Saved a batch
You guys saved me from losing thousands of dollars in hash when my freeze dryers lost power and did not continue the cycle when power came back on; I got a notification and was able to get to the lab & start the freeze dryers again. Also a few times the freeze dryer did not achieve vacuum after I had left and the notifications saved me.
Hours saved
This is mandatory for mastering your freeze dryer. Saved countless hours going back-and-forth to the lab. These guys are tackling the last frontier of hash. Great for troubleshooting and fine tuning your freeze dryer, it also allows you to check in on them from anywhere - from your bed to a plane. No more guessing or worrying about your batches when you're away.
Away from facility
I no longer worry about coming in and finding a freeze dryer stuck at a weird point or worse, errored out and destroying a batch of hash. We're now able to plan our time better and understand when our hash is ready for the next stage rather than just guessing. The device and platform are fantastic - we can finally see exactly what's happening in real-time.
Run history
HashyLink has transformed my freeze drying process. Setup with my Harvest Right was incredibly simple, and now I get real-time pressure data and instant alerts sent to my phone. This lets me end the process at the perfect moment to preserve those delicate terpenes and volatiles. If you're serious about hash quality, the HashyLink is indispensable.
Overnight alerts
This is a must-have tool in my lab. From data tracking to alerts, it has made the work week smoother and worry-free. I can monitor remotely and catch issues before they become problems. The real-time data helps me optimize every batch and dial in consistency. HashyLink takes the guesswork out of freeze drying and gives me confidence that my equipment is running perfectly even when I'm not there.
Repeatable process
HashyLink let us monitor our mTorr levels, allowing us to shave a minimum of 5 hours off of our normal dry time. That's the only change we made during this wash, and we think this is our terpiest jar we've made so far.
Reliable monitoring
HashyLink has completely transformed how we manage our freeze-drying process. The setup was seamless, and the team was incredibly knowledgeable. What really stands out is the ease of use and reliability of their system. Whether you're in biotech, pharma, or any industry that uses freeze dryers, I highly recommend HashyLink for anyone looking to upgrade their monitoring capabilities and improve overall control.
Community support
I bought HashyLink from Lowtemp after getting a Costco freeze dryer with no experience. The real-time monitoring prevents screw ups. But the surprise was the worldwide hash making community - Friday Discord classes welcome everyone from processors to home users. Chase helps with setup and community access. I highly recommend HashyLink for the hardware, customer service, and the amazing community.
