iWantClones ships HpLVd-screened cannabis clones to every Montana ZIP code under the federal 2018 Farm Bill hemp framework. Montana legalized recreational cannabis in November 2020 through Initiatives 190 and CI-118 (57% support), with retail sales beginning January 2022. The framework is in Montana Code Annotated Title 16, Chapter 12. Adults 21+ can possess 1 oz of flower and cultivate 2 mature and 2 seedling plants per person, maximum 4 mature and 4 seedling per household.
Montana’s short cold-climate growing season and intense mountain UV create distinctive cultivation challenges.
