spore works' syringes are LOADED with spores too.
compared to microsupply.
im sure you could EASILY get a good 15-20 1/2 pint jars up and going in 3-4 weeks off of ONE 10cc syringe from sporeworks. (if you ration the fluid in the syringe during inoculation)
only good thing about microsupply is that you get a 12cc syringe for cheap.
the thing that sucks is that their syringes don't have much spores which means slower colonization.
