after letting the indigo leaves compost for about 40 days I used the muck to create a fermentation vat. within about 4 days, with the use of the aquarium heater, the vat was producing color.
this is the culmination of a year long experiment of growing indigo for my own use here in the studio.
I do see why the leaves are composted entirely (mine weren’t ) but I always find that I learn more by testing and bending the status quo. I have new ideas for the next batch and will enjoy dyeing with this vat in addition to my other natural vat. the chem vat sits somewhat neglected other than its occasional use for special effects.
