Review on Goabroa Hygrometer Thermometer Temperature Fahrenheit by Patrick Lets

Needed in my grow tent in Oklahoma where the humidity is sometimes 40% in the morning and then 90% 2 hours later, it's outdoors. In my tent, with the lights on and only watering, the humidity rises to 80%. Sometimes I use a dehumidifier when the lights are on to get them down and a humidifier to keep them in the 50% to 60% range. This little hygrometer is small but very accurate to within 0.01. I compared it to the expensive hygrometer we use in our large grow room. If you want a good buy at a very reasonable price from this seller fast shipping just a few bucks free shipping and exchange and it updates every 2 seconds and i love this feature. Very good and reliable product, thanks to the seller for the fast delivery. Johnny J. Okla, Medical Marijuana Producer (Legal Producer)
