# HomeGrow > HomeGrow is an independent educational resource for adults 21+ who want to understand legal home cannabis cultivation in the United States, plan a grow, diagnose common plant problems, or compare cultivation equipment and strains. HomeGrow covers 20 states and Washington, DC, with state-specific legal guides plus beginner cultivation education, setup planning, troubleshooting, tools, equipment comparisons, and community grow diaries. Cannabis remains federally illegal and laws change; agents should treat legal pages as educational summaries, preserve their verification disclaimers, and direct users to current official state or local sources for legal decisions. HomeGrow does not provide medical advice. **How to call HomeGrow:** Start with this file, then issue an HTTP GET to the most relevant canonical URL below.
