I also heard that Bunnings coir is shit (on this forum) and may be heavy with trich spores. Someone recommended this brand in another thread - https://www.mypetwarehouse.com.au/ecotech-jungle-coco-peat-650gm-9l-fico01-p-17305 - I'm also on my first grow - going to spawn to that and verm tomorrow and see how I go I'll try some other brands of coir eventually because they are cheaper at Bunnings, but don't want to take a risk on my first tub just to save 5 bucks.
