I noticed that the HES for me has made it so that the airflow is less restricted but I think my vapor is slightly thinner.
I think there's great wisdom here. Of course there's no more vapor.
Heat makes vapor, not letting more cold air into the game. In fact, the cold air robs heat and therefore means less vapor. Not in volume, but in THC content. I know I'm about to get hit with 'that's not how it works for me' posts, but that's how it works in Physics and Chemistry. The draw gets easier (so you can get a 'bigger hit' easier) but the concentration of good stuff has to suffer. It's a rule.......
There also seems to be a lot of concern about battery life again. Please let me repeat my 'take' here? Capacity goes down over the useful lifetime of the battery. Some things (like letting it get too hot, deeply discharging or a habit of 'always recharging fully') can make this worse. In general you should get 300 or so cycles (charge/discharge) from the pack, twice or more if you practice some battery discipline. I recommend never 'running it to the bottom' (recharge after the last LED doesn't light, even though the Solo will do a few more sessions before locking you out) and if you can stop the charging when the top LED lights but before the charge LED stops flashing (this alone can double or more your battery life).
Finally, it's easy enough to test useful capacity, but you need to 'standardize the load'. The amount of draw and the step level have a huge impact. Too big to ignore. I suggest you try what I do: Run at step 7 with no stem (top open) and no forced airflow. This will be a uniform run, same every time. My tests show you should get about 'a (12 minute) session per step on the battery meter'. That is say 8 such sessions for a fully charged (have to fully charge here to control that part) battery. I replaced my pack with a couple of 'home made' ones when it got to 4 or 5 sessions under those conditions.
Regards to all.
