Seeds & clones — please read: Grow Vault Supply does not sell seeds or clones. Those deals link to third-party seed banks and nurseries. Cannabis seeds contain negligible THC (under 0.3%) and are treated as hemp under the 2018 Farm Bill; sellers offer them as novelty, souvenir and genetic-preservation items. Whether you may legally germinate or grow them depends on your state and local laws — it is your responsibility to know and follow those laws before ordering or planting. Adults 21+ only.
