A Quick Guide to Cannabis Flower
Cannabis flower is the unprocessed, dried bud of the female cannabis plant — the form most people picture when they hear the word "weed." It's also the most versatile: you can smoke it, vape it, roll it into joints, pack it into pre-rolls, or use it as the base ingredient for homemade edibles, tinctures, and concentrates. Quality flower stands out in three ways: dense trichome coverage (the frosty crystals where cannabinoids and terpenes concentrate), a vivid color profile beyond plain green, and a complex, layered aroma that hits before the jar is even open.
California flower typically tests between 18% and 32% THC, but the smartest shoppers learn to look past the headline number. Two flowers at 24% THC can produce wildly different experiences depending on the terpene profile — myrcene-dominant strains lean relaxing, limonene strains lean uplifting, caryophyllene strains lean clear-headed and physical. Lab-tested California flower lists both cannabinoid percentages and the top three or four terpenes on the package, which is the most reliable way to predict how a strain will actually feel.
At Atrium we curate flower across price tiers — from value ounces under $100 to top-shelf eighths from California craft cultivators. Whether you're looking for sativa-dominant strains for daytime, indica-leaning crosses for evening, or balanced hybrids for any time, our flower menu is filterable by strain type, THC range, and brand. All flower is stored in temperature- and humidity-controlled cases until it leaves the store.
About Cannabis Flower
What is cannabis flower?
Cannabis flower — also called bud or weed — is the dried, cured bloom of the female cannabis plant. It's the most traditional form of cannabis and contains the highest concentration of cannabinoids and terpenes. Flower is typically smoked in a pipe, bong, or rolled joint, or vaporized in a dry-herb vaporizer.
What's the difference between indica, sativa, and hybrid?
Indica strains are traditionally associated with relaxing, sedating effects. Sativa strains are linked to energetic, uplifting effects. Hybrids are crosses that combine traits from both. Modern cannabis science emphasizes that terpene profile and cannabinoid content have more influence on the experience than the indica/sativa label alone.
How do I know if a flower strain is high quality?
Look for dense trichome coverage (frosty appearance), vibrant color, and a strong, complex aroma. Properly cured flower should feel slightly sticky but not moist. Lab-tested flower with a full cannabinoid and terpene panel gives you the most objective quality information.
How should I store cannabis flower?
Store flower in an airtight glass jar at room temperature, away from light and heat. Add a two-way humidity pack (62% RH) to maintain ideal moisture. Properly stored cannabis retains its potency and terpenes for 6–12 months.
What does THC percentage actually tell me?
THC percentage indicates the concentration of tetrahydrocannabinol in the flower by weight. Most California flower tests between 18–32% THC. While higher THC delivers a more intense effect, it doesn't guarantee a better experience — terpene profile, freshness, and cure quality often matter more than the headline THC number.
What are terpenes and why do they matter?
Terpenes are aromatic compounds responsible for the smell and flavor of cannabis. The dominant terpenes — myrcene, limonene, caryophyllene, pinene, linalool — also shape the strain's perceived effect through what's called the entourage effect, interacting with cannabinoids in your endocannabinoid system.
How much flower is in a typical purchase?
California dispensaries sell flower by weight: 1 gram (one bowl), 3.5 grams (an eighth), 7 grams (a quarter), 14 grams (a half), and 28 grams (an ounce — the legal personal-possession limit). An eighth typically rolls 3–5 joints depending on size.
Can I get cannabis flower delivered in Los Angeles?
Yes. Atrium offers same-day cannabis delivery throughout Los Angeles from both our Woodland Hills and Valley Village locations. Order online, verify ID at the door, and your flower arrives in tamper-evident, child-resistant packaging.
