Hello friends, long time lurker first time poster.
We all know and love the Harvest Right freeze dryer, however there is no doubt that there is a LOT of room for improvement. During the latest hash conversation on bubbleman’s channel (looks like he was hacked unfortunately) Vessel life science suggests utilizing Leybold vac pumps instead of the default/oil-free HR pumps. Supposedly, these pumps allow you to achieve a much deeper vacuum and noticeably reduce dry times and preserve terps. I was Just wondering how many people here have played around with vacuum pumps other than the default HR’s. And in addition, if anybody has played around with other interesting modifications/3rd party additions. I know there is also a lot of interest in custom software hacks as well. I personally love the idea of an open source freeze dryer, and figured this would be the spot to ask if anybody has attaempted to accomplish this.
