We require 2 grams of flower for a potency test, 2 grams for a microbial test and 0.5 grams for a terpene test. Therefore if you would like a sample tested for potency, microbial and terpenes we would require 4.5 grams. For concentrate we require 1/2 gram for each test, so 1 gram would be required for potency and residual solvent testing. For edibles we require one unit of the edible whether it is a single serving or multiple serving.
