Fans only cool humans, they don't cool plants but it's good to have some air movement when drying. If the buds are still clumping together after being in jars for 7 days, I'd be surprised if you don't have some mold by now.
To summarize what you should be looking for when jarring -
- Drying - Buds should be dried adequately for a twig to snap when bent.
- Buds WILL moisten up when jarred, assuming they aren't dried to dust.
- After the first day in the jar, dump them out. If you have to pull the individual buds apart, they need to be dumped in a paper bag for 4 - 8 hours, then back in the jar.
- Check again on day 2. Buds should a bit firmer and should separate more easily. Either repeat in paper bag or dump onto paper plate and leave out for a couple hours.
- Day 3 - Continue dumping out as necessary if the buds are still soft enough to stick together.
- Day 4 or whenever - when you can rotate the jar and the buds separate by themselves without you having to pull them apart, your getting close to 'dry enough'.
- Day 5 - 7. You should be able to hear the buds make little 'clinking' sounds and they should separate nicely as you spin the jars around.
- Open and check daily, looking and smelling for any sign of moisture or mold.
