While I don't know the exact temps that each is hitting, I think that outside of traditional ball vape designs with PIDs that give temp read out, you might want to look into the Herborizer. Still the most flavorful hits I get and hits hard enough to be a heavy hitter in my book (tho not as hard as ball vapes, where you start trading flavor for intensity of hit). A big favorite of Jerry
@stickstones of POTV and you can see his thoughts on some Troy and Jerry show episodes. While Troy goes for MORE BIGGER, Jerry is more of a low temp flavor guy.
I also like the Couchlog idea, that would be a log/ball combo. I like that the recently announced JoDa glass WPA lets you adjust the screen to heater distance, and if his XL Nano stems are anything to go by, you should have very nice tight tolerances. (XL Nano isn't a bad idea either with your preferences). Also a big fan of how close you can get the CL heater to flower in the
@VGOODIEZ bowl for 14mm injectors. It even gives you a lil window below the screen to view the density of the vapor.
And for ballers, if you want low temps I recommend the diffuser style of the TKO or Zeal. Compared to injector style vapes, diffuser designs get flower and a larger surface area of it closer to the hot balls and coil, letting you run at lower temps.
A great seal between baller and bowl also helps. Best seal I know of from my experience is the TKO and the Infinity Bowl. Or for microdosing the "injector adapter" is actually used by many TKO users as a "Minfinity bowl" using the screw hole originally intended to attach to TKO baller head to hold a Minfinity handle from
@DFreeZ_Designs that let's you use it as a bowl instead.
Halogen heating could also work well here if I'm correctly reading between the lines of why you want low temps. Can't say what temps the Halo runs at, but halogen is great for unique flavorful extractions that I assume are pretty low temp judging by the clouds and what the ABV looks like. But that unique extraction still has great effects from its terp extraction.
Hope this helps.
