Just returned from a week long trip. Unfortunately the weather cooled off to mid 50s and my color curing/drying leaf pretty much is all moldy. There might be a few leaves that aren't moldy but it will have to wait until daylight to know for sure. Any leaf that was brown and drying is moldy. I had a hand hanging from the first harvest all summer that had no mold but with the cooler temperature it succumbed to the mold. I think I should have pulled colored leaves to dry instead of leaving the hanging. I would have had good amount of leaf to age. I have a few more leaves to harvest but it is clear I will not be able to hang them in the shed any more. I might try towel curing inside.
My question to all you fine folks is how to proceed next year. If I have a good summer I can air cure. If its not a good summer I don't really know what to do. I think inside will be too dry and will end up with dry green leaf. Also the family won't like the wet dog smell of the curing rustica. I had planned on building a kiln to ferment the dried leaf. Can color curing be done rapidly in a kiln to reduce the risk of low ambient temps molding the leaf? Ideally curing is done in a week so I can swap out leaf with weekly harvests. Dry the cured leaf then kiln age it all at the end.
Up until this point air curing in the shed was going well. A disappointing learning experience but good to know the limits of curing tobacco in a temperate rainforest.
My basement is 50% humidity, so it's too dry for air curing. I tried the towel curing method for the first weeks of harvest, and it was horrible. Never again. Despite me tending to them at least twice a day (rearranging, wiping off excess moisture, etc), the leaves looked like they were rotting.
Instead, I got myself a wire rack (Costco) with a matching cover (Amazon), and hung my leaves there. For humidity, I just placed trays of water on the shelf, and I got 2 fans from Costco that swivel both side to side & up and down to get some airflow. That was enough to bump the humidity to low 60%s, and my leaves appear to colour cure fine.
As for the smell, my tobacco has a pleasant (to me, at least) hay scent. I am not growing any rustica, so I don't how how that would smell, but I don't think it should be much different
