2l of 3% H2O2 into 100l of water. About.. going by the 2ml/l of 35% from the coir.com site. I guess less will fit into your barrel with the coco in it too, Archimedes with the eureka and all that.
I just boil my re use coco, new coco too, but lately my roots are too dense to easily
separate from the medium.
Cheap for me, a micro grower, to toss and replace with new.

It's quite some time ago now. I used canna zym between crops, then mild amounts for some time. My main take-away is not to. I can't quite remember the taste, but seem it think it was mushy. Not rotten or foul. Not even algae. Stagnant perhaps. An odd air about it.
Every substrate has it's flavour, and pebble are a harsh dusty smoke. The gain in organic flavour was very noticeable. Had I of changed compost brands or something, I might of expected such a thing. However, I was a chemical grower.
Reduce, Re-use, Re-Coco!!

I flush the last week of a grow with triple strength enzymes and then plant the new plants right into the old rootball.
The coco seems to get better with every grow.
If I've had gnats I'll add BTI to the last week and also the first two weeks of the new plants. The plants are loving it

Il reuse it a couple of times and as mentioned be sure to use some kind of zyme but I find after 2-3 crops it’s no longer coco and more like compost/ mulch so gets added to the garden outside.
