Disclaimer! Please be aware that in many places, it is illegal to grow marijuana and the penalties for doing so can be quite harsh. This guide is intended to be used only if it is legal for you to be growing marijuana. We strongly discourage breaking any local, state, or federal laws. We also discourage using any of the seed banks to which we link if growing marijuana is illegal for you. If you choose to break any laws, you do so at your own discretion. Do research to learn about the laws where you live before growing any marijuana. For the United States, NORML maintains a state-by-state listing of marijuana laws and penalties. This guide was compiled from resources freely available over the internet. The author, Owen Washington, has never personally grown or harvested marijuana.
