Months of work come down to one decision: when to cut. Harvest a week early and you lose potency you already grew; too late and the effect drifts heavy and sedative. The plant tells you exactly when it’s ready — you just need to know where to look.
Trichomes: the only clock that matters
Forget calendar weeks — ripeness lives in the trichomes, the resin glands coating your buds. You’ll need a jeweler’s loupe or macro phone lens (60x+) and you’ll check the frost on the buds themselves, not the sugar leaves.
- Clear trichomes — immature. Cannabinoids still developing. Wait.
- Milky/cloudy trichomes — peak THC. Energetic, potent effect. Most growers harvest at mostly cloudy.
- Amber trichomes — THC degrading into more sedative compounds. A common target: 70–90% cloudy with 10–30% amber for a balanced finish; more amber = heavier body effect.
Backup signal: when 70–90% of pistils have darkened and curled inward, you’re in the ripeness window — confirm with trichomes.
Pre-harvest checklist
- Final feeding: ease off nutrients in the last 1–2 weeks (plain water is fine).
- Timing: harvest at the start of the plant’s dark period or early morning outdoors — terpene levels are highest before light hits.
- Prepare the drying space first: you want lines hung and conditions dialed (see the drying guide) before anything is cut.
- Tools: sharp pruning shears, gloves (resin is relentless), trays, and labels if you’re running multiple strains.
How to harvest, step by step
- Cut branch by branch (or fell the whole plant for small grows). Branch-sized pieces are easiest to handle and hang.
- Remove the big fan leaves — the large, stemmed leaves with no resin. They only slow drying.
- Choose wet trim or dry trim:
- Wet trim — trim sugar leaves now, while they stick out. Easier scissor work, faster drying, better in humid climates.
- Dry trim — hang branches untrimmed and trim after drying. Slower drying protects terpenes; the choice of most quality-focused growers in normal climates.
- Hang immediately — into the dark drying space, buds untouched, air circulating around (not blowing on) them.
Staggered harvesting: a pro move
Top colas ripen before shaded lower buds. Harvest the ripe top third of the plant first, then give the lower buds another 5–10 days in stronger light — they’ll fatten and ripen properly instead of coming down early and airy.
Harvest FAQ
What yield should I expect?
Wet weight shrinks ~75–80% after drying. Indoor yields vary enormously with light and training — the yield figures on our product pages (g/m² indoor, g/plant outdoor) are realistic targets under good conditions.
Can I harvest in stages over weeks?
Yes — that’s staggered harvesting, and it’s often the best way to ripen an uneven canopy.
My buds smell like hay after cutting — did I ruin them?
No. Fresh-cut grass smell is normal chlorophyll; proper slow drying and curing (next guide) transforms it into the strain’s true aroma.
Next step: drying & curing
Harvest is halftime, not the finish line. The Drying & Curing Guide covers the stage that decides how your buds actually smoke. Or revisit flowering and the full Grow Guide.
