Jeff Zorn is the founder of Cannabis Training University (CTU), an online cannabis school with 50,000+ students since 2009. CTU is an IACET Accredited Provider, and its courses cover cannabis cultivation, business, medical cannabis, budtending, cooking, extraction and industry regulations.
Pick your state and tent. You get the LED wattage for your light target, the exhaust fan size, what it costs to run at your state's electricity price, a climate target for each stage, and the number of plants your state's law allows.
About the store links: none of the store links on this page are affiliate links today, and CTU earns nothing from them. If that changes, each paid link will be marked "paid link" right next to it. We list gear by what fits your plan.
Sized to your tent and plant count. Prices change, so we link to the store instead of quoting them.

The Indoor & Outdoor Growing course covers lights, airflow, climate, watering and feeding, from seed to harvest. Now includes Growing Autoflowers.
What each state allows at home, from CTU's state cannabis law dataset, checked against the statute or regulator. Where we could not confirm a number from the official text, we say "Check the law" instead of guessing. Local rules, landlords and HOAs can be stricter. This is general information, not legal advice.
