CHEM-D and JACK HERER are two of the most popular strains ever. When you put them together you get CHEMJACK. A fully flowered plant will produce a sweet and sour smoke that has a strong head high and mild body effects. This is a plant that will eat nutrients (like its Chem-D mother) at a high rate when flowering. The CHEMJACK will usually need more nitrogen than other strains. It will need the nitrogen longer into flowering also.
