Yes. Not much tho. I have one and have dried some bud the first time I used it. They came out bone dry lol. Like turned to powder. Then... immediately started absorbing moisture from the air. Smoked some... real fresh Terpy taste but also a strong green flavor of the unbroken down chlorophyll. Ive heard people get some interesting end product playing around with dry times and other various tech i don't really know about. I but it for drying hash. The flower things interesting but hard to do anything large scale cause the tray heights are so short you have to break everything down to fit in the drier.
