I have been reading this topic in bits and pieces for some time, I appreciate everyone sharing their experiences with them.

Is it even fair to compare grove bags with the one way valve type bags used for coffee? They let CO2 out but no air in. Itās especially important for roasted coffee not for green Unroasted beans.
I really appreciate the time everyone puts into this subject. I just ordered some grove bags and the wood moisture meter I saw here as well. Iām actually getting pretty fired up about the CURE. Itās kind of stupid for me to not invest whatever is necessary to preserve the final product but itās not an exact science, or is it?
Iām thinking it is.
If you can accurately measure the internal humidity of the vegetative material and can then store it just as you would fresh roasted coffee beans, you will reach a point where the conditions are perfect. At that point you either smoke it or store it. Coffee can be stored and sealed in a food saver type bag but Iām not sure it will retain its flavor profile. Iām gonna try putting some fresh roasted coffee in a grove bag and some in my canister with the one way valve.
Just trying to find another way to ask the same question I guess.

Even though I just posted this in another thread, I figured I would put it here as wellā¦ā¦
In July I harvested my autos and used a moisture meter to determine when the buds were ready to go into the Grove Bags.
I had been checking them for a few days and noticed the pins on the meter were pretty āgunked upā with resin. Before cleaning the pins I checked a bud a few times and was getting a consistent reading.
After cleaning the pins with alcohol I went back and checked the same bud a few times and was also getting a consistent reading. The problem was that the pre-clean readings and those post clean were noticeably different.
I canāt remember which were higher, or lower, I do know that, since then, I make sure to keep my pins cleanā¦ā¦

Do this with all of your measuring equipment whether it be ph probes, ppm probes, light sensors, humidity sensors, temp sensors, moisture probes, etc.

Absolutely! Another thing I do with all my measuring devices that use batteries is to swap out the cheap batteries that came with the device and replace them with fresh lithium batteriesā¦ā¦
I also donāt store any device for an extended period of time with the batteries left in them, especially alkaline batteries, which can leak. I used to be on a flashlight forum and the common term for alkaline batteries was, āalkaleaks.ā

Great advise! Nothing like opening the battery chamber to all the corrosion.

So the magic number is 11 percent moisture. When you bag it after that you should hold at 62 percent humidity. The moral to the story is dry your weed properly the first time and you shouldnāt have any problems. I like that. Also like that it stores better and smaller than jars. Not to mention there pretty cheap. Iām gonna do a jar to bag test as well, for personal preference.

Again thanks to all the contributions here. Iām still searching for a scientific zeitgeist moment and found this.

I hope you can help fact check it so to speak and if you find anything else like this pro or con Iād love to be tagged here

Iād appreciate somebody confirming my read of this that using coffee bag one way valves is not the same as using graves bags to preserve bud terpenes. If coffee loses its subtle olfactory profile, I imagine the buds do as well.
I did learn how to tell if one bag of coffee beans is fresher than another in the process.
Now when I shop Iāll get weird looks while checking my avocados for ripeness AND coffee beans for freshnessā¦lol
Onward through the fog
The valve can also help you determine which bag of coffee to buy. Over time, the aromas also escape through the valve along with carbon dioxide, so as your coffee ages, the smell becomes less potent. To check if a bag is fresh before you buy it, you can lightly squeeze the bag to release gas through the valve. A strong smell is a good indicator that the bag is fresh, and if you donāt smell much after a light squeeze, it probably means that the coffee has been on the shelf longer, and might not have as strong of a flavor.

Thanks dude
I just ordered some bags and didnāt think of that.
Then again I may be a bit too dense to understand even the experts lol
Iāve gotta clear it with the boss, but Iām pretty convinced the hard part for my harvest best practice will be tying up the spare room AND running another AC for a week or two.
Plan right now is to put the girls in opposite of GITMO
48 hours in the dark
No water boarding; no water at all
(Maybe some minor torture)
Then back into their former womb (4x4) for a week or two at a steady 60/60 temp/humidity and
THEN checked with my new toy (digital wood humidity device) and if they pass THAT hurdle, into the new bags for the final journey to cure.
This is getting to be complicated with new information coming to light; lots of ins and outs and what have youāsā¦.

I have my 2nd grow in them right now. Last cure turned out perfect in the bags and still smoking it after 6 months in the bags. Looks like it just went into the bags. Full of trics.

Just in case someone may want to have an idea on how much the bags themselves weigh, I just weighed 1 of each of mine.
I have a decent digital scale thatās only a few months old that has been used just a few times and I did a calibration just before getting the bag weights.
Iām betting that there is some variation in the bag weights, but this should be close.
Bag Size
1/8 oz. ~ 4 grams
1/4 oz. ~ 4.9 grams
1/2 oz. ~ 7.5 grams
1 oz. ~ 9.7 grams
1/4 lb. ~ 24.2 grams
1/2 lb. ~ 31.2 grams
1 lb. ~ 44.3 grams
