Arizona allows adults 21 and older to grow a small number of cannabis plants at home. That makes the question of where to buy good seeds a practical one.

This guide covers online seed banks, local options, the state's home grow rules and three popular strains.

Online Seed Banks That Ship to Arizona

Most Arizona home growers buy seeds online. Seed banks offer a wide selection, published strain details and discreet shipping.

Below are two online seed banks that stand out.

I Love Growing Marijuana (ILGM)

ILGM offers feminized and autoflower seeds and ships within the United States from a U.S. warehouse.

What sets ILGM apart is its grower education. Its website has grow guides, a blog and a community forum.

ILGM also offers a germination guarantee. Check the current terms on its site.

Privacy is also a priority for ILGM, which ships in discreet packaging.

Herbies Seeds

Another top pick for Arizona growers is Herbies, a large European seed shop.

Its catalog spans seeds from many breeders, including classics, hybrids and newer varieties.

Strain pages on Herbies Seeds include customer reviews and ratings, which help you compare options.

Similar to ILGM, Herbies Seeds ships in discreet packaging. Check its shipping terms for the U.S. before ordering.

Some Arizona dispensaries and shops sell seeds or clones, but selection is usually small.

Local stock changes often, and you may not get breeder information or a germination guarantee. Online seed banks usually offer more choice and clearer product details.

The Legality of Marijuana Seeds in Arizona

Recreational and medical marijuana is legal in Arizona. Under Arizona Revised Statutes 36-2852, adults 21 and older may possess up to one ounce, with no more than five grams as concentrate.

Both medical and adult-use cannabis are legal in the Grand Canyon State, with separate rules for each.

Home cultivation is legal for adults 21 and older, with limits. An adult can grow up to six plants at their primary residence, and no more than 12 plants at a residence where two or more adults live.

Plants must be grown in a closet, room, greenhouse or other enclosed area with a lock that keeps minors out. They also must not be visible from public view without binoculars, aircraft or other optical aids.

Medical rules are different. Under ARS 36-2801, a patient may keep 12 plants in an enclosed, locked facility only if their registry card authorizes cultivation.

State law lets adults grow, so buying seeds to plant at home is common in Arizona. Federal law is stricter.

Seeds are a legal gray area. Under the current federal hemp definition, seeds at or below 0.3% delta-9 THC can count as hemp, which is why seed banks sell them as souvenirs.

A new definition in P.L. 119-37 counts total THC, including THCA, and excludes viable seeds above 0.3% total THC. The Congressional Research Service says that part now takes effect December 11, 2026.

Under federal law, marijuana remains a Schedule I controlled substance. A Federal Register rule published April 28, 2026 moved FDA-approved drug products containing marijuana, and marijuana covered by a state medical marijuana license, to Schedule III. Any other form of marijuana stays in Schedule I.

Should You Grow Weed Indoors or Outdoors in Arizona?

Your choice depends on your experience, budget and the local climate. Remember that any grow, including a greenhouse, must be enclosed, locked and out of public view.

Indoor Cannabis Cultivation

Indoor growing gives you control over temperature and humidity, which helps in a state with extreme heat.

Advantages include year-round growing and better privacy.

The downside is cost: lights, ventilation and cooling use a lot of electricity in Arizona summers.

Outdoor Cannabis Cultivation

Growing in a locked greenhouse or enclosed outdoor area uses Arizona's strong sunlight and costs less.

Benefits include lower equipment costs and the potential for larger plants.

Challenges include extreme summer heat, pests, and meeting the enclosure and visibility rules.

When to Sprout Weed Seeds in AZ

Indoors, timing does not matter. You can start seeds any time if conditions are right.

For enclosed outdoor or greenhouse grows, many Arizona growers start seeds in spring, roughly March to May, depending on elevation and local frost dates.

Best Strains to Grow in Arizona

Below are three popular options. Potency and yields vary by grower, batch and growing conditions.

1. Girl Scout Cookies Extreme

These feminized seeds come from a well-known indica-leaning strain family.

Feminized seeds are bred to produce female plants, so you don't have to identify and remove males.

Yields with Girl Scout Cookies Extreme depend on your setup and experience. Check ILGM's product page for its current estimates.
