> 70% humidity – When buds are too wet, your hygrometer will read greater than 70% relative humidity after buds are in jars with a hygrometer for 24 hours. If buds are very wet, you may see the humidity climb up this high within just a couple of hours. If you see the humidity rising on your hygrometer at a rate of 1% per hour or more, you may want open the jars early, or at least keep a close eye, as your buds are probably too moist.
Buds feel moist – If you shake the jar at this point, you may notice that some of your buds are still sticking together. You’re almost there, but buds are still a little too damp and you’re at risk for mold or anaerobic bacteria. If you live in a normal to dry climate, you may be able to get away with just leaving the top off the jars for 1-4 hours. If you live in a humid climate, you may have to take the buds out of the jars and lay them out until the outsides begin to feel dry again. 65-70% humidity – When buds are slightly moist, your hygrometer will read 65-70% relative humidity after buds are in jars with a hygrometer for 24 hours. Buds are not wet, but also not brittle – You’re in the cure zone! Buds should move independently and not clump together in big bunches when you shake the jars. 60-65% humidity – When buds are in the cure zone, your hygrometer will read 60-65% relative humidity after buds are in jars with a hygrometer for 24 hours. Some growers prefer to keep it a little lower during curing, down to around 55%, especially if they’re curing a whole lot of cannabis, because it helps prevent the chance of mold or “moist pockets” in the jars.
At this point, some growers add a Boveda 62 Humidipak to their curing jar with the buds to help keep the humidity in the correct range during the rest of the cure. (More on Boveda 62 packs below) Buds are too dry – Buds feel brittle and crumbly. At this point, there is not enough moisture in the jars for the curing process to continue at a normal pace, and buds tend to cure much more slowly. For those who struggle with curing even after going through all the steps in this curing tutorial, there’s a product known as a “Boveda 62” humidipaks which can help maintain the correct humidity in your jars. These are especially helpful at preventing the humidity from getting too low, even if the humidity is very low where you live. Some growers choose to use these every time they jar their buds to maintain the humidity in the 62% range. Boveda Humidipaks (62% version) are specifically made for cannabis and can help maintain humidity at 62%, as well as rehydrate buds. Humidipaks are used to regulate the humidity automatically. They were invented to keep cigars fresh in humidors (which is how they originally got their name), but the company now makes humidipaks that are specifically formulated for storing cannabis at the right humidity (as stated on their website). Note: Boveda is trying to move away from the term “humidipak” these days for some reason, but it’s such a perfect name! You simply place the little pouches inside with your buds after they’ve finished drying. Even when using Humidipaks, it’s important that you follow the rest of the steps outlined in this tutorial to ensure that your cure goes great. If you follow all the steps outlined in this article, you likely will not need Humidipaks. Most growers are able to cure their buds perfectly well without them. However, they can be helpful if you will be curing your buds in an environment with the incorrect humidity, especially if the air is really dry where you live. They can also be helpful if you’re not used to curing and are afraid of messing it up. Humidipaks also work very well for long-term storage. When we used them, they didn’t seem to lower the humidity when it was too high in our curing jars, but they did protect buds from drying out. Will Boveda 62 packs reduce the smell of your buds? Most growers seem to agree that these packs won’t reduce bud smell if they are added to the jars after the humidity has already been stabilized around 62% humidity for a few days. Keep opening all jars at least once/day for first 1-2 weeks of curing. For the first 1-2 weeks, whether or not you’re using Boveda 62 humidipaks, you should continue checking your buds regularly and opening all the jars once a day. Once you are sure buds have been steadily in the cure zone for a few weeks, you may start opening the jars just once/week or even less. If you feel like you’ve overdried your buds, don’t panic! Sometimes it feels like buds are too dry even when there is still moisture inside.
It’s a good idea to leave buds in jars for at least 2-3 days to see if moisture starts coming to the surface from inside. If buds still feel bone dry after a few days of being jarred, that’s when you might consider rehydrating buds. If you’ve only got household items, trying to re-hydrate buds afterward is risky and probably not a good idea. Re-hydration increases the risk of mold, especially if using something organic, like an orange peel, so use something that’s meant to do the re-hydrating. If you’ve been watching buds closely from the beginning, it is unlikely that buds will become over dry. However, if you have over-dried buds, one safe option to at least reduce the brittleness (freshen them up) is to add 62% Boveda Humidipaks to your jars, which will bring the humidity back up to 62% (they don’t work well for reducing humidity though – they can only raise the humidity and keeping it at the 62% level). These will help slowly infuse moisture back into your buds and won’t affect the taste or increase the chances of mold. Once the buds have been re-hydrated, you can remove the Humidipak if desired. Some growers have reported that leaving Humidipaks in jars during the first 4 weeks of curing can reduce the taste/smell of buds, though when we used Humidipaks during the curing process we didn’t notice any difference in smell or flavor.
As long as buds remain consistently in the cure zone after several weeks, you can begin to open jars once/month. Buds will continue to improve from curing for up to 6 months. After 6 months, further curing will not continue to have much effect.
