A Deep Dive into the Economics of Home Cannabis Growing vs. Dispensary Purchases in California

In California, where cannabis is legal for both recreational and medical use, you’ve got choices. You can walk into a licensed dispensary and buy top-shelf flower or you can grow your own at home. But which one actually saves you more green (money, that is)? Let’s break it down, cost by cost, gram by gram, plant by plant.

Dispensary Prices: Paying for Convenience

Upfront Costs (Dispensary Style):

• Price per gram: $8–$20 (or more for premium strains)
• Eighth (3.5g): $35–$70
• Ounces (28g): $160–$400
• Taxes: 15% excise tax + local sales tax (varies by city)

Example Monthly Spend (Moderate User):

• 1 oz/month = $200 (average) + tax ≈ $230–$250/month

What You’re Paying For:

• Convenience
• Consistency
• Lab-tested products
• Wide variety of strains, edibles, and concentrates
• No growing hassle

Hidden Costs:

• Premium pricing for branding
• Less control over growing practices (pesticides, nutrients)
• Supply chain markups

Home Growing: DIY for High Yield

California Homegrow Law Highlights:

• Adults 21+ can grow up to 6 plants per household
• Indoor only in most cities unless local laws allow outdoor
• No license required for personal recreational grows

Startup Costs:

Ongoing Costs per Grow Cycle (3–5 months):

• Electricity: $25–$75/month
• Nutrients & water: $30–$50
• Misc supplies: $20

Yield vs. Cost

Average Yield Per Plant (indoors):

• Beginner: 1–4 oz
• Intermediate/Expert: 6–10 oz or more

6 Plants (Modest Indoor Grow):

• Low end: 6 oz total
• High end: 30+ oz total

Cost Per Ounce (Homegrow):

• First grow (startup included): $35–$100/oz
• Future grows (startup paid): $5–$15/oz

Compare that to dispensary prices: $160–$400/oz.
That's up to 90% savings per ounce if you stick with it.

Time, Labor & Learning Curve

Growing your own weed isn’t set-it-and-forget-it. You’ll spend:

• ~10 minutes/day checking plants
• Weekly tasks like watering, training, pest control
• A few hours trimming and curing post-harvest

Learning curve:

• First grow might yield less or run into issues (mold, pests, nutrient burn)
• But each cycle gets easier, especially with help from guides and grower communities

Added Value of Homegrown Cannabis

• Strain customization: Grow what you like
• Clean product: Total control over what goes into your bud
• Sustainability: Fewer plastic containers and less transportation
• Therapeutic benefit: Many find the process relaxing and rewarding

And let’s not forget: Gifting, trading, or sharing with other adult Californians is legal too.

Is It Worth It?

Verdict: If you're a regular consumer with time, space, and a bit of patience, growing your own cannabis in California is absolutely worth it. After one or two harvests, you’ll be rolling in bud and savings.

Pro Tip from the Pros:

Want to start with a single plant and minimal investment? Try a 1-plant grow tent kit, autoflower seeds, and some organic soil - total cost under $300. You’ll still save money and learn a ton.
