The bubbleman pen chronicles continue. I got my pen a couple of weeks ago now, so I have some experience with the device. Overall, I’m starting to like the pen though it does have its flaws. I’ll go into those later.
At first, I was less than impressed with the pen. I was able to melt some Zak Haze rosin and get it in there, but it was buttering up and sticking to the sides, so I lost quite a bit. Now this tank with the Zak Haze rosin worked and tasted pretty good and I was somewhat happy about it. Later the tank broke in my pocket. Luckily very little rosin leaked out and I was able to repair it. This has happened one other time, so now I make it a practice to remove the tank before I put it in my pocket.
I had ordered a second tank, so I filled it up with some Cannatonic rosin. This was easier to get in there, but the tank never hit. I would try and try, and it would just get hot with no vapor. If you hit it a few times in a row, you might get a small hit and the rosin would bubble bubble bubble. One time I hit it so many times, the o-ring blew and most of the rosin started bubbling out. It was quite a mess. Another time I hit it again and again trying to get hit and the battery’s protection circuit went off. It refused to charge. I let the battery alone for 24 hours and it was able to charge.
While the battery was down, I noticed the tank had a piece of paper thar read “do not use more than 14 watts to power the tank”. It got me thinking, is this a standard 510 thread? Yes it is! So I put the tank on my 510 battery and set it to 14 watts. If you have a 510 battery, you could just order the $14 tank. 
I decided to add some PG to my tank in case the rosin was too thick. these are designed to be diluted after all. I got a few hits from it, but did notice my rosin was quite dirty (a lot of small pieces floating around). So I decided to clean that tank well. I need to test it with some VG to make sure it will hit before re-loading it with some rosin.
Well I killed off the Zak Haze tank and decided to clean it. I was able to fix the tank further after it was clean. It’s a press fitting and I was able to get it to stay pretty well. When listening to Hash Church where Tony mentions you can use rosin, he started by saying you had to decarb it. I believe this serves two purposes. First, it was decarbing in the tank and causing all the bubbling. Second, THCA is what butters or shatters up, so by converting to THC, you are able to keep the rosin in a more oily texture. So I pressed out a gram of Zak Haze rosin and decarbed it at around 200*F for 20 minutes (until the bubbling stopped). I did loose some terpenes, which I guess kind of defeats the purpose, but it has been hitting like a train and tastes as good as hitting the decarbed rosin on the nail. Been hitting this tank all week.
