I'm dabbling with blends of peat, coir, and perlite, in starter and 4" pot-up mixes, to much satisfaction. Yes please tell me all you know, and especially anyting pertaining to preference of fabric, plastic, and poly-growbag containers.
I've only worked with a couple of brands, neither was what's coined, chunk or natural. Both were block, an Australian, nutrifield nf coco, and the other a GenHyd product Coco-Tek.
75% coco-coir/ 25% perlite is my favorite so far
Easier to wet after drying out than peat. And mixed in with peat at even 20%, it makes those overall mixes nearly as easy to water as the straight coir was.
Water retention seems about the same coco vs peat on the small pots, interested to see if that translates to larger pots.
Compaction seems less on the coir.
