About HomeGrow
An independent educational resource for home cannabis cultivation in the 22 US states and DC where it's legal.
Mission
Home cannabis cultivation has been legal in at least one US state since 2012. Today, adults in 22 states and DC can legally grow at home — but the information to do it well is fragmented across state statutes, grow forums, YouTube videos, and marketing-heavy seed bank sites.
HomeGrow consolidates the answers. Every page is built around a practical question a legal home grower actually asks: "What's legal in my state?", "What equipment do I need for a 2×4 tent?", "Why are my leaves yellow?", "How much does a harvest actually cost?"
What you'll find here
- State-by-state legal guides — plant limits, compliance rules, and FAQs for all 22 legal states + DC.
- Complete growing guide — seed to harvest, written for first-time growers.
- Plant problem troubleshooting — 30+ symptom pages with deterministic diagnosis paths.
- Complete setup guides — everything you need to grow in a 2×2, 2×4, 3×3, 4×4, or closet.
- Free cultivation tools — AI plant-health diagnosis, VPD calculator, cost calculator, grow-timeline planner.
- Community grow diaries — real users sharing their grows day by day.
- Equipment recommendations — tested picks for lights, tents, fans, filters, and more.
Who's behind HomeGrow
HomeGrow is built and edited by Matt Kilmer — an independent software engineer and home-cultivation enthusiast. It is not funded by dispensaries, seed banks, or cannabis industry investors. It is not backed by a media holding company or a VC round. Every page is written or edited by Matt directly.
This independence matters because it determines what gets written and how. Dispensary-owned sites push consumption; seed-bank sites push their own strains; stoner-culture blogs don't prioritize legal accuracy. HomeGrow was built to fill the gap: accurate legal information, genuinely useful cultivation guidance, and honest product recommendations — all written for adults in the states where this is legal.
How HomeGrow pays for itself
HomeGrow monetizes through affiliate relationships. When readers buy equipment through links on the site, the site earns a small commission at no extra cost to the reader. Primary partners:
- Amazon Associates for growing equipment (lights, tents, fans, nutrients, testing gear).
- Fast Buds for autoflower seeds (with a 15% reader discount via code
HGAPP).
Every affiliate link is disclosed on the page where it appears. Product recommendations are based on the actual merits of the product — never on commission rate. Full affiliate disclosure here.
Editorial standards
Legal content:State legal pages are reviewed against official state statutes and cannabis control board publications. When laws change, the affected pages are updated and a "Last reviewed" date is bumped at the top of the page.
Cultivation content: Written from cultivation experience and supported by extension-office horticulture research and peer-reviewed studies where applicable. Equipment recommendations are based on direct use, published specifications, and cross-checks against grower-community consensus.
What HomeGrow is not: HomeGrow does not provide medical advice — cannabis has real effects and users should consult a physician about therapeutic use. HomeGrow does not provide legal advice — state laws are complex and change frequently, and specific legal questions should be directed to a licensed attorney in the relevant state.
Age gate
HomeGrow is intended for adults 21 and over. Home cannabis cultivation is subject to strict age requirements under every state's legal framework. If you are not of legal age in your state, please leave the site.
