I did it!
2 runs of about 600g total, outside.
I had to vape some Acapulco Gold courage to get started. Temps between -6 and -11 C.
I had to quit after 5 washes of the second run cause the washer froze up and I couldn’t drain it. I figured that was a sign.
I still have a third run worth of material so despite being at it for almost 10 hours yesterday I’m going again today. It’s a lot of set up and clean up, plus running the drying room for a week. This way I’ll get it all done at one time.
IWH is some work for sure, but I think it produces the best product.
