Hi Dee!
Sorry about the issues you had. I think we all experience mold at least once in our growing experiences. As for the crispness the RH and temps are critical in the fridge. To a certain degree. You also want to have about an ounce of wet weed in each bag. Less than that and the process would be quicker too.
The process is a simple one. You want humidity levels at around 45-50% and temperatures at 40-45 degrees F.
I come preloaded so I’m good to go :rofl::cool: But probably like an ink jet printer, expensive to refill and needs so often.

The above link is a summary of the steps I use. My fridge hits those temps and RH levels as part of the normal operation of the fridge so if I had to guess the RH was too low as you surmised already. The temps are cool too so that would jive with the low RH. Warmer fridge temps and your RH should go up.
