Our team uses GemmaCert devices in all of our facilities for various purposes. For example, quick pheno-hunting, testing, tracking how grow conditions can affect cannabinoid development, and for determining optimal harvest times. We have compared results with our in house HPLC and the GemmaCert is very accurate
