STM Canna has a variety of configurations available for their top and bottom trays. You can produce 72 or 143 pre-rolls per run, and how many pre-rolls you want to produce daily, will determine which configuration will work best for you. One additional factor to consider is what size pre-roll you want to produce. STM Canna offers you trays in 5 different sizes which include 84mm .5gram +/-, 98mm .75gram +/-, 109mm King Size 1 gram, 70mm Dogwalker .35 gram and the cigarette size. You will also want to determine if you want to use an automatic closer to finish off your pre-rolls as this will affect which tray combination you choose. We will gladly go over your options and figure out which configuration will work best for you, as will the STM Canna team. If you are interested in some STM Canna equipment, you should get a general idea of what your pre-roll goals are and give us a call. We will do all the research for you and get you the best possible price with shipping included and all the options accounted for.
