far has been mostly good. Last week at the weekly poker game, I brought the FF to really run it through it's pace with a crowd and to see how well it holds up. All of the attendee's have used and own many different vapes (we tend to bring all our new stuff to show off) so no one was a true vaping newbie. We had about 7 to 8 people playing.
I have an extra charger and battery so they were essential to bring as well. During the course of 6 hours or so, we packed it maybe 10-12 times, getting about 10 hits or so each bowl. Each battery lasted 3-4 bowls. and the re-charge time was more than fast enough to keep the FF constantly supplied with power.
It was packed by multiple people with different varieties of herb. So some consistency to the grind or pack technique but probably not very much. It did very very well with the crowd. We really didnt have any issues with un-even ABV since most of the herb was the dense somewhat stickier variety, it vaped real evenly. It tasted really great, battery life was very good and the vape was enjoyed by all.
The issue I am running into now, is I only have some really dry somewhat fluffy purple herb. It's hard to get it to a good medium grind without it crumbling and any herb in contact with the screen at the bottom will darken up quick. It tastes great for a second but goes to toasted popcorn real fast. It's not really combusting but really really dark brown and tastes harsher.
To counter this, I did as medium a grind as I could with it, then packed the FF almost full, THEN laid a ceramic disc screen on top of the load and placed the lid on it. The ceramic screen fits perfectly over the bowl but doesnt completly fill the window cavity in diameter or thickness of the screen. There is just enough room to allow air to flow.
Then I flipped the FF upside down.
I dry hit it a few times, in the hopes of pulling any bits in contact with the screen away from it. Then tapped it upside down in my hands a few times.
Then started with a 3 second warm up and pull. Seemed to work better to keep the herb from contacting the screen, and I didnt get the almost charred bits and the taste was good.
So I repeated this for a few bowls with this herb. It seemed to work great. I was worried that the ceramic disk would retain too much heat and affect the function, but it worked fine. In fact, I think the heated ceramic disk helped this particular herb vape a bit more evenly. It worked but seems a bit much to do it everytime.
All in all, shes been good to me and is a real beauty in a crowd.
I just need to stay stocked with some tighter stickier herbs for the FF, and leave the really dry stuff to my LSV.
