In case I missed any questions, let me know:
The Cloud can be hit on a table or held in your hand, ala Purple Days.
The herb chamber sits in between the Cloud and the HydraTube. I'll show you a picture when my partner brings one by my studio, much easier to show than to explain.
As of now, the HydraTubes are 18mm but if you wanted to use it with your PD instead of the Cloud, I am sure you can find a 14.4 to 18.8 mm adapter, they are fairly easy to find.
Currently, there is no wait list and, it will be a first come, first served basis available at
www.vapexhale.com
and yes, these are just the first HydraTubes, many more to come. Waffles, gridded percs, and many others are all on the roadmap.
