We use both dry and wet, but freeze both before processing.

We've found that wet material often provides a stickier, more flexible bubble hash.

When the material is dried, it is more likely to break up and end up in the final product, but often this plant material carries other cannabinoids that are beneficial.

We don't notice any loss of potency from using wet material as decarboxilation (the process by which THC becomes active) requires heat and occurs during smoking or baking.

Using wet material does make it more difficult to calculate return percentage unless that is all you use.
