Every product on a cannabis dispensary menu started as a seed or cutting in soil. Understanding how cannabis is grown the basics of the plant’s life cycle, what conditions it needs, and how cultivation choices affect the final product makes you a more informed consumer. It explains why products from different producers taste different, why organic growing matters, and why the label on a Vermont dispensary product means more than it might seem.
This is a plain-language cultivation overview, not a technical growing manual. It covers the biology and process at a level useful for any curious adult. For Vermont home cultivation rules, see the note at the end adults 21 and older can legally grow up to six plants under Vermont Cannabis Control Board regulations.
Cannabis as a Plant: The Basics
Cannabis is an annual flowering plant meaning it completes its full life cycle (seed, vegetative growth, flowering, seed production) in a single growing season. It is one of the oldest cultivated plants in human history, having been grown for fiber, food, medicine, and other uses across thousands of years.
The cannabis plant is dioecious meaning individual plants are either male or female. Female plants produce the resin-rich flowers (buds) that contain the cannabinoids and terpenes that make cannabis valuable for consumers. Male plants produce pollen sacs and are generally removed from cultivation before they can pollinate females (which would cause seed production and reduce the quality of the flowers).
Most commercially produced cannabis today comes from “sinsemilla” a Spanish word meaning “without seeds” plants that are female and never pollinated. These plants direct all their energy into producing dense, resin-rich flowers instead of seeds.
The Cannabis Plant’s Key Parts
- Flower/Bud: The reproductive structure of the female plant; where cannabinoids and terpenes concentrate in trichomes
- Trichomes: Tiny crystal-like structures that coat the flower surface; contain THC, CBD, terpenes, and other cannabinoids
- Leaves: The fan leaves are the photosynthesis engines; trim leaves (smaller, close to buds) contain some trichomes
- Stems: Support structure; contain fiber but minimal cannabinoid content
- Roots: Anchor the plant and absorb water and nutrients from growing medium
The Cannabis Life Cycle: From Seed to Harvest
| Stage | Duration | What’s Happening |
|---|---|---|
| Germination | 2–7 days | Seed sprouts; taproot emerges; seedling breaks surface |
| Seedling | 2–3 weeks | First true leaves appear; plant establishes root system; requires light and gentle care |
| Vegetative | 3–16 weeks (flexible) | Rapid growth; stem, leaves, and root system develop; plant needs nitrogen-rich nutrition and long light cycles |
| Pre-flower | 1–2 weeks | Plant shows sex (male/female); growers remove males; females begin forming early flower sites |
| Flowering | 6–12 weeks (strain-dependent) | Buds develop and mature; trichomes grow dense with cannabinoids; THC peaks near end of flowering |
| Harvest | 1–3 days | Flowers are cut; careful timing affects THC/CBD ratio and terpene preservation |
| Drying | 7–14 days | Harvested plants hang in controlled environment; moisture slowly removed from flower |
| Curing | 2–8 weeks | Dried flower is stored in sealed containers; chemical processes continue; flavor and aroma develop |
What Cannabis Needs to Grow
Light
Light is the most critical variable in cannabis cultivation. Cannabis is photoperiodic meaning it transitions from vegetative growth to flowering based on the ratio of light hours to dark hours in a day.
- Vegetative growth: Triggered by 18+ hours of light per day (“long day” conditions)
- Flowering: Triggered by approximately 12 hours of light and 12 hours of uninterrupted darkness per day
Outdoor growers work with natural sunlight and seasonal light cycles. Indoor growers use artificial lighting (LEDs or high-pressure sodium lights) and control the light cycle manually. This is the primary mechanism behind indoor yield control growers can decide exactly when to trigger flowering by flipping their light timer.
This light relationship also explains the difference between indoor and outdoor cultivation a topic covered in depth in our indoor vs. outdoor cannabis guide.
Temperature and Humidity
Cannabis grows best in a specific temperature and humidity range that changes by growth stage:
- Vegetative stage: 70–85°F (21–29°C); 40–70% relative humidity
- Flowering stage: 65–80°F (18–26°C); 40–50% relative humidity (lower humidity reduces mold risk as dense buds develop)
- Late flowering and harvest: below 50% relative humidity to protect trichomes from moisture damage
Outdoor growing in Vermont’s climate means working within these constraints seasonally typically planting after the last frost in late spring and harvesting in September/October before the first hard freeze.
Water and Nutrients
Cannabis needs regular, consistent watering but overwatering is one of the most common mistakes new growers make. The roots need both water and oxygen, and waterlogged soil suffocates them.
Nutrient needs change by growth stage, which is why understanding the NPK (nitrogen-phosphorus-potassium) framework matters. Our cannabis fertilizer guide covers nutrient management in detail from organic inputs to synthetic formulas, and what the plant needs at each stage.
Growing Medium
Cannabis can be grown in several different mediums:
- Soil: The most common and forgiving medium, especially for beginners; living soil with beneficial microbes supports plant health and terpene development
- Coco coir: Made from coconut husks; inert medium (no nutrients of its own); requires precise nutrient feeding but produces clean, fast-growing plants
- Hydroponics: Plants grown in water-based nutrient solutions with no soil; faster growth and higher yields in experienced hands; less forgiving to mistakes
- Rockwool / Perlite blends: Inert media used in hydroponic and hybrid systems; excellent drainage and aeration
Harvesting, Drying, and Curing: Where Quality Is Made or Lost
The time from harvest to the finished product in a dispensary jar is often underappreciated by consumers. How cannabis is harvested, dried, and cured dramatically affects the final quality including potency, aroma, flavor, and the burn quality of the flower.
Harvest Timing
Most growers use a jeweler’s loupe or microscope to examine trichomes to determine the optimal harvest window:
- Clear trichomes: plant is not yet ready; THC is still developing
- Cloudy/milky trichomes: THC is at peak; more cerebral, energetic effect profile
- Amber trichomes: THC is beginning to degrade to CBN; more sedating, body-heavy effect profile
The ratio of cloudy to amber trichomes at harvest is a significant factor in the final effect character of the product an experienced grower chooses harvest timing deliberately based on the desired profile.
Drying
After harvest, cannabis must be dried slowly in a temperature- and humidity-controlled environment typically 60–70°F and 50–60% relative humidity for 7–14 days. Drying too fast (too hot, too dry) locks chlorophyll in the flower, producing a harsh, “green” taste. Drying too slow (too humid) invites mold.
Curing
Curing storing dried flower in sealed containers that are “burped” (opened briefly to release moisture) over weeks is where flavor and aroma fully develop. Enzymes and bacteria continue to break down sugars and chlorophyll. Terpenes stabilize and mature. Well-cured cannabis has a noticeably more complex aroma and smoother quality than uncured or poorly cured product.
A minimum 2-week cure is standard; 4–8 weeks of curing produces significantly better quality. Top-shelf dispensary flower typically reflects a proper cure. This is one reason fresh dispensary flower from a quality producer can taste markedly different from cannabis that’s been rushed to market.
How Cultivation Choices Connect to What’s in Your Dispensary
Every cultivation decision growing medium, nutrient program, light environment, harvest timing, drying and curing protocol shows up in the product you purchase at a dispensary. This is why two products labeled “Blue Dream” from different producers can taste, smell, and feel noticeably different.
Key variables that affect final product quality:
- Growing medium: Living soil tends to produce more terpene complexity; hydroponic can produce higher yields but sometimes less flavor depth
- Indoor vs. outdoor: Indoor offers consistent, dense, visually premium buds; outdoor and greenhouse often develop richer terpene profiles from natural light and soil biology
- Nutrient program: Organic inputs tend to support more complex terpene development; synthetic nutrients offer precision but can leave residues if not flushed properly
- Harvest timing: Precise timing produces the intended cannabinoid and effect profile; early or late harvest shifts this significantly
- Cure quality: Proper curing transforms decent flower into excellent flower; inadequate curing is one of the most common sources of disappointing cannabis
Vermont’s cannabis testing standards require that all licensed producers submit flower and other products for independent lab testing before they can be sold including testing for potency, pesticide residues, and microbial contamination. This oversight is part of what makes licensed Vermont dispensary products trustworthy.

Frequently Asked Questions About Cannabis Cultivation
How long does it take to grow cannabis?
From seed to harvest, cannabis typically takes 10–26 weeks depending on the strain and growing environment. The vegetative stage is the most flexible (growers can extend or shorten it). Flowering takes 6–12 weeks depending on genetics. Add 2–4 weeks for drying and curing, and 2–8 more weeks for proper cure quality. Commercial producers optimize for speed without sacrificing quality; craft growers often allow longer cure times.
What makes some cannabis more potent than others?
Potency (THC percentage) is influenced by genetics (the strain), growing conditions (light quality and intensity, temperature, nutrients), stress during flowering (some controlled stress can increase resin production), and harvest timing. Indoor growing with optimized lighting tends to produce higher and more consistent THC percentages. Outdoor and greenhouse cannabis can be excellent in quality but may have lower or more variable THC percentages depending on the season.
Can I legally grow cannabis in Vermont?
Yes adults 21 and older in Vermont may legally cultivate up to 6 cannabis plants at home, with no more than 3 mature flowering plants at any time. Plants must not be visible from public spaces, and home-grown cannabis cannot be sold. Vermont’s home cultivation rules are administered by the Vermont Cannabis Control Board.
