Section R. 420.303 - Batch; identification and testingRule 3.
(1) A cultivator shall uniquely identify each immature plant batch with a single batch name and record the information in the statewide monitoring system. Each immature plant batch must consist of no more than 100 immature plants.(2) A cultivator shall tag each individual plant that is greater than 8 inches in height from the growing or cultivating medium or more than 8 inches in width with an individual plant tag and record the identification information in the statewide monitoring system.(3) A cultivator shall separate the plants as the plants go through different growth stages and ensure that the plant tag is always identified with the plant throughout the growing cycle so that all plants can be easily identified and inspected. A cultivator shall ensure that identification information is recorded in the statewide monitoring system in accordance with the acts, the marihuana tracking act, and these rules.(4) A cultivator shall destroy the individual plant tag prior to packaging. Once a tagged plant is harvested, it is part of a harvest batch so that a sample of the harvest batch can be tested by a licensed laboratory as provided in R 420.304 and R 420.305. A cultivator shall separate the harvest batch by product type and quarantine the harvested batch from all other marihuana and marihuana products when the marihuana batch has test results pending. A harvest batch must be easily distinguishable from other harvest batches until the batch is broken down into packages. A cultivator may not combine harvest batches.(5) Before the cultivator transfers or sells the marihuana product to a marihuana sales location, a sample of the harvest batch must be tested for all required safety tests by a licensed laboratory as provided in R 420.304 and R 420.305. All test results must indicate passed in the statewide monitoring system before the marihuana is packaged for sale. A marihuana product from harvest batches may not be transferred or sold until tested, packaged, and tagged as required under subrule (4) of this rule. A cultivator may not transfer or sell marihuana under this rule to a marihuana sales location if the package contains more than 1 harvest batch.(6) A cultivator may transfer or sell marihuana to a producer without first being tested by a laboratory if the marihuana product will be processed. After the producer has processed the material, the producer shall have the sample tested for all required safety tests pursuant to R 420.304 and R 420.305. A producer that received a package under this rule that has not been processed may transfer that package to another producer without having the package first tested by a laboratory for extraction.(7) After test results indicate passed test for all required safety tests and the harvest batch is packaged, each package must have a package tag attached. A cultivator shall ensure this information is placed in the statewide monitoring system in accordance with the acts, the marihuana tracking act, and these rules.(8) A cultivator shall not transfer or sell any marihuana product that does not have a package tag attached and is not recorded in the statewide monitoring system in accordance with the acts, the marihuana tracking act, and these rules.Mich.
