Ever since I saw a post here last week about using the Weedeater with *no* water, I've been experimenting. A long time ago the Arizer company discouraged me from buying a "water tool" for the Solo II, saying they felt it decreased the effect. I've used that vape a bunch with and without water, not really noticing much difference (caveat: lots of water definitely decreases the effect).
Like everyone here, I've been using the WE with water in the bong. But, now I'm appreciating what seem to be improved quality of effect and improved potency with not using water. If the goal is to cool the vapor, then a sufficiently large or long dry glass path should work too. Hooked up a dropdown to the Mobius Binary Matrix and I've been using it dry to my delight. I find it's more challenging to get just the right draw than with water in the pipe, but I'm genuinely liking this experiment.
Right now, running about a 1/4-1/2 shovelhead (lightly dumped in, not packed) at 670 degrees. Takes 6-7 hits before the bowl is all browned. It's a more delicate, nuanced way to use cannabis, but I'm really digging it. No big cloudy/milky puffs, but wow the efficacy is great!
I've been fantasizing about having this setup: a plastic mold about the size of a can of soda, to freeze ice in a small cylinder. Then, a very simple pipe: a long glass tube with a 14 mm joint in one end and the mouthpiece on the other. It will be made to wrap multiple times closely around a cylinder between the joint and the mouthpiece. So, you take a prepared ice cylinder out of the freezer, set it inside the glass coil, wait a minute or so and voila! A very cool dry hit. Soon as it melts substantially, replace as needed with another frozen cylinder. I might actually approach a glassblower about this one.
