Yeah it's about 2 months from start to finish and about 5-14 days to wait for the spores to germ if using a spore syringe.
Also I would advise against getting those kits as they are a ripoff and waste of money. You can find most if not all the stuff at walmart and lowes/home depot for a third of the price of those kits. (jars,brown rice,perlite,verm,1 6500k 26 watt daylight bulb, and a clear storage tote for a shotgun fruiting chamber).
