Automated Curing Method
Anyone know of such a thing?
Basically it’s because I’ll be out of town for 5 days soon after a harvest and I’m worried about leaving buds too moist inside a mason jar without being able to burp them occasionally. On the flip side I don’t want to hang too long and over-dry harvested plants leaving not enough moisture within the buds to cure.
I’ve toyed around with the idea of putting ready to cure buds into large Mason jars with 2 tubes drilled into the top and an air pump timed to run for like a minute every 12 hours or so.
Does anyone else have suggestions or ideas or maybe even links to existing curing systems that are automatic?
I like the idea of a drying box but I’m worried about over-drying as well especially in the stage I’ll be at when I leave. For my last plant, not yet chopped, she’ll have 11 days to hang dry and jar cure. I was thinking that the 6-8 days of burping in the jars wouldn’t be enough for the RH to have lowered to an ideal range for long term storage. Allowing a minimal amount of air from the air pump tubing into mason jars would be OK provided that I could mimic the “burping” effect that a jar cured bud would get by putting an air-pump on a digital timer for 5 minutes every 6 hours for example.
As it stands right now I have enough time to hang dry my plants and get them started in jars but not enough time to properly ensure an exchange of air and the expulsion of overly humid air from the jars while I’m gone (for 5 days).
Using the hygrometer you can tell if the humidity is too high to leave them in the jars. I’ve also had good results putting the buds in the jars, but instead of using the metal disc center part of the lid (canning jar lids), I put a piece of paper towel over the jar and screw on the ring part of the lid. That way the jar can breathe a bit, but it is very slow. When used with properly dried buds, the humidity stays right around 60%,perfect for curing and no need to burp.
I think your air pump idea would work great, but you might want to use a hygrometer to help you figure out the proper amount of time to leave the pump on so as to get the right humidity level.
Thanks man. Yea I have a small digital hygrometer that I plan to use for this little project and I agree that this will be integral in adjusting an air pump timer to get the right RH.
I think I’ll just have the one tube going into the top of the mason jar and then a bunch of tiny hole poked into the lid of the jar to allow a small amount of air to ventilate out.
I’ll use your paper towel idea as well as moisture will likely collect near any fresh air openings like the tube openings near the top.
Since I’m only gone for 4-5 days it doesn’t have to be perfect but I just don’t want my buds to get mold from sitting in a jar w/out fresh air while I’m gone. Additionally since I’m only gone a short while I can dial in exact times for air exchange using a digital timer.
Since I have 2 plants that will be ready to jar in the next few days I’ll set up something and post pics.
Well I pieced together what I’ll be using to “auto-cure” a small amount of buds. Initial testing done on a few small buds in a large 1/2 gallon jar makes me think this will work great.
Here’s what I used:
1. Large 1/2 gallon jar. It’s not exactly a “mason” jar but it is glass and it does have a metal lid that screws on. About 10 inches of air-tubing (same kind used with air-stones). Small hygrometer. Air pump and digital timer.
2. Poked 2 holes in the lid using a small nail. One hole I pushed the nail in to increase the width enough to push an air-tube in and the other hole just large enough to let air out. The larger hole I had to push the air tubing in even though the tubing was a larger diameter than the hole. To push the tubing in the smaller hole I cut the end of the tubing diagonally and worked it in.
That’s pretty much it for set up. I placed the hygrometer inside the jar with a few small buds and screwed on the top of the jar. After about 20 minutes or so my RH jumped to 70% so I plugged in my air pump that was attached to the tubing and let it run for a few minutes. After 2-3 minutes my RH dropped to 58% and I unplugged my air pump. Again after about 15 minutes the RH rose again to around 70% so I plugged in the air pump again for a few minutes.
After the first few runs of the air pump it seems to do exactly what I want. The timer is thrown in so, depending on the RH of the buds that are in there I am able to exchange the air at precise intervals without me being there. I estimate that for my time gone I can get away with “autoburping” every 6 hours or so. I’ll be doing more testing tonight and will post pics as well.
