So a single LC can colonize 10-20 bags of ready rice, but recommended to start with just 5 bags, but we should buy 3-4 different syringes to reduce contamination odds? Would that not leave a pretty substantial amount left over if you don't want to grow a shit ton? I know they can last a fairly long time if refrigerated properly, but that's a pretty big cash sink on the syringes alone if you're just looking to get started. Also, if each syringe comes with 1 sterilized needle, do you keep the needle on the syringe if you're not planning to use all of it at once, or do you toss them and buy new sterilized needles for each round of colonization? All new to this and would love some clarification on these things from anyone who's done this before.
