Great to hear.
I also used a 'Tote around that size (76l), drilled 10mm holes along the perimeter at the bottom and made a 120mm hole in the lid where I have a 12v fan running at 3.7v to draw air out. I initially used an inline resistor to make the fan draw even less airflow, but I think it was too slow to make a difference.
The only difference is that I don't have a light inside mine, so I am hoping the air is dry enough for it to cure properly. I have mine sitting in my garage, and it's around 15 degrees give or take right now. The garage is the coolest part of the house, and the temperature is pretty stable.
I got some Chilli Bite spices from Freddy Hirsch as well, which I will try with the next batch. I went a little overboard and bought 5kg of rump to use, of which I have used around a third so far. I am reluctant to use the rest until I know my recipe is good - which, in hindsight, means I should have bought maybe 1 or 2 kg to start off with.
Will it be fine if I freeze the leftover meat to use at a later stage, or will this affect the quality of the final product?
