I used these coco slabs i bought that you first put water on to make them expand/break. All the plants i used it for had stunted growth. I thought i had gotten crappy seeds and was about to toss them, but i noticed one plant that looked great and i remembered i had used old coco coir for that one (that coir looked more like soil, if i remember correctly it was quite expensive).
Any idea why these dried slabs are so crappy? This coir is not very much like soil, it's more like bark mixed with some soil. I did not use any Perlite. Was that the problem here, roots having problem penetrating the medium, it was quite tightly packed too.. or is it more likely to be PH-related?
I replanted all the stunted plants in the old/used soil-like coir and all plants looks great now.
I'm trying the slabs again but with 35% perlite for my clones, hope they will be fine but i'm slightly worried.
