Sandwich is ok to medicate, but I do not like big difference in extraction time between the 2 with such a small load. The flower usually makes it taste harsher after the first hit or two.
But fret no more........there is a much much better way to use full melt or other concentrates of the like.
(I'm sure many have done this well before I have, but I do not recall it laid out like this for others to figure out)
Take any metal concentrate pad and "unwind" it to make a smaller section to shape into a pad that is easy to fit the tip. In this case I used about 60% of a S&B dosing capsule pad. The 2 left overs you see are shorter than the piece in the tip. I usually make them now so there is about 2-3mm of space above the pad to the tip end. This will help keep the cap from being a cleaning issue.
I use about 4-6 times before I clean off the pad, and use another that is waiting in rotation with several other pads.
This setup will hold the trates much longer and you can use a bit bigger load if you want. I heat up without anything in it.....pull the cap off with a finger protector and load when warm. Most of it would not melt in for me as I waited to long to get it on the warmed up pad....but as long as you keep the trates from being over the tip end..all is good!
I use the my Skeletor IH portable and hold it upside down over the vapcap. I can pull directly off the vapcap this way with concentrates, but not with flower. For this I am super happy to use my trates in more stealth situations and such.....or late night in bed for quick medication when I have issues sleeping.
This is pretty easy to do actually, just get a regular pliers and a needle nose one to pinch the pad into a rectangle column. Then you just start to compress it vertically and get it to be as dense as you can and still fit in the tip. Then press it in with a tool and get it to just fill up the tip maybe 50-75% of the chamber so it has that little bit of space at the top.
Hope this helps some with a new way to use concentrates and a new way to use your dynavap! ✌
