However , there is more to growing quality cannabis than just quantity and cost . There is also the matter of how good it is . For the scientifically minded , there are lab tests than can report on tetrahydrocannabinol ( THC ) and cannabidiol ( CBD ) levels along with more information that can be had from such tests . While someday all aspects of quality may be possible to test for , the technology hasn ’ t yet gotten to the point of being able to replace a human tester for matters of taste , appearance , effect , and personal preference . A printout of the terpenes and flavonoids may be a fair place to get suggestions from , but it still takes a human to report on the human experience of it . Although the finer points of rating a plant are largely artistic and subjective , responses don ’ t have to be . To set up a simple double-blind test , first take identical opaque containers for each variety to be tested . Write the name of the variety on a piece of paper and seal in an unmarked envelope . Put the sealed envelope into the container with the matching cleaned weed . Have a friend mix up the containers while you are out of the room and can ’ t see them . When you return , mix up the containers again with your friend out of the room so neither of you have any idea which container has which cannabis . Mark each container with an arbitrary number or a letter . While smoking from each , keep track of reactions from the weed . Questions should include things like “ Which do you like the best : A , B , C , or Can ’ t tell ?” and “ Describe the flavor of each .” Record and tally the results from each participating tester . Since the envelopes contain the real identity of each container , after the tests have been completed , the envelopes can be opened in turn and associated with their lettered responses . Why go to the trouble of a blind ( or in this case double-blind ) test ? Because humans are very suggestible , and some variety names sound better than others . Cannabis labeled “ top shelf ” or “ mids ” tends to influence the reactions of the people who smoke it . Relabeling the smoke into something innocuous helps minimize the influence . If practical , even the person handing out the weed shouldn ’ t know what types are being sampled , as their behavior can have an influence as well .

Although it involves some basic math and effort , by quantifying the results of a harvest , a gardener can use the data collected to improve the efficiency and quality of their harvest . In this current time of reduced prices and lower profit margins , expense versus return is particularly important for commercial growers since it affects their bottom line . Home gardeners can be less efficient since they only have to beat retail pricing to come out ahead and don ’ t have to make a profit against wholesale pricing . Crunching the numbers may not be as fun as some aspects of growing cannabis , but it can be a useful tool .
