Mold in the jar

Damn it! Never had an issue with mold until today. Found mold growing on buds in two different jars of my higher grade nuggets. Thankfully it’s only 46g (1.6 oz) I’m throwing in the compost. It’s strange that it became an issue, as everything is approx 50-60% humidity in the jars, and i break-up large kolas into smaller nuggets.

Here’s a few pics if anyone is interested.

Only thing i can think of, is there was a few nuggets that were still too damp in the middle of a big kola. (I break up the biggies into grape size nugs when i jars them) must not have noticed when i was 16 hrs into final trimming)

Thankfully the jars are from a plant that was a 1lb plant....so i still have 14.5oz curing from this plant, and at my consumption level leaves me approximately 13 months of supply 🙂
 
Sorry to hear that... do you use any kind of humidity control within the jars, like Boveda packs or something?
 
This is why I take the final to be sealed jars to 45-50% RH before the final close of the jar. Mold can grow @ or above 55% RH. I lost some in the past and dont want it to happen again, I would rather it be a tad on the dry side, I can always let it set in my humid Oklahoma air for a while and it will gain moisture.
 
I just found that i had left my dang jar that i was burping open on my counter. I just harvested those 2 autos :( had them in individual jars half full boy they are now in 1 quart jar filled to the top.
 
The packs are designed to work slowly, like months slowly kind of slow. I don’t know how effective they are since i was still burping the jars every 2-3 days.
 
I can’t say if the Boveda was to blame. I think i just had a couple of nuggets that were still too damp going into the jars. 😒
 
There’s a very thin line between primo bud and mold. It’s even thinner now that I’m curing untrimmed. Boveda work great for long term storage once cured. I’ll toss one in and may not open or even check that jar again for months. The first month I use humidity meters and check my jars a few times a day, no boveda until cured. Here’s a chart I found on here a while back that’s a good reference.

Howdy YYCannabis, sorry to hear about the moldy bud! I had problems with mold in the jars during my first grow. I now use the smaller eight ounce jars for curing, just in case the mold does develop, it only spoils a smaller amount of bud. I also have been keeping the curing jars in the refrigerator to help keep the mold from forming in the first place. These steps have helped out a lot as I have not lost any more bud to mold, but it does seem to take a little longer to cure, but worth the wait. I let the buds dry to a crispy, but not crumbly state and I do not use any of the humidity packs, and do not open up (burping) the jars more than once a week. Every time the jars are opened, is another chance fro the mold spores to get into the jars.
 
DW2, can you tell me more about keeping your curing jars in the fridge to prevent mold? Is it just the lower temps, does that discourage mold growth?
 
Howdy Rik, The temperature (in my fridge) is around 41° to 43° F, and the low temperature is (most likely) responsible for the lack of mold growth, although, We all have had veggies and other stuff grow mold when left in the fridge too long. The lower level of moisture in the jars helps to 'curb' the mold growth as well. In the sealed environment of the jars, the bud is not subject to the higher humidity of the open stuff in the fridge.
 
I discovered the same thing recently with a jar.. that I’d been smoking for a few weeks before I found it on a big nug. Having to throw out quality cured bud was a bit sore! Think it’s my own fault for wanting to keep huge nugs
 
Damn what’s the best way to know if mold grew on them? Do I need a joyless loupe or is the mold visible to the naked eye? Does it smell like it shouldn’t smell? Just asking because now I want to check my buds being that I may have Jared them up early, though I open them daily. Does it make you sick right away? Or will it take time and eventually make you I’ll?
