Help with brown rice for cakes please

Okay so i just went to the store and picked up some verm, perlite, 1/2 pint jars (regular mouth) unfortunately.. I also picked up brown rice (whole) now my question is will this rice work.. Its called (china doll "natural" brown rice) my plan is to either blend this up really well or beat it to a powder, will this br (brown rice) work??? Thanks and happy tripping, my truffles just arrived in the mail mmmmm Psilocybe tampanensis
truffles, shipped straight to usa, florida

 

Problem # 1 is you cant get a cake out of a regular mouthed jar in one piece

Problem # 2 your rice might work or it might be coated with fungicides.... The only way to know is to use it. You may want to try rinsing it a few times before grinding it up. In the future try to get organic brf from a whole food store.

Problem # 3 Ps Tamps are difficult to grow and low yielding compared to Ps Cubes.

 

Im not growing ps tamps? I just ordered the truffles to try them thats all.. I actually ordered 2 spore syringes, one is b+ and the other golden teacher.. Also i can buy diffrent rice lol its no big deal, better to do it right the first time.. And ill just go by wide mouth jars thats all thanks for your help

 

I just realized my jars are tapered, so they will work fine, also i ordered "red mills organic brown rice flour" online, better to be safe then sorry. Thanks
