I have an update on the banana peel extract project, now on its 13th day:
I haven't been taking daily pictures because it really is unremarkable, and actually, sort of ugly.
The chunks of banana (grind it up next time} keep getting eaten up and if left to settle, a thick brown sludge forms at the bottom and around all of the chunks, which all just sink into the bottom together, leaving a little clearer liquid at the top.
It sits for days doing apparently nothing, until the other day when I went back to shaking it. Surprise! A lot of the sludge and banana debris disappeared into the solution. So it is breaking up, and the final liquid that results is going to be very thick and needing to be shaken well before applying.
I will be doing that applying on my next watering, which will be an AACT with heavy flowering nutrients and the microlife to support them, and everyone is going to love the banana!
