I've always been able to just wing it and jar cure my weed. But when I first started I let some mold on accident. But after a few years of learning I've got it down. I'm a bit older but I'm really considering trying one of these things.....it's always good to expand on your ways if someone shared the knowledge that's so helpful. What exactly are those things called again??? I'm gonna look on Amazon.....sorry I didn't read all pages either lol.
