soil is one of those things where you cant belive what you herar.. ive never used ff, i make my own mix but the thing with soil is... you gotta know how to use it, just because some ppl say its great does not mean it will be great for you... some swear by ff being the best some say its crap some say maricle grow rocks some say its horibble.
so basically its up to you to find something that works for you... whatever you get i would recomend cutting with perlite and starting plants in peat plugs until roots are showing and transplanting into a small pot of the mix than repoting in like 2 weeks. transplanting getts you a lot of things one it helps with overwatering... the plant does not have roots to suck up all the watter in a big pot and could suffocate.... it also promotes a healthier root structure
dont feed for the first 3 weeks in any soil...
ff isn't really that week and if your gonna transplant it will get plenty from the soil.... less is more when it comes to feeding
