I personally would suggest Mycotopia over the Shroomery but that said, what everyone has stated here is right on. I moved on from PF tek after 2 grows simply because it didnt produce much for me. The main benefit is that you dont NEED a PC with it. Once you invest in one though it will make things more available to you. Make your own spawn bags with Wild Bird Seed (WBS)or other grains if you want. sterilize syringes and make LC or Grain to grain jars or bag to bag.

  I do bulk grows now with a large tub/bin from whichever big box store you like. You can buy presterilized grain bags these days and you will get A LOT more fruits with one of those than several cakes. So probably a 5$ tub, 10$ grain bag, homeade bag works out to a couple dollars worth of wild bird seed (no cracked corn)and a 30 to 50 cent bag (I PC my own though, got sick of washing jars and bags are so easy to shake or crumble right in the bag + It has an air patch already on it vs making one on a jar with a tyvek envelope/silicone or whatever) a 2$ block of coco coir= 17$ . Usually I dont even use vermiculite or any additives to keep time and cost down. Just colonize a grain bag, crumble and mix in the tub with fine brick coco coir for lizards ect. Keep as clean as possible always. When tub mix is again colonized you start fanning and misting daily. If all goes well you should be able to get at least a couple oz.( probably more if you were clean and take care of it) Double or triple those things and do the same as far as your fruits since you are already doing it anyways.  Then you can even make your own prints from your own fruit and basicly its a self sustaining hobby.
