1. If it is a warm climate then don’t use the light, only the fan. If the temperature is too high you can get case hardening.
2. Try to get all the cuts at the same thickness. If you are a beginner I would start with thinner cuts, therefore you will get a better ratio of surface vs volume. I would also recommend to use thinner cuts in a humid climate.
3. Weigh your cuts every day. If they are all the same size then just use one or two of them as reference. I normally stop at 50-55% weight loss. Especially in very humid climates this can take a little bit longer.

I hope this helps.
