The last two weeks decide the last five months

You fed it, trained it, watched the humidity every night. Then the harvest dries too fast in a warm closet, and the jar smells like cut grass.

It happens to careful growers all the time. Drying and curing feel like the easy part, so they get rushed.

They are not the easy part. Aroma, smoothness and shelf life are won or lost here. The good news is that the method is simple. Cool, dark, slow, and checked every day. This issue walks you through it, from the first look through a loupe to a jar that keeps for months.

Harvest by trichomes, not the calendar

Your strain's flowering window tells you when to start looking. The trichomes tell you when to cut.

Use a 60x loupe or a clip on phone lens. Look at the resin heads on the flowers themselves, not on the sugar leaves, which ripen early and fool people.

Heads start clear, like tiny glass. They turn cloudy, like frosted glass, as they ripen. Later, some turn amber. Check several buds from the top and the middle of the plant, since the top ripens first.

Reading the resin heads

Wet trim or dry trim

Both work. Choose by your room, not by habit.

The drying room: 60 and 60

Aim for about 60 F and 60 percent relative humidity, in the dark, for 7 to 14 days. That is the whole recipe.

Cool air slows the escape of the aromatic compounds you grew for. Moderate humidity lets moisture leave the inside of the bud at the same pace as the outside. Darkness protects the resin from light.

Hang whole branches, or lay buds on mesh racks, not touching, and turn them daily. Move the air gently around the room, never straight at the buds. Keep the exhaust low and steady.

Drying, day by day

The stem snap test

Take a small stem, about the size of a match, and bend it.

If it folds and stays bendy, wait. There is still water in the middle of the buds.

If it snaps with a clean little crack, it is ready for the jar. The thickest main stems may still bend a bit, and that is fine. Judge by the small ones.

The bud itself should feel dry on the outside and slightly springy when you squeeze it gently. Crumbly means it went too far. Spongy means not yet.

Into the jars

Use airtight glass jars. Fill each one about three quarters full, loosely, so air can move between buds. Do not pack them down.

Drop a small hygrometer in at least one jar per batch. Seal, then set the jars somewhere cool, dark and steady, around 60 to 68 F.

Read the hygrometer after 12 to 24 hours. The moisture left deep in the buds will move out to the surface, and the jar will tell you whether you jarred too early. Your target inside the jar is 58 to 62 percent.

The burp schedule

Burping means opening the jar to swap damp air for fresh.

What the jar hygrometer is telling you

Humidity packs, used well

Two way humidity packs hold a jar at a set level, usually 58 or 62 percent. They add moisture when the air is dry and absorb a little when it is damp.

Use them once the jar already reads in range. They are a maintenance tool, not a rescue for wet buds. A pack cannot pull out enough water to save a jar that went in too early.

Size the pack to the amount of flower in the jar, following the maker's guide. Swap it when it turns stiff and crunchy.

Mold: the signs to know

Check every jar on every burp. Look, then smell.

• Gray or brown mushy spots deep inside a bud.
• White fuzz or fine cottony threads on the surface.
• An ammonia or sharp musty smell when you open the lid.
• Buds that feel damp days after jarring.
• A hay or cut grass smell is not mold. It means the dry went too fast, and it often fades with a long cure.

The long cure

After two weeks in the jar, most flower is ready to enjoy. Give it four to eight weeks and many growers find it smoother, with a fuller aroma (a common belief, not something research has measured). Some growers keep going for months.

Once the jars hold steady at 58 to 62 percent, the work is simple. Keep them cool, dark and still. Heat and light are the enemies now. Check them weekly, then less often once they have been steady for a while.

Taste a little at week two, week four and week eight, and write down what changed. That record is how you learn your own sweet spot.

Five mistakes that cost the most

• Drying in a warm room because it was the only dark space. Find somewhere cooler.
• Pointing a fan straight at hanging buds.
• Jarring because the outside feels dry, without doing the snap test.
• Packing jars full to the lid.
• Skipping the first week of burps because a humidity pack is in the jar.

Dry and cure checklist

• Trichomes checked on several buds, top and middle.
• Room set to about 60 F and 60% RH, dark, gentle air.
• Snap test passed on small stems, usually day 7 to 14.
• Jars three quarters full with a hygrometer inside.
• Daily burps for week one, then weekly.
• Jar RH holding at 58 to 62%, every jar labeled and dated.

Let your phone count the days

If you would like help keeping track, Canna GLAP can send a harvest straight to stock, mark each batch as drying, curing or stored, and give it its own lot number with a day count.

Put your burp schedule on your list and note every jar's RH as you go. Cannie can help you read the numbers if a jar looks off.

Your journal is encrypted on your phone before it is stored. We cannot read it. It is there whenever you want it.
