Once wrapped and placed in a loose Baggie for 24hrs, don't believe that's enough time for mold to develop. After that you seal a meal the cob and suck all the air out. No air no mold.
Your not puttin wet bud in the cob, your using bud were the stem bends but does not snap. Hang dry as normal, crispy on the outside, moist on the inside.
For sure you should be experienced in drying and curing your harvest. I wouldn't recommend it to someone that isn't up to speed drying.
I've seen guys hang dry way to long nod then jar up, never having to burp as the weed is to dry to start with. Makes for some harsh tokes. Then I've seen were its hung dry right to the point the stem snaps, and then jarred, but never burped and smells rotten, tokes like crap, and leaves a lump of black charred bud in the bowl.
Most all of us understand jar curing, and the diff it makes in the toke. For me, my jarred bud is still moist and tacky, I think there should still be some tackyness to the buds done right. Of course I do t get it right everytime, sometimes a bit to dry.
If you pull a bud from the jar and it easily crushes up between your thumb and fore finger then IMO it's to dry to toke, well dried and cured bud should need a grinder or thumb nail to bust up.
But everyone has there own idea of what good cured weed should be like and what they prefer.
As far as a cob, practice makes perfect, you may mess some up first go, I'm sure it's a learned technique, and much like hash making, some plants make great hash some don't.
Much like bho, if you use your best product you get some crazy potent goods, if your just using a botched harvest/ grow to get something outta it, you get crappy bho.
Also indica and hybrids aren't meant for this process, for what ever reason(density) ? So if your looking to produce some serious, potent, magic smoke ya need to get to growing Sativa/ Sativa Dom lines for the process.
