product includes 4 seperate, 3 lb bags of grainbspawn innoculated with luve mycelium. these are fully colonuzed, but innoculated as they are oredered with your choice of an “cubensis” strain listed in my products. species other than cubensis are not available ither than the ttbvi kit that is seperate from this. please note these may take up to a week to ship because i like to see strong, healthy , clean growth before send them in the mail.
