Has anyone done an experiment with 50/50 coco/perl vs 50/50 coco/verm?
I’ve always used perlite but this year I’m using auto pots on scale- 14 of them) and the grow shop I went to said vermiculite and coco is superior.
It makes sense as coco is light to begin with and vermiculite holds nutrients.
Also I have a mixture of both atm.
