I squinted at the Noma images and found all the same equipment, except the humidifier (more below).
Here’s the setup:

I saw posts about cost, so the Inkbird duo are $73 and work very well.
The headache was the humidifier. The first two I tried had press-on power buttons. The problem is that the humidistat cant turn on the new press-on power buttons. I finally found a turn-dial power switch (not easy, as all small humidifiers have the cheaper press-on buttons) and, once turned on, the Inkbird can cycle the humidifier off and then on again. Use a small bottle of mineral water.
The koji isn’t that hard, and you of course need the humidistat and humidifier for it. I haven’t used dried. I used brown rice because my wife is gluten-free.
The advantage of making your own koji is that you can use it in other ways, as the book suggests. Fried as croutons is nice. It is an odd apricot-y sweet taste and takes a bit of getting used to, but I personally like it (and my kids hate it, which means it must be good). And it’s great for the gut biome....
Be advised that you cannot use the chamber and plant mat for the garum - the mat won’t go above about 108°. After realizing that, I went to my oven, and I’m lucky enough to have an oven that has a Warm setting AND a Sabbath mode, so I could keep it going 24/7 (Warm mode shut off after 12 hours, and I had to reset, until I called Wolf and they mentioned Sabbath mode).
Otherwise, it’s straightforward. Saran Wrap for the anaerobic environment, with a slight gap to release gas. Stirring and fat removal every 3 days the first three weeks, then stirring once a week. Change the Saran Wrap each time.
