The device has a comfortable ergonomic design that fits well in the hand.

When it comes to measuring ambient temperature and humidity, its performance was respectable, though we did notice some slight drift over longer monitoring periods compared to more dedicated hygrometers. The inclusion of a laser thermometer is a neat feature, but it doesn’t directly contribute to the continuous VPD monitoring that many growers seek for their cannabis grows. The build quality feels solid, with a good weight to it.

This device is specifically for the grower who wants to quickly diagnose localized environmental issues. For instance, if you suspect your light fixture is creating an unusually hot zone near the canopy, you can use the laser to get an instant reading without disturbing the plant. It’s less of a set-it-and-forget-it solution and more of an active diagnostic tool.

However, the lack of continuous logging or app connectivity means you’re manually recording data if you want to track trends. This makes it less ideal for those who want to automate their environmental monitoring or remotely check their grow tent’s best temp for cannabis grow tent conditions. The buttons have a slightly mushy feel, which detracts from the overall user experience.
