My current method of HA'ing, I use these awesome
vapor bros ceramic screens (fit is nearly perfect) as spacers to give more convection. Three on the bottom one on top, no screen in tong (not needed). Water tool tong is a must, even using dry imo, the mp/tong will never fall out since it's deeper than stock mp. Then I preheat the HA to green @ 375+ (started doing this lately versus loading and then heating), then once heated up I put the three spacers in, add grounded up bud (I prefer it for this method since it takes up less space, allows me to put bud as far from heater as I can), put one spacer ceramic screen on top, put my elite mp tong on top (this would work even better with the 2.2 water tong imo, more spacers can be put in), then voila! I have a very convective herbalAire water experience. It works just like a log would, upside down in bubbler, but it's a so much better experience with the herbalAire magic of no stir, even vape, and thorough extraction. I plan to make a nice video detailing the process and showing how awesome it works sometime soon.
Only cons for me are that I have wait a bit between sessions for at the least the ceramic spacers to cool off (have started pulling off tong after a bit of cooling, haven't noticed any damage as a result), and my bowl gets dirty and sometimes emits a vaped weed smell (just need more cleaning tho, ofc it is a bit harder since in this method of no cruc the bowl is the HA itself).
