Cannabis Curing Guide using a Hygrometer and Jars

Step 1: The Dry
-Harvest and Hang
-3 to 14 days depending on relative humidity and temperature
-Keep it dark

Step 2: The Feel
-Buds start to “feel” dry
-Stems “feel” dry but are flexible and don’t snap when bent
-Time to jar the buds

Step 3: The Jar (65% - 70%)
-RH should be 70% at maximum
-The key in this phase is to get the RH down to 65% relatively
fast to prevent mold
-If hygrometer readings rise 1% an hour, this
indicates a high RH in the jar
-If RH is greater than 70% you need to leave the
lid off for 1 to 4 hours or even remove
from the jar if necessary depending on the RH
and temperature in the room
-Burp the jars for 1 to 2 hours per day to reach 65% RH
-It may take 24 hours to get a stable RH reading

Step 4: The Cure (60% - 65%)
-Looking for a much slower release of moisture.
-Burp jars for a very short period once a day
-Stable RH readings may take up to 36 hours

Step 5: The Smoke (60% to 55%)
-The cure continues
-It's ready to smoke
-Burp once a day until desired smoking RH is reached
-can be stored for longer periods up to 3 months
-Curing (65% to 55%) should take a minimum of 2 weeks
-Can cure as long as 1 to 6+ months

Step 6: The End
-The cure stops at 55%
-Ready for long term storage up to 3+ months/years?
-Can rehydrate to reach preferred smoking RH
-Rehydrating will not restart the cure process

I have been reading a lot about curing and some of the articles are long and cumbersome with others being very short. The main difference I came across was that some said you can cure for up to 4 years and others said that after 6 months there would not be any improvement.

I think this probably has to do with the type of effect you want from your cure. My estimation is 2 weeks to 6 months for a more euphoric? type of THC high.

The longer cures of 2 to 4 years would give more of a CBN "sleepy" high secondary to "THC being converted to non-psychoactive cannabinol (CBN)"

Yeah nice. I'll save the link to save typing out the whole hygrometer method when people ask. A quick bud washing 101 write up, and a link to the bud washing thread, and it should be in the FAQ - How to Grow Marijuana Everything You Need to Know. section, because this method is the easiest one, IMO, and it's not mentioned in there as far as I can see. Good work.
 
very informative. this needs to replace the sticky thread how to cure. That thread has numbers in it. What do you keep humidity and temp at? yours has it all. Thanks man, been looking forever on this topic. Link saved, gonna give it a shot

Considering I stealth grow, Temps and humidity vary depending on the time of year. I don't honestly know the best temp/humidity for drying. Since I don't really control my humidity at all I never thought about it much.

I don't have a temp controlled room for hanging:

The only thing I do for high humidity days when hanging is have a small fan blowing for air movement.
Low humidity and high temps, I hang for less days.

After jarring I try to place them in an temp controlled room 70 to 75 degrees.

Temperature:


Experts have learned that the ideal level of temperature is from 18.3 to 23.8 degrees Celsius (65 °F to 75 °F). When temperature is below the minimum 18.3 degrees (65 degrees Fahrenheit), the drying process will go very slowly. Going over the advised 23.8 degrees (75 degrees Fahrenheit) will indeed dry the buds faster and may cause a poor taste. Just keep the temperature within the optimum range and your weeds will be fine.

Humidity:

Humidity should be from 45% to 55%.

Thanks for all your research, knowledge and the posting of it. First time grower here and with all the information out there I don’t know which way to go. I know I have a lot to learn but you have to start somewhere. Thanks again

"Experts" lol. The absolute best cure is freeze drying. Nothing else comes close to preserving the flavour. I discovered this accidentally when curing a crop in the winter in a drying cabinet that drew air from outside through a dryer vent tube. Incoming air was minus 4 to 8 degrees Celsius and obviously very low humidity. Outstanding results!
