That's a good point I hadn't considered. I'll hold off my zero patience and try this tonight and report back.
I did actually get a little more vapour using a different batch even though it wasn't quite as dry as the other one.
Can anyone advise if a small marble might work like the glass flowers?
Good to hear, work with it, it's technique sensitive for sure. Pretty narrow minded in what it will do, kinda like some people.....
I never tried marbles, but I tried a couple different sizes of glass beads. They're better than noting, but basically from a surface area standpoint (what we really care about) it (a sphere) is the worst possible shape. Minimum surface area for the mass, which is why our planet is round. The flowers take this idea (surface area per gram if you will) to the extreme the other way. Better than more herb, but not much.
If you go with beads, go small, that too favors surface area (all else being the same).
You can get a pinch of flowers for ten bucks or so from Amazon or Ebay, I suggest you order some and give them a try, I don't think a single poster hasn't found them to be a big benefit? A PITA to some, and Nigel loves to break them, but they do boost vapor output and use less herb doing it.
