Yes even handwatered coco is hydroponics.
Screw the perlite, coco is so airy already, Canna Coco is 25%
air even when fully saturated with water. You can't over water
in it, you can fully saturate it several times in one day and not over
water it.
I've never had as good of growth as I am experiencing in my 100% canna
coco mix, using Humboldt Nutrient Master A&B line.
